Short answer
Modern cold-climate heat pumps can heat Massachusetts homes through most winter weather, and they also provide air conditioning. A furnace delivers very hot air quickly and works independently of outdoor temperature. Many homeowners choose a dual-fuel setup: a heat pump for most of the season with the furnace as backup on the coldest days.
How they differ
A furnace burns gas, oil or propane to heat air. A heat pump uses electricity to move heat from outdoor air into the house, even in cold weather, and reverses in summer to cool.
- Furnace: hot supply air, works at any outdoor temperature, needs venting and fuel
- Heat pump: heating and cooling in one system, no combustion in the house, efficiency drops as it gets colder
- Dual-fuel: heat pump plus furnace, with controls choosing the cheaper or more effective source
What affects operating cost
Running costs depend on local electricity and fuel prices, the heat pump's efficiency at low temperatures, the home's insulation and air sealing, and how the controls are set up. A heat-loss calculation for your house is the right starting point, not a rule of thumb.

If your furnace is failing mid-winter, a repair may buy time to plan a heat pump project properly in the off-season.
Related questions
Do heat pumps work below freezing?
Cold-climate models are designed to keep heating well below freezing, with reduced capacity in extreme cold. Sizing and backup heat matter.
Can I keep my furnace if I add a heat pump?
Yes. A dual-fuel setup keeps the furnace as backup and is common in New England.
Will a heat pump fix my uneven heat?
Not by itself. Uneven heat is often a duct or insulation problem that affects either system.
