About half the homes in Newton were built before 1940, and the median house dates to 1942. Whoever framed that Queen Anne in Newton Centre or that Shingle Style house in Chestnut Hill rarely planned for cooling ducts. They heated with radiators and opened windows.
That’s why air conditioning installation in Newton, MA starts with the house, not a catalog. A central AC system with a short duct run can work where the framing has room. Zoned systems and ductless mini-splits handle the places where it doesn’t, and a mini-split needs little more than a small opening through an exterior wall. Your technician explains which one fits and why, and you choose.
Afterward, the third floor stops being the room everyone avoids in July. The finished attic or sunroom gets its own control instead of borrowing from the rest of the house, and your plaster, millwork and woodwork stay where they are. When the typical Newton home is worth around $1.5 million, that matters more than who quoted lowest.
You also stop planning your summer around the city’s cooling spots. When Newton hit 101°F in June 2024, schools cut days short, and the library and Senior Center were closed for the holiday. Residential air conditioning in Newton that fits your house means the cool room is the one you live in.
Dempsey Energy is a family-owned company that began in 1992 as an oil company, started by Law and Nancy Dempsey. The next generation added licensed HVAC, plumbing and electrical work, so a cooling job that touches a condensate line or an electrical disconnect doesn’t need a second contractor.
That heating background pays off in Newton. The older house that needs cooling usually has a boiler or furnace aging right alongside it, and you should be able to plan both without buying twice. Our technicians are NATE-certified, which is the independent credential for people who install and service this equipment, and we’re licensed and insured.
Based in North Attleborough, we handle AC services in Newton and neighboring Wellesley. Over more than 30 years we’ve worked with about 12,000 customers. When you call, you get a Home Comfort Advisor for direct, individual contact, and a follow-up afterward so your job doesn’t get lost.
It starts with a call. Tell us what you’ve got: radiators, no ducts, a third floor that runs hot, an AC that quit. Ask for the arrival window then, so you’re not guessing around your commute on the Mass Pike or the Green Line. Estimates are no-cost.
The technician walks the house before talking equipment. That means the attic, the basement, how heat moves through the place, where an outdoor unit can sit on a tight lot, and where a refrigerant line could run without opening a wall. Then you get your options in plain language and in writing: repair or replace, central, zoned or ductless. If repair makes sense, that’s what you’ll hear.
Permits are part of the job in Newton. Inspectional Services at City Hall on Commonwealth Avenue handles them, and gas, plumbing and electrical work need a license copy and proof of insurance. Settle who’s handling that before work starts, and ask every contractor you’re comparing the same question.
Before install day, you and the crew agree on where the equipment goes and how floors and trim get protected. The system is tested before the crew leaves, and you get a walkthrough of the thermostat. After that, you hear from us again to make sure everything runs the way it should.

Residential air conditioning in Newton runs from a full central system to a single mini-split for a sunroom. We cover installation, repair and air conditioning maintenance services in Newton, MA, and we work on Trane, Carrier, Lennox, Goodman, Rheem, American Standard, York, Ruud, Amana and Bryant. You don’t have to be a past customer to call.
A spring visit means running the system and checking what tends to fail on its first hot day: refrigerant pressure, the condensate drain, the capacitor and contactor, the coils and the thermostat. Newton’s first heat wave often arrives in June, and the system that sat idle since September is usually the one that quits.
The Dempsey Comfort Club is our membership for scheduled maintenance and priority service. It suits an owner of a large older house in Newton Centre or Waban, and it suits a landlord with a two-family in Newtonville or Nonantum who can’t leave tenants waiting in a queue.
If you’ve ever searched for air conditioning services near you at 9 p.m. on a hot night, you know why we also offer 24/7 emergency service, with stocked trucks so more repairs get finished on the first visit. Financing for bigger replacements is available through Service Finance Company, LLC.
Often, yes, though not the way most people picture it. Central air means ducts, and a pre-1940 house heated by radiators has no obvious place for them. Sometimes there’s room in the attic for the upstairs, a basement run for the first floor, or a closet that can be given up. Sometimes there isn’t.
