Furnace repair in Newton, MA starts with a simple fact: about half the homes here were built before 1939. The furnace in one of those houses is rarely the original. It’s usually a replacement that has been worked around additions, old ductwork, and plaster walls, so a furnace not heating in Newton, MA could be a failed part, an airflow problem, or a unit near the end of its life.
Once someone sorts out which one it is, you stop guessing. A bad ignitor and a 20-year-old furnace call for very different decisions, and you should hear both sides before you spend anything.
Newton’s winters give that decision some weight. January lows average roughly 18 to 22°F, and about 127 nights a year fall below freezing, so whatever we fix has to hold up for a long season. The houses also change from village to village: many early-1900s estates in Waban and Chestnut Hill, two-families in Newtonville and Nonantum, post-war homes in Oak Hill. A tech who treats them all the same will miss things.
What you walk away with is a system that runs, a clear picture of what comes next, and no pressure to make a bigger decision in a cold house.
Dempsey Energy is a family-owned company that started in 1992 as an oil company, then grew into licensed HVAC and plumbing work, with electrical now added. More than 12,000 customers have called us since. That oil background is why a burner, a fuel line, or an older gas furnace doesn’t throw us.
Newton is thirteen villages, not one downtown, and the houses change from Auburndale to Oak Hill to Newton Upper Falls. Our office is in North Attleborough, so we won’t pretend to be on your corner. We serve Newton and Greater Boston homeowners the same way everywhere: someone answers the phone around the clock, the options get explained in plain words, and every job is tracked so someone follows up afterward.
If you’re also thinking about furnace maintenance in Newton, MA before the next heating season, that’s a normal reason to call, not just a breakdown.
Call any hour and a live person answers. You describe what the furnace is doing, and we set the appointment. The $99 dispatch fee is collected when the appointment is booked, and it covers a 15-minute diagnostic. If we find the problem within those 15 minutes and you go ahead with the repair, the fee is waived. If diagnosis takes longer, the $99 still applies, so you know the rule before anyone shows up.
On site, furnace troubleshooting in Newton, MA starts with the basics: thermostat settings, filter, power, and fuel supply. In an older house, the next look is usually airflow, because patched-together ductwork changes how a furnace behaves. Combustion analysis and a heat exchanger inspection are part of how we check a system, and they matter most on older equipment.
Then you get options with the cost of each, and you decide. Our trucks are fully stocked, so many repairs can be finished during that visit, though a hard-to-find part on an older unit can mean a second trip. Where a permit is required, it goes through Newton’s Inspectional Services Department, which handles gas, plumbing, and electrical permits through the city’s online portal.
After the work, we follow up. A fall visit, before the roughly 43 to 52 inches of annual snow arrives, is the least stressful time to have a furnace looked at.

We repair gas, oil, and electric furnaces and service oil burners, which matters in a city where older homes have changed fuels and equipment over the decades. If your house in Newton Centre or Waban runs on a boiler and radiators instead of vents, we handle boiler repair too. Our residential furnace repair in Newton, MA covers everything from single-families in Oak Hill to two-families in Newtonville.
Gas furnace repair in Newton, MA usually comes down to a short list of parts: flame sensors, ignitors, blower motors, and control boards. Nationally, Angi puts a typical furnace repair between $133 and $505. An ignitor runs $150 to $250 to replace, and after-hours work can push that to $350 to $500. Emergency furnace repair in Newton, MA is available 24/7, and it helps to know those numbers before anyone quotes you.
Maintenance is where you catch a dirty flame sensor or a clogged filter before January does. The Dempsey Comfort Club is our membership program, and it includes a free annual tune-up, 10% off parts, 10% off labor, priority servicing, and 24/7 emergency service. A standalone tune-up typically runs $150 to $200 nationally, so the free visit counts for something. Priority servicing matters most when a snowstorm takes out everyone’s heat at once.
Start with the simple causes. A thermostat fan set to ON instead of AUTO, a clogged filter that trips the high-limit switch, and a dirty flame sensor are the most common reasons a furnace runs but blows cold air or won’t stay lit. Repeated failed ignition attempts can also lock the furnace out until it’s reset.
