Heating & Cooling Services in Plymouth
Plymouth work runs from heating pipe and no-heat repairs to cooling leaks, business refrigeration and replacement estimates.
Boiler and heating pipe repair
In August 2026 we repaired a leaking heating pipe in Plymouth. A leak in a hot water heating loop can drop the system’s pressure and stop the heat, so call before the boiler runs dry.
Furnace repair
A no-heat repair always starts with a paid diagnostic visit. If the furnace is past saving, the free written estimate comes first.
Cooling repair and leak search
In June 2026 we searched a Plymouth cooling system for a refrigerant leak with UV dye and recharged it. A system that keeps losing refrigerant has a leak, and finding it comes before adding more.
Commercial refrigeration repair
In July 2026 we evaluated a Plymouth refrigeration rack and its energy management system on an emergency call. The commercial refrigeration page lists the equipment we cover.
Maintenance
Plymouth is a big town, and our June 2025 maintenance visit there was on a heating and cooling system. Booking tune-ups ahead lets us choose a day that suits both of us.
Replacement estimates
Ask for an estimate and the written estimate follows the visit. A Plymouth replacement estimate is free.

Nearby towns we also serve: Duxbury, Wareham, Middleborough, Lakeville, Kingston, and Carver.
What are Plymouth homes like for heating and cooling?
Plymouth ranges from historic houses near the waterfront to 1970s capes, newer subdivisions and age-restricted communities such as The Pinehills. Seaside neighborhoods like Manomet and White Horse Beach have many cottages that now serve as year-round homes. Oil, propane and natural gas all heat Plymouth homes, depending on whether a main reaches the street. Houses with radiators or baseboard have no ducts for cooling, so a mini split or heat pump is the usual way to add it.
Which utility and rebate program applies in Plymouth?
Eversource supplies Plymouth’s electricity, with gas on streets where a main runs. The Mass Save programs for Eversource customers include heat pump rebates and the 0% HEAT Loan. We go through the terms in effect at the estimate.
Commercial refrigeration in Plymouth
We cover commercial refrigeration in Plymouth: call 508-521-9477 to arrange a visit. In July 2026 we evaluated a Plymouth refrigeration rack and its energy management system on an emergency call. Before you call, the commercial refrigeration repair page shows what we service.

Can you find the leak in my Plymouth air conditioner?
Yes. In June 2026 we used UV dye to search a Plymouth cooling system for a refrigerant leak before recharging it. The first visit is a paid diagnostic, and the repair is quoted after the leak is found.
Do you work on commercial refrigeration in Plymouth?
Yes. In July 2026 we evaluated a refrigeration rack and its energy management system on an emergency call. Equipment types and what to have ready are on the commercial refrigeration repair page.
Does Plymouth get Mass Save rebates?
