The HD Guru’s readers have asked for the real story on power line conditioners. Are they really needed with an HDTV? Do they provide a sharper picture as some salesmen claim? How well do they protect the TV in case of a lightening strike or other electrical spike? What about surge protectors and uninterruptible power supplies (UPS)? The HD Guru responds.

In the United States the alternating current (AC) sent from your electric company should be delivered to your home at a steady rate of 120 volts at 60 cycles per second. In some parts of the US, there are variations, resulting in voltages that are either too high or too low. Sometimes interruptions cut the power altogether. Delivery of too much power is called a voltage surge; too little, a voltage droop or sag. Electrical storms can deliver lightening strikes, which can produce catastrophic voltage surges capable of destroying the power supplies of all the electronics plugged into the system, whether they’re powered up or not. Air conditioner and refrigerator motors powering on and off can also cause momentary voltage fluctuations. Another potential power problem is electrical interference caused by industrial grade electrical equipment operating nearby as would be found in a factory. Your home’s wiring may also pick up electrical line interference or radio frequency interference (RFI) caused by, among other things, broadcast transmitters located in your vicinity.

Fluctuating voltages can cause lights to brighten and dim. TV, lights and other electrical devices may momentarily shut off due to total voltage dropouts. Radio frequency interference can create hum and/or video noise bars and static.

Power conditioners can’t give your digital HDTV a sharper picture or better color, regardless of display technology, whether plasma, LCD, DLP, SXRD, or DILA rear projection. Period. Resolution is, by definition fixed, and so cannot be increased. If a salesman tells you otherwise, ask why are there no power conditioners connected to the dozens of TVs on display. All HDTVs have internal power supplies designed to filter and transform the incoming AC to voltages necessary for the set’s operational needs. These built-in power supplies do a great job, and are designed to accept a fairly wide range of line voltages. Can a power conditioner clean up heavy interference in your power line? Yes, but most of the time they are simply not necessary and will be of no use because the vast majority of households are free of electrical interference.

While power conditioners cannot improve your picture, a surge protector can protect your set in the event of a power surge. What’s needed depends on the display and the amount of protection you can afford. For LCDs and plasmas the HD Guru suggests a surge protector at the very minimum. According to experts, the rating should be at least 360 joules. These are very inexpensive, with prices starting at under $20. For lamp driven devices such as microdisplay front and rear projectors, including LCOS (Sony SXRD and JVC DiLA), DLP and LCD, you should purchase an uninterruptible power supplies (UPS). The HD Guru also recommends using the UPS with digital video recorders (DVRs like TiVo). A UPS will prevent the lamp’s cooling fan motor (or hard drive in the DVR) from shutting off during a power failure. You need just enough battery power to cool off the projector to prevent premature lamp failure or a DVR’s power down. 10 minutes worth of battery back up is more than sufficient. Virtually all UPS units also have built-in surge protection.

UPSs’ are either on-line or off-line designs. The on-lines are best because they actively filter and convert AC wall power into DC (Direct Current) to charge the battery, while simultaneously converting the DC back to AC to run your HDTV or DVR. In addition to offering excellent line conditioning, on-line UPS systems provide surge protection. Because it’s “on-line” there is no voltage drop when the AC power fails. The switch to battery backup is seamless.

The Tripp-Lite SU750XL is a good on-line UPS. Rated at 750VA, it will run a 500-watt load for about 10 minutes, which is plenty of time to cool off the lamp in any projector or properly shut down a TiVo. While it retails for $449, a quick internet search found it for $288.93 + shipping.

Depending upon capacity off-line UPS prices start at around $40. Because the AC in/out circuitry is not coupled to the output there’s around a 1-millisecond switch between line current and battery power. Virtually all have built-in surge protection and many of the mid size and larger one also have line conditioners.

Bottom line? Instead of selecting a line conditioner with surge protection, which can cost up to $500 or more, get first-rate protection that includes surge and battery backup plus top quality line conditioning, for under $300 by purchasing an on-line UPS. For under $100 you can be protected from the most common surge and short-term power loss problems with a UPS with surge protection combo.

With your ever-growing collection of electronic devices, perhaps it seems your home never has enough power outlets. Power strips and their more elaborate siblings, surge protectors, offer an easy solution: one plug in the wall, many outlets for your devices. But wait! There"s more to these simple-seeming products than meets the eye.

