Signs Your AC Needs a Repair (Before It Breaks Down Completely)
Warm Air Coming From Vents
If your system’s running but the air isn’t cold, there could be a refrigerant issue or compressor problem.
AC Keeps Cycling On and Off
Frequent starts and stops? That’s a sign something’s off with your system’s operation.
Higher Energy Bills With No Change in Usage
If your power bill’s climbing but your habits haven’t changed, your AC may be working harder than it should.
Unusual Noises or Leaks
Buzzing, rattling, or water pooling near the unit means it’s time for a professional look.
