Our estimate for this home
A high-efficiency cold-climate heat pump comes out ahead
A high-efficiency cold-climate heat pump comes out ahead here even with a high quote: about $17,400 less than a new furnace and AC over 15 years at typical prices, and $900 a year less to run.

What this is based on
- Electricity: City of Chicopee's average residential price in MA (EIA), $0.162/kWh; the winter price of extra kWh is estimated at $0.154/kWh. Enter your own rate for a closer answer.
- Weather: Westfield Barnes MUNI AP (6,330 heating and 677 cooling degree days a year, 1991-2020).
- Gas: Massachusetts average residential price over the last five winter months (EIA), $2.46/therm.
- Massachusetts HVAC installer wages are 27% above the U.S. median (BLS), so installed prices are scaled by 1.13.
- Energy use for heating and cooling:
- New gas furnace + new AC: 1,450 kWh and 604 therms a year for heating and cooling
- Heat pump (replaces both): 7,009 kWh a year for heating and cooling
- High-efficiency cold-climate heat pump: 5,242 kWh a year for heating and cooling

ENERGY STAR Cold Climate equipment, Mass Save installer network. Gas-heated homes qualify through a Mass Save gas sponsor (Berkshire Gas, Eversource, Liberty, National Grid, Unitil); municipal gas customers do not. Whole-home requires the home to be sufficiently weatherized. - Municipal light plant customers may have their own town rebates on top. The federal 25C tax credit ended with 2025 installs. Mass Save also offers a 0% HEAT Loan.
How City of Chicopee's rates change the answer
City of Chicopee's electricity price for a typical home is 47% below the Massachusetts average ($0.162 vs. $0.303 per kWh). A heat pump moves your heating from gas to electricity, so the electricity price is the biggest single factor: calculators that use a state average can get the answer wrong for your utility. At these prices, a heat pump is cheaper to run for a typical home here.
How we calculate this
Heating and cooling need
Your home's yearly heating and cooling need comes from 1991-2020 NOAA climate normals for the nearest weather station, scaled by floor area and insulation level. If you know last winter's gas use, compare it with the therms in the energy-use list above.
Equipment efficiency
New furnace 95% AFUE; new AC SEER2 13.4; standard heat pump SEER2 15.2 / HSPF2 7.8; high-efficiency cold-climate heat pump SEER2 21.5 / HSPF2 10.6. Heat pump efficiency falls as it gets colder, and in cold months part of the heat comes from backup electric strips (or your old furnace, if you keep it). Existing equipment is assumed to be a 15-20 year old 80% furnace or SEER2 9.5 AC.
Installed costs
Installed prices vary a lot, so we show a typical price and a range for a home of about 1,800 sq ft with existing ductwork, scaled for larger or smaller homes: furnace and AC together $9,000–$14,000; furnace alone $3,800–$7,000; AC alone $4,500–$9,000; standard heat pump $8,000–$15,000; high-efficiency cold-climate heat pump $11,000–$20,000; electrical panel upgrade, if needed, $1,500–$4,000. These are national figures drawn from published studies and program data (NESCAUM / Energy Solutions, Heat Pumps in the Northeast and Mid-Atlantic: Costs and Market Trends (October 2024); Rewiring America, Upfront cost of home electrification (March 2024); EIA, Updated Buildings Sector Appliance and Equipment Costs and Efficiencies (2023)). The most useful number here is how much more a heat pump can cost than a like-for-like quote and still come out ahead: get quotes for both and compare.
Labor and rebates
Half of each installed price is treated as labor and scaled by the state's median HVAC installer wage relative to the U.S. median (U.S. Bureau of Labor Statistics). Listed rebates are subtracted when the box is ticked; per-ton rebates assume about one ton of capacity per 600 sq ft. Rebates change often and have eligibility rules, so confirm with the program before you buy.
Not included
Financing, maintenance (similar for all options), local town rebates, and changes in energy prices over time.
