Fast, Reliable Furnace Repair Across Dedham
Furnace repair in Dedham typically runs $150 – $700, and most no-heat calls can be diagnosed and fixed in one visit. If your system is down on a cold January night near Dedham Square or off Route 1, you need a tech who knows the difference between a 1920s home’s boiler and a 1990s gas furnace, and who shows up inside the window. That’s what we do. Dalton Heating & Air has served Dedham homeowners with written pricing before any work starts, and every repair carries a full-year guarantee. Call (361) 306-9515 and you’ll reach a live person, 24/7.
Why Dalton Heating & Air Is Dedham’s Preferred Furnace Repair Company
Dedham homeowners have put up with enough no-shows and price shifts at the door. Our Google reviews from Dedham customers tell a consistent story: the tech showed up on time, put the price in writing, and left the basement cleaner than he found it. That consistency is not luck. It is The Garrison Standard, the operating code we have followed since 2003 under the Garrison Partners network. Every tech arrives background-checked and in uniform, knows the route into Dedham, and carries parts for both high-velocity and conventional systems.
Response time to Dedham is inside the stated window, every time. Scheduling is coordinated from our Boston office, but crews are dispatched locally and know the short streets off High Street and the newer subdivisions near Route 1 without a GPS guessing game. When a homeowner in the Dedham Square Historic District calls with no heat, we do not put them in a callback queue. We answer, we schedule, we show up.
Marco Benitez, who leads our team, holds every tech to one rule from The Garrison Code: price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year. That means no “while we’re here” surprise add-ons. No second visit charge if the repair fails inside the guarantee period. Just the repair, done right.
Boiler Repair in Dedham
Boiler Repair in Dedham is a different discipline than furnace work, and a lot of the housing stock here still runs on hydronic heat, especially the 1920s Colonials around Dedham Square and East Dedham. Those systems have cast-iron sections, circulator pumps, zone valves, and expansion tanks that a furnace tech never touches. When a boiler cracks a heat exchanger or a circulator seizes in January, the repair is urgent and often requires a part that is not sitting on a big-box shelf. Our techs carry discontinued hydronic sections and know where to source the rest locally. Boiler repair in Dedham runs $150 – $700 depending on whether we are replacing a gas valve, a pump, or a section. We give you that range in writing before we open the panel.
Heat Exchanger Repair and Replacement
A cracked heat exchanger on a boiler is not a patch job. It is a carbon monoxide risk and a system that has reached the end of its safe life. In older Dedham boilers, we see cracks that have gone unnoticed for seasons because nobody ever tested combustion. We test on every no-heat call, and if the section is done, we tell you straight. Repair is not always the right answer, and we will not pretend otherwise.
Circulator Pump and Zone Valve Work
When one floor of a Dedham house is warm and another is cold, the culprit is usually a stuck zone valve or a weak circulator. These parts wear out on their own schedule, regardless of the boiler’s age. We replace them with the same brands the system was built around, and we wire them back by the book.
Gas Furnace Repair in Dedham
Gas Furnace Repair in Dedham covers everything from a dirty flame sensor to a full blower motor replacement on forced-air systems common in homes built from the 1960s onward. The most frequent call we get from Dedham homeowners is a system that fires up and then shuts down before the house warms. That is an ignition lockout, and in Dedham’s humidity swings, dirty flame sensors and failing thermocouples cause most of them. A standard gas furnace repair in Dedham runs $150 – $700. You will know the exact number before we start, in writing.
Ignitor and Flame Sensor Replacement
Hot-surface ignitors crack, flame sensors oxidize, and both failures mimic a dead furnace. On a Rheem or Goodman gas furnace, the ignitor sits in the flame path and fails from sheer thermal cycling. We replace what is actually broken, not what is convenient to bill.
Gas Valve and Blower Motor Repairs
A faulty gas valve either will not open or will not regulate pressure correctly, and both conditions are dangerous. Blower motor failure usually announces itself with a smell, a hum, or a furnace that runs but never moves air. On older Dedham homes with undersized ductwork, high static pressure kills blower motors early. We check the static pressure on every motor replacement, not just the motor.
