AC repairs that restore comfort fast

Warm air from the vents, frozen coils, water around the air handler, short cycling, or a tripping breaker are signs your AC needs attention. Our technicians service all major brands, diagnose R 22 and R 410A systems, fix refrigerant leaks, clear condensate drains, and replace failed capacitors or fan motors. If the unit runs but the house will not cool, we find the root cause and share clear next steps.

AC installation and replacement with the right fit

Proper sizing and layout reduce noise, improve comfort, and save energy. We calculate cooling loads, review high efficiency options that meet SEER2 standards, and discuss budgets and timelines. Homes with existing ductwork can gain central air with a matched condenser and air handler. Older homes and additions often benefit from ductless solutions that place comfort where it is needed most.

Ductless mini split solutions for older homes

Mini splits are ideal where ducts are limited, like top floor bedrooms or sunrooms near Nagog Pond. Each indoor unit controls its own zone, which helps with hot rooms and reduces wasted energy. Many homeowners start with one zone and expand over time for year round comfort.

Brands and systems we service every day

Homes with propane heaters, oil boilers, hybrid furnace plus heat pump setups, and radiant systems are all within our wheelhouse. Tight basements and older chimneys around Acton Center are common and we design venting that fits those spaces.

Cooling maintenance for peak performance

A spring tune up keeps systems efficient through July and August. We check refrigerant charge, clean coils, clear drains, change filters, and verify thermostat calibration. After cooling season, ask about simple steps to winterize the outdoor unit so it is ready for next year.
