Boston Weather and HVAC Load
NOAA's 1991-2020 climate normals put Boston at 5,545 heating degree days and 801 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Boston put in far more hours than the air conditioner. A normal year brings 92 nights at or below freezing and 14 days over 90°F. Snowfall averages about 49 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 5,545 |
|---|---|
| Cooling degree days / year | 801 |
| Nights at or below 32°F | 92 |
| Days above 90°F | 14 |
| Average low / high | 44.5°F / 59.3°F |
Boston Housing Stock
The median Boston home dates to 1947, according to the Census ACS. That makes the typical house about 79 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Boston has roughly 99,000 owner-occupied homes, or 35.4% of households. The median home value is $710,400, and median household income is $94,755. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 2 hail days and 15 days with damaging thunderstorm winds in Suffolk County. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.
When It Makes Sense
- The house heats with electric baseboard, oil or propane
- Your AC needs replacing, and you'd like cheaper heat at the same time
- There's no natural gas service on your street
What Moves the Price
- Size in tons, and whether the unit is cold-climate rated
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- A ducted system or a ductless mini-split
- Variable-speed (inverter) or single-stage compressor
- Electrical panel capacity and wiring
For Boston we raised the national figures about 43%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- The outdoor heat pump and an indoor air handler or coil
- Commissioning and warranty registration
- Line set, drain and electrical hookups
- A load calculation and equipment selection
- Thermostat setup and backup heat settings
Massachusetts Permits, Efficiency Rules and Rebates
Massachusetts falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Plan on a mechanical permit for most replacements in Boston; the contractor normally pulls it. Before you sign, ask each bidder for their Massachusetts license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Make sure the installer sized the system for your heating load, not only cooling.
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- Ask your electric utility and state energy office what heat pump rebates are open right now.

Heat Pump Installation Questions from Boston Homeowners
How much is heat pump installation in Boston?
Plan on $7,900 to $19,300, with most jobs near $14,200. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Boston?
Between late spring and early fall. Boston averages 92 freezing nights a year, and heating calls spike from November through February.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