When ducts would mean opening plaster, a zoned system or ductless mini-splits are usually the better call. Many Newton owners have run window units for years while they sort this out, and that’s a fair stopgap. The walk-through tells you what’s realistic.
The technician looks at the framing, the floors, and where the outdoor unit can sit on your lot, then gives you the options in writing. If central air conditioning in Newton homes of this age isn’t a clean fit for yours, you’ll hear that before you hear a price.
Start with age and refrigerant. A well-maintained central system usually lasts 12 to 17 years, and many older units run on R-410A, while newer systems are moving to refrigerants like R-454B and R-32. Ask what yours uses and what a replacement would use.
Then look at what actually failed. A bad capacitor or contactor is a small repair on an otherwise healthy system. A failed compressor on a 16-year-old unit is a different conversation. Age alone shouldn’t make the call.
In a big older Newton house, there’s one more factor: the AC often ages next to a boiler or furnace of similar vintage. A repair that gets you through this summer, with a replacement planned for the off-season, can be a smart move. We’ll lay out repair and replacement options in writing, and if repair makes sense, we’ll say so. Air conditioning installation in Newton, MA shouldn’t feel like a rushed decision.
Newton’s fossil-fuel-free ordinance requires new buildings and major renovation projects to use electricity for heating and cooling, and the permit application has to say which systems you’re installing. The city’s climate plan counts about 1,500 heat pumps installed from 2019 to 2025, against a goal of roughly 6,000.
What a web page can’t tell you is where your project falls. The city decides what counts as a major renovation, and whether a replacement of an existing home’s AC is covered isn’t something to guess at. Tell us what you’re planning, and we’ll tell you what to confirm with Inspectional Services.
Heat pumps also cool, so they belong in the conversation either way. Mass Save changed its heat pump rebates for 2026 and dropped R-410A models from eligibility, so ask about the refrigerant in any system you’re quoted. Those rebates apply to heat pumps, not to standard central air alone. We install heat pumps and will show you both options, with no pressure to switch.
Once a year, in spring, before the first hot week. Newton’s first heat wave often lands in June, and it hit 101°F in June 2024. The city sees stretches of three or more days above 90°F a few times each summer. A system that’s been off since September is the one that fails on day one.
A proper visit means running the system and checking refrigerant pressure, the condensate drain, the capacitor and contactor, the coils and the thermostat. The drain matters in a multi-story house, since a clogged line can leak onto a finished ceiling below. Catching a weak part in April means a scheduled visit instead of a night without cooling.
If you’d rather not remember every spring, the Dempsey Comfort Club covers scheduled maintenance and priority service. Air conditioning maintenance services in Newton, MA make the most sense for the biggest, oldest houses and for two-family owners who answer to tenants.
Not one you can pick by square footage alone. Chestnut Hill and Newton Centre houses often have three floors, a finished attic, additions and a sunroom, and each one loads the system differently. A rule of thumb that works for a ranch will give you the wrong answer here.
Bigger isn’t better, either. An oversized unit cools the air fast, shuts off, leaves the house clammy, then starts again a few minutes later. That short-cycling wears out equipment and does a poor job with humidity. Sizing should come from the house’s actual heat load: windows, insulation, sun exposure, floors and how each room gets used.
For a big older house, the answer is often zones, so the third floor isn’t cooled by the first floor’s thermostat. Ask any contractor you’re comparing, us included, to explain how they landed on the size. A central AC system for a Newton home should also use matched indoor and outdoor components, since mismatched parts cut efficiency and can void warranties.
We offer financing through Service Finance Company, LLC, which helps when a large older house means a larger job. What you pay depends on the size of the house, how much duct work or zoning it needs, the efficiency level you choose and any rebates that apply to your equipment.
Offers change, and we’d rather quote what’s live today than what was live last spring. Ask about current heat pump offers when you call, and confirm the details before you decide. We don’t publish a price list, because two Newton houses on the same street can need very different systems.
Every estimate is no-cost, with the options in writing, so you can line it up against the others you’ll likely collect. When quotes from air conditioning services near you don’t match, the gap is usually size, ductwork or efficiency tier. Ask each contractor to show you which one it is.
