Weston’s own Hazard Mitigation Plan says the whole town is exposed to nor’easters, and it spells out the follow-on risk. When the power fails and the heat stops, water pipes can freeze and burst. The 2018 bomb cyclone left 420 Weston customers without power at one point. If you’ve sat through a night like that, you know the second problem often shows up after the lights come back.
The boiler locks out. One zone stays cold. The sump pump didn’t run, and there’s water where there shouldn’t be. Good HVAC repair in Weston, MA means someone looks at all of it, tells you what actually failed, and puts your options in writing before work starts. Because we handle heating, plumbing and sump pumps, that’s one call instead of three.
Summer is the other half. Many older oil-heated homes in Weston lack central air, and the town’s climate toolkit says summers here will feel closer to South Carolina’s by 2050. If you’re already facing a heating decision, ask whether a heat pump that cools too makes sense. Our heating and cooling services in Weston, MA cover both seasons in one conversation, and our HVAC maintenance services in Weston, MA keep the system ready before the next storm or heat wave.
Dempsey Energy is a family-owned, owner-operated company based in North Attleborough, and we’ve worked on Massachusetts homes for decades. Weston’s housing runs from Colonial and Federal-style buildings along North Avenue in the Kendal Green historic district, to Queen Anne homes around Silver Hill, to newer custom builds. Those homes don’t all need the same thing, and a residential HVAC contractor in Weston, MA shouldn’t treat them as if they do.
We work on oil, gas, boilers, furnaces, mini-splits and heat pumps, so our advice doesn’t depend on which fuel we happen to sell.
Most frustration with any HVAC company comes down to communication: not knowing what’s being done, why, or what happens next. Our technicians explain the concern before recommending a fix and tell you whether repair or replacement is the right next step. We track every job and follow up afterward, so you’re not left guessing.
If you’re searching for an HVAC contractor near you because the house is getting cold, start with the call. Tell us what’s happening: no heat, one zone dead, a strange noise after the power came back. Our trucks are fully stocked, which is why a lot of repairs get finished on the first visit.
When the technician arrives, they look at the whole system, not just the first thing that’s wrong. In a bigger house with more than one zone, or more than one boiler or furnace, that means checking each unit before saying which part failed. Then they explain what they found in plain language and whether repair or replacement makes more sense. You get your options in writing, and nothing starts until you say yes.
If the answer is a new boiler, furnace or heat pump, the paperwork matters. Weston Inspectional Services requires a mechanical permit for furnace, boiler and oil burner replacements, along with a gas or plumbing permit, and the town has an online Permit Portal. For HVAC installation in Weston, MA, we walk you through who’s handling the permit and when the inspection happens, so nothing catches you off guard. Check current requirements with the town, too.
After the work, we follow up. That’s also when we bring up maintenance, so the next cold snap isn’t the first time anyone looks at the system.

Most Weston homes run on a mix. Eversource supplies the electricity, National Grid supplies the natural gas, and plenty of houses still heat with oil or propane. As an HVAC company in Weston, MA, we work on all of it: furnaces, boilers, oil burners, oil tank replacement and removal, gas heaters, heat pumps, central air and ductless mini-splits. Thermostats, indoor air quality, water heaters, sump pumps, drains and electrical work are on the list too. That’s why one call can cover a restart, a frozen line and a wet basement, whether you’re on a quiet street off the Boston Post Road corridor or out near Kendal Green.
If a heat pump is on your mind, you’re not alone. Weston’s climate plan, Weston Ahead, sets goals around replacing fossil-fuel heating with heat pumps, and Mass Save’s current plan steers rebates toward electric heat pumps. Those are goals and program direction, not rules for your house. We lay out every option, including repairing what you have, and help you sort out what you may qualify for through Mass Save and the 0% HEAT Loan for up to $25,000. Select systems come with 10-year manufacturer and labor warranties.
Our HVAC maintenance services in Weston, MA run through the Dempsey Comfort Club, our membership program. Members get annual maintenance, priority scheduling, and discounts on parts, labor and repairs. If you live in one of the town’s historic areas, ask about permits and any historic-area rules before outdoor equipment goes in.
In most cases, yes. Weston Inspectional Services handles building, electrical, plumbing, mechanical and gas permits. The town’s mechanical permit checklist covers furnaces, boilers, oil burners and wood stoves. A replacement usually needs a gas or plumbing permit alongside the mechanical one, and the inspection has to be scheduled.
