In brief: 431 square miles of New York, a climate read from TETERBORO AP, NJ US's normals, and a heating pressure as the county's dominant one — 4,735 heating degree days set against 1,255 cooling degree days in an average year. TempReach USA does not do the work itself; it is a referral service, and one call connects you with an independent local HVAC technician serving Westchester County.
Before the narrative, the numbers themselves, because everything after them is commentary: at TETERBORO AP, NJ US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 28.9 days at 90 degrees or above, 89.0 nights at or below freezing, 46.29 inches of precipitation and degree-day totals of 4,735 heating against 1,255 cooling. Spread over 431 square miles, with the county's centroid northeast of the New York metro's centre and roughly 33 miles from the centre it is measured against, that record is Westchester County's working climate.
The neighbours tell part of Westchester County's heating story: New York County, Ocean County, Passaic County are among the counties around it, all reading the same record at TETERBORO AP, NJ US, all filling their diaries in the same cold weeks. What separates this county's share is its own ground — 431 square miles lying northeast of the New York metro's centre, roughly 33 miles from the metro's centre — and its own housing, fitted across the decades its communities were built. The season is regional; the failures are local, one system at a time, at addresses only this county has.
Distance is the county fact the climate table leaves out. Westchester County's centroid lies northeast of the New York metro's centre, roughly 33 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 74 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
Count the coverage from the codes upward: 10501, 10502 and 10503 are the first codes on Westchester County's list of 74, spread across its 431 square miles in New York. No two of those codes hold quite the same housing — one may be a settled community's streets, the next newer subdivisions, the next open county ground — so the same climate record produces a different run of calls inside each. The full list is printed on this page; the diary is written code by code.
Read the map around Westchester County and a working region appears: New York County, Ocean County, Passaic County, Putnam County are the neighbouring names at the head of its list of 21, and together these counties form the ground a local technician actually covers. The county line decides which page describes a home; it does not decide the weather the home's system faces, the decade its street was built in, or the season its diary fills. Those are regional — and the region, on this site, is a set of county pages that link to one another, as the cards below do.
There is a geography to Westchester County's seasons that the totals flatten. The county lies northeast of the New York metro's centre, roughly 33 miles from the centre the record is measured against, and its 431 square miles do not meet a hot week or a cold snap in one voice: the ground nearer the metro and the ground at the county's far edge live the same 28.9 hot days and 89.0 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Westchester County is a county of distinct communities rather than one continuous town: Yonkers, New Rochelle, Mount Vernon and its remaining communities are among the 3 places on its record, each with its own building era and its own stock of systems. Position plays its part as well — the county sits northeast of the New York metro's centre, so its communities meet the New York metro's weather at slightly different distances from the centre — but it is the place list that a service diary follows, name by name, through the year.
Age is the county's second climate. The New York metro's median home was built in 1959, and 73.8% of its homes predate 1980 — in Westchester County, that share is the older districts and the long-settled communities, where ductwork from an earlier equipment era still serves replacement systems. The newer share, 12.4% built since 2000, concentrates in the county's growth edges. The service diary divides along that line: deep equipment-and-duct conversations at the old end, first-replacement and control conversations at the new one.
There is a reason the coverage on this page is described county-first. Heating and cooling demand is generated house by house, and houses sit in counties: in Westchester County's case, across 431 square miles that hold 3 listed communities and 74 ZIP codes, northeast of the New York metro's centre. The metro frame matters — the station, the housing eras, the problem ranking all come from it — but the county is where the frame touches the ground, and the ground is where the systems are.
City pages carry the metro-wide homework — housing eras, the problem ranking, services in depth. This county sits inside their coverage.

TempReach USA is not an HVAC company. We employ no heating or cooling technicians, we run no service trucks, and we do not carry out HVAC work of any kind. This website and its call center exist for one purpose: to connect homeowners with independent local heating and cooling professionals who serve their area. When you call the number on this site, your call is routed to such a professional. From that point, everything about the job belongs to that professional and to you: the assessment, the work itself, the scheduling, what you are charged, and the terms of any agreement you reach. The professional who takes your job is solely responsible for it. The technician who arrives at your home runs their own business; they are not an employee, agent or subcontractor of TempReach USA. Our part is the information on these pages — assembled from Census Bureau housing data and NOAA climate records for each metro — and the routing of your call. We state this plainly on purpose: you should know exactly who you are hiring before anyone picks up a wrench or a gauge.
One call connects you with an independent local heating and cooling professional serving Westchester County and the New York metro.