Adding additional AC outlets and USB charging ports is incredibly useful, and often vital. Don"t waste money on the wrong one, however. Here"s everything you need to know about power strips and surge protectors.

Typically, power strips are cheap, multioutlet products that are merely an expansion of a wall outlet. They"re usually small and thin, sometimes fitting directly onto the outlet itself. They usually have a circuit breaker (on/off switch) of some sort, but most don"t offer any real "protection" from electrical issues. Some might have the barest level of protection, but they"re all pretty much just like plugging into the wall directly.

Surge protectors are relatively cheap too, but unlike power strips they offer some level of protection. As their name suggests, surge protectors protect your products from power surges at the expense of itself. But more on that in a moment. How much they do this, and how well varies considerably. They"re usually a bit more elaborate, and often bigger, than a simple power strip, though not always.

Surge protectors offer protection in units called joules. Generally, the more joules the better, as this means the device can handle one large surge, or multiple smaller surges, before your gear is in danger. Over time, the parts inside the protector wear down, reducing its effectiveness.

Unfortunately, there"s no way to know how much protection a device has left, or if the initial rating is even accurate. Buying from a reputable company, and one that includes a warranty, is a good idea.

Some surge protectors offer a warranty (up to a certain amount) on the gear connected to the protector. For example, in the US, certain Belkin models have up to $300,000 in connected equipment warranty, and states: "Belkin Components will repair or replace, at its option, any equipment which is damaged by a transient voltage surge/spike or lightning strike, (an "Occurrence"), while properly connected through a Belkin Surge Protector to a properly wired AC power line with protective ground."

You"ll probably never need it, but it certainly doesn"t hurt to have it. Keep in mind, however, that just because the warranty exists doesn"t mean you"ll ever see a dime from it. Note in that Belkin quote the term "at its option." That means they"ll come up with any reason not to cover your claim. So don"t use this as a replacement for home or renter"s insurance.

You"re always going to need more outlets. You"ll undoubtedly add more gear, without necessarily getting rid of your current gear. I"m not saying that if you think you need four outlets, you should get 12 -- but at least six is probably a good investment.

Most modern devices use "wall warts" -- plugs that convert AC power into DC power and look like little boxes with electrical prongs sticking out. Consider getting a surge protector with wider spacing between sockets, or sockets that can be rotated or moved, to accommodate chunky plugs.

Many surge protectors come with USB connections, so you can charge your mobile devices without having to use their wall warts. Handy, for sure, but check what the output amp rating is. Generally, this is either 1 or 2 amps (often labeled 1A or 2A). This is how much flow you can get through the pipe, so to speak. You"ll want at least 2 amps for quicker charging.

Most modern phones have the ability to fast-charge, but you"ll need to use their wall warts for that. If you don"t need to quickly charge them, though, these lower power ports will work just fine.

While not offering much protection, a portable power strip might prevent marital friction, and/or invoke bliss from travel companions. Most hotels and hostels have few accessible outlets, yet everyone has multiple devices that need recharging. Most portable power strips add two to three additional outlets, plus offer direct USB charging (see No. 8, above).

Remember the joule rating we discussed earlier? This is just the initial rating. This gets lower over time. In other words, surge protectors wear out. Some will give you a warning or shut off when their protection drops below a safe level. Many will just keep working, without protection, and you won"t know it until a power spike damages your gear. If you know you"ve had a serious electrical event (like lightning blew out a transformer down the street), it"s probably worth replacing your surge protector just in case.

Most companies that sell surge protectors say they need to be replaced every three to five years. Sure, they"re motivated to have you buy them more often, but with many models under $50, this isn"t an extreme cost.

There is no reason not to get a surge protector over a simple power strip. If you live in an area with lots of thunderstorms, your gear is probably more likely to experience power surges. Even if you live in the desert, your AC or refrigerator could kick power spikes back down the lines to your AV gear. Either way, some extra protection for your gear is absolutely worth the small difference in price between simple power strips and surge protectors.

When used in the first case to divert power around a portion of the unit, the bypass may be acting to protect the unit itself from extraordinary conditions or provide power downstream if a portion of the unit malfunctions or is temporarily inoperable. For example, if UPS batteries are drained and cannot provide power to the load, many UPSs go into “bypass mode,” providing raw, unconditioned power to the load so it can remain online. (See electronic bypass.)

When used to isolate a unit (generally used for larger units), a bypass made of circuit breakers or disconnect devices electronically isolate incoming and outgoing “sides” of the voltage regulator/power conditioner from the system. The unit can then be safely isolated for maintenance while downstream devices receive unconditioned power to remain online.

