What District of Columbia Residents Should Know
District of Columbia falls in IECC climate zone 4A with 4,200 heating degree days per year — below the national average. Modern cold-climate heat pumps achieve an average COP of 2.8 in District of Columbia's conditions, making them competitive with gas furnaces for most of the heating season.
With natural gas at $1.50 per therm in District of Columbia, 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.
While District of Columbia does not currently offer state-level heat pump incentives, the federal 25C energy efficient home improvement tax credit covers up to $2,000 for qualifying heat pump systems. This credit, combined with long-term energy savings and the dual heating-cooling functionality, makes heat pumps an investment worth evaluating for most homeowners.
