Most heating failures in Holliston don’t wait for a convenient time. The boiler quits at 10 a.m., the house sits empty all day, and you find out at 6 p.m. when you walk in the door. Holliston is mostly a bedroom town, so a lot of households spend the workday somewhere else, with Route 16 and Route 126 as the way out and the way back.
A good HVAC contractor in Holliston shortens that evening. With HVAC repair from Dempsey Energy, you get a same-day appointment when the schedule allows, a tech who tells you in plain terms what failed, and a truck stocked with common parts. Many repairs wrap up on the first visit instead of costing you a second day off work.
You also stay in the loop. You hear what was found, what the fix costs, and whether repair or replacement makes sense before anyone picks up a tool. Afterward we follow up, so you’re not wondering whether it held while you’re back at your desk.
The other local piece is the houses. A large share of Holliston homes were built before 1970, which means original boilers, oil burners and duct runs that have been patched over the years. If you’re in Mudville or Braggville, knowing what’s actually in your basement, and what’s realistic to do about it, takes the guesswork out of what comes next.
Dempsey Energy is a family-owned, owner-operated HVAC company serving Holliston homeowners. We work out of North Attleborough, not a Holliston storefront, and we’d rather say so than pretend otherwise. We’re also not going to claim to be the oldest name in town. There are good local shops here, and you should compare.
What we ask is that you compare how each one explains things. Ours is simple. We listen to the concern, explain what your home may need, and tell you whether repair or replacement is the right next step. Then you decide. We track every job and follow up afterward, and thousands of customers have been through that process.
As a residential HVAC contractor in Holliston, you’ll see everything from antique colonials near the town green to ranches and executive subdivisions like The Queens and Willowgate Rise. We work on oil, gas, boilers, furnaces, mini-splits and heat pumps, with plumbing and electrical under the same roof. One call covers whatever is in your basement.
It starts with a call. Tell us what the system is doing, what fuel it runs on, and when someone can be home, and we’ll build the visit around your day. If the heat is out, say so up front.
The tech’s first job is figuring out what’s wrong, not what to sell. You get the explanation in plain terms, then your options: repair, replace, or wait with a plan. Nothing starts until you’ve agreed to a written scope and price. Surprise bills and silence are the two biggest complaints people have about HVAC companies, and both come from skipping this step.
For HVAC installation in Holliston, the size of the new system should come from a load calculation on your actual house, not from whatever was there before. Gas, plumbing and electrical work here goes through the Building Department at 703 Washington Street, and a contractor has to show a license and insurance to pull a permit. Ask who’s pulling it and get that in writing.
Timing matters too. Holliston’s cold season runs roughly early December to mid-March, so fall is the easiest window for planned replacements and heat pump conversions. If a Mass Save rebate might apply, we sort out whether you qualify before the install, not after. When the work is done, we follow up to make sure everything is running right.

Heating and cooling services in Holliston from Dempsey Energy cover furnaces, boilers, oil burners and oil tank replacement, central AC, mini-splits, heat pumps and thermostats. Plumbing and electrical are on the same phone number when a job crosses over.
In Holliston Center and Mudville, where antique colonials can be hard to duct, ductless mini-splits and heat pumps are worth a look for adding cooling without opening up plaster. In newer subdivisions with ductwork already in place, a ducted replacement is often the better fit.
The Dempsey Comfort Club is how we handle HVAC maintenance services in Holliston. Members get an annual maintenance visit, priority scheduling, and discounts on parts, labor and repairs. If you just bought a house and nobody can tell you how old the system is, that first visit gives you a baseline before the cold season arrives.
If a replacement is on the table, financing is available. The Mass Save HEAT Loan offers 0% interest on up to $25,000 for eligible projects. Rebates depend on the equipment, the installer and your home, so ask us whether you qualify before you buy anything. And if you searched for an HVAC contractor near you because something just failed, call first and describe the symptoms. A few minutes on the phone often tells us what to bring.