Some voltage regulator/power conditioners are capable of taking incoming power at one voltage level and providing it at a lower voltage level at the output (for example, from 480 volts to 208 volts). This ability to “step down” the voltage can eliminate the need for a separate transformer to change the voltage to the proper level for the downstream devices. In some cases, a “step up” might also be useful.

Voltage that is too high can cause premature failure of electrical and electronic components (e.g. circuit boards) due to overheating. The damage caused by overheating is cumulative and irreversible. Frequent episodes of mild overheating can result in the same amount of component damage as a few episodes of severe overheating. Like slicing a loaf of bread – you can have many thin slices or a few really thick slices – but when you get to the end, you’re done.

Motors can, on the other hand, often benefit from voltages that tend to be a little bit high. The reason is fairly simple. As the voltage level goes up, the current is reduced and lower current usually equates to less heat generation within the motor windings. There is a point where the voltage level supplied can be so high as to damage a motor but this level is far higher than that for electronics.

Keeping electrical and electronic components cool tends to insure their longevity. Slight reductions in voltage levels may permit many electronics to perform perfectly well while minimizing their temperature. Of course, the same is not true of motors.

Just as higher voltages can help reduce motor operating temperatures, low voltage is a major cause of motor overheating and premature failure. A low voltage forces a motor to draw extra current to deliver the power expected of it thus overheating the motor windings. The rule of thumb for motors is “for every 10 degrees C (50 degrees F) a motor is operated above its rated temperature, motor life will be decreased by 50%”.

More than motors and circuit boards are at risk for damage when voltage levels are bad, but chronic problems with either is often an indication of a voltage problem.

Your AC is a complex system made up of many interconnected parts. If any one part fails, the system can’t work at peak efficiency. But if the thermostat isn’t working, the whole air-conditioning system is down. The thermostat is the little box on your wall that controls the AC. No power to thermostat means you can’t turn your AC on or off, or set it to the right temperature.

When your thermostat loses power, there are a few simple things to check first. The very first thing to do is to make sure it’s actually turned on. This is especially something to check with older thermostats. As long as they are receiving power, newer digital thermostats will still show something on their displays, even when they are off. If your thermostat is digital and its display screen is completely blank, that likely means it has lost power.

If your home has an older thermostat, it also may be the kind that runs on batteries. As a rule of thumb, you should replace the batteries once a year to ensure that they keep working as they should. If your thermostat loses power, try replacing the batteries to see if that fixes the issue.

If the thermostat seems to be on and the batteries are good, or if it doesn’t have batteries, the next thing to check is the circuit breaker. Like everything in your home that runs on electricity, the thermostat is connected to a switch in your home’s circuit breaker. The system will automatically shut down if the circuit supplying electricity to your thermostat gets overloaded. The circuit will flip to the Off position.

It’s simple enough to look at your circuit breaker, see if the switch has turned off, and flip it back on again. Sometimes, this will fix the problem. Other times, the switch will turn off again. If this happens in your home, it signals you may need to upgrade your electrical panel or you may have some other problem that needs to be diagnosed by a professional.

If none of these steps fixes the problem, there is a different issue. Sometimes, a problem with the safety switch on your AC can cause the thermostat to lose power. Most AC safety switches are next to the drain pan. Excess moisture can trip this switch, causing the transformer to stop supplying power to the thermostat. If this has happened with your AC, it is a safety mechanism that needs to be inspected by a heating and cooling specialist to determine the cause.

A bad transformer or bad wiring can also cause your thermostat to go blank. Another possibility is simply that the thermostat is broken and needs replacing. All thermostats reach the end of their lifespan at some point. If yours is an older one, it’s a good idea to replace it with a programmable one. These thermostats save you money on your energy bills since you can pre-set your AC to temperatures that make sense for your day-to-day schedule and comfort level.

Smart thermostats are the latest version of programmable thermostats. You can control these remotely, from your phone or computer. This enables you not just to set your AC in advance based on your daily schedule, but also to make quick changes as needed if unexpected situations come up.

Some smart thermostats even allow you to set reminders to replace your AC filters at regular intervals. Changing out dirty filters is one of the simplest yet most important ways you can protect and extend the life of your AC. That makes reminders from a smart thermostat a very helpful function for lots of homeowners.

