The city lists $500 per household for heat pumps that keep gas backup or replace electric heat, and $2,000 when the gas heater is removed. Equipment must be AHRI certified at 16 SEER2 and 8 HSPF2 or better. Confirm current terms with the city.
Cooling is usually the larger load in Healdsburg. HAXX runs a room-by-room load calculation instead of copying the old unit's size.
