AfterFast, Reliable Furnace Repair Across Boston
Furnace repair in Boston typically costs between $175 and $825, and when your heat cuts out in a Back Bay brownstone during a January Nor’easter, you need a crew that knows the difference between a dead heat exchanger and a poorly pitched steam return line. Most no-heat calls in Boston’s older housing stock are venting, pitch, or low-water-cutoff issues, not catastrophic equipment failures. We get that. Our techs work in triple-deckers from Dorchester to Mission Hill every week, and a live person answers at (747) 966-3037 whenever your radiators go cold.

Boston homeowners choose us because we treat a South End rowhouse or a Jamaica Plain triple-decker like someone’s home, not a job site. Shoe covers and drop cloths go down before tools come out. Kids’ play areas stay clean. Pets stay safe. Before the crew leaves, you get a photo of the clean-up. That’s included on every job, not sold as an upsell.

Our Furnace Repair team carries parts for nine equipment brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We are qualified to service all of them, which matters when your York furnace is down and a parts house across town is closed.
Emergency Furnace Repair in Boston
Emergency Furnace Repair in Boston means something specific when the design heating temperature outside drops to around 9°F and a Nor’easter is stacking snow past your front steps. A dead furnace in that weather is not an inconvenience. It’s a life-safety issue, especially in pre-war triple-deckers with cast-iron radiators that hold heat for a while but will not carry a family through a multi-day freeze. Call (747) 966-3037 day or night. Emergency furnace repair in Boston runs $175-$825, and we answer live around the clock.
No Heat, Cold Third Floor, Banging Pipes
When a Dorchester triple-decker has a basement boiler still firing while the third floor is ice-cold, the problem is almost never the boiler. It’s usually stuck main vents, a failed low-water cutoff, or return lines that have lost their pitch over 100 years of settling. We diagnose those specific failures before recommending any equipment replacement.
Frozen Condensate and Cracked Heat Exchangers
January freeze events in Boston push high-efficiency furnaces hard. Condensate lines freeze, and heat exchangers crack under thermal stress across repeated cold snaps. We check both before condemning a unit, and our 365-Day Done Right Promise means we never rush a diagnosis just to sell a new furnace.
Furnace Maintenance in Boston
Furnace Maintenance in Boston is not an annual formality when your home was built in 1910 and your furnace shares a basement with 90 years of dust, salt film, and steam piping. In neighborhoods like South Boston and Dorchester, coastal salt air corrodes outdoor burner and condenser cabinets years faster than inland, which shows up as short-cycling and high static pressure. A maintenance visit runs $95-$235 and takes the pressure off before a cold snap.
Annual Inspection and Steam System Tune-Up
In Boston’s older stock, we calibrate main vents, check radiator air vent sizing, inspect low-water cutoffs, and rinse outdoor cabinets to strip salt film. For one-pipe steam systems on Mission Hill or Hyde Square, this keeps the third floor warm and stops the banging. The fix is usually venting or pitch, not a new boiler.
Pre-Winter Furnace Check with Written Report
Before the heating season, we check blower motor draw, capacitor condition, burner flame signal, and safety controls. Our technicians are not paid on what they sell. You get a written report of what we actually found, with prices in dollars before any additional work is approved.
Trusted Brands We Service in Boston
We service most major brands that Boston homes actually run on, including Goodman, Rheem, York, and Daikin, along with Carrier, Trane, Lennox, Bryant, and American Standard. Because we are qualified across nine brands, we can diagnose a Rheem gas valve or a York ignitor without hoping the parts house has inventory. We keep common parts stocked for Boston customers, which shortens repair time when the outside temperature drops. No matter what brand sits in your basement, our techs arrive ready to work on it.
Common Furnace Repair Problems We See in Boston Homes
- One-pipe steam venting and pitch failures in Mission Hill and Hyde Square triple-deckers. These come in as “banging pipes and cold third-floor radiators” and get misdiagnosed as a bad heat exchanger or zone valve. The real fix is main vent calibration and return line pitch, not equipment replacement.
- Coastal salt air corrosion eating condenser coils and outdoor cabinets in Dorchester and South Boston. Short-cycling and high static pressure trace back to salt film on coils, which is why we rinse outdoor cabinets during maintenance calls.
- Nor’easter freeze events driving cracked heat exchangers and frozen condensate lines in January. With 43-plus inches of snow on average, Boston’s heating systems take a beating, and the failure mode is often thermal stress, not age alone.
- Low-water cutoff failures on old steam boilers. A failed cutoff can leave upper floors cold while the basement boiler still fires, which is what we found on a Dorchester triple-decker call where the third floor was ice-cold. We replaced the cutoff, pitched the return line, and installed a new main vent. The whole house was back to even heat the same afternoon.

FAQs About Furnace Repair in Boston
In a Dorchester triple-decker, a cold third-floor radiator while the basement boiler still fires is almost always a venting or pitch problem, not a dead boiler. Stuck main vents, incorrectly sized radiator air vents, or return lines that have lost their slope over decades block steam from reaching upper floors. We fixed this exact problem on a triple-decker where the third floor was ice-cold: we replaced a failed low-water cutoff, pitched the return line, and installed a new main vent. The heat evened out the same afternoon. Call (747) 966-3037 for an exact diagnosis before anyone sells you a replacement.
Yes. Salt-laden air in Dorchester and South Boston corrodes outdoor furnace and condenser cabinets and coils years faster than inland. The salt film drives short-cycling and high static pressure, which is why we rinse outdoor cabinets and coils on maintenance visits. In Boston’s coastal neighborhoods, annual coil rinses and corrosion checks are not optional. Call (747) 966-3037 to schedule a $95-$235 maintenance visit.
Once a year, before winter. Boston’s 1880-1940 housing stock has steam systems, cast-iron radiators, and no legacy ductwork, so maintenance means calibrating main vents, inspecting low-water cutoffs, checking pitch, and rinsing salt film off coastal equipment. Annual maintenance runs $95-$235 and catches the failures that leave upper floors cold in January. Call (747) 966-3037 for a written quote.
Short-cycling in Boston is often a coil problem. Coastal salt air corrodes condenser coils in Dorchester and South Boston, and the resulting high static pressure makes the system cycle on and off too fast. It can also be a heat exchanger issue from Nor’easter freeze stress. Both are diagnosed with a blower motor draw check and coil inspection. Call (747) 966-3037 to find out before the equipment damages itself further.
No, and in a Back Bay brownstone, adding central is not a simple duct-routing puzzle. There is no attic chase, no crawl space, and often no path through load-bearing masonry, so mini-splits are usually the only practical option. But adding cooling does not fix a steam heating problem. The heating issue is venting, pitch, or low-water-cutoff related, and that gets diagnosed separately. Call (747) 966-3037 and we will tell you what is actually wrong before suggesting any equipment.
