Chappaqua sits on wooded lots where properties are spread out, natural gas does not reach everywhere, and a good number of homes still run on oil. Carey & Walsh covers the whole town of New Castle — AC repair, boiler and furnace service, and 24/7 emergency response.
Chappaqua and the wider town of New Castle are more wooded and more spread out than most of Westchester, and that shapes the HVAC work. Natural gas service does not reach every road, so oil-fired heating remains common and properly tuned burners matter. Lots are large and houses sit well apart, which puts a premium on arriving with the right parts rather than scheduling a return visit. The housing itself ranges from older farmhouse and Colonial stock with hydronic heat to substantial newer construction running multi-zone forced air and heat pumps.
Riverfront villages like Chappaqua 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, Chappaqua 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.
Oil-fired boilers and furnaces are common here alongside gas and hydronic systems. Burner service, combustion testing and control diagnosis are routine work for us, as is modern high-efficiency equipment.
Larger homes here often need genuine zoning rather than a single system. We design multi-zone central air where ductwork allows, and ductless for additions, converted attics and spaces the original system never reached.
The most common heating system in Chappaqua's newer construction. We repair, maintain and install every major brand, from standard efficiency through modern condensing units.
Found in some of the older farmhouse and Colonial stock. One-pipe and two-pipe systems, pressure controls, low water cutoffs and main venting.
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 Chappaqua homes with no duct chases. We are a Mitsubishi Diamond Contractor.
Particularly common in Chappaqua and the wider New Castle area where natural gas does not reach every property. Burner service, combustion testing, nozzles and controls.
Chappaqua is covered around the clock, every day of the year. Our vehicles carry the parts most often needed on the equipment found here, which matters when properties are spread out.
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 Chappaqua 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.
Along with Chappaqua, our fleet regularly covers the surrounding communities and the rest of Westchester County.
📋 Schedule Service in Chappaqua
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. Chappaqua is within our core service area and our fleet runs from Briarcliff Manor, so response times here are short.
Yes, and it is a substantial part of our work here because natural gas does not reach every road in New Castle. Nozzles, electrodes, oil filters, burner motors, pumps, transformers, cad cells and primary controls, plus full combustion testing and burner tuning on Beckett, Riello and Carlin equipment.
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. We will tell you honestly which applies after looking at it.
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, whatever you may have been told.
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 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 faults compound quietly. Call to discuss what suits 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.
