HVAC & Plumbing Services in Wellesley, MA
A Big Old House That Finally Heats Evenly
Your home is supposed to take care of you, not the other way around. When the boiler quits on a January night off Washington Street, or the third floor never cools in July, one phone call puts a licensed technician on the way from our Newton shop, ten minutes up Route 9.
Tell us what is going on at your Wellesley home. We will call you back with a real time slot, not a two week window.

Air Conditioning in Wellesley, MA
Wellesley is a town of single family houses, and about a third of them were built before 1940. Cooling a house like that is mostly a question of where the equipment can go, so we start by walking the house with you.
AC Installation & Replacement
Every Wellesley home is different. We measure yours first, then help you pick the system that fits it, whether that is central air on your existing ducts or a ductless heat pump for a house that never had them. On a big center entrance colonial that usually means zoning the upper floor separately, so it is not ten degrees warmer than the first.
- Central air systems
- Ductless mini splits for homes with no ductwork
- High velocity small duct for pre-war homes
- Cold climate heat pumps that heat and cool
- Load calculation on every quote
- Permits pulled and inspection scheduled
AC Repair
When your AC stops working on a hot day, you need help fast. Our shop sits just over the Newton line, so we offer same day visits when we can, and you can reach us any time, day or night.
- System not cooling or blowing warm
- Ice on the refrigerant lines
- Water pooling around the air handler
- Breaker tripping or unit not starting
- Short cycling and weak airflow
- All major brands serviced
AC Maintenance & Tune-Ups
We check your AC each spring, before the first hot week. A yearly visit helps catch small problems early, keeps your warranty in good standing, and gives us a look at the outdoor unit after a long Wellesley winter.
- Coil clean and inspection
- Refrigerant charge check
- Capacitor and electrical test
- Condensate drain cleared
- Thermostat calibration
- Written report every visit

Heating in Wellesley, MA
About seven in ten Wellesley homes heat with natural gas, and roughly one in seven still runs on oil. Boilers, furnaces, radiators or heat pumps, we work on all of it.
Heating Installation & Replacement
A new system should fit your home, not just match the old one. We look at your house first, then help you pick the right size so it heats evenly all winter. In an older Wellesley house we look at the radiators and piping too, because a new boiler on a tired distribution system still leaves cold rooms.
- Gas furnaces
- Steam and hot water boilers
- Oil to gas conversions
- Cold climate heat pumps
- Radiant and ductless systems
- Old equipment removed, permits handled
Heating & Furnace Repair
A cold house can’t wait. When your heat stops working, we come over from Newton and get it running again. Our team is ready all winter long, even in the middle of the night.
- No heat calls, 24/7
- Ignition and pilot failures
- Thermostat and control faults
- Circulator pump failure
- Boiler pressure loss
- Frozen condensate lines
Heating Maintenance & Tune-Ups
An early fall tune-up, before the first cold night in Wellesley, with a full combustion analysis and a carbon monoxide safety check on every gas and oil system we service.
- Combustion analysis
- Carbon monoxide test
- Heat exchanger inspection
- Burner clean and adjust
- Safety control test
- Flue and venting check
No heat in Wellesley?
24/7 no heat calls all winter. Free estimates on replacements.
Plumbing in Wellesley, MA
Need a plumber in Wellesley? The same company that handles your heating handles your water, so one visit can cover the boiler or furnace, the water heater and the pipes between them.
Tanked & Tankless Water Heaters
Navien and Rinnai installation and replacement, including the gas line, venting and condensate work that goes with it. In an older Wellesley house the venting run and the gas line sizing usually decide whether tankless makes sense, so we look at both before we quote.
- Navien, Rinnai and Rheem
- Gas line sizing and upgrades
- Venting and condensate routing
- Tank to tankless conversions
- Descaling and annual service
- Permits pulled
Kitchen & Bathroom Plumbing
Fixtures, toilets, sinks, dishwasher lines and remodel rough-ins, quoted upfront before the work starts. Wellesley is an MWRA sewer community, and in houses this old we check the supply and drain lines before we add anything new.
- Faucet and fixture installation
- Toilets, showers, tubs and vanities
- Garbage disposals
- Dishwasher and ice maker lines
- Remodel rough-in
- Leak and drain repair
Plumbing problem in Wellesley?
Upfront quotes before the work starts. Active leaks go to the emergency line.
Electrical and Indoor Air Quality in Wellesley, MA
Panel space and air quality are the two questions that come up right after a heat pump quote. Our own licensed electricians handle the panel in-house, so you don’t have to find a second contractor.
Electrical Service & Panel Upgrades
Panel upgrades for heat pump and whole-home AC conversions, plus general electrical service, done by our own licensed electricians. Older Wellesley houses often need the service upgraded before heat pumps go in, so we check the panel before you commit to new equipment.
- 100 amp to 200 amp upgrades
- Dedicated HVAC circuits
- EV charger circuits
- Outlets, switches and lighting
- Code corrections
- Permits and inspection handled
Indoor Air Quality
Filtration, ventilation and humidity control planned alongside the equipment instead of added on later. In a pre-war Wellesley house that usually means dealing with dry winter air and a damp basement in the same plan.
- Whole-home air filtration
- UV purification
- Humidifiers and dehumidifiers
- Fresh air ventilation
- Duct sealing and repair
- Allergy and mold concerns
Planning a heat pump conversion?
We quote the panel upgrade and the equipment together, on one estimate.

