Most air conditioners need repairs now and then, and fortunately, there are signs you can look for to alert you to this. In the discussion that follows, we’ll describe a few of those signs and provide explanations of what they might indicate.
Unusually Loud Noises
It’s normal for an AC unit to make some noise when coming on or shutting off. Continual or unusually loud noises are another matter. Rattling and banging may be the result of a loose or out-of-balance part in the air handler. A defect in the relay or control could lead to an ongoing clicking noise.
Some noises can signify a serious issue. Hissing is often connected to refrigerant leaks while grinding sounds can be caused by the pistons in a worn-out compressor.
A musty smell from your AC vents denotes something specific: mold and mildew growth. It could be that your condensate drain line, which removes the condensation from the evaporator coil, has not been cleaned in a while. The condensation build-up will then invite bacteria.
Poor Indoor Air Quality
Another sign that you need repairs is a drop in indoor air quality. Perhaps someone’s allergies are acting up, or perhaps the air feels more humid (ACs do, to some extent, dehumidify). This can be due to dirty filters and vents. In addition, an AC that’s too big for your home will not remove humidity.
An AC should not short-cycle. This is when it turns on and off frequently before even reaching the set temperature. Have a technician from Anderson Heating & Cooling determine what’s causing the problem. The possibilities range from low refrigerant levels to a frozen evaporator coil.
If the air is blowing out lukewarm, you may have a problem with the outdoor unit. For instance, the condenser coil may be clogged and unable to remove the heat that’s being absorbed in the air handler.
