How Much Does a New Furnace Cost in Boston? [2025 Data]

New furnace costs in Boston, Massachusetts average $6,396, and most residents pay between $3,730 and $9,077. Your total will depend on the size of your home, which affects the necessary heating capacity of your equipment, the type of fuel you’re using, and the efficiency of the furnace. You may need to budget an additional $60 to $300 to remove and haul away your old furnace.

New Furnace Cost Factors

You could pay as little as $1,000 or as much as $25,000 to install a new furnace in Boston. There are a few factors at play that will determine where your total falls within that range.

Home Size

When you hire a furnace installer in Boston, they’ll start by assessing your heating needs, which depend largely on the size of your home. They’ll determine how many BTUs you need to heat your home sufficiently and maintain a comfortable and safe indoor temperature. Larger furnaces for bigger homes will drive up your material costs. The average home in Boston is 1,200 square feet and requires 60,000 to 72,000 BTUs, which is relatively high, due mostly to the long, cold winters.

The table below includes average sizes and prices for homes in Boston, but keep in mind that these don’t include installation labor. You should also always have a pro size your furnace for you. They’ll take other things into account, too, like general home efficiency, and they may recommend upsizing your system a bit for better performance and comfort.

Fuel Type

Half of all homes in Boston are fitted with gas furnaces, which are some of the most expensive types of furnaces to install, but they’re more efficient and more affordable to run than oil-fired furnaces. Just over 20% use oil as a heating source, and just under 20% use electric furnaces. The type you choose will affect your material and labor costs, with oil furnaces costing the most and electric furnaces costing the least.

Furnace Efficiency

Your material costs will also depend on the efficiency of the furnace you purchase. The annual fuel utilization efficiency (AFUE) measures the efficiency of your furnace. Furnaces with higher AFUE ratings will cost more upfront, but they can save you money on heating bills over time.

Furnaces with an AFUE rating of 90% or higher can be Energy Star-certified, which means they qualify for the 30% tax credit for Energy Star-rated furnaces offered by the federal government. Note that this is not a rebate, so availability depends on the income taxes you owe.

Old Furnace Removal

Unless you’re installing a furnace in new construction, you’ll need to pay to have the old furnace disconnected and hauled away. This will add $60 to $300 to your total.

If you’re switching fuel sources, you may see other fees added to your total. The cost to cap a gas line, for example, is between $125 and $250.

HVAC Pro Costs

Labor accounts for between $1,000 and $4,000 of your total when you install a new furnace in Boston. This is more than 50% higher than what you’d pay in most other areas due to the high cost of living in the city. Labor is expensive, but it’s not legal to DIY furnace replacement in Boston. Hiring an HVAC pro in Boston, Massachusetts, is always worthwhile to ensure a safe and legal installation, as well as a properly-sized furnace.

While your professional will pull the necessary permits for the work, you’ll also need to pay the associated permit fees. The City of Boston charges a $20 primary fee plus $0.09 per 1,000 BTUs. Given the average furnace size in the city, you’ll pay average permit fees of just $25.94.

Does a New Furnace Increase Home Value?

Installing a new furnace will increase your home value, as it gives buyers peace of mind that they won’t experience outages or expensive repairs for decades after they close. The average ROI for a new furnace is 30%, which means a home value bump of close to $2,000 in Boston. Since the winters are so cold and heating outages can be dangerous, going with a high-end, high-efficiency furnace can add even more to your property value.
