Southern Utah is a beautiful place to live, with its lovely deserts, mountains, and canyons. However, it can also be swelteringly hot. For this reason, your home must have a well-functioning air conditioning system to keep you and your family cool no matter the temperatures outside.

A broken down or malfunctioning air conditioning system is frustrating, but can usually be repaired by a qualified HVAC professional. Learn about five components of your air conditioning system that frequently need repair so that you’re prepared the next time something stops working the way it should.

Air Filters

Air filters protect your air conditioning system from dust and other debris in the air, and they have to be manually replaced to prevent system blockages. It’s generally recommended that a new air filter is installed every three months at least, but this may be much more frequent if you have pets, if your family members have asthma or allergies, or if you live in an environment that’s more dusty or polluted than usual. Fortunately, replacement air filters are relatively inexpensive and are easily installed by a non-professional.


Compressors are one of the most important (and expensive!) parts of an air conditioning system, responsible for compressing the refrigerant to cool down the air. Extended or intensive use can break down the compressor, and once that happens, your air conditioner won’t be able to function.

Evaporator Coils

Evaporator coils, also called the evaporator core, hold the refrigerant that takes the heat out of the air in your home. These coils need to be kept clean to function properly, and if they get dirty it can cause slowed or stopped performance. If the coils are too dirty, corroded, or frozen, they’ll have to be replaced.

Fan Motors

Fan motors are responsible for circulating cooled air throughout your home and blowing warmer air back outside. If you use your air conditioning system for long periods without a break, especially if it’s on high, it can cause the fan motor to burn out. Signs that your fan motor may need to be repaired or replaced include non-functioning cooling fans, blades that only rotate very slowly, a rattling noise, and a burning smell.


Lastly, don’t forget about the thermostat itself. Though not a direct component of your air conditioning unit, a malfunctioning thermostat is a major issue as it prevents your air conditioning system from functioning properly. If your air conditioner isn’t reaching the right temperatures, is turning on and off, or isn’t working at all, don’t forget to check your thermostat for issues.
