Heat Pump Savings Calculator in California

Compare heat pump and furnace heating costs in California. Uses local climate data (2400 HDD), electricity rates, and fuel prices for accurate savings estimates.

What California Residents Should Know

California falls in IECC climate zone 3B with 2,400 heating degree days per year — well below the national average. With an average heating COP of 3.3, heat pumps in California operate at high efficiency, producing 3.3 units of heat for every unit of electricity consumed.

With natural gas at $1.80 per therm in California, a gas furnace may have lower operating costs in the coldest months. However, heat pumps provide both heating and cooling in one system, which can offset the difference when you factor in AC savings. In shoulder seasons (spring and fall), a heat pump is significantly more efficient, often making the overall annual cost competitive with gas.

California residents can access up to $3000 in state rebates and incentives for heat pump installations, in addition to the federal 25C energy efficient home improvement credit. These incentives can significantly reduce the upfront installation cost, which typically ranges from $4,000 to $8,000 depending on system size and complexity.
