Occasionally an air conditioner will break down with no warning. Typically, however, your Green Valley, AZ AC unit will send you signals that it’s having a problem. Here are four signs that will tell you an HVAC repair might be looming in your future.

AC Blowing Warm Air

An air conditioner blowing warm air frequently signals a problem with low refrigerant. If you’ve neglected maintenance, a dirty coil due to a clogged filter could be the culprit. Another possible cause of your AC blowing warm air is if you accidentally flipped your thermostat setting to heat mode rather than cooling mode.

High Humidity Levels

Condensation on your windows or a sticky, muggy feeling are two indicators that your air conditioner isn’t doing its job of dehumidifying your home. The AC repair might be simple (replacing your thermostat) or complicated (your system might be worn out and no longer capable of efficient dehumidification). Condensation could also be an alert for a broken or blocked condensation drainpipe.

Unusual Sounds

If you begin to hear sounds other than the comforting background hum of your AC running, that’s a clear alert that something is out of kilter. A high-pitched scream or whistle could indicate a refrigerant leak, blocked ducts, or a clogged filter. Banging and clanking could mean broken fan blades or motor, a detached part, or an unbalanced motor.

Odd Smells

Your AC unit should never smell. If it does, it’s time to call a service technician. A musty smell is a strong sign of bacterial lurking within your system. A burning smell suggests frayed or loose wiring or a problem with your fan belt.
