The short version of this page: Frederick County runs to 413 square miles, its weather is the record kept at MARTINSBURG E WV RGNL AP, WV US — 4,947 heating degree days, 1,013 cooling degree days — and its systems live under a heating pressure. One call to TempReach USA, a referral service rather than an HVAC company, connects you with an independent local HVAC technician serving the county.
Read Frederick County's weather the way this page reads it: through the thirty-year normals kept at MARTINSBURG E WV RGNL AP, WV US for the Winchester metro. Those normals give the county 1,013 cooling degree days and 4,947 heating degree days a year, 38.97 inches of precipitation, 26.2 days at 90 degrees or above, 104.3 nights at or below freezing, and an average temperature of 54.1 degrees — the fixed background every system in the county works against.
Count the cold from the ground up in Frederick County and the figures arrange themselves: 4,947 heating degree days against 1,013 cooling degree days, 104.3 freezing nights in an average year, and a housing stock spread over 413 square miles whose heating plant was fitted in the decades its communities were built. The diary that follows is written street by street — ignition and exchanger work where the stock is oldest, control and sensor work where it is newest — and the county's technicians read the address before they read the fault.
One more county fact belongs in the record: position. Frederick County sits at 39.20366, -78.263829 on the map — the centroid of a county whose communities spread across 413 square miles of Virginia. Position decides which end of the metro's weather arrives first and which of its service patterns a household here meets most; the rest of this page is that position, read through the climate record and the metro's data.
Routing in Frederick County is written in five digits. The county's codes begin at 22602 and run to 22656, 9 in total, and between the first and the last sits the county's full spread of ground — 413 square miles from the metro-facing edge to the far side. A technician's week here is a tour of those codes, and the tour is also a tour of the county's building history, because each code's systems were largely fitted when that code's streets were built.
Frederick County sits alongside Hampshire County, Winchester City in the Winchester area — 2 neighbouring counties share its coverage map in all, and the borders between them are lines on a map rather than changes in the weather. The same station record travels across those borders, the same housing decades appear on both sides, and a technician's ground here is really the cluster: this county and its neighbours, read together, with this page keeping Frederick County's own share of the picture separate.
The county's year divides by load. At one end, 26.2 days at 90 degrees or above pull the cooling season into its long peak; at the other, 104.3 nights at or below freezing do the same for heating; between them sit the shoulder weeks when neither plant runs hard. An average temperature of 54.1 degrees at MARTINSBURG E WV RGNL AP, WV US is what those two ends average out to, and 38.97 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Frederick County's households plan around that division — service ahead of the taller peak, filters and checks in the shoulders — whether they name it or not.
The county's place list tells its own story. Shawneeland (2,653 residents) is the largest of the 6 communities the record names for Frederick County, with Stephens City (2,338 residents) behind it and Lake Holiday and Middletown further down the list. A technician working this county works all of those places in a single week, and the systems change character with the address: the era a community was built in decides whether the call is about an ageing furnace, a condenser at the end of its summers, or ductwork that predates the equipment it now serves.
Spread the metro's eras over Frederick County's own ground and the housing paragraph becomes a map: 413 square miles, 9 ZIP codes at 45.9 square miles per code, and a stock whose largest band was built between 1980 and 1999 (33.6%), whose pre-1980 share runs to 35.4% and whose post-2000 share runs to 31.0%. 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 Frederick County's case, across 413 square miles that hold 6 listed communities and 9 ZIP codes, close to the centre of the Winchester 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 Frederick County and the Winchester metro.
