From a steam boiler in a pre-war building off Mamaroneck Avenue to a ductless system in a downtown condo where ductwork was never an option, Carey & Walsh has kept White Plains comfortable for over 80 years. Furnace and boiler repair, AC installation, and 24/7 emergency response across the county seat.
White Plains is the most varied HVAC environment in Westchester. Downtown is dense — high-rise condos, co-ops and apartment buildings where a conventional split system was never practical, and where ductless and through-wall equipment does most of the work. Push out into Gedney, Battle Hill, Highlands or North Broadway and it changes completely: single-family homes across seventy years of construction, many still on steam or hot-water heat with original cast-iron radiators. Then there is the commercial corridor along Westchester Avenue and the office parks around it. We work across all three, and the equipment that suits one is frequently wrong for the others.
Riverfront villages like White Plains 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, White Plains 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.
White Plains runs on everything from original steam systems in pre-war buildings to modern condensing furnaces in the outer neighbourhoods. We repair, maintain and replace all of it — including the oil-fired and steam equipment many contractors in the area have stopped servicing altogether.
Cooling a White Plains home depends entirely on the building. Where ductwork exists, central air is straightforward. In a downtown co-op or a century-old house with no duct chases, ductless is usually the only sensible answer — and as a Mitsubishi Diamond Contractor, that is work we do constantly here.
The standard in White Plains homes built from the post-war period onward, particularly through Gedney and the Highlands. We service every major brand, from standard efficiency through modern condensing units.
Common in the pre-war buildings and older houses closer to downtown. One-pipe and two-pipe systems, pressure controls, low water cutoffs, main venting and the water hammer that comes with all of it.
Cast-iron radiators and baseboard loops across much of the older single-family stock. Circulators, zone valves, expansion tanks and controls.
Increasingly common on retrofits and additions where extending ductwork was impractical. Repair, maintenance and replacement across all brands.
The workhorse of downtown White Plains — condos, co-ops and apartments where central ductwork does not exist and cannot reasonably be added. We are a Mitsubishi Diamond Contractor.
Still in service across parts of the city and the surrounding towns. Burner service, combustion testing, nozzles and controls.
A no-heat call in January or a failed condenser in August cannot wait. Our technicians are on call around the clock, every day of the year, and White Plains is minutes from our Briarcliff Manor base.
The highest dealer designation Mitsubishi Electric awards — which matters here, because ductless is the default answer in so much of the downtown housing stock.
We fabricate our own ductwork and transitions, which is what makes retrofits possible in older White Plains homes where nothing is a standard size.
Carey & Walsh has been working in this county since 1944. We know these buildings, and we are still here when something needs attention in five years.
Along with White Plains, our fleet regularly covers the surrounding central Westchester communities and the rest of the county.
📋 Schedule Service in White Plains
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, and it is a large part of what we do in the city. Downtown buildings rarely have room for conventional ducted systems, so most of the work is ductless mini-splits, through-wall units and replacements of existing equipment. We are a Mitsubishi Diamond Contractor, which is the relevant credential for that kind of installation.
Often yes, though it depends on the house. Where there are usable chases, closets or attic runs, we fabricate our own ductwork in-house and can frequently make a conventional system work. Where that is genuinely impractical, ductless gives you zoned cooling without tearing the house apart. We will tell you honestly which situation you are in after looking at it.
Yes. Steam is common in the pre-war buildings and older houses closer to downtown, and it is a specialty many contractors have quietly abandoned. 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.
White Plains is close to our Briarcliff Manor base and we run a full fleet, so response times here are among our fastest. No-heat and no-cooling calls are dispatched around the clock, 365 days a year including holidays.
Yes. Alongside residential work we service commercial properties throughout the Westchester Avenue corridor and the surrounding office parks — rooftop units, split systems and light commercial heating and cooling.
All major brands. Our technicians carry common parts for the equipment most often found in this area, which is why a large share of repair calls are completed on the first visit rather than after a parts order.
Yes. Seasonal maintenance is the single most effective way to avoid an emergency call, particularly on steam and older equipment where small problems compound quietly. Call to discuss what makes sense for your system.
It depends entirely on what has failed, and quoting a figure before seeing the system would not be honest. What we can promise is a written estimate with parts and labor separated before any work begins, and nothing starting until you approve it. Call 914-762-9600 for a free estimate.
