Franklin County covers 772 square miles in Pennsylvania. Its climate is read from the normals recorded at HAGERSTOWN WASHINGTON CO AP, MD US — 4,716 heating degree days against 1,248 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.
The station for this county's metro is HAGERSTOWN WASHINGTON CO AP, MD US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 35.6 inches a year; the temperature record averages 55.4 degrees, built from 23.8 days at 90 or above and 93.2 nights at or below freezing; the workload totals 4,716 heating degree days and 1,248 cooling degree days. Franklin County is read through that record throughout this page.
There is a housing arithmetic under Franklin County's heating season. The metro it belongs to built its largest share of homes before 1960 — 30.2% of the stock — with the next share between 1980 and 1999 at 24.8%, around a median build year of 1978. Fitted into those eras, the county's furnaces and heat pumps meet 93.2 freezing nights at very different ages, and the heating diary divides accordingly: deep repair conversations in the older bands, first-replacement conversations in the newer ones.
The county's ground shapes the work in one more way: 772 square miles is a lot of roofs for a service map to hold, and Franklin County's homes divide between its listed communities — Chambersburg, Waynesboro, Greencastle, Guilford, Wayne Heights, State Line — 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.
Count the coverage from the codes upward: 17201, 17202 and 17210 are the first codes on Franklin County's list of 28, spread across its 772 square miles in Pennsylvania. 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.
A county with no neighbours on its record is a simpler map: Franklin County, 772 square miles of Pennsylvania, sitting close to the centre of the Chambersburg metro and carrying the Chambersburg 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.
A year in Franklin County, counted the way a technician counts it, is not twelve months but two workloads and the weeks between them. The first workload is written as 1,248 cooling degree days, the second as 4,716 heating degree days; 35.6 inches of precipitation fall across both, and the average temperature of 55.4 degrees is simply the figure the two workloads leave behind when they are averaged. The county's heating pressure is whichever workload the count puts first — and the maintenance year is arranged around that ordering.
The county's place list tells its own story. Chambersburg (22,051 residents) is the largest of the 14 communities the record names for Franklin County, with Waynesboro (11,044 residents) behind it and Greencastle and Guilford 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.
Age is the county's second climate. The Chambersburg metro's median home was built in 1978, and 53.1% of its homes predate 1980 — in Franklin 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, 22.1% 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.
A reader who only had Franklin County's identifying figures would already know its shape: a county of 772 square miles in Pennsylvania, 28 ZIP codes, 14 communities on the record, sitting close to the centre of the Chambersburg metro. What the figures cannot say alone is how the ground feels to work — the drives between calls, the mix of decades in the housing, the season that runs taller — and that is what the rest of this page is for, section by section.
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 Franklin County and the Chambersburg metro.
