Furnace Repair in Boston - Fixed Today, No Surprise Invoice

Fast, 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.

Why Meadowsweet Heating & Air Is Boston’s Preferred Furnace Repair Company

We’re part of the Cedarwell family of HVAC companies, founded in 2004, and every job in Boston carries the Cedarwell Care Promise. That means a written price before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise behind every repair. If it’s not done right, we make it right. No runarounds, no fine print.

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.

Luis Serrano leads our Boston dispatch. When you call, a live person picks up, 24 hours a day, including weekends and holidays. No voicemail queue, no answering service runaround. We coordinate scheduling from our Boston office, and our crews serve the neighborhoods you actually live in: Roxbury, Beacon Hill, Southie, Hyde Square, and the rest.

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.