Trusted Brands We Service in Dedham
Our techs are factory-trained on the systems Dedham actually has in its basements: Trane, Lennox, Goodman, and Rheem, plus Carrier, York, Bryant, Daikin, and American Standard. We stock ignition components, sensors, pressure switches, and blower motors for those brands so most Dedham repairs do not wait on a parts shipment. On older Lennox or Trane furnaces where a board or inducer is obsolete, we source locally and often have common replacements on the truck. A 1980s Carrier off High Street is not a mystery to us, it is a Tuesday.
Common Furnace Repair Problems We See in Dedham Homes
- Cracked heat exchangers in aging boilers and gas furnaces. These often go unnoticed until a carbon monoxide test or a no-heat call reveals them. In Dedham’s older housing stock, the average furnace we condemn is well past its design life, and the crack is often in a discontinued section that needs real sourcing, not a generic replacement.
- Dirty or failed flame sensors and thermocouples from Dedham’s humidity swings. Spring and fall humidity cycles coat sensors in oxides and cause intermittent ignition lockouts. The furnace lights, runs for thirty seconds, and shuts down before the house reaches setpoint.
- Undersized ductwork and high static pressure on older homes. Many Dedham homes were retrofitted for forced air decades ago, and the ducts never matched the system. The result is short cycling, cold rooms, and blower motors that die early. We measure static pressure as part of any blower motor repair.
- Short cycling from oversized furnaces. A furnace that is too big for the house heats the air too fast, shuts off, and repeats. It also exaggerates cold spots in rooms at the end of long duct runs, which we see often in split-level and expanded Capes around Dedham.

Dedham’s housing stock swings from 1920s Colonials near the Dedham Square Historic District to 1990s builds off Route 1, so our techs carry both high-velocity and conventional replacement parts. A failed heat exchanger on an old boiler often means sourcing a discontinued section, not a trip to a big-box store. That local knowledge is why the price we quote is the price you pay, and why we can give it in writing before any work begins.
We recently got a no-heat call from a homeowner on High Street in the Dedham Square Historic District whose 1980s Carrier gas furnace kept tripping its high-limit switch. Our tech found a cracked heat exchanger and a blower motor pulling high amps. After a load calculation confirmed the right tonnage, we installed a new 96% AFUE Carrier and corrected static pressure in the ductwork. The homeowner had heat back the same day and a system that no longer short-cycles.

FAQs About Furnace Repair in Dedham
Yes. Boiler repair in Dedham is a core part of our work, especially in the pre-war housing stock around East Dedham and the Colonial neighborhoods near Dedham Square. We service cast-iron and condensing boilers, including heat exchanger, circulator pump, zone valve, and expansion tank work. Boiler repairs run $150 – $700, same written-price and one-year guarantee as our furnace work. Call (361) 306-9515 to schedule a boiler tech.
Use this simple framework. If the repair is under $500, the furnace is under 15 years old, and the heat exchanger is intact, repair almost always makes sense. If the heat exchanger is cracked, the repair exceeds half the cost of a new system, or your furnace is over 20 years old and short-cycling, replacement usually wins. We test combustion on every no-heat call in Dedham, and we will give you both numbers in writing so you can decide with facts. Call (361) 306-9515 for an honest assessment.
Most furnace repairs in Dedham run $150 – $700. Common jobs like flame sensors, ignitors, thermocouples, and pressure switches land in the $150 – $350 range. Blower motors, gas valves, and heat exchanger work push toward $400 – $700. Every repair comes with a written price before work starts and a one-year written guarantee. Call (361) 306-9515 for an exact quote on your system, free.
Short cycling in older Dedham homes usually comes down to two things: an oversized furnace or undersized ductwork. A furnace that is too big heats air too fast and shuts down before air reaches the far rooms. Undersized ducts create high static pressure that shortens blower motor life and starves distant registers. We measure both on every call, and we do not replace a motor without checking the pressure behind it. Call (361) 306-9515 and we will diagnose it properly.
Yes. We are factory-trained on nine major residential HVAC brands, including Trane, Lennox, Goodman, Rheem, Carrier, York, Bryant, Daikin, and American Standard. We stock common parts for those systems and source discontinued sections for the older boilers and furnaces that big-box stores no longer carry. If your Dedham home has a 1980s Carrier or a newer Lennox, we have the part and the training. Call (361) 306-9515 to describe your system and we will tell you what to expect.
