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

New furnace costs in Washington, D.C., average $5,581, and most installations in the area total between $3,743 and $7,475. The size of your home and the fuel type you have available for heating will affect your costs more than any other factors, but the furnace efficiency you choose can play an important role, too.

New Furnace Cost Factors

A new furnace in Washington, D.C., could cost as little as $1,472 or as much as $11,000. The following factors will determine where your total falls within that wide range.

Home Size

Furnace installers in Washington, D.C., will size your furnace based on your heating needs, and the BTU rating is the biggest factor in terms of cost. Homes in Washington, D.C., need between 45 and 50 BTUs per square foot. The average home in the city is 1,350 square feet and needs between 60,000 and 67,500 BTUs. Larger homes and those with poor insulation and low overall energy efficiency will need larger furnaces that drive up material costs.

The table below includes average material costs based on home square footage, but it’s important to have a professional size your system for you, as there are many other factors that affect ideal furnace size.

Fuel Type

Close to half of all homeowners in Washington, D.C., use natural gas to heat their homes, but your total can vary if you use a different fuel source. Electric furnaces are the most affordable types of furnaces but cost the most to run. Oil furnaces are the most expensive to install but provide the most heat, which makes them a popular option for weathering the long, cold winters in D.C. Gas furnaces fall somewhere in the middle in terms of cost, and they’re more efficient than oil furnaces.

Efficiency

The efficiency rating of the furnace you choose will also affect your material costs. The annual fuel utilization efficiency (AFUE) measures furnace efficiency. The higher the rating, the more expensive the equipment will be, but the less fuel it will use to provide heat and the lower your ongoing heating costs will be.

The winter temperatures in Washington, D.C., dip below freezing for five months out of the year, so paying for a high AFUE is worth it in the long run. Choosing a furnace with an AFUE rating of over 90% makes you eligible to take the 30% energy efficiency tax credit from the federal government, which can significantly bring down costs if you owe enough in taxes to take full advantage.

Old Furnace Removal

Having your HVAC pro remove your old furnace and haul it away will add between $60 and $350 to your total. Some professionals include this in their labor fees, so ask your HVAC tech before budgeting separately.

Most homeowners keep their existing fuel type, but if you’re converting from gas or oil to a more eco-friendly electric furnace, you’ll also need to pay $125 to $250 to cap the old gas line or between $580 and $2,100 to remove an oil tank.

HVAC Pro Costs

On average, the labor to install your new furnace in Washington, D.C., will cost between $1,000 and $4,000. While this is a steep price to pay, replacing a furnace yourself isn’t legal in the city, and it’s also not safe. Hiring an HVAC pro in Washington, D.C., is well worth the investment and will help ensure a properly sized furnace that functions well for many years to come.

You’ll also need to account for permit fees for your furnace replacement. Washington, D.C., charges a flat rate for this project, totaling $52. This may be included in your initial estimate, but if not, make sure to budget separately. Your HVAC professional will handle all of the paperwork, so you’ll just be responsible for the fee.

Does a New Furnace Increase Home Value?

Installing a new furnace will make your home more desirable to buyers, so your home value will increase. Especially in an area with long, frigid winters, like Washington, D.C., furnaces see a lot of wear and tear, and buyers will often pay more for the peace of mind that they won’t need to lay out additional money after closing to repair or replace the furnace.

A new furnace provides an average ROI of 30%, which means a home value increase of close to $1,700 in Washington, D.C. Investing in a high-efficiency furnace that will keep operating costs low through the freezing winters could boost home value even more.