Start with age, then the repair quote, then how the system has been behaving. Furnaces and boilers typically last 15 to 20 years, and AC units and heat pumps 10 to 15. If yours is near the end of that range and the repair costs a big share of a new system, it usually isn’t worth fixing. A newer unit with one failed part usually is.
Holliston has a lot of homes built before 1970, so a boiler nobody can date isn’t unusual here. Find the model and age on the data plate and bring it up on the call. When you book HVAC repair in Holliston with Dempsey Energy, the tech will explain what failed and whether repair or replacement is the right next step, and you decide. There’s no pressure on the first visit. Heading into December on a 20-year-old boiler is a bet, so it’s worth knowing the odds.
Dempsey Energy doesn’t publish prices, because the number depends on your house. These are statewide third-party estimates, not a quote. Full system replacement in Massachusetts runs about $5,500 to $19,000. Within that, a gas furnace is roughly $3,500 to $8,500, central AC about $4,500 to $10,500, and a single-zone mini-split about $3,500 to $9,000.
What moves the number is fuel type, house size and layout, the condition of your ductwork, whether a heat pump needs an electrical panel upgrade, efficiency level, permits and rebates. Holliston ranges from small capes to large executive homes, so the spread here is real. For HVAC installation in Holliston, you’ll get a written scope and price before work starts. Compare it against two other quotes, and compare what each one explains, not just the total.
Yes, if it’s a cold-climate model and it’s sized correctly. Holliston’s cold season runs roughly early December to mid-March, with average highs below 44°F, and that’s well within what these systems are built for. Sizing is where jobs go wrong. It should come from a load calculation of your house, not a rule of thumb, because an oversized unit short-cycles and wears out sooner.
In a colonial with no ducts, mini-splits put heating and cooling in the rooms you use without opening walls. Some homeowners keep their existing system for the coldest stretches, and we’ll tell you honestly whether that makes sense for yours. Oil-heated homes often have no central AC, so a heat pump adds cooling too. Mass Save rebates require qualifying equipment and an installer in their network, so ask us whether you qualify.
If you can, check the basics from your phone. Look at the thermostat settings and batteries, and the breaker. If you heat with oil, check the tank gauge. Don’t keep hitting the reset button on a burner that won’t stay lit. Then call and tell us what the system is doing and what fuel it runs on.
If the house will sit empty for hours in January, mention it. A house that drops far below normal can put pipes at risk, and we handle plumbing too. We’ll work out access with you, whether that’s someone at home, a neighbor, or a time you can get there, so you aren’t forced to pick between a day off and a cold night. Our trucks are stocked, so many repairs finish in one visit. On storm days getting anywhere in Holliston takes longer, so call early. HVAC repair in Holliston goes faster when we know the symptoms before we show up.
It depends on your system’s age and how much you want to leave to chance. The Dempsey Comfort Club includes an annual maintenance visit, priority scheduling, and member discounts on parts, labor and repairs. We haven’t posted a membership price here, so ask when you call and judge it on the real number.
The case for it is practical. Most manufacturers require annual maintenance to keep warranty coverage. A boiler or furnace in a pre-1970 Holliston house benefits from a yearly look before the cold season. And priority scheduling matters most on the one January morning when everybody is calling. It’s a weaker fit if your system is brand new and you already have a tech you trust. Either way, HVAC maintenance services in Holliston should leave you with something in hand: what was checked, what was found, and what to watch next year.
There’s no Holliston-only discount, but there are real ones you can use here. The website lists $50 off any heating or cooling service and $50 off any plumbing service. For a limited time, it also lists $500 off a new heating system installation. That offer can’t be combined with others, so confirm the current terms when you call. Comfort Club members also get discounts on parts, labor and repairs.
For most households in Holliston, the discounts that matter are on the big jobs. Many Holliston homes were built before 1970, and plenty are still on a boiler or furnace they’ve had for decades. When one of those fails, the replacement is a large bill no matter what the house is worth. That’s where the install coupon, the Mass Save HEAT Loan at 0% interest on up to $25,000, and any rebates you qualify for add up. An HVAC contractor in Holliston should help you sort through all of it, and we will.
