Knowing When It Is Time for AC Tune-Ups

Air conditioning tune-ups come with a myriad of benefits, and everyone with an AC system, be it a central unit, heat pump, or mini-split, is encouraged to get a tune-up at least every spring. The following are just a few signs, which homeowners themselves can look out for, that the time has come for a tune-up.

A Rise in Electricity Bills

Unusually high utility bills are perhaps the main warning sign, and these can have a variety of causes. For example, dirty filters and clogged vents may be forcing the AC system to work harder. A leak in the vents could also be responsible.

Short-Cycling and Less-Than-Stellar Performance

Homeowners may want to ask themselves if it seems like their AC is taking longer than before to meet the temperature on the thermostat. This could be the result of a failing fan motor. If the AC is short-cycling (constantly turning on and off), it could signify low refrigerant levels or dirty evaporator coils. Uneven cooling is another issue that could spell the need for a tune-up.

Strange Noises and Unpleasant Odors

There are some noises the AC should not make. A banging noise suggests a loose or broken component, especially a broken compressor. A buzzing noise may point to an electrical problem like loose wiring or a bad motor. Failing motors and compressors may also make a screeching sound.

Homeowners do not want to smell a musty odor because this means there is mold or mildew in the vents. Mold can cause health problems, starting with chronic coughing, throat irritation, fatigue, and headaches. One might think that removing mold is a simple DIY project, especially with a mini-split, but the fungus is always liable to grow again without professional help.
