One county, and just about every heating and cooling system ever installed in the Northeast. Carey & Walsh has covered Westchester from Briarcliff Manor since 1944 — steam and hot water, oil and gas, ductless and forced air, with 24/7 emergency response across the whole county.
Westchester is unusually varied for a single county, and it shows in the mechanical rooms. The river towns and older villages — Tarrytown, Ossining, Peekskill, Peekskill — hold a great deal of century-old housing still running steam or hot-water heat through original cast-iron radiation. White Plains adds dense downtown condos and co-ops where ductwork was never an option and ductless does the work. Scarsdale and Bronxville are full of 1920s Tudors with plaster walls and no duct chases. Push north into Cortlandt, Chappaqua and Yorktown and natural gas stops reaching every road, so oil-fired equipment is still common. Very few contractors work comfortably across all of that. We have been doing it for eighty years.
Riverfront villages like Westchester County also see their own weather pattern — humid, sticky summers off the Hudson and damp, raw winters that are hard on aging heating equipment. Between the older housing stock and the local climate, Westchester County homeowners deal with a particular set of HVAC challenges that a contractor unfamiliar with the area can easily get wrong. We've been working in Westchester's river towns since 1944, and our technicians know what to expect before they ring the doorbell — whether that's a cramped basement boiler room in a pre-war home near the village center or a modern forced-air system in a newer build closer to the Saw Mill River Parkway.
Furnaces, steam boilers, hot-water boilers, oil burners, heat pumps and ductless heating — repaired, maintained and replaced across the entire county. Including the steam and oil equipment many contractors have quietly stopped servicing.
Central air where ductwork exists or can be run — we fabricate our own sheet metal, which makes retrofits possible in houses where standard sizes do not fit. Ductless mini-splits everywhere else. Mitsubishi Diamond Contractor.
The most common heating system in Westchester County's newer construction. We repair, maintain and install every major brand, from standard efficiency through modern condensing units.
Common throughout the county's older villages and pre-war buildings. One-pipe and two-pipe systems, pressure controls, low water cutoffs, main venting and water hammer diagnosis.
Cast-iron radiators and baseboard loops across much of the older housing here. Circulators, zone valves, expansion tanks and controls.
Increasingly common on additions and retrofits where extending ductwork was impractical. Repair, maintenance and replacement across all brands.
Zoned heating and cooling without ductwork — the practical answer in older Westchester County homes with no duct chases. We are a Mitsubishi Diamond Contractor.
Still widespread in northern Westchester where natural gas does not reach every property. Burner service, combustion testing, nozzles, electrodes and primary controls.
Our fleet runs from Briarcliff Manor, roughly central to the county, and covers Westchester, Putnam and Rockland around the clock, 365 days a year including holidays.
The highest dealer designation Mitsubishi Electric awards, earned on installation quality and training — which matters wherever ductless is the practical answer.
We fabricate our own ductwork and transitions, which is what makes retrofits possible in older homes where nothing is a standard size.
Carey & Walsh has worked in this county since 1944. We know these houses, and we are still here when something needs attention in five years.
Our fully-stocked fleet covers all of Westchester County plus neighbouring Putnam and Rockland. Emergency calls are dispatched immediately, anywhere in the service area.
📋 Schedule Service in Westchester County
Have a question about your furnace, boiler, or AC that isn't answered here? Our team is happy to talk it through.
Call 914-762-9600Yes. No-heat and no-cooling calls are dispatched around the clock, 365 days a year including holidays. Westchester County is within our core service area and our fleet runs from Briarcliff Manor.
All of it, plus neighbouring Putnam and Rockland. Our base is in Briarcliff Manor, which sits roughly central to the county, so response times are consistent from the river towns through to the northern towns rather than dropping off at the edges of a territory.
Yes. Alongside residential work we service commercial properties across the county — rooftop units, split systems and light commercial heating and cooling, including multi-family buildings where one boiler serves many units.
Often yes. Where there are usable closets, chases or attic runs we fabricate ductwork in-house and can frequently make a conventional system work. Where that is genuinely impractical, ductless mini-splits give you zoned cooling without opening up the house.
Yes, and it is a genuine specialty rather than something we tolerate. Low water cutoffs, pressuretrols, main venting, near-boiler piping and water hammer are routine work for us. Banging radiators are usually a pressure, pitch or venting problem — not a failing boiler.
All major heating and cooling brands. Our vehicles carry the parts most commonly needed on the equipment found in this area, which is why a large share of repair calls are finished on the first visit.
Yes. Seasonal maintenance is the single most effective way to avoid an emergency call, particularly on steam and older equipment where small faults compound quietly.
It depends entirely on what has failed, and quoting a figure before seeing the system would not be honest. You get a written estimate with parts and labor separated before any work begins, and nothing starts until you approve it. Call 914-762-9600 for a free estimate.