If you aren’t able to determine the reason why your thermostat is not working, it’s time to contact an HVAC specialist. A professional can inspect your AC system to figure out what went wrong. They can determine the right fix for the issue, to keep it from happening again. They can also schedule regular maintenance checks to extend the life of your AC and keep it running as efficiently as possible. This will save you money and keep you and your loved ones comfortable throughout the seasons.

When your thermostat is not working, it can sometimes be hard to tell whether it’s actually getting power. There are wires in the thermostat as well as in other parts of the AC system that sometimes get loose or corroded. They can even be damaged by rodent pests chewing on them. Wiring issues can cause power flow problems to the thermostat. Fortunately, it’s relatively simple to do a thermostat test to see if the wire is getting power.

The simplest wiring test doesn’t require any special equipment or knowledge. All you have to do is switch the Fan setting on your thermostat from Auto to On. Listen to see if you can hear the sound of the blower starting up. If you hear it, there is power getting to your thermostat.

Similarly, you can make sure your AC is on and set on the correct mode for the season—Cool for summer, or Heat for winter. Then turn the temperature setting either down (in summer) or up (in winter) by several degrees. Make sure it is set to a level that is either lower or higher than the temperature of the room you are in. If the thermostat wires are conducting power as they should be, you should hear the normal sounds of your AC starting up.

Beyond these simple tests, you can also test the wires themselves. To do this, you’ll need to take off the thermostat cover so you can see the wires that are behind it. If you take it off but you don’t see wiring, you may also need to use a screwdriver to remove a mounting plate that is covering the wires. Once you can see the wires, you should be looking at several different-colored wires attached to terminals marked with letters.

The voltage going through these wires is relatively low. But you should still turn off the power at the circuit breaker before you touch or disconnect them. Once you’ve turned off the power, you’ll want to pay attention to two main wires here. One is the red wire connected to the R terminal. The other is the green wire connected to the G terminal, which connects to the AC’s blower.

With the power turned off, disconnect the red and green wires, and twist their ends together. Then, turn the power back on. If these wires are conducting power as they should be, the AC blower will turn on.

You can also use a tool called a multimeter to check if the wires are working properly. You won’t need to turn off the power or disconnect any of the thermostat wires from their terminals. All you’ll need to do is to set your multimeter to measure 24 volts AC, and then touch one of the tool’s probes to the R terminal. Touch the other probe to either the G terminal, the W terminal or the Y terminal.

If there is power flowing to the thermostat, the multimeter should register a reading of somewhere between 22 and 26 volts. A reading of 0 volts indicates that there is no power getting through the wires.

Most homeowners don’t have multimeter tools lying around. And, it’s understandable to want to avoid DIY projects that require exposed wiring and the risk for electric shock. A professional can easily test your thermostat wiring to determine whether it is performing correctly. Then they can make any needed AC repairs to get your system running again.

If your thermostat breaks, you can hire an AC professional to replace it. But some people enjoy the challenge of learning how to change a thermostat themselves. It’s not a terribly complicated DIY job. Just make sure you install a new thermostat that is compatible with the rest of your heating and cooling system.

As with any job involving electricity, the first step in changing your thermostat is to first turn off your AC at the thermostat, and then turn off the power at the circuit box to avoid the risk of electric shock.

Next, you’ll need to take the old thermostat off the wall plate. The wires will be exposed. This is a good time to use a multimeter tool or a circuit tester to make sure the power is definitely off.

Take a look at the wires and the terminals each one connects to. Each wire should be a different color, and each should connect to a terminal marked by a different letter. Take a photo of the wiring so you can refer to it later if needed. Then use tape to mark each wire with the letter of the terminal it connects to. (The replacement thermostat you purchased may also come with new, pre-printed labels for you to use.)

If your replacement thermostat has mounting holes that happen to match the location of your existing wall anchors, you can reuse the old anchors. But it’s likely the new unit will have at least slightly differently spaced holes. If so, you’ll need to drill new holes in the right spots, and install new anchors.

Some people prefer to remove the old wall anchors and patch the holes before drilling new ones. If the new wall plate can be mounted flush to the wall where it covers the old holes completely, you can also simply leave the old holes as they are.

Next, it’s time to install the wall plate that goes with your new thermostat. Feed the wires through the opening in the plate so they are ready to connect. Be sure to use a level as you mount the plate so it’s straight.

Check the instructions that came with your new thermostat to make sure you insert each wire into the right terminal on the new unit. Then tighten the terminal screws. If your new unit requires a C wire and you don’t have one, you’ll probably need to call in a professional to finish the job.

