Your house probably isn’t the same age as the one three blocks over, and in Newton that gap can be 100 years. Nonantum and parts of West Newton have homes from the mid-1800s. Newton Centre is mostly 1890 to 1940 Colonials, Tudors and Victorians, and Oak Hill is largely post-war. Each one heats and cools differently, so the right HVAC installation in Newton starts with your house, not a product catalog.
That changes what you walk away with. A radiator system in an older Newton house gets judged on its own terms, so you hear whether it can keep going or whether it’s time to talk options. A plaster-walled home with no ductwork gets an honest conversation about ductless instead of a quote that means opening up walls. And if you’ve been wondering about a heat pump, you hear what it can and can’t do in a Newton winter. The city counts about 1,500 installed between 2019 and 2025, so your neighbors are asking the same thing.
You also get fewer surprises. Between hospital shifts, a commute on the Green Line or the Massachusetts Turnpike, and a house worth protecting, you don’t have time for a job that grows halfway through. Good HVAC repair in Newton means a written scope, your approval before work starts, and a follow-up after it ends. Our heating and cooling services in Newton are built around that.
Dempsey Energy is a family-owned HVAC, plumbing and electrical company headquartered in North Attleborough, and we’ve worked with Massachusetts homeowners for decades. If you’re looking for an HVAC company in Newton that can handle a boiler, a furnace, an oil burner, a heat pump or a mini-split without passing you along, that range is the point. It matters in a Middlesex County basement where the heating, the water heater and the sump pump often share one corner.
We’ve learned that most communication issues trace back to unclear explanations, so that’s where we focus: explaining the problem before recommending a fix, putting the scope in writing, tracking every job and following up when it’s done.
Whether you’re in Waban, Newton Highlands or Newton Upper Falls, the house in front of us decides the plan. We’re also a Mass Save partner, which helps when a heat pump is on the table.
It starts with a look at what you actually have. A technician checks the age and condition of the system, what fuel it runs on, where it sits, and how heat or cooling gets through the house, whether that’s radiators, ducts or neither. You hear the concern in plain terms before anyone recommends a fix, and where possible you’re shown what’s failing.
Next comes the decision. If a repair makes sense, we’ll tell you that. If replacement is the better call, you get options. For a heat pump, that includes a proper load calculation so the system is sized to your house, which Mass Save rebates call for anyway. Nothing starts until the scope and price are in writing and you’ve said yes.
Newton adds paperwork worth knowing about. Replacing equipment generally takes a mechanical permit through the city’s Inspectional Services Department, and gas work needs its own permit. Any residential HVAC contractor in Newton should walk you through what your project needs. If you’re planning an addition or major renovation, we raise the city’s all-electric requirement before HVAC installation in Newton gets planned around the wrong equipment.
Then we follow up. Timing helps too: boilers and furnaces are easier to schedule in spring or early fall than during the first cold snap.

Our heating and cooling services in Newton fall into three groups. Heating covers furnaces, boilers, oil burners, gas heaters, oil tank replacement and removal, and heat pumps. Cooling covers AC repair, installation and maintenance, plus mini-splits for plaster-wall houses where ducts don’t fit. The third group is everything else down there: water heaters, sump pumps, thermostats, indoor air quality and electrical work. As a residential HVAC contractor in Newton, that range matters because one basement often holds three of those systems.
For planned work, there’s the Dempsey Comfort Club. Members get an annual maintenance visit, priority scheduling, and discounts on parts, labor and repairs. HVAC maintenance services in Newton make the most sense before heating season, especially for an older boiler or oil burner. We check the system, explain what we found, and separate what needs attention now from what can wait. Many manufacturers also require annual maintenance to keep warranty coverage, so keep the paperwork.
Heat pump conversions add a few extras. Your electrical panel may need an upgrade, and an oil tank may need to be removed or decommissioned. Those go in the written scope up front, along with any Mass Save paperwork. Ask which installs carry our 10-year manufacturer and labor warranty, since it applies to select systems. If your home is in Auburndale, Chestnut Hill, Newtonville or Upper Falls, tell us early so we can flag any historic-district questions for the city.
Almost always, yes, if you’re swapping equipment. In Newton, a mechanical permit comes through the city’s Inspectional Services Department, and gas work needs a separate gas permit. We file both as the licensed contractor, not you. Replacing a single part during a repair is a different situation, so ask before assuming either way.
