Heating & cooling

Heating and cooling a home in Clearwater

48% of the work is heating, so air conditioning is the bigger bill. Months averaging under 55° run from November through February.

2,182 heating degree daysLess heating than 86% of U.S. towns
2,361 cooling degree daysMore cooling than 87% of U.S. towns

Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Augusta Bush Fld Airport.
