HVAC Company in White Plains, NY
Dalton Heating & Air handles heating and cooling work across White Plains, NY, from split-levels off Mamaroneck Avenue to prewar colonials near the downtown core. Most jobs here come down to two things: a housing stock that skews older, and summers that punish systems that haven’t been maintained. Our crews carry parts for nine major brands, show up inside the stated window, and put every price in writing before work starts. If you need an HVAC company in White Plains that answers the phone with a live person, call (361) 306-9515.
Why White Plains Homes Are Different
White Plains sits at roughly 200 feet of elevation with the Bronx River running along its western edge, which means humidity collects in the low-lying streets near Battle Hill and rises into the apartment blocks around downtown. That moisture loads down air conditioners faster than homeowners expect, and coil corrosion is a real pattern we see on systems five years and older. Winters land hard here too, with January nights regularly dipping into the teens, so furnaces in the older housing stock along Fisher Avenue and Gedney Way take more cycles than equipment in milder parts of the county.
Much of the single-family housing dates from the 1920s through the 1960s. That means ductwork that was built for gravity furnaces, retrofitted for forced air, and often undersized for today’s equipment. In condos and co-ops near the White Plains Transit Center and along Main Street, we deal with through-wall units and packaged heat pumps instead, which changes both parts availability and how repair work gets scheduled. A furnace in a prewar colonial on Ridgeway behaves nothing like a heat pump in a high-rise on Martine Avenue, and the pricing reflects that.
Permits are handled through the City of White Plains Building Department. For equipment replacement work, the permit is part of the job, not an afterthought, and the inspection schedule can add a day or two to a full system install. Homeowners in the gated communities off Westchester Avenue and the co-op buildings south of the Cross Westchester Expressway should also plan around board approval windows if the work touches shared HVAC infrastructure.
Our Main White Plains Services
These are the three jobs White Plains homeowners call us about most, each with its own page that covers pricing, process, and what to expect from the first call to the final walkthrough.
AC Repair in White Plains
A White Plains air conditioner fails in two common ways: it runs but won’t cool, or it won’t run at all. The first is usually a refrigerant leak, a failed capacitor, or a clogged coil from the humidity we described above. The second is often electrical, and it tends to happen on the hottest afternoon of the year. Our technicians show up with common capacitors, contactors, and fan motors on the truck, so most calls are same-day fixes, and every repair gets a written one-year guarantee. If it fails inside that year, we return at no charge. That’s The Garrison Standard, and it applies to every job, no exceptions. Read the full breakdown at AC Repair in White Plains.

Heat Pump Installation in White Plains
Heat pumps make particular sense in White Plains because they pull double duty: cooling during the humid summers and heating through the shoulder months, which lowers gas use in homes that still have forced-air ducts. In the condo buildings around downtown, a ductless heat pump is sometimes the only viable retrofit when a through-wall AC dies. Sizing matters more here than most homeowners realize, and we calculate load per room, not per square foot, before quoting anything. Install pricing is fixed in writing and includes the permit. Read Heat Pump Installation in White Plains for full cost ranges and what to expect.

Furnace Repair in White Plains
When a furnace dies in a White Plains January, it’s not an inconvenience, it’s a pipe-freeze risk. We respond to no-heat calls as emergencies, and our trucks carry igniters, flame sensors, gas valves, and pressure switches for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard units. Older furnaces in the colonials off Gedney Way and North Street tend to fail on heat exchangers and inducer motors, and we’ll show you the failed part before we quote the replacement. Every repair carries the full written one-year guarantee. Details are on Furnace Repair in White Plains.

Brands We Service in White Plains
Our techs are factory-trained on Goodman, Rheem, York, and Daikin, and we keep their most common repair parts stocked on local trucks.

Pricing for HVAC Company in White Plains, NY
| Service | Typical range in White Plains |
|---|---|
| AC repair (parts and labor) | $150 – $650 |
| Furnace repair (parts and labor) | $150 – $700 |
| AC installation (full system) | $3,500 – $7,500 |
| Seasonal tune-up | $80 – $200 |
What pushes a White Plains job toward the high end of those ranges is usually equipment age. A 25-year-old unit in a prewar home needs more than a standard part swap, and working around finished basements in the neighborhoods off Mamaroneck Avenue adds labor time. Regardless of the number, the price is in writing before any work starts, and that number doesn’t move when the work gets harder than expected.
Neighborhoods We Serve in White Plains
We work across every part of White Plains, from the single-family streets off North Street to the high-rise and co-op buildings near the Metro-North station. Our typical response time for emergency calls anywhere in the city is under two hours during business days.