The application is where you can tell a careful company from a careless one. Newton asks contractors for license copies, a workers’ compensation affidavit and an insurance certificate naming the city. If an HVAC contractor in Newton tells you the permit isn’t needed and wants to skip it, push back. Unpermitted work can complicate an inspection, an insurance claim or a future sale, and that matters when houses here are worth what they are. Fees and rules change, so we’d confirm current details with the city for your address.
It depends on what you’re doing. Newton is one of 10 Massachusetts communities in the state’s Fossil Fuel-Free Demonstration Project. Its ordinance requires electricity for heating and cooling in new construction and major renovations, and electricity or thermal solar for hot water. Changes began January 1, 2025, and as of January 1, 2026, major renovations and additions over 1,000 square feet can no longer keep gas cooking.
What the city’s published material doesn’t clearly spell out is how this applies to replacing an existing boiler or furnace like for like. We won’t guess, and neither should anyone else. Call Newton’s Inspectional Services Department, or ask us to check for your project. If you’re planning an addition or a gut renovation, bring it up before you choose equipment, because the answer will most likely be a heat pump. We install oil, gas and heat pump systems, so our job is to tell you what your project can actually use. That’s how HVAC installation in Newton avoids a redo.
Often, yes, and it’s a common situation in Newton. Many pre-1940 houses in Newton Centre, West Newton and Nonantum are heated by radiators with no ducts, and plaster walls make adding ductwork messy. A ductless mini-split avoids that. An outdoor unit connects to indoor heads on the wall, and a cold-climate model heats as well as cools. That’s useful if your house has oil heat and never had central AC.
Whether it carries your house through a Newton winter comes down to sizing. A proper load calculation looks at your insulation, windows and layout, not just square footage, and an undersized system is where most heat pump skepticism comes from. Mass Save rebates generally apply to qualifying equipment that replaces or supplements oil, propane or electric baseboard heat, so a gas-heated home may not qualify. If you’re in a historic district, ask the city about where outdoor equipment can go. A residential HVAC contractor in Newton should raise that before the install, not after.
Start with age. Central AC and heat pumps typically last 10 to 15 years, and furnaces and boilers about 15 to 20. Past those ranges, repairs come more often, and a failure tends to land when you can least afford it, like the first deep freeze of the season. In a Newton house where the boiler came with the purchase and nobody kept the paperwork, it’s worth finding out how old it really is.
Then look at the repair itself. A part on a seven-year-old furnace is simply a repair. A major repair on a 20-year-old boiler is a different conversation. We’ll tell you the age, what’s wrong, what it costs to fix and what replacement would involve, so you decide with the full picture. If repair is the right call, we’ll say so. A yearly visit through HVAC maintenance services in Newton is how you stretch a healthy system further and catch a weak one early.
It depends on the system, the house and what the install involves, so we’d rather quote after seeing yours than toss out a number. For context, third-party Massachusetts guides put full system replacement at roughly $5,500 to $19,000. Within that, a gas furnace runs about $3,500 to $8,500, a ducted heat pump $7,000 to $16,000, and a single-zone mini-split $3,500 to $9,000. Greater Boston tends to run about 15 to 20 percent above the state average. Those are outside estimates, not a Dempsey Energy quote.
What moves the price: system type, home size and layout, the condition of existing ductwork, whether a heat pump needs an electrical panel upgrade, efficiency level, permits, and whether you qualify for rebates. Older Newton houses often add access and wiring questions that a newer build doesn’t. Ask any HVAC company in Newton for the scope in writing, so you can compare quotes line by line instead of by the total.
A few, and they work in different ways. The Dempsey Comfort Club gives members an annual maintenance visit, priority scheduling and discounts on parts, labor and repairs, which adds up for older boilers and oil burners that need regular attention. Our website also lists limited-time coupons, such as $50 off any heating or cooling service and $500 off a new heating system installation. That second one can’t be combined with other offers, so check the Coupons page for what’s current.
The bigger savings in Newton often come from Mass Save. Qualifying heat pumps can earn rebates, and the HEAT Loan offers 0% interest on up to $25,000. Newton also has a Community First Partnership with income-based help, including no-cost home energy assessments and weatherization, and heat pumps up to no cost for eligible households replacing oil, propane or electric resistance heat. Eligibility depends on the equipment, the installer and your home, so ask us whether you qualify before you commit. For anyone pricing HVAC repair in Newton or a full replacement, those programs are worth a few minutes.
