What We Do
The same company that installs your system services it. This is the work we do every day.
Bellingham Heating Contractor
Furnaces, boilers, and oil heat are the core of our winter work: repairs, replacements, and annual tune-ups on gas and oil systems alike. Paul has worked on oil heat for over 30 years, so oil burner cleanings, Roth-certified oil tank replacements, and oil-to-gas conversions are everyday jobs for us. See everything we do on the heating services page, or call for a straight answer on whether your system is worth fixing.
Air Conditioning Contractor
We install and replace central air systems across MetroWest, and we put in a lot of ductless mini-splits. They suit the older homes around Franklin and Milford that were built without ductwork, and they heat as well as cool. System replacements start with a free estimate and honest sizing for your actual house. Compare your options on the air conditioning page.
Furnace Repair Service
No-heat calls come first in a New England winter. We diagnose and repair gas and oil furnaces of every brand, and our vans carry the common parts, so most repairs are finished in one visit. When a repair no longer makes sense on an older unit, we tell you and price the replacement honestly. Read what a furnace repair visit covers before you call.
Air Conditioning Repair Service
When the AC quits during a July heat wave, we move fast: same-day service whenever the schedule allows, on all makes and models. Plenty of "dead" systems just need a capacitor or a good cleaning, and we fix those on the spot rather than quoting a new unit. Our AC repair page covers the most common failures we see.
Boiler Installation & Repair
Baseboard and radiator heat runs on a boiler, and we work on all of them: gas and oil, hot water and steam. We handle emergency repairs, annual cleanings, and full replacements when an old boiler has run its course, and we supply and install the new equipment ourselves. Start with the boiler repair page, or ask about replacement options if yours is past twenty years.
Proudly Serving MetroWest Massachusetts
Based in Bellingham, we provide reliable heating and air conditioning services to homes and businesses across 24 communities in MetroWest and the Blackstone Valley.
What Our Customers Say
“Another company quoted $10,000 to replace our furnace. Paul came by that afternoon, found debris causing the motor to seize, removed it, and our heat turned on. He only charged us $99. Friendly, honest, and very knowledgeable.”
— Hannah B. · Yelp

“I've used him twice and both times he showed up within an hour of calling. We didn't have heat and he got it up and working in under an hour! So thankful he was able to get it done right away since the next few days were very cold.”
— Ali C. · Google
“I was told by three other companies that my 20+ year old AC unit needed to be replaced. Paul came out the next day, found that a few parts needed replacing, turned on the unit and it has been working ever since. I will never go to another company.”
— Carol S. · Facebook
“Our AC stopped working and Paul responded immediately. He was thorough, detailed, and professional. As first-time homeowners, he was very patient in teaching us how to take care of our HVAC. His prices are very reasonable.”