Once you have installed the new thermostat, it’s time to turn the power back on to make sure it works. If anything went wrong during the installation process, it’s a good idea to reach out to an AC professional for help. A licensed specialist can handle any AC repair job, big or small, and keep your heating and cooling system running well. This will keep your monthly electricity costs as low as possible and extend the life of your AC system.

Thermostats are complicated and issues can arise for a number of reasons. Instead of trying to diagnose these issues yourself, contact ABC Home & Commercial Services. Our pros will efficiently diagnose the HVAC problem and get to work on fixing it. We even provide preventative AC maintenance so we can catch potential problems early.

Blinking lights on your air conditioner are usually a sign that there’s a problem with your AC unit. There are several reasons why your AC light may start blinking, but the good news is that many of them are easy to fix.

Here are some of the most common reasons why your system may show your AC light blinking, as well as the best practices to make sure your air conditioner functions properly.

You may be asking yourself, “Why is my ac light blinking?” We’re here to help! AC units are programmed to display a blinking light whenever they run into an issue or begin to malfunction.

Even if the issue is small, the system is designed to “report” problems as soon as they are discovered by displaying the AC light blinking. The blinking light is your AC unit’s way of letting you know that something isn’t quite right.

One of the most common reasons that AC units show a blinking light is that there are electrical problems. This could be because there is irregular power drawing or loading, and the printed circuit board or electrical wiring is experiencing some issues.

The first thing you should try is resetting your AC unit’s power switch. This could help sort out any problems, especially if the issue is the result of a power surge.

If Solution 1 doesn’t work, the next thing to do is to hire a professional to assess the extent of the electrical issues. This is not a problem that you should attempt to fix on your own, given the high possibility of danger or electrocution.

Your technician will be able to perform isolation testing and other tests to determine the root cause of the problem. They will then be able to recommend the next steps to take or the necessary parts that you may need to order to fix the problem.

Another potential reason for your AC light flashing is that your filter may be installed incorrectly or may be clogged. If the filter is clogged with dirt, your AC unit will struggle to produce clean air and won’t be able to cool the air as effectively. This can cause a number of issues, including water leakages.

Check the filter for your air conditioner regularly. Most air filters should be replaced every six to 12 months. Check to make sure the air filter is clean and also installed correctly. If you see any potential issues, take the steps to fix them. This may mean buying a replacement air filter.

Your light may also be blinking because your air conditioning unit needs a regular check-up. AC units need check-ups just like people, especially if they’re a little older or have been working especially hard.

Call a professional to come to check out your AC unit and make sure your unit is functioning properly and has everything it needs to run smoothly. They’ll be able to advise you on the next steps to take.

Your refrigerant levels may be low, causing your AC unit light to blink. All units have a required level of refrigerant, and they have a meter to measure how much is currently in the system. If your unit senses that your refrigerant levels have dipped below the recommended amount, the light will begin to blink.

This is another problem that needs to be solved with the help of a professional. Refrigerant is a chemical that should only be handled by experienced technicians.

AC units have parts called compressors that are essential to their function. If a compressor begins to fail, it is a problem that should be handled immediately. This is a common problem that happens during the summer. This is because air conditioners have to work extra hard during the hot months to create cold air. During this time, some parts of your unit may wear out more quickly than others.

To check if this is happening, look at the error codes presented by the unit. There should be a guide in your manual or online that can translate what each code means.

Consult a professional if this is the problem with your AC unit. They’ll be able to replace all the missing parts and get your unit in top shape in no time.

This could happen if your unit is positioned poorly or for several other reasons. This is another instance where you should check the error codes to find out if that’s what’s troubling your unit.

Your unit also may have been installed poorly. The light will also start blinking if this is the case, even if there are no problems within the unit itself. Believe it or not, it’s actually pretty easy to make a small error during installation that can cause problems down the line.

If the light is blinking on your air conditioner unit, it probably means that there are issues that can be easily fixed within the unit but that need to be addressed. If the problem persists, contact us at AHWA and we will send a professional your way to get your AC up and running in no time.

When the scorching Queensland heat returns in summer, many of us will be cranking our Daikin air conditioner to keep us in blissful comfort. Unfortunately, the system has to work hard to fight the oppressive heat, and as it grinds away for hours on end, its refrigerant depletes, its parts wear down faster, and eventually it’ll give up with a sad splutter, and you’ll be drenched with sweat faster than you can say “Crown Power.”

