AfterFast, Reliable Furnace Repair Across Boston
Furnace repair in Boston typically runs $175 – $825 depending on the part that failed, and most calls are completed in a single visit. That’s a wide window because a $175 ignitor replacement and a $825 blower motor job are different animals entirely. You’ll know the exact number before any tool comes off the truck: the price goes in writing first, every time. If you’re sitting in a cold house in Boston tonight, call (361) 306-9515 and a live person picks up, not a voicemail queue.
We work across the city daily, from triple-deckers in Dorchester to converted Victorians in Jamaica Plain to newer condos in Seaport. Boston’s housing stock runs old, and old furnaces have old-furnace problems: cracked heat exchangers, tired ignitors, and gas valves that stick when you need them most. Our crews know which issues show up in which neighborhoods because we’re here every week, not driving in from an hour away.
Why Dalton Heating & Air Is Boston’s Preferred Furnace Repair Company
Dalton Heating & Air operates under The Garrison Standard, a set of rules that has governed how we work since 2003. Every job gets a written price before work starts. Every repair carries a written guarantee for a full year. If the repair fails inside that year, we come back at no charge. Those are not upgrades or add-ons; they are the terms of the job, on every single call, without exception.
Homeowners in Boston have told us the same stories enough times that we’ve built the company around fixing them. Technicians who show up two hours late or not at all. Quotes that balloon once the work begins. Repairs that fail in three weeks and nobody returns the phone call. Marco Benitez, who leads our Boston team, runs a crew that arrives inside the stated window, in uniform, background-checked, and ready to explain what’s wrong in plain English before touching anything.
Dispatch and scheduling for our Furnace Repair team are coordinated from our Boston office, so the person you talk to knows the city and can route a technician who’s already in your part of town. Live phone support is staffed around the clock. When you call at 2 a.m. from an Allston apartment with no heat in January, a human answers and starts the process. Not a callback request.
Boiler Repair in Boston
Boiler Repair in Boston is a specialty call that trips up a lot of HVAC companies, because boilers are still common across the city’s older housing stock and repairing them properly means understanding hydronic systems, not just swapping parts. Radiators, circulator pumps, expansion tanks, pressure relief valves, and the boiler itself all have to play together. Boston homes in neighborhoods like Roslindale, West Roxbury, and Hyde Park still run steam and hot-water boilers that are forty, sixty, sometimes eighty years old.
A boiler that makes banging sounds, runs but won’t heat certain rooms, or loses pressure repeatedly is calling for attention. Most boiler repairs in Boston fall inside the $175 – $825 range, with the lower end covering parts like aquastats and pressuretrols and the upper end covering circulator pump replacements or zone valve work. We diagnose first, quote in writing, and you decide.
Circulator and Zone Valve Diagnosis
When some rooms heat and others don’t, the problem usually sits in the circulator pump or a zone valve that has stopped opening. Both of those are common on Boston’s multi-floor homes where a single boiler feeds two or three thermostats. We test before replacing. A $175 part swap beats a $825 guess any day.
Pressure and Expansion Tank Issues
Older Boston boilers often run with undersized or waterlogged expansion tanks, which pushes system pressure into the danger zone and can trip the relief valve. Letting that ride can damage the boiler itself. We check pressure on every boiler call and quote the fix in writing, whether it’s an air charge or a full tank replacement.
Gas Furnace Repair in Boston
Gas Furnace Repair in Boston covers the forced-air systems that heat most of the city’s newer construction and a good share of its older single-family homes too. If your furnace fires up, runs a few minutes, and shuts off before the house warms, or it won’t light at all, something in the ignition, gas supply, or safety circuit is failing. Boston’s damp winters make furnaces work hard, and a system that gets a workout every day from November through April shows wear in predictable places.
Repair costs for gas furnaces in Boston match the same $175 – $825 window. An ignitor or flame sensor runs on the low end. A blower motor or gas valve lands higher. You’ll see the exact number in writing before we start, and the repair is guaranteed in writing for a full year. If it fails inside that year, we return at no charge. That’s the 365-Day Done Right Promise, and it’s standard on every job.
Ignition and Flame Sensor Failures
Short cycling and no-heat calls in Boston are often traced to a cracked ignitor or a dirty flame sensor. These are quick fixes with parts we keep on the truck. Most of these jobs land between $175 and $350 and are done in under an hour.
Blower Motor and Gas Valve Replacement
When the furnace lights but the air never moves, the blower motor is the usual suspect. When it won’t light at all and the ignitor tests fine, the gas valve has likely failed. Both fall into the higher end of the $175 – $825 range because the parts cost more and the labor takes longer. We quote before we touch it, so there’s no surprise at the end.
Trusted Brands We Service in Boston
Our technicians are factory-trained to service nine major residential HVAC brands, and in Boston we see a steady stream of Goodman, Rheem, and York furnaces across the city’s neighborhoods, plus plenty of units that need Boston Carrier service. Parts availability matters in this business, and we keep common repair parts for those brands stocked locally so a furnace in Cambridge or Everett isn’t waiting three days on a shipment. Daikin systems show up regularly in newer condos around Brighton and the South End, and we service those as well. When your furnace is down, the brand on the cabinet shouldn’t dictate whether you get heat back tonight. We work on all of them.
Common Furnace Repair Problems We See in Boston Homes
- Cold spots in triple-deckers and converted multi-families: Boston’s older homes were often retrofitted for forced air, and ductwork wasn’t always the priority. Uneven heating from floor to floor is common, and we diagnose whether it’s a blower issue, a zone damper, or a duct problem before recommending any repair.
- Short cycling in drafty older homes: Victorian-era houses in Dorchester and Roxbury lose heat fast. When a furnace runs four times an hour instead of twice, the ignitor and blower motor wear out years early. We fix the component and tell you what’s causing the strain.
- Frozen condensate lines in high-efficiency furnaces: Boston winters drop below freezing often enough that condensate drains on 90%+ efficiency furnaces can freeze and trigger a shutdown. Routing the line correctly and adding proper insulation fixes it for good, and it’s a repair we do regularly from December through March.
- Sticking gas valves in seaside neighborhoods: Homes near the water in East Boston and South Boston see more corrosion on gas valve connections and control boards, thanks to salt air. A furnace that hesitates to fire on a January morning is often a gas valve that’s gummed up or failing.
Pricing for Furnace Repair in Boston, MA
