Hampshire County covers 527 square miles in Massachusetts. Its climate is read from the normals recorded at WESTFIELD BARNES MUNI AP, MA US — 6,330 heating degree days against 677 cooling degree days — and its dominant pressure is a heating one. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving the county.
Climate on this page is not a national average wearing a county's name. It is the specific record at WESTFIELD BARNES MUNI AP, MA US: 49.4 degrees as the average temperature, 45.16 inches of precipitation, 17.7 hot days and 143.6 freezing nights in the average year, 6,330 heating degree days against 677 cooling degree days. Hampshire County — 527 square miles, 26 ZIP codes, 7 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
Divide Hampshire County's cold by its coverage and the heating diary sharpens: 26 ZIP codes over 527 square miles, 20.3 square miles per code on average, the codes running from 01002 to 01243. A furnace failure in the code nearest the metro reads differently from one at the county's far edge — not in the fault, which is the same worn igniter or tired blower, but in everything around it: the drive, the house's decade, the odds the system has already been replaced once. The cold itself, 6,330 heating degree days of it, is shared; the ground it is answered on is not.
The county's ground shapes the work in one more way: 527 square miles is a lot of roofs for a service map to hold, and Hampshire County's homes divide between its listed communities — Amherst Town, Northampton, Ware, Belchertown, Hatfield, Granby — and the roads between them. A technician routed here is working a county, not a street: the drive between calls is part of the diary, and the systems at each end of it were fitted in the decades those communities were built.
A ZIP code in Hampshire County is a small climate-and-housing district of its own. The county's 26 codes — 01002, 01003, 01007, 01012 among them — all read the same normals from WESTFIELD BARNES MUNI AP, MA US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.
A county with no neighbours on its record is a simpler map: Hampshire County, 527 square miles of Massachusetts, sitting close to the centre of the Amherst metro and carrying the Amherst metro's coverage at its edge. Nothing about the work simplifies with the map — the county's housing still spans its building decades, its systems still answer the full degree-day record — but the page can keep its whole attention on one county's ground, which is what it does.
The precipitation figure earns its place in Hampshire County's record: 45.16 inches a year at WESTFIELD BARNES MUNI AP, MA US, falling through both the cooling months and the heating ones. Rain loads condensate systems in summer, tests outdoor units and venting in winter, and keeps the ground around the county's 26 ZIP codes cycling between wet and dry in a way that shows up in crawl spaces and condensate lines. Set beside 17.7 hot days and 143.6 freezing nights, it completes the picture of what the county's equipment actually lives in.
Name the ground and the work follows: in Hampshire County, the 7 listed communities — Amherst Town, Northampton, Ware, Belchertown among them — hold the county's homes, and the homes hold its heating and cooling systems. The largest places supply the steadiest run of calls; the smaller communities supply the long drives and the systems fitted when those places were built. Either way, the county's 527 square miles are not read as one housing stock on this page, because on the ground they are not one: they are these communities, in this order, with these names.
Spread the metro's eras over Hampshire County's own ground and the housing paragraph becomes a map: 527 square miles, 26 ZIP codes at 20.3 square miles per code, and a stock whose largest band was built before 1960 (40.7%), whose pre-1980 share runs to 64.7% and whose post-2000 share runs to 13.1%. The percentages are the metro's; the streets they land on are this county's, and a technician driving from one end of the county to the other drives through the bands in sequence.
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 Hampshire County's case, across 527 square miles that hold 7 listed communities and 26 ZIP codes, close to the centre of the Amherst metro. 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 Hampshire County and the Amherst metro.
