Gas, oil, and high-efficiency furnaces fixed fast — with 24/7 service for the no-heat nights New England is famous for.
Heating repair in Boston spans gas and oil forced-air furnaces and newer high-efficiency condensing units. When the heat quits, the cause is usually a failed ignitor or flame sensor, a worn blower motor, a tripped limit switch, or a thermostat fault — and we diagnose the real problem rather than just resetting it so it doesn't go out again on the coldest night.
With Boston's design temperatures sitting around 7°F, a furnace that short-cycles or can't hold temperature gets exposed fast. We run 24/7 for no-heat calls through the heating season and keep same-day repair slots during the day, so you're not waiting out a cold snap.
Plenty of homes around Boston still run on oil, and we service oil furnaces right alongside gas and high-efficiency systems. That includes the winter safety checks that matter most — inspecting the heat exchanger for cracks that can leak carbon monoxide — because a furnace should be safe as well as warm.
A sound furnace is almost always worth repairing; a unit past about 15–20 years with repeat failures is where a new furnace installation, or a switch to a cold-climate heat pump, enters the conversation. We give you the honest math. If your heat runs on a boiler instead of a furnace, see our boiler and radiator service, or browse all our Boston HVAC services.
Yes. We run 24/7 for no-heat calls through the heating season and prioritize them across Greater Boston, with same-day repair slots during the day.
Short-cycling is often a dirty flame sensor, a failing ignitor, restricted airflow from a clogged filter, or a tripped limit switch. We find the root cause instead of just resetting it, so the furnace holds temperature on cold nights.
If you smell gas or your carbon monoxide alarm sounds, leave and call 911 or your gas utility first, then call us. Otherwise, we inspect the heat exchanger and combustion as part of a no-heat diagnosis to rule out cracks or carbon monoxide risk.
