Heating & Cooling Services in Wareham

Wareham work covers furnaces, boilers, central AC, heat pumps, mini splits and water heaters, plus ice machines for businesses.

Central AC repair

The April 2026 job replaced a gas furnace and AC in one project, and the July 2026 visit was routine AC maintenance. A central AC repair starts with a paid diagnostic visit.

Furnace repair

Each no-heat repair starts with a paid diagnostic visit. If the furnace cannot be repaired, see furnace installation and replacement.

Boiler repair and replacement

We removed an old Wareham boiler and installed its replacement in April 2025. Boiler replacements start with a free written estimate.

Mini split repair

In May 2026 we diagnosed a Fujitsu mini split with a communication failure and no power. Other Wareham repairs that month included a short and wiring fault in an indoor unit and a power board installation.

Heat pump water heaters

We installed a heat pump water heater in Wareham in October 2025. These units use less electricity than a standard electric tank and may qualify for rebates, so ask us to check the current terms.

Maintenance

Wareham maintenance includes the July 2026 AC visit. Call to schedule furnace or boiler service before the heating season and AC service before the cooling season.

Wareham Neighborhoods We Serve

We serve all of Wareham, including these areas:

Wareham Village, Onset, East Wareham and West Wareham
Swifts Beach, Little Harbor and Tihonet
the Buzzards Bay and Wareham River shore

Nearby towns we also serve: Mattapoisett, Rochester, Middleborough, Plymouth, Lakeville, Marion, and Carver.

What are Wareham homes like for heating and cooling?

Wareham mixes year-round homes with seasonal cottages near Onset Bay, Buzzards Bay and the Wareham River. Salt air is part of the equipment decision near the water, because it shortens the life of outdoor coils. Many homes burn oil or propane, because gas mains do not reach every street. Cottages and small capes often have no ductwork, which is where mini splits and heat pumps fit.

Which utility and rebate program applies in Wareham?

In Wareham the electric utility is Eversource, with gas available only where a main has been run. Mass Save, the program Eversource customers use, offers heat pump rebates and the 0% HEAT Loan to eligible customers. We review the current terms at the estimate rather than quoting amounts.

Commercial refrigeration in Wareham

Wareham businesses call us for walk-in coolers, reach-ins and ice machines. In June 2026 we adjusted and calibrated the ice thickness on a Wareham ice machine. Before you call, read the commercial refrigeration repair page for the equipment we cover and what to have ready.

Wareham Furnace, Boiler & AC Questions, Answered

My AC is not cooling in Wareham. What should I check first?

Look at the thermostat setting, the air filter and the breaker for the outdoor unit. If the outdoor unit is dead or the indoor coil is iced, turn the AC off and call 508-521-9477. Repairs start with a paid diagnostic visit.

My mini split shows a communication error or will not turn on. What does that mean?

A communication fault usually means the indoor and outdoor units are not talking, which points to a wiring, power or control board problem. A technician tests the power, the wiring and the boards. In May 2026 we diagnosed exactly that on a Wareham Fujitsu unit. See heat pump repair.

Can you replace a furnace and AC together in Wareham?

Yes. We replaced a Wareham gas furnace and AC together in April 2026, and one free written estimate can cover both systems. See HVAC replacement.

Do you service ice machines and coolers for Wareham businesses?

Yes. We service ice machines, walk-in coolers and reach-ins. Give the equipment type, the box temperature and your business name when you call 508-521-9477.

Is Mass Save available in Wareham?

Wareham is served by Eversource, so Mass Save applies to heat pump rebates and the 0% HEAT Loan. Ask for the current terms when we write the estimate.

How do I book a Wareham visit?

Call 508-521-9477 whenever you need us; it is answered 24/7. Prefer to type? Send the booking form, and we confirm the visit by text. Repairs begin with a paid diagnostic visit, while a replacement gets a free written estimate.
