We Leave Our Customers Smiling

Ask three neighbors in Hopkinton what heats their house and you could hear oil, gas, and propane. The town covers about 28 square miles of village centers, lake areas, and farm roads, and what’s available on one street isn’t guaranteed on the next. That’s why we start with your address, not a standard recommendation.
Once that’s sorted, you know where you stand. Maybe gas conversion makes sense at your house. Maybe a cold-climate heat pump is the better fit, especially if you’re leaving oil and want cooling in the same system. Or maybe the boiler you have deserves a few more winters.
If you live in an older house near the Town Common or in Woodville’s historic section, the payoff looks different. Homes like those tend to have boilers with baseboard or radiators and no ductwork, so a ductless system can add cooling for July without opening up plaster. You end up with a house that handles January lows near 15°F and humid summer stretches without a major remodel.
That’s what HVAC installation in Hopkinton, MA looks like when it’s done right: a plan matched to your house, with a written scope you can read before anything starts.
Dempsey Energy is a family-owned, owner-operated company that handles heating, cooling, plumbing, and electrical for Massachusetts homeowners. Thousands of customers have called us, and we’ve learned that people rarely remember the repair itself. They remember whether someone explained it, showed up when they said they would, and checked in afterward.
So that’s how we run things. Every job is tracked, every customer gets a follow-up, and the technician in your basement tells you what they found in plain terms before suggesting anything.
In Hopkinton, that covers a wide range of houses. You’ve got boilers in the period homes along Wood Street in Woodville, oil systems and gas furnaces around town, and newer subdivisions like Legacy Farms where systems are aging. The approach is the same for each. HVAC repair, replacements, conversions, and tune-ups in Hopkinton all start with a conversation, not a sales script.
The first call is simple. Maybe you went looking for an HVAC contractor near you at 9 p.m. with no heat, or maybe you’ve been planning a replacement for months. Either way, tell us what you’re seeing. Our trucks are fully stocked, so many repairs get finished on the first visit.
On site, our technician diagnoses before recommending anything. You’ll hear what failed, what the repair involves, and whether repair or replacement is the better next step. If replacement is on the table, we look at what you heat with now, whether gas is an option on your street, the condition of any ductwork, and your electrical panel. Heat pump sizing comes from a load calculation, not a guess.
Then you get your options in writing, with scope, price, and what’s covered. Nothing starts until you approve it. Any work that needs a permit goes through Hopkinton’s Inspectional Services, which handles building, gas and plumbing, and wiring. Electrical work needs its permit before it begins, with a short allowance for true emergencies. We handle that paperwork, and you’ll hear from us after the job is done.
If you’re planning an install, April and early fall are easy windows. Marathon Monday closes Main Street and the Town Common area, so mention it if you’re booking around then. Our crews plan around local events in Hopkinton.

Your visit can be a repair, a tune-up, or a full swap, and it’s the same crew either way. We work on oil burners and tanks, gas heat, boilers, furnaces, central AC, ductless mini-splits, and heat pumps. We also handle plumbing and electrical when a problem crosses over. That matters in Hopkinton, where one house may run an oil boiler and the one next door a gas furnace.
For heating and cooling services in Hopkinton’s older homes, the job is often keeping a boiler healthy and adding a mini-split for summer. In many newer subdivisions, systems from the past couple of decades are reaching the age where furnaces typically run 15 to 20 years and AC units 10 to 15. Control boards, inducer motors, and condensate problems tend to show up quietly, so we show you the failed part and explain your choices. HVAC repair shouldn’t feel like guesswork.
The Dempsey Comfort Club is our membership plan. It includes an annual maintenance visit, priority scheduling, and member discounts on parts, labor, and repairs. It makes sense for larger homes where a January failure is expensive and disruptive. Select new systems also carry 10-year manufacturer and labor warranties, so ask which ones qualify. We’ll also walk you through Mass Save rebates and the 0% HEAT Loan.
There isn’t one answer for the whole town. Gas availability is street by street in Hopkinton, so the first step for any HVAC installation is finding out whether a gas main runs past your property. Your gas utility can tell you that. Once you know, we can explain what a conversion involves: bringing the line in, installing new equipment, and removing the old oil tank.
If gas isn’t available, or the numbers don’t work, a cold-climate heat pump is the usual alternative. For oil-heated homes in Hopkinton that never had central air, it also adds cooling. Some homeowners keep an existing boiler running while they plan. We’ll lay out each path in writing so you can compare them side by side instead of guessing.
Yes, when they’re true cold-climate models and they’re sized properly. Hopkinton sees January lows around 15°F and regular snow, which is the kind of weather these systems are built for. Sizing is where things go wrong. An undersized system struggles in a cold snap, and an oversized one short-cycles. We run a load calculation for your specific house instead of guessing from square footage.
In older Hopkinton homes with limited insulation, the answer may be a heat pump handling most of the heating with your existing boiler as backup. Or it may be a partial install covering the rooms you use most. Mass Save rebates also require that load calculation, so doing it right helps twice.
Start with age. Furnaces and boilers usually last 15 to 20 years, and AC units and heat pumps 10 to 15. If yours is inside that window and the problem is one inexpensive part, repair usually wins. If it’s near the end of its range and you’ve had a second major repair in a couple of seasons, replacement starts to make more sense.
Many Hopkinton homes in newer subdivisions are now in that gray zone. The failures tend to be control boards, inducer motors, and condensate drains rather than anything you can see. When you call for HVAC repair, ask the technician to show you the failed part and explain what happens if you skip the repair. You should never feel pushed to replace a system on the first visit.
Published statewide estimates for Massachusetts put a full system replacement anywhere from $5,500 to $19,000. By type, a gas furnace runs about $3,500 to $8,500, central AC $4,500 to $10,500, and a ducted heat pump $7,000 to $16,000. Those are third-party 2026 estimates, not a Dempsey Energy quote, so use them to understand what’s normal.
What moves your number is the system type, the size and layout of your house, ductwork condition, whether a heat pump needs an electrical panel upgrade, the efficiency level, permits, and rebates. Larger Hopkinton homes with multiple zones tend to land higher in any range. A written quote after a visit is the only way to get a real figure. The 0% Mass Save HEAT Loan, up to $25,000 for those who qualify, can help spread the cost out.
A proper tune-up checks the equipment that can fail or turn unsafe: the burner or heat source, safety controls, filters, thermostat, and for AC, the coils and condensate drain. Our technician documents what they found and tells you what’s urgent and what can wait. If someone hands you a long list with no explanation, ask questions.
Timing matters. Book boiler and furnace service in early fall before the first real cold snap, and AC service in spring before June humidity arrives. Most manufacturers also require annual maintenance to keep warranty coverage. For HVAC maintenance services in Hopkinton, the Dempsey Comfort Club bundles the yearly visit with priority scheduling and member discounts on parts and labor, which makes sense for larger homes.
We don’t offer Hopkinton-only discounts or special group pricing, so we won’t make one up. What does exist is more useful for oil-heated homes. We post coupons on our site, such as $50 off any heating or cooling service, $500 off a new heating system installation, and $500 off a new heat pump install. They’re limited-time and can’t be combined, so check the coupons page for what’s current.
The bigger savings usually come from Mass Save. Switching from oil to a heat pump is one of the most common upgrades in Massachusetts, and rebates and the 0% HEAT Loan, up to $25,000, exist for exactly that. Eligibility depends on your home and equipment. Ask us whether you qualify before you sign anything, and we’ll help with the paperwork.
