Serving Bel Air and Harford County

Before you call, check one thing

  • Make sure the outdoor unit isn’t covered or boxed in by furniture, bags or clippings. It has to pull in outside air.
  • Check that the thermostat is set to cool and the breaker hasn’t tripped.
  • Still not cooling? Call us. Running it low on refrigerant can damage the compressor.

Where we work

Bel Air, Forest Hill, Fallston, Abingdon, Churchville, Jarrettsville, Joppa, Edgewood, Aberdeen and Havre de Grace, plus the rest of Harford County and nearby parts of Baltimore and Cecil Counties.
