Hayward HVAC – 3 Reasons Your AC May Overheat & Shut Off

Temperatures are warming up, which means Bay Area homeowners will soon be using their A/C systems. Nothing is worse than coming home and finding that the inside of your home is hot and humid, when all you want is cool, comfortable air. Why did your A/C overheat and shut down? Here are three of the most common reasons.

Condenser coils are dirty. Condenser coils are located in the outside unit of your system, and are filled with refrigerant. Your air conditioner will run longer if the coils are dirty, which results in overheating. Dirt prevents the coils from releasing the heat absorbed from the air inside your home to the outdoors, which means the coils cannot absorb additional heat from the indoor air – the dirt acts as an insulator of sorts. Clean the coils using a solution designed for this purpose, or call our Hayward HVAC professionals.

Dirty air filter. Although we’ve stressed the importance of changing the air filter regularly, some homeowners still don’t do it. A dirty air filter forces your cooling system to run longer and work harder, because it blocks the airflow in the air ducts of your home. This will result in your A/C breaking down, or overheating which will trip the circuit breaker. To remedy the problem, change the air filter every month. The solution really is that easy!

Low refrigerant level. If your home isn’t cooling down as quickly as it once did, the outside of your unit is frosted or covered with ice, or your A/C doesn’t seem to be able to do the job on days that are hotter than usual, it could be low refrigerant is to blame. The problem here is that if refrigerant is low, you also have a leak. Refrigerant circulates through the coils, but it isn’t “consumed.” Call our air conditioning repair experts to solve the problem.