Older Newton houses add another possibility. Many have ductwork that was extended or patched over the years as rooms were added, so airflow problems can look like a furnace failure. A unit past 15 years can also simply be wearing out.
Check the thermostat, the filter, and the furnace’s power switch. If that doesn’t fix it, or if you smell gas, notice a burning odor, or see soot, stop and call. Combustion and fuel lines are licensed work and not a DIY job.
Our dispatch fee is $99. It’s collected when the appointment is set and covers a 15-minute diagnostic. If we find the problem within 15 minutes and you proceed with the repair, the fee is waived. If diagnosis runs longer than 15 minutes, the $99 still applies.
The repair itself depends on which part failed, the fuel type, the age of the furnace, and the time of day. For reference, Angi’s national data from nearly 28,000 projects shows most homeowners paying between $133 and $505, with an average of $318. After-hours calls cost more across the industry, and emergency labor can run $150 to $215 an hour.
In Newton, older equipment can make parts harder to find, which affects the total. We don’t publish flat repair prices because the failed part decides the number, but you’ll see the cost of each option before any work starts.
The age of your house and the age of your furnace are two different questions. Gas furnaces typically last 15 to 20 years, and ENERGY STAR suggests considering replacement after 15. A common rule of thumb is to think about replacing when the repair would cost more than half of a new unit, or when you’re calling for repairs every year.
If the furnace is under 15 years old and the problem is one part, repair is usually the better value. If it’s 20 years old, the heat exchanger is cracked, or you’ve had repeat breakdowns, replacement starts to make sense.
Many Newton homeowners are also weighing a switch to electric heat at some point. Repairing a working furnace is a legitimate way to buy time while you plan. We’ll lay out the options and the numbers, and the decision stays with you.
Newton is one of 10 Massachusetts communities in the state’s fossil-fuel-free demonstration project. The city says new construction and major renovations must use electricity instead of fossil fuels for heating, cooling, cooking, and clothes drying. As of January 1, 2026, major renovations and additions over 1,000 square feet must be fully all-electric.
Those rules are aimed at new construction and major projects. We haven’t seen anything saying an existing gas or oil furnace has to come out or can’t be repaired, so repair is not restricted.
Rules for replacing a unit and the permits involved are a separate question. Newton’s Inspectional Services Department at City Hall, on Commonwealth Avenue, handles gas and plumbing permits. If you’re planning a bigger project, check with them first. We can walk you through what the work involves.
Run through a quick checklist first. Make sure the thermostat is set to heat and the fan is on AUTO. Check that the filter isn’t clogged, that the furnace’s power switch and your breaker are on, and, if you heat with oil, that the tank isn’t empty. If the furnace has locked out, one reset is reasonable. Repeated resets are not.
This matters most for households that come home after dark. Newton’s January lows average roughly 18 to 22°F, so a furnace that went down midday can leave a cold house by evening. If you’re searching furnace repair near you from that house, a few minutes of furnace troubleshooting in Newton, MA can sometimes save you a call.
Stop and leave the house if you smell gas or your carbon monoxide alarm goes off. Otherwise, call us. Someone answers 24/7, and Dempsey Comfort Club members get priority servicing.
For many Newton homes, it can. Older equipment is more likely to fail, and about 127 nights a year fall below freezing here, so the furnace works hard for a long stretch. The Dempsey Comfort Club includes a free annual tune-up, 10% off parts, 10% off labor, priority servicing, and 24/7 emergency service.
The tune-up is the easiest piece to put a number on. A standalone tune-up typically costs $150 to $200 nationally, and it’s the visit where a worn flame sensor or a dirty burner gets caught before it becomes a breakdown. The 10% off parts and labor adds up if a repair does come, and priority servicing helps when a snowstorm hits and every heating company is swamped.
We don’t publish a membership price, so ask us for the current one before you decide. If your furnace is nearing the end of its life, the discounts help on repairs while you plan what comes next.
