Heating tune-up in Medford
Natural gas heats 62% of Medford (15,034 homes), which makes the gas furnace or boiler the usual job: flame, heat exchanger, venting and safety devices.
Across the three burner fuels, 19,105 of 24,339 homes (78%) burn gas, oil or propane: 15,034 gas, 3,543 oil and 528 propane. 11,180 homes (46%) are rented, which means the landlord, not the tenant, books the visit. Homes here are old: the median was built in 1942. Basements often hold equipment from several different decades.

Replacing a boiler or furnace in Medford
Gas is the default in Medford (62%), and the rebate only follows if a Mass Save gas sponsor serves you. The gas bill tells you who that is. Rates and the January 1, 2027 drop are on the 2027 rebate page.
For a number you can use, send two photos of the old unit and the panel, and see what moves a boiler price.
What next
Estimate your rebate. Most homes here burn gas, so read the gas guide. If you have an oil tank, see oil to heat pump. Landlords: heat pumps for two- and three-families. A heat pump adds load, so check your panel.
