What matters for furnace repair in Marlborough
Gas and oil
Both fuels are common. Oil furnaces need annual nozzle and filter service; gas furnaces need clean flame sensors and clear vents.
High-efficiency venting
Newer furnaces vent through plastic pipes on side walls. Snow drifts can block them and shut the furnace down.
Shared ducts with AC
Many homes share ductwork between heat and central air. A failing blower affects both seasons.
Condos and townhouses
Furnaces in closets or attics of attached homes can be harder to reach. Mention it when you call.
Warning signs to watch for in Marlborough homes
- No heat or cold air from vents