Rebates and financing
Wellesley gets its electricity from the Wellesley Municipal Light Plant rather than an investor-owned utility, so electric incentives here run through the town’s own programs rather than Mass Save. Gas equipment may still qualify through your gas utility, and we run 0% promotional financing on installs. We check what actually applies to your house before you commit.

Wellesley HVAC and plumbing questions
Wellesley is one of the closest towns to our Newton shop, about ten minutes on Route 9 or Route 16 outside of rush hour. For no heat, no cooling, or an active leak, call the emergency line at (508) 470-4590. We run that line around the clock, and during the heating season we staff it heavily because December through February is our busiest stretch.
Yes for most replacement and installation work. The Town of Wellesley issues building, plumbing, gas and electrical permits, and a single heating replacement often needs more than one of them. Massachusetts requires a licensed contractor to pull those permits, not the homeowner. We file them, schedule the inspection, and see it through to sign-off.
It depends on the fuel, the system type, how much of the existing ductwork or piping can be reused, and how much access the basement gives us. A gas furnace swap with sound ductwork sits at the low end. A boiler replacement in a large older house sits higher, and a full heat pump conversion is higher still. We quote the actual job after seeing the actual basement, and we give you the number in writing before any work starts.
Yes, and it is the most common question we get here. Ductless mini splits are usually the answer: one outdoor unit feeding indoor heads in the rooms that matter, with no soffits and no lost closet space. High velocity small duct systems are the other option when you want the look of central air and have some chase space to work with. Both cool in summer, and heat pump versions heat in winter too.
This is where Wellesley differs from its neighbors. The town runs its own Municipal Light Plant instead of buying electricity from an investor-owned utility, and Mass Save is funded by investor-owned utility ratepayers, so the usual Mass Save electric rebates and the 0% HEAT Loan do not work the same way here. The Light Plant runs its own efficiency offers, and gas equipment may still qualify through your gas utility. We check what is actually available for your address before you commit, and we offer 0% promotional financing on installs either way.
Regularly. About a third of Wellesley’s housing predates 1940, and those houses have their own habits: long pipe runs, converted attics, additions on additions, and a top floor that never matches the rest of the house. We size room by room rather than by square footage, and we zone where zoning is the honest fix.
All of it. Wellesley Square, Wellesley Hills, Wellesley Farms, Babson Park, the Country Club area and everything off Route 9, Route 16 and Route 135. ZIP codes 02481, 02482 and 02457. You can see the rest of our coverage on our service area page.
All of it, under one company. Heating and cooling, kitchen and bathroom plumbing, tankless water heaters, electrical service and panel upgrades, and indoor air quality. That matters most on bigger jobs: a heat pump conversion in an older Wellesley house often needs a panel upgrade, and coordinating that yourself across two contractors is where projects stall.
