Is Something Wrong with My AC?

It’s easy to take your air conditioner for granted—until something goes wrong. Some issues are obvious, like warm air blowing from the vents, while others sneak up over time, gradually reducing efficiency and comfort. 

If you’re noticing any of the following signs, it might be time to have a professional take a look:

  • Warm air coming from the vents
  • Weak or inconsistent airflow
  • Unusual noises like banging, rattling, or buzzing
  • Unpleasant odors when the AC is running
  • Frequent cycling on and off
  • Higher-than-normal energy bills
  • Uneven cooling throughout the home
  • Excess humidity or moisture buildup
  • Ice forming on the outdoor unit or refrigerant lines

Ignoring these warning signs can lead to bigger problems down the road. If something seems off, we’ll pinpoint the issue and get your AC back to running the way it should.
