Common AC  Problems (Part 2 of 2)

Below we explain several common AC problems (Part 2 of 2) to help you understand what may be happening, if your AC is not functioning properly.

Damaged Thermostat

“Honey, did you check the batteries in the thermostat?” This is perhaps one of the best questions to ask before going any further! Many homeowners are relieved to discover what they initially believed to be a malfunctioning air conditioner, is only a thermostat that needs a replacement battery. If you have a thermostat that runs on batteries, ( not all run strictly on batteries) do yourself a favor and replace them once a year.

If your thermostat is located in an especially sunny area of your home, it may not be clearly communicating with your AC unit. As a result, it  detects incorrect temperatures, causing the system to run continuously.  If this is the case, you may need to have the thermostat relocated. To be certain, call Sunset Air for an in-house inspection.

Keep in mind, malfunctions do happen. Perhaps the circuit breaker tripped, the water overflow safety switch was triggered, a loose connection occurred, or the thermostat has reached its life expectancy. While a thermostat may look easy enough to self-diagnose, it is a significant piece of electrical equipment that can cause harm and damage if not handled correctly.

Outdoor AC Fan Not Working

Take a walk outside to your condenser unit. Look at the fan through the vents. Is it spinning?

Dirty Evaporator Coil

If you’re not feeling enough cool air being delivered into your home, the problem may be a dirty evaporator coil.  Dust and other airborne particles often accumulate in the evaporator coil of the air conditioner resulting in restricted air flow.  Frequently, this is the result of an air filter that needs to be replaced.

Dirty Condenser Unit

If your system seems to be cycling on and off excessively, check the outdoor condenser unit for any obstructions. You may be surprised to find tall weeds or overgrown bushes, which could be causing an issue.  Your condenser needs room to breathe for proper air flow across the coils and compressor.  Therefore, be sure to give it the space it needs to continue running efficiently.
