HVAC Services in Flagstaff, AZ
NOAA's 1991-2020 climate normals put Flagstaff at 6,745 heating degree days and 144 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Flagstaff put in far more hours than the air conditioner. A normal year brings 202 nights at or below freezing and 3 days over 90°F. Snowfall averages about 90 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 70,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