If you’re in a sticky situation like this, and you’d rather attempt your own fix before calling in the professionals, thisDaikin air conditioner troubleshootingguide will help you on your way. We tackle the most common questions that we receive from clients whose Daikin air conditioner has suddenly thrown down its tools and refused to work—everything from “why is my Daikin aircon not working?” to “what does this flashing green light mean?”

Daikin troubleshootingdoesn’t have to be arduous. In thisDaikin AC troubleshootingguide,we offer quick and easy tips on how to fix almost every issue you can think of, including whether it’s safe for you to do so.

You may be surprised to learn that if you’re having air con problems, you don’t necessarily need to call a technician out. Often, there’s an easy solution to get your air con up and working again, which is why we’ve created thisDaikin inverter troubleshootingguide.

Iftroubleshooting your Daikin air conditionerisn’t going as planned, and none of the suggestions below work, we recommend giving us a call. We’re authorised Daikin specialists, and are able to offer fast, affordable help.

Wondering why your Daikin inverter isn’t turning on? Here are a few simple checks you can do to figure out the problem, and reset your Daikin air conditioner.

Our experts recommend cleaning your air con filters once every two weeks in summer, when it’s used heavily. Otherwise, it’s okay to wash your air-purifying filter once every six months.

If your Daikin aircon is not cooling your room effectively, it may be a Daikin sensor problem. Sometimes, the sensor doesn’t detect people who are far away from the indoor unit. You can troubleshoot this by moving closer to the air con and checking that the air quantity and direction are properly controlled, and that the ventilation fan is moving.

If your Daikin air conditioner has a flashing green light, don’t panic. While there are a few different issues that can be indicated by a blinking green light, most of them are pretty easy fixes.

Search theDaikin air conditioning error codes page for your code. You can match the letter to the number to find out what is wrong, and contact your Daikin air con specialist.

If the timer lamp on your AC unit is flashing orange, the Streamer unit needs to be cleaned. To clean the unit, you can follow the instructions on page 36 (under Streamer unit) of thisDaikin guide.

If water is leaking from your indoor air con, unplug it and contact a professional. It is common for air conditioning units to produce some condensation, but a considerable leak could be a major safety issue, so do not touch the air con unit or attempt to fix it yourself.

This means that the dust box needs to be cleaned. To clean the dust box, you can follow the instructions on page 37 (under Dust box) of thisDaikin guide.

If this button on your remote or air conditioning unit is not working, unfortunately, you will need to contact the retailer who sold you the unit, or professional air conditioning technicians such as Crown Power.

If you’ve lost the remote control, you can turn the air conditioner unit on and off by pressing the ON/OFF button on the main unit. When this button is used, the AC will use its automatic settings.

Bubbling sound—this may be outdoor air entering the drain hose. Generally, this is normal and tends to happen in a well-sealed house, or if you’re living in an apartment.

Please don’t apply cleaning spray or odour spray to your air conditioning unit at any stage. It’s not necessary and may cause damage that will void your warranty.

If the filter is clogged and filthy, you can clean this easily by following the instructions in ourDaikin Air Conditioner Maintenance guide. If you’ve found a refrigerant leak, or believe that the coils are dirty, turn off your air con immediately to prevent further damage and call a reputable professional for assistance.

If your air con suddenly stops, or turns on and off repeatedly, this is usually nothing to worry about. When the unit stops unexpectedly, it’s usually protecting itself from voltage fluctuations, and should start working again within a few minutes.

When the temperature in your room reaches the set level the unit switches to “breeze mode” to maintain the temperature. When the temperature fluctuates, the unit will increase the volume of air flow. A stable room temperature is the goal of a good unit, so if this is happening, ourDaikin air conditioning troubleshootingguide recommends leaving this well alone.

If your heating stops unexpectedly and you hear the sound of water flowing, your outdoor unit is running its defrost operation. This should resolve itself in about 10 minutes.

This may be caused by frost on the unit. The pipes on the outdoor unit will get cold during cooling, which produces condensation and causes water to drip. This is usually nothing to worry about unless it causes other problems.

If the flap has been touched during operation, it may not close properly. This can easily be fixed by turning the unit on, giving it time to start, and then turning it off again.

If your auto filter cleaning setting is on, your Daikin AC will stop after 24 hours of continuous operation, complete the filter cleaning process, and resume normal operation. This is nothing to worry about.

