District of Columbia: HVAC Replacement Cost Calculator

Replacing an HVAC system in the District of Columbia typically runs $7,500 to $13,000 installed for a matched central AC and gas furnace, while a standalone heat pump lands between $6,000 and $12,000. DC labor costs sit about 31% above the national baseline, with HVAC technicians earning an average of $40.83 per hour, so installation labor is a bigger share of your bill here than in most of the country.

Worked example

A 1,600-square-foot Capitol Hill rowhouse with a 20-year-old furnace and a failing condenser needs both pieces replaced at once. Because the existing ductwork is usable and the equipment sits in a tight basement mechanical closet rather than requiring crane or roof access, the job lands mid-range for the District — roughly $10,000 to $11,000 within the $7,500 to $13,000 AC-plus-furnace band. Adding a high-efficiency variable-speed furnace or reworking undersized return ducts would push it toward the $13,000 top end.

Frequently asked questions

How much does a heat pump cost in Washington, DC?

Heat pump replacement in the District runs $6,000 to $12,000 installed. The low end reflects a straightforward swap of a single-stage unit onto existing ducts; the high end covers larger, higher-efficiency variable-speed systems or jobs that need electrical upgrades and duct modifications.

Why is HVAC installation more expensive in DC than elsewhere?

The District carries a labor index of 1.31, meaning installation labor costs about 31% more than the national baseline, and local HVAC technicians average $40.83 per hour. Tight urban job sites — rowhouses, alley access, and cramped basements or closets — also add hours to a typical install.

Is a heat pump a good fit for DC's climate?

The District sits in climate zone 4, a mixed climate where heat pumps handle the bulk of the heating season efficiently. At $6,000 to $12,000 installed, a heat pump often costs less than a $7,500 to $13,000 AC-plus-furnace pairing because you are buying one piece of equipment instead of two.

What does it cost to add cooling to a DC rowhouse with no ductwork?

Ductless mini-splits run $3,500 to $10,000 in the District, depending on how many indoor heads you need. A single-zone system for one converted attic or addition sits near the low end, while a three- or four-zone setup covering a full rowhouse approaches $10,000.
