My Lexington Cooling System Won’t Turn On!

Heating & Cooling


It’ll probably happen at some point during your experience as a homeowner – you’ll go to turn your air conditioner on, only to be met with nothing. Believe it or not, this is a common problem – one of the most frequent we solve. If it happens to you, here’s what you should do.

Troubleshooting Your Air Conditioner

Sometimes, a lack of power is all that is standing in the way of cooling. Switches can be flipped accidentally, breakers tripped without your knowledge. If your air conditioner won’t turn on, check all power sources related to the system.

  • On/off switch near the outdoor condenser
  • On/off switch at the furnace/air handling unit indoors
  • Electrical panel breakers
  • Thermostat

Make sure you have your thermostat set correctly, or the cooling system won’t turn on. It should be set to cooling mode, with the temperature setting adjusted down about 3 degrees below what the current temperature is indoors.

Fixes for Your HVAC Contractor

If troubleshooting doesn’t work, call Climate Control for quick air conditioner repair service. Wiring or electrical connections within the system may have loosened, triggering safety controls. If components have iced over or overheated, that may also cause the air conditioner not to start when you turn it on.

Sometimes, it’s a thermostat issue. Your current thermostat may require recalibration to perform correct temperature readings. Or, it may require replacement. Upgrading to a programmable model from a manual thermostat is smart anyhow, as when used correctly, it can help you regain control of both your comfort and household energy consumption.

Don’t let a Lexington air conditioner that won’t start stand in the way of your comfort this summer. Climate Control will dispatch NATE-certified technicians right away to get to the bottom of your cooling issues and provide trustworthy repairs to help your cooling system power through the hot summer temps.
