San Francisco Weather and HVAC Load
In a normal year, San Francisco racks up 3,260 heating and 29 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in San Francisco put in far more hours than the air conditioner. Temperatures stay mild year-round: freezing nights and 90°F days are both rare.

San Francisco Housing Stock
Census figures put the median build year in San Francisco at 1945, so a typical house here has about 81 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. About 140,000 households here own their home, 38.5% of the occupied total. Homes here have a median value of $1,380,500 and households a median income of $141,446. Those two numbers drive the labor adjustment in our estimate.
San Francisco County had 3 hail days and 4 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.
