A decade ago this was barely a question — most North Shore homes burned oil or gas in a furnace or boiler, end of story. Today, cold-climate heat pumps are a serious contender, pushed along by generous Mass Save rebates and rising fuel costs. So which is right for your home? It depends on your current setup, your fuel, and how you weigh upfront cost against long-term operating cost.
How each one heats
A furnace burns fuel — natural gas, oil, or propane — to create heat and blows it through ductwork as warm air. It is proven, powerful, and delivers hot, forceful heat that feels immediately warm on a frigid day.
A heat pump does not burn anything. It moves heat, pulling warmth from the outside air (yes, even in winter) and delivering it indoors, then reversing in summer to cool the house. It runs on electricity and doubles as your air conditioning, which is a real bonus in older homes that never had central AC.
Do heat pumps work in our winters?
This is the number one worry, and the honest answer is: modern cold-climate models, yes. Today's cold-climate heat pumps are rated to heat efficiently well below freezing — far better than the older units that gave heat pumps a bad name in New England. That said, in the coldest stretches of an Essex County winter, efficiency drops, and many homeowners keep their existing furnace or boiler as backup for the harshest days. That hybrid approach — heat pump most of the year, fossil-fuel backup during deep cold — is increasingly common and often the most practical.
Operating cost
This is where it gets local. Massachusetts has high electricity rates, but heat pumps are extremely efficient, delivering several units of heat per unit of electricity. If you currently heat with oil or propane, a heat pump usually lowers your operating cost meaningfully. If you have cheap natural gas, the savings are smaller and the comparison is closer. Run the numbers for your actual fuel before assuming one wins.
Upfront cost and rebates
A heat pump system generally costs more to install than a straight furnace replacement, especially for whole-home coverage. But this is where Mass Save tilts the field: rebates for qualifying heat pump installations have been substantial, and 0% HEAT Loan financing is available for eligible projects. Those incentives can close much of the gap. A furnace has a lower sticker price and no comparable rebate, so if your furnace just died in January and budget is tight, a like-for-like replacement is the faster, cheaper fix.
Which should you choose?
- Lean heat pump if you heat with oil or propane, want AC too, plan to stay in the home, and can take advantage of Mass Save rebates.
- Lean furnace if you have inexpensive natural gas, need an emergency replacement, or want the simplest hot, powerful heat for a very cold-tolerant home.
- Consider both — a heat pump with your existing furnace or boiler as cold-snap backup gives you efficiency most of the year and full capacity on the worst days.
The best move is a Mass Save energy assessment and a heat-load calculation from a good local HVAC contractor. A well-insulated home makes a heat pump shine; a drafty one may need air-sealing first. Get the house right, then pick the system that fits your fuel, budget, and how long you plan to stay.

Can a heat pump really heat a home through a Massachusetts winter?
Modern cold-climate heat pumps are rated to heat efficiently well below freezing and handle most of our winter fine. In the coldest stretches, efficiency drops, so many homeowners keep an existing furnace or boiler as backup for the harshest days.
Is a heat pump cheaper to run than a furnace?
It depends on your current fuel. Compared with oil or propane, a heat pump usually lowers operating costs despite high electric rates, because it is so efficient. Against cheap natural gas the comparison is closer. Run the numbers for your actual fuel.
Do I have to remove my furnace to install a heat pump?
No. Many North Shore homeowners keep the existing furnace or boiler as backup heat for the coldest days and run the heat pump the rest of the year. This hybrid setup captures most of the efficiency while keeping full capacity in a deep freeze.
Does Mass Save help pay for a heat pump?
Yes. Mass Save offers substantial rebates for qualifying heat pump installations and 0% HEAT Loan financing for eligible projects, which can offset much of the higher upfront cost. Amounts change periodically, so confirm current figures with a participating installer.
