Heating & Cooling Services in Westport
Westport work leads with water heater, heat pump and boiler estimates, then cooling repair, oil tank questions and shore-property upkeep.
Water heater replacement
We replace tank, tankless and heat pump water heaters. Each replacement begins with a free written estimate.
Heat pump estimates
Westport farmhouses and added rooms often lack ducts, which suits a mini split heat pump. The free written estimate sizes the system to the rooms you use.
Boiler replacement
Older Westport houses commonly heat with oil boilers. A boiler past repair gets a free written estimate with the replacement options laid out.
Refrigerant system repair
In June 2026 we evaluated a Westport refrigerant system and made repairs. The first visit is a paid diagnostic, which shows whether the system is leaking and what the fix involves.
Oil tank replacement
Rural and shore properties here often burn oil, so see oil-to-gas conversions if a gas main reaches your road. Oil tank work starts with a free written estimate.
Maintenance for shore properties
Salt air and spray are hard on outdoor coils near the Westport River and the beaches. A seasonal visit cleans and inspects the outdoor unit.

Westport mixes working farms and large rural lots, older farmhouses, beach cottages and waterfront homes on the Westport River and the open water beyond it. Some shore properties are seasonal and sit empty for months. Salt air and spray are hard on outdoor coils and fittings near the water. Oil and propane heat many houses, and natural gas serves the rest where a main runs.

Along the river and the beaches, salt reaches coils and fittings and shortens their working life. We recommend a seasonal cleaning and inspection of the outdoor unit.
