HVAC Contractor
in Greenwich, Connecticut

Greenwich has some of the most diverse HVAC conditions in Fairfield County. Old Greenwich and Riverside homes sit close to Long Island Sound, where coastal humidity and salt air exposure demand equipment that's properly specified for the environment. A standard residential condenser installed 200 yards from the water without a protective coating is a premature replacement waiting to happen. We spec coastal-rated equipment on every waterfront and near-waterfront property.

Backcountry Greenwich — the inland estates north of the Merritt Parkway — runs several degrees colder in winter than the shoreline neighborhoods. These homes often have large square footage, complex multi-zone systems, and high-end equipment that requires technicians who can work on premium brands and integrate with home automation systems. We've replaced boilers, installed whole-home heat pump systems, and commissioned multi-zone VRF-style ductless systems in Backcountry properties.

Cos Cob and Glenville have a mix of older homes built before central AC was standard — ideal candidates for ductless mini-split installation where running new ductwork would be invasive and expensive. We've done dozens of these conversions in Greenwich and can assess whether a ductless system makes sense for your home's layout.

From Backcountry estates to Old Greenwich colonials, Cos Cob ranches to Riverside waterfront — Airmax serves all of Greenwich with discretion and precision.

Seasonal note: Greenwich's proximity to Long Island Sound moderates temperatures along the shoreline, but Backcountry properties can see heating degree days comparable to inland Fairfield County. We size systems for the actual location, not the average.
