These are the towns closest to our New Rochelle shop, so they’re usually our fastest response times.
📍
New Rochelle is home. Our team lives and works here, and we know its mix of older colonials, multi-family homes, and waterfront properties. Many still heat with original boilers, so we spend a lot of time keeping those running and helping owners plan replacements before they fail in January.
📍
Pelham’s older homes often have tight mechanical spaces and original radiator heat. We repair and replace boilers and add ductless mini-splits for cooling without tearing into plaster walls.
📍
Larchmont homeowners count on us for boiler service, AC tune-ups, and standby generators. Storms along the Sound can knock out power, and a backup generator keeps the heat on when the grid doesn’t.
📍
From the harbor to the village center, Mamaroneck homes deal with coastal storms and humid summers. We handle emergency heating and cooling repairs, system replacements, and generator installs for homes that can’t afford to lose power.
📍
Harrison families call us for everything from no-heat emergencies to full system upgrades. Larger homes here often run more than one system or zone, and we service and replace multi-zone setups.
📍
Rye Brook homes need dependable heating and cooling year-round. We install and service furnaces, AC systems, and heat pumps, and our membership keeps them tuned before each season.
📍
White Plains has everything from downtown condos to single-family homes in quieter neighborhoods. We handle AC and furnace repair, boiler service, and new installations for homeowners and light commercial properties across the city.
📍
Many Scarsdale homes are older Tudors and colonials with boilers and zoned systems that need someone who knows them. We repair and replace boilers, install high-efficiency equipment, and handle the kind of work these homes call for.
📍
Bronxville’s prewar homes and co-ops come with heating systems that have been around for decades. We keep boilers and steam systems running and recommend upgrades when repairs stop making sense.
📍
Eastchester homeowners and local businesses call us for 24/7 heating and cooling repairs, seasonal maintenance, and system replacements. We also service light commercial buildings and storefronts.
📍
Hartsdale has a mix of single-family homes and apartment buildings. We service both, from individual furnaces and AC systems to heating systems in multi-unit properties.
📍
Valhalla residents rely on us for furnace and AC service, boiler repairs, and maintenance that keeps systems efficient through long Westchester winters.
📍
Irvington’s historic homes along the Hudson often need careful work: older boilers, limited duct space, and systems that have to fit the house instead of the other way around. We repair, replace, and add ductless cooling where ductwork isn’t practical.
Every town on this page gets the same technicians, the same transparent pricing, and the same 24/7 availability:
Two tune-ups a year, priority service, and 10% off repairs.
Westchester winters are long, and a lot of the housing here was built before modern HVAC. That means steam and hot-water boilers, oil systems, tight basements, and homes with little room for ductwork. Summers turn humid, and coastal storms can take out power for days. A team that has worked in these homes since 1980 knows how to keep older systems running, when to replace them, and how to size new equipment for the house you actually have.
We serve Westchester County, NY, including New Rochelle, White Plains, Scarsdale, Bronxville, Eastchester, Harrison, Pelham, Rye Brook, Irvington, Mamaroneck, Valhalla, Hartsdale, and Larchmont.
