Air conditioning systems are complex machines with numerous interconnected parts. When something goes wrong and your system isn’t functioning like it used to, it’s always best to call in the pros. While some problems—such as an AC that just won’t turn on—are obvious, others can be harder to spot.

If you notice any of the following issues, it’s probably time to schedule a professional AC inspection and repair service:

  • Warm air blowing from the indoor unit
  • Uneven cooling throughout your home
  • Poor or nonexistent airflow
  • Unusual noises, such as creaking or banging, coming from the unit
  • Unpleasant odors emitting from the AC
  • Frequent “cycling” (turning on and off)
  • Indoor air temperature doesn’t seem to match thermostat setting
  • Very high or very low indoor humidity levels
  • Decreased efficiency, often evident in the form of higher-than-normal utility bills

Some AC issues are as easy to resolve as simply cleaning the filter or re-calibrating the thermostat, but others require extensive repairs and may even necessitate fully system replacement. It’s always a good idea to have a professional take a look at your system and determine the best course of action.
