How Much Does a Heat Pump Cost in Washington, D.C.? [2025 Data]

The average heat pump cost in Washington, D.C., is $5,896, but it’s common to spend between $4,477 and $7,349 on this project. Prices vary based on the type and size of the heat pump, as well as the cost of professional labor. Here’s how the specifics of your job affect your heat pump installation costs in Washington, D.C.

Heat Pump Cost Factors for Washington, D.C.

Whether you’re installing a heat pump to fend off the summer heat and humidity or stay toasty through winter (or both), here’s a breakdown of what it will cost you.

Type of Heat Pump

In the early phases of your project, you’ll need to choose the right kind of heat pump for your Washington, D.C., home—and the type you pick will have a direct effect on your costs.

Air-source heat pumps (including the popular ductless mini-split heat pumps) are more affordable, while ground-source (also known as geothermal) heat pumps are pricier.

Heat Pump Size

The size of your heat pump makes a difference in your costs, too. Manufacturers list heat pump sizes in tons, British Thermal Units (BTUs), or both—and either way, a higher number equates to more heating and cooling capacity (and a higher price tag).

Here are some common air-source heat pump sizes (in tons and BTUs), along with their average unit costs (not including installation):

Efficiency Rating

Heat pumps have two efficiency ratings: Seasonal Energy Efficiency Ratio (SEER) for cooling and Heating Seasonal Performance Factor (HSPF) for heating. These systems measure how efficiently the unit cools or heats your home—and like heat pump sizes, higher numbers translate to better efficiency and more expensive unit costs. 

In this table, you can see how heat pump costs increase as their SEER ratings go up:

Heads up: In the U.S., there are minimum standards for HVAC efficiency that vary by region. For example, a new split-system heat pump in Washington, D.C., must have a SEER rating of 15 or higher and an HSPF rating of at least 7.5.

Ductwork Installation or Replacement

Unless you buy a ductless heat pump, you’ll need ductwork to push warm or cool air from your heat pump into your house. If you don’t currently have a duct system, you can install one for $3,000 to $7,500 per 300 linear feet.

Even if your home already has ductwork, there are situations where you’ll need to replace it before installing a new heat pump. For instance, if your existing ductwork is damaged or incompatible with your new HVAC system, you’ll need an upgrade. On average, ductwork replacement costs $419 to $1,278 in Washington, D.C.

HVAC Pro Costs in Washington, D.C.

In this project, there are a few other expenses that will bump up your budget, including permit fees and the cost of hiring a local heat pump repair pro. 

Licensing and Certification

When you hire a heat pump installer in Washington, D.C., make sure they’re licensed by the District of Columbia Board of Industrial Trades. Also, your contractor must be certified by the Environmental Protection Agency (EPA) to handle refrigerants.

To find the most qualified HVAC professionals in D.C., look for those with North American Technician Excellence (NATE) certifications. If a pro has this voluntary certification, it means they have at least several years’ worth of HVAC experience and have passed exams to prove their knowledge.

Permits

In Washington, D.C., installing and replacing HVAC equipment requires a mechanical permit from the Department of Buildings (DOB). Your installer should obtain this permit before any work begins—otherwise, you could receive a fine.

Rebates

If you switch from a gas furnace to a heat pump or upgrade to a more efficient heat pump, you could get a rebate from the DC Sustainable Energy Utility (DCSEU). Rebates vary from $1,000 to $1,500, depending on the heat pump’s efficiency level.

Does Installing a Heat Pump Increase Home Value in Washington, D.C.?

Since a heat pump provides cooling and heating, it can be a big draw for homebuyers in Washington, D.C., especially if it’s a high-efficiency model. It offers people the peace of mind that their new home will stay comfortable all year long—even through D.C.’s heatwaves and snowstorms. 

Plus, having a brand-new unit gives buyers the confidence that they won’t have to replace their HVAC system for a decade or more. After investing in this type of upgrade, you could see a 5% to 7% hike in your home’s value.
