Top Causes of AC Failure

Jun 28, 2020 | AC, HVAC | 0 comments

Let’s face it: Life is complicated enough. And if you are like a lot of homeowners these days, you don’t give your air conditioner a lot of thought. However, when it’s hot outdoors, we do expect it to keep us nice and cool and cozy. At Kettering-Oakwood Heating & Air, we understand that A/Cs are often overlooked until they break down or need some kind of service. This is why we are forever here to help. After all, we depend on our air conditioners as well within our own houses. If you are having difficulties with your air conditioner, we put together a list of some of the more prevalent things that could be going on.

Common Reasons Why Air Conditioners Break Down

Absence of regular maintenance

Regular, routine maintenance is vital to your air conditioner’s lifespan, efficiency, and performance. Having a licensed technician visit your home will help recognize possible problems before they become greater problems. When completing annual maintenance, our technicians clean your air conditioning coils and examine your system. Neglecting to have your system maintained often voids any warranties from the A/C’s manufacturer. 

Coils Freeze Up

Dirty air filters (which need to be replaced regularly regardless) or clogged ductwork can produce airflow problems in your system, which can lead to frozen coils. Regularly cleaning or replacing your air filter and keeping your ductwork free and clear are two essential rules to follow to avoid getting a frozen coil.

Low Refrigerant Levels

Air conditioner refrigerant is dangerous. As such, any sort of leakage should be repaired and the refrigerant should be recharged by a licensed technician as soon as feasible. When your refrigerant levels are depleted, your air conditioner will not function properly.

Compressor damage, fan blade issues, and electrical connection issues

When an A/C compressor goes bad, it is usually the result of underlying issues that are placing stress on the system. These problems could include dirty coils, low refrigerant levels, electrical problems, fan blade issues, and more. As such, here is yet another reason why annual maintenance is so indispensable. Our technicians can recognize worn out and damaged parts before you find yourself in need of emergency repairs.

Defective circuit breaker or fuse

One of the first things that you need to check if your air conditioner fails is your circuit breaker or its fuse. Be sure to give it 10 to 15 minutes to let your air conditioner to cool. Then, replace the fuse or reset the breaker and find out if that’s the cause of the issue. If neither of these efforts fixes the problem, you could have tripped something known as a “high-pressure limit switch.” In such situations, we strongly urge homeowners to give us a call.

Faulty thermostat

If your home’s thermostat starts failing, your A/C usually cycles off and on frequently — if it at all. In these types of problems, it’s normally time to consider a thermostat upgrade. Having us install a smart or programmable thermostat will pay for itself in energy savings.