If there’s a fault with the Daikin system, this will sometimes show on the remote control or wall-mounted controller. Or you may have to complete a sequence on the remote controller to get the code to appear, which Daikin explains inthis document.

It’s highly unlikely that you will be able to fix the fault yourself, but it can give you an idea of what might have gone wrong with the air conditioner. You can also pass the fault code onto the air conditioning technician when you call them so that they come fully prepared.

Power surges are both common and costly. According to IBM, every home or business gets hit every day by at least one surge measuring between 100 and 1,000 volts. The effects of a surge can be subtle or dramatic, depending on the surge’s duration, intensity, and whether the affected devices have adequate protection. Smaller surges destroy internal circuitry slowly, over the course of several months. Larger surges, on the other hand, inflict the same damage, but in less than a millisecond. If the surge is long enough and strong enough, it may even heat up the internal electronic circuits to the point that they catch fire. In addition to the obvious costs needed to replace damaged devices, surges also cause lost productivity (when employees are idle in business environments) and loss of use (when home theater equipment and appliances are idle in home environments).

Surge protectors protect against spikes and surges. They come in many configurations, and most include EMI/RFI filtering to decrease line noise and improve audio/video quality.

A surge protector should be sufficient for devices with lower inrush currents, like TVs and stereos. Their usefulness, however, depends on the protection you need. If your equipment is mission-critical or your facility experiences frequent outages, this might not be the solution for you.

And while surge protectors require less money up front, they often cost more in the long run, because they typically need to be replaced every few years.

Power conditioners not only protect against surges; they protect against brownouts as well. With built-in voltage regulators, they continuously monitor power, then condition it and keep it steady.

What a power conditioner will not provide is EMI/RFI shielding. If you want to improve video quality or decrease line noise, this might not be your best option.

While power conditioners cost more up front than surge protectors, they’re better suited for higher inrush devices like copiers and laser printers. Because they’re designed for devices that need ongoing power regulation, they’re often used in factories and hospitals.

A UPS can do everything a surge protector can do, but its main purpose is to reduce downtime that can cost your business money. And unlike a surge protector, a UPS features battery backup that allows equipment to stay up and running through power failures.

Like power conditioners, many UPS systems have voltage regulators. These models not only provide battery backup, but they also keep voltage at an acceptable level.

For a data center or server room, a UPS is your best option. They come in various configurations for both single- and 3-phase applications. Many also include special features, like LCD panels, hot-swappable batteries and energy-saving operation.

Is your air conditioner not cooling at all or not producing air that is cold enough to cool your home? Several AC issues can cause this problem. The solutions range from a quick and easy fix to requiring a professional HVAC technician, depending on the severity of the problem.

“ON” Setting: Setting your thermostat to “ON” will make your fan run continuously, circulating the air throughout your home and causing air to blow from your air vents even when your air conditioning system isn’t cooling the air.

“AUTO” Setting: Setting your thermostat to “AUTO” will cause your fan to only turn on during your air conditioning cycles. When the cycle finishes, your fan will turn off again.

Your AC system needs to intake air to cycle properly. A clogged air filter will reduce airflow and decrease the efficiency of the system and make it difficult to cool the air properly.

If your AC condenser the AC unit located outside) is blocked by leaves, bushes, trees, or other plants, it won’t be able to disperse as much heat to the surrounding area.

When the heat has nowhere to go, it will start to accumulate in the condenser unit, causing the condensing temperature to rise and the system to run inefficiently.

The dirt creates a layer of insulation between the air and the coils, making it harder for the coils to cool the air to the desired temperature. As a result, your AC will blow air that is warmer than it should be.

AC capacitors work like batteries. They’re used to power the motor in the compressor and blower fan. So if there’s a problem with your capacitor, the compressor won’t be able to function properly.

Hear a clicking sound coming from your AC unit? It’s a common sign your AC capacitor is beginning to fail. When your capacitor fails, the motor attached to it will hum instead of turn on. If this happens, turn off your AC system immediately as the motor could burn out and need to be replaced.

Since the problem may be with the capacitor powering the motor and not the motor itself, it’s important to have a professional HVAC technician diagnose this issue.

Your AC compressor’s role is to compress the refrigerant, raising its temperature and transporting it to the outdoor coil. This process collects the heat from inside your home and releases it outside.

Compressor problems are the most commonly misdiagnosed issues in an AC system. Many other AC problems create symptoms that look like a bad AC compressor, and multiple things can cause compressor failure, making it tricky to diagnose accurately.

