Why Won’t My Air Conditioner Turn On?

When your air conditioner refuses to turn on, the comfort of your home or business can be significantly impacted. The cause of this problem can range from simple to complex and may include issues with your thermostat, the shutoff switch, a clogged condensate drain, a tripped circuit breaker or blown fuse, amongst a host of other possibles reasons. In order to determine the specific cause behind this issue, it’s best to contact a trained air conditioning repair professional who can inspect the unit, handling whatever repair is needed safely and efficiently. 

An AC unit refusing to turn on is a major indicator that service is required, however, there are other potential signs that you should watch for that could also point to repair being needed. 

HOW DO I KNOW IF MY AC NEEDS REPAIR?


  • Your air conditioner starts blowing out warm air instead of cool air
  • Your property feels more humid than normal 
  • Your system is leaking water
  • Your air conditioner is making unusual screeching, whistling, or banging noises
  • Your system is no longer producing the same level of airflow
  • Your thermostat isn’t communicating with your air conditioning unit
  • Your energy bills have increased more than usual
  • Your air conditioner smells musty or like it’s burning when running
  • Your indoor air quality has decreased

If you have noticed any of the above signs, don’t hesitate to contact the Lake Forest AC repair pros at John Stevenson Plumbing, Heating & Air Conditioning, Inc..
