In most of the U.S., summer weather will cause homeowners to increase the use of the air conditioner. While simple things, such as changing the air filer and cleaning the vents can be done by homeowners, almost all of the components of the air conditioner should only be repaired or replaced by a service professional. Aire Serv explains why air conditioning components should only be inspected, serviced and replaced by trained technicians and how to keep systems running throughout summer.

Air conditioning components such as capacitors, contactors and control boards are integrated parts that allow compressors to operate properly. Components such as the compressor, which is the heart of the air conditioning unit, require skilled, trained technicians to work on them. Homeowners should never attempt to repair or replace the compressor or integrated parts.

“The refrigerant circuit is under high pressure and should only be accessed by a service professional,” said Kevin Bracht with Aire Serv. “An untrained person trying to repair HVAC components is at risk of causing personal injury or even death because of not following proper procedures recommended by the manufacture or trade practices.”

Another problem homeowners may run into is the lines of the air conditioner freezing. The most common causes of frozen air conditioning lines are from dirty filters or dirty evaporator coils. The system may also be low on refrigerant due to a leak.

“Always check the filter if you see the outside air conditioning lines are freezing up,” said Bracht. “If the filter is clean, a service professional should be contacted to test for leaks, circuit problems or a bad thermal expansion valve.”

Some general tips on keeping the air conditioning system running smoothly through the hot summer season would be to change filters on a regular basis, keep combustible materials or debris away from the indoor unit and keep high grass, hedges and fencing away from the outdoor unit to insure proper airflow.

“A lot of homeowners may not know pet urine can quickly degrade an outdoor unit and cause coil damage,” said Bracht. “Pets can and will chew on external wires at the condenser such as thermostat wires. Isolate or protect the outside unit from pets.”
