Clay County in one paragraph: 342 square miles in West Virginia, 12 ZIP codes, a heating climate pressure read from the normals at CHARLESTON YEAGER AP, WV US, and housing that answers 4,353 heating degree days against 1,162 cooling degree days a year. TempReach USA is a referral service, not an HVAC company — one call connects you with an independent local HVAC technician serving this county.
Climate on this page is not a national average wearing a county's name. It is the specific record at CHARLESTON YEAGER AP, WV US: 56.1 degrees as the average temperature, 46.24 inches of precipitation, 23.6 hot days and 94.3 freezing nights in the average year, 4,353 heating degree days against 1,162 cooling degree days. Clay County — 342 square miles, 12 ZIP codes, 0 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
Heating writes this county's HVAC calendar. With 4,353 heating degree days against 1,162 cooling degree days in the normals recorded at CHARLESTON YEAGER AP, WV US, the systems across Clay County earn their keep in the cold half of the year: furnaces and heat pumps cycling through 94.3 nights at or below freezing, when a breakdown stops being a comfort problem and becomes a household one. The pressure shows up as midwinter failures on the oldest equipment first, and a maintenance calendar that has to be kept in autumn — because by the time the cold arrives, the county's systems are already on stage.
The county's ground shapes the work in one more way: 342 square miles is a lot of roofs for a service map to hold, and Clay County's homes divide between its listed communities — — 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.
There is a scale fact hidden in Clay County's ZIP codes: 12 codes across 342 square miles works out to 28.5 square miles per code, which makes a service call here a matter of ground as well as of systems. The codes on the metro-facing side of the county — the county sits northeast of the Charleston metro's centre — and the codes at its far edge hold different ground, but both ends ask the same climate questions of their heating and cooling, at different distances.
Position first: Clay County lies northeast of the Charleston metro's centre, roughly 23 miles from the metro's centre as the map measures it, with Boone County, Kanawha County among the counties around it. Neighbourhood at county scale matters to heating and cooling because systems do not respect the border — the same subdivisions' building decades continue across it, the same cold snaps and heat waves examine both sides in the same night — while each county's page, this one included, keeps the local figures distinct.
Two numbers organise Clay County's heating and cooling year: 4,353 and 1,162, the heating and cooling degree days in the normals at CHARLESTON YEAGER AP, WV US. Whichever runs larger decides the county's dominant pressure — here, a heating one — and with it the season a household should prepare for first. The supporting figures fill in the texture: 56.1 degrees as the year's average temperature, 23.6 hot days, 94.3 freezing nights, 46.24 inches of precipitation. Every paragraph on this page is, in the end, a reading of those six numbers on this county's ground.
Clay County is recorded by land and code rather than by named places: 342 square miles in West Virginia, lying northeast of the Charleston metro's centre, roughly 23 miles from the metro's centre as the map measures it. Its households sit inside the Charleston metro's coverage and share its climate record, but their heating and cooling diary is written at address level — a system in a house on a county road, ageing on its own house's schedule. A county page built from a place list would have little to say here; a page built from the ground itself has the county as it is.
The growth figures deserve their own reading in Clay County. 11.7% of the Charleston metro's homes were built since 2000 — the largest or near-largest band in many of its counties — and those homes are now old enough that their first systems are reaching replacement age together, subdivision by subdivision. Set against them, the 68.1% of the metro's stock that predates 1980 is deep into its second and third systems. One county, two replacement waves running at once, and a maintenance diary that has to serve both.
Put the county's coverage facts in one place and they read like this: 342 square miles of land in West Virginia, 0 listed communities, 12 ZIP codes, 2 neighbouring counties on the record, and a place inside the Charleston metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
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 Clay County and the Charleston metro.
