Top Reasons Behind What Causes a Sudden AC Failure

November 23rd, 2021

Island life is an absolute dream for those living in the continental United States. However, as most Hawaiians attest, this dream can quickly become a sweaty nightmare when your AC is not working. If your HVAC system experiences a sudden power failure, you may think the worst has occurred. You may even fear you will need to purchase a new system.

However, in reality, an AC tech can quickly resolve most power failures. So the next time that your AC suddenly stops working, consider the following possible causes behind the power failure and remember that the technicians at Island Comfort Air Conditioning are here to resolve your problems and restore functioning as soon as possible.

Frozen Coils

The coils within your AC are responsible for transporting the hot air outward but hinder the airflow if they become dirty from built-up debris. As a result, the coils can freeze, which can lead to a sudden power failure. To stop your coils from freezing over time, clean them regularly.

Damage in the Internal Components

Damage to the internal components of your HVAC system can lead to premature failure of your home’s AC. In particular, older models are more likely to experience this type of failure, but only due to a lack of maintenance. By replacing damaged compressors, fan blades, and electrical connections and contacts, you will be able to avoid any severe damage and shutdowns as well as prolong the life of your AC.

Broken Thermostat

If your AC fails to work because of a faulty thermostat, repairs are usually quick and effective. However, when your thermostat is damaged, your HVAC system will usually cycle on and off without stopping, which can lead to the system failing by overworking itself. 

The key is to catch the malfunction before any significant damages occur. You should immediately contact your maintenance team when you notice that your thermostat isn’t working correctly. Luckily, there are many thermostat replacement options today that offer an array of different features, such as room-by-room control options and WiFi connectivity.

Leaking Refrigerant

Anytime that the refrigerant levels within your HVAC system are low, there will be problems with functioning. Leakage can result from many reasons but is most often caused by an aging AC. When your AC has been running for over ten years, the components that hold the freon in the refrigerant can become damaged and result in leaks and system failure. This is typically a more severe issue, as the only practical solution is investing in a new HVAC system.

Lack of Annual Maintenance

Ultimately, it’s best to keep in mind that routine maintenance can help avoid all of these reasons behind AC failures. Schedule servicing for your HVAC system at least once a year to ensure that it is in working order. During servicing, your certified technician will be able to spot any potential damage or errors that could result in a system failure in the future. Furthermore, remember to leave all AC repairing to the professionals, as DIY attempts could result in additional problems.

Is Your AC Repeatedly Turning On and Off? Here We Explain Why!

November 2nd, 2021

Though you may choose to ignore it at first, your air conditioner’s constant on and off cycling can indicate a severe problem. Of course, this is not always the case, but it is usually wise to go ahead and call your servicing company and ask for a technician to come and do the necessary AC repairs.

If your AC is not working as it should, do not panic! Island Comfort’s techs can quickly conduct AC repairs at a relatively inexpensive cost. However, you should not delay contacting a professional. Otherwise, the on and off cycling you notice can lead to additional problems and system malfunctions. Such malfunctions typically result from your air conditioner overworking itself. 

We strive to provide our customers with the best products, services, and advice pertaining to their HVAC systems. Here is are the most common reasons that your AC is short cycling, as well as possible methods of prevention. 

What Is Short Cycling?

The term “short cycling” describes a situation in which your HVAC system is turning on and off before completing an entire cycle, which is the point when the unit stops after reaching the desired temperature. There are several reasons for short cycling, and luckily, routine maintenance can help avoid most malfunctions.

Electrical Malfunctions

The most common electrical issue that causes your AC to cycle on and off is a malfunction with the thermostat. Your thermostat is the control center for your entire HVAC system. So, when the connections, in which the electrical signals travel, become damaged your AC will shut on and off before completing its entire cycle. 

Other malfunctions include issues with circuit boards, the compressor, and run capacitors. However, each type of electrical malfunction can ultimately result in a damaged HVAC system as the system overworks itself to balance the temperature.

Oversized HVAC Unit

Sometimes, an AC is too large for your home. In this instance, as the AC cools the smaller space at an excessive rate, the desired temperature is achieved too quickly, and thus the unit turns on and off more frequently. While this may not seem all that bad, internal components can become damaged over time due to being overworked.

Prevention Methods

Ultimately, short cycling that continues for long periods can lead to increased utility bills and damaged equipment. The only guaranteed way to avoid this phenomenon is to commit to routine maintenance checks. When you schedule annual servicing appointments for your AC, a technician will check for all of the causes listed above that may lead to short cycling and run additional checks to ensure that all is working as it should. 

As a result, you can rest assured that your AC will continue working effectively and efficiently for the years to come.

6 Common Reasons Why Your AC Is Not Turning On

September 28th, 2021

You’ve invested in an air conditioner, so it’s only right that you get what you’ve paid for. It can be extremely frustrating to have a dysfunctional AC, let alone one that refuses to turn on. But don’t worry! There are many common reasons that an air conditioner won’t turn, and many of these problems have simple solutions. 

ac tech

With the help of our team, we’ve compiled a listing of all the reasons for why your AC may not be turning on, as well as both standard and complex solutions to your problem.

1) Clogged Air Filter

Changing your air filters is extremely important when it comes to the proper operation of your AC unit. Clean air filters ensure proper airflow. When dirt, dander, hair, dust, or other materials accumulate, the airflow becomes restricted. When your air filters are dirty, the humidity that’s normally absorbed from your home freezes and covers the coils with layers of ice. This can cause a need for immediate AC repairs. The best way to avoid this issue is changing your air filters regularly and cleaning your home frequently. 

2) Tripped Circuit Breaker

Circuit breakers were designed to shut off when they receive or detect an electricity overload. Breakers often trip when too many appliances are used at once or when a single appliance is old and uses too much electricity. When the circuit breaker trips, your AC won’t turn on. The best way to avoid this is to be conservative in your electricity and appliance usage.

3) Dysfunctional Thermostat

The thermostat for your unit serves as the control panel and acts as the most integral part of your system. If your thermostat is outdated, blank, broken, or needs batteries, it can prevent your AC from turning on. Some of these problems have simple solutions like replacing batteries or running a diagnostic test. However, in some instances, your thermostat may need to be replaced.

4) Faulty Motor

If you’ve experienced strange noises coming from your AC before it turned off completely, the issue may be a faulty motor. Capacitor tests are great at determining whether or not your motor still has some life in it. However, these tests are best left to those that are qualified in air conditioner repairs.

5) Dirty Condenser Lines

Another reason why your AC isn’t working may be due to dirty condenser lines, which get dirty the same way that air filters do. Condenser lines can be cleaned by locating your condenser unit outside of your home, lifting the lid, and using a wet or dry vac to get rid of the debris inside. Make sure to turn off the power source that feeds electricity into your AC before doing this. If this sounds too dangerous or complicated for you, contact a professional

6) Dirty Evaporator Coils

The same dirt, dust, dander, and hair can build up on your evaporator coils just as they come together in your filters or your condenser lines. Your AC is full of components that are likely to accumulate debris. This build-up can be the reason why your unit won’t turn on. You should schedule regular AC maintenance to ensure that your air conditioner is operating at its full capacity.
