3 Signs You Need AC Repair

Is It Time to Repair Your AC?

1. It Makes Strange Noises

The only sound you should hear from your AC is its customary low hum. Anything that sounds unusual is an alert to contact your HVAC contractor. For example, a buzzing noise might indicate a problem with the fan motor in the outdoor unit, a dirty condenser coil, or a loose component. Rattling sounds might result from debris in the outdoor unit that can hinder the unit’s efficiency. A screech or scream is particularly serious, as it could indicate high pressure in the compressor. No matter what you hear, err on the safe side by promptly turning the unit off and contacting a professional.

Several issues could cause an AC to blow warm air. If replacing a clogged air filter doesn’t work, your contractor may check the evaporator coils to see if they’re frozen, or a refrigerant leak could also be to blame. This is never simply because the refrigerant is leaking, but because the coils responsible for circulating it are damaged in some way. Other signs that this is the problem include a hissing noise and a sudden spike in your energy bills.

3. It Has a Strong Smell

Don’t overlook an air conditioner that smells since it's usually due to a problem that requires professional assistance. For example, a buildup of mold and mildew in the ductwork due to excess humidity in your home could cause a musty odor. A dehumidifier can help prevent this after the mold is removed. A burning smell is indicative of a potentially overheated motor or damaged wiring, both of which are serious mechanical concerns that require prompt AC repairs.
