Signs You May Need an AC Diagnosis 

Numerous issues could cause problems with your AC, from hiccups with the compressor to other malfunctioning parts. Knowing what to look for will preserve the health and comfort of you and your loved ones.

  • Frequent on/off cycling: Air conditioners usually complete two to three cooling cycles on the hour, with each cycle averaging a minimum of 10 minutes. If your AC stops short of that, you may want to enlist the eyes of a pro.
  • Uneven cooling:  It’s not acceptable when rooms don’t cool to your satisfaction. If you’re experiencing uneven cooling levels, your AC may benefit from a comprehensive diagnosis.
  • Increased energy bills: This could indicate a unit working harder than it needs to. If utility bills surge unexpectedly, one or more AC parts could be running inefficiently, or even damaged and need repair.