The town runs an online Permit Portal, and Inspectional Services is at 11 Town House Road (781-786-5040). Fees change, so check the current schedule with the town instead of trusting a number you find online. For HVAC installation in Weston, MA, settle one thing before you sign: who is pulling the permit, and who is scheduling the inspection? We’ll answer that question clearly. If your project includes new ductwork as part of an addition over 100 square feet, sheet metal gets inspected before the framing is closed in.
Start with age. Air conditioners and heat pumps tend to last 10 to 15 years, furnaces and boilers 15 to 20, and water heaters about 10. Once equipment is past those ranges, a failure is less a question of if than when.
Then look at the repair itself. If the fix is small and the system is mid-life, repair usually wins. If you’re being quoted a big repair on a boiler or furnace already near the end of its range, put that money toward comparing replacement options instead, especially heading into winter. Older equipment also costs more to run.
We explain whether repair or replacement is the right next step and put the options in writing so you can decide on your own timeline. For older homes in Weston’s historic districts, our HVAC maintenance services in Weston, MA are how you find out about a tired boiler in October instead of at 2 a.m.
Dempsey Energy doesn’t publish prices, because the number depends on your house. Here is what one 2026 Massachusetts cost guide shows as typical ranges. A full system replacement runs about $5,500 to $19,000. A gas furnace is roughly $3,500 to $8,500, central AC $4,500 to $10,500, and a ducted heat pump $7,000 to $16,000. The same guide says Greater Boston runs about 15 to 20 percent above the state average, which is the bracket Weston falls into.
What moves the number: system type, house size and layout, the condition of existing ductwork, whether a heat pump needs an electrical panel upgrade, the efficiency level you pick, permits, and rebate eligibility. Bigger homes with more than one zone simply involve more equipment.
For HVAC installation in Weston, MA, you’ll get a written quote after someone looks at the house. If financing helps, ask about the Mass Save HEAT Loan, which is 0% interest up to $25,000 for those who qualify.
It can, if it’s a cold-climate model and it’s sized properly. Cold-climate heat pumps are built for New England winters, but the word that matters is sized. That means a load calculation for your actual house, not a rule of thumb. Oversized units cycle on and off, and undersized ones struggle on the coldest days. Mass Save rebates also require a load calculation, plus qualifying equipment and a qualifying installer, so ask us whether you qualify before you assume.
The nor’easter question is different. A heat pump needs electricity, and so do most boilers and furnaces, since their controls and circulators run on power. Weston has had outages in big storms, so if backup heat matters to you, talk about it before anything gets removed. We’ll discuss keeping an existing system, adding a generator, or using propane. For an older oil-heated home in Weston, keeping the oil system as backup while a heat pump handles most of the year and adds air conditioning can be a reasonable middle path.
Start with the simple stuff. Make sure the thermostat is set to heat and the display is lit, since some need fresh batteries after an outage. Then check the breaker and the emergency switch on the furnace or boiler. If you heat with oil, confirm there’s fuel in the tank, and press the burner’s reset button once at most, because repeated presses can flood the burner. If you smell gas, leave the house and call 911 and National Grid from outside.
If it still won’t run, don’t wait long. In a cold house, pipes are the real clock, and Weston’s Hazard Mitigation Plan warns that heat loss can freeze and rupture water pipes. Open cabinet doors under sinks on exterior walls, let a faucet drip, and know where your main water shutoff is. If an outage drags on, the town’s emergency shelter is the Community Center at 20 Alphabet Lane. When you’re ready to call for HVAC repair in Weston, MA, tell us what you already checked. It speeds up the diagnosis.
We don’t run a discount just for Weston, and we don’t have group pricing like senior or military discounts. What dempseyenergy.com does list: $50 off any heating or cooling service, $50 off any plumbing service, and $500 off any new heating system installation, which is limited-time and can’t be combined with other offers. The heat pump page lists $500 off a new heat pump install. Offers change, so confirm which ones apply when you book.
The bigger savings for a Weston household tend to come from elsewhere. Many homes here have more than one system, and some are older, so the Dempsey Comfort Club tends to matter more over time than a one-time coupon. Members get annual maintenance, priority scheduling, and discounts on parts, labor and repairs. With the town and Mass Save both leaning toward heat pumps, it’s also worth asking whether you qualify for Mass Save rebates or the 0% HEAT Loan. Those come from the program, not from us, and eligibility rules apply. As an HVAC company in Weston, MA, we’ll tell you which applies to your situation.