If you believe this is your problem, it’s best to get the second opinion of an experienced HVAC technician to make sure you diagnose the problem correctly.

Refrigerant is dangerous, so it’s best to have a trained technician diagnose the issue, fix any leaks, and recharge your system with the proper amount of refrigerant.

If your AC system is unable to reach and maintain the set temperature on hot days, especially if it’s running continuously, the culprit may be an undersized AC unit.

Air ducts distribute cool air throughout your home. Holes or other types of damage to your ductwork can cause air leaks that impede proper airflow to all rooms within your home.

It’s best to contact a professional to seal duct leaks as it’s easy to make things worse and cause even more damage if you don’t know what you’re doing.

Homeowners insurance covers damage to appliances, including air-conditioning units, if they’re damaged as a result of a covered peril in your policy. A standard policy covers everything from built-in heating, ventilation, and air-conditioning (HVAC) systems to ductless and window AC units if they’re damaged by a fire or stolen from your property.

But if your HVAC unit stops working one day due to normal wear and tear after years of use, your insurance company likely won’t reimburse you for a new one.

Homeowners insurance covers AC units in the same way both the structure of your home and your personal belongings are protected. If the system is damaged by a covered loss, vandalized, or stolen, you’ll likely be reimbursed for repairs or the cost of a new one.

In other words, HVACs are covered against everything except hazards specifically listed in the policy, like earthquakes, flooding, power failure, and neglect.

Heating and air-conditioning systems can also cause extensive water damage to your home and personal belongings when pipes rupture due to freezing temperatures or if a drainage issue causes a leak.

If you file a water damage claim after an HVAC-related leak and the insurance adjuster determines the damage was caused by a clogged drain line that occurred over months or years of neglect, your claim may be denied.

But if the pipes connected to your air-conditioning system freeze and burst, causing damage to other parts of your home and your items, you may be covered for the damage caused by the AC, but you likely wouldn’t be reimbursed for a new system.

Homeowners insurance will not reimburse you for a new AC unit if it stopped working due to normal wear and tear, maintenance issues, or mechanical breakdown from improper installation or lack of quality. A standard policy also won’t cover damage caused by flooding.

Rodents and pests are also known to chew through HVAC electrical components and form nests in the ductwork, causing damage to the system itself and creating harmful air quality in your home.

Similar to wear and tear and flood damage, rodent and pest damage is also listed as an exclusion in homeowners insurance, so make sure that you’re sealing any potential points of entry for unwanted visitors.

Many homeowners insurance companies offer equipment breakdown coverage, a supplemental coverage for appliances that you can add to your policy for an additional $30 a year.

Equipment breakdown coverage essentially stretches your coverage for appliances like HVAC units, computers, and refrigerators to include things like mechanical and electrical breakdown and improper installation.

But keep in mind that home warranties are generally pretty expensive, costing around $900 per year. And you’re only covered for equipment specifically listed in your warranty. If you have equipment breakdown coverage through your insurer, all applicable property in your home is automatically covered.

The worst happens, your air conditioner shuts off and you’re stranded with an error code you can’t decipher. Depending on the brand and model of your air conditioner, a certain error code will usually be displayed and it could have either stopped completely or be stuck in “reduced capacity mode”.

Note: Different brands have different error codes. Turning off the isolator switch will cut the power from the switchboard and clear the memory of the air conditioning functions as it was doing beforehand.

Be mindful that if you try to turn your system back on at the hottest time of the day in 30 degree heat, it won’t cool as fast as it would if you turn it back on in the morning at lower weather temperatures. For more information on the best time of day to start your air conditioning click here.

At the time of your air con installation, we provide you with an instruction/user manual. Different brands have different tips to fix unwanted error codes, which you should be able to locate in your manual. It’s a good idea to have this handy if you need to call us. Sometimes these product manuals are also available online to download. Please be aware there are multiple product manuals so download the one specific to the model of your system.

It is estimated that there are around one billion personal computers around the world, and with every single desktop computer, there is also a monitor attached to it. Every day, hundreds of computer monitors break down, and if you have a LCD monitor that you bought fairly recently and have questioned why it won"t turn on anymore, it"s most likely a power problem that can be fixed to save you hundreds of dollars. This guide will specialize on the computer monitor model LG L196WTQ-BF, but most monitors will follow similar design and can generally be fixed using the same instructions.
