We have Cullerton Heating & Cooling come out 2x per year to do preventative maintenance. We typically have them check out the heat side in the early fall and the AC side in the spring.
It is recommended that an air conditioning unit be serviced every other year. This is done by checking the refrigerant levels, and cleaning the air filters. If your AC system is not serviced, it could cause your system to fail to operate efficiently. A dirty filter or clogged drain may cause your system to overheat.
