Common Questions
How much does furnace replacement cost?
It depends on size, efficiency and ductwork. After an in-home visit you get a written quote with any rebate already applied.
Is there a Mass Save rebate for gas furnaces?
Mass Save offers rebates on qualifying high-efficiency equipment. Amounts change, so we check your current eligibility at the visit.
Do I have to wait for my rebate check?
No. We process the paperwork and apply the rebate as a discount when you sign.
Can I finance a new furnace?
Yes, through GreenSky or the Mass Save HEAT Loan, with 0% options for qualifying projects.
Do you install propane furnaces?
Yes. We install gas, oil and propane furnaces.
Should I switch to a heat pump instead?
It depends on your home and fuel costs. Mass Save rebates are often larger for heat pumps, and we can quote both.
