Warren County covers 215 square miles in Virginia. Its climate is read from the normals recorded at WASHINGTON DC DULLES AP, VA US — 4,604 heating degree days against 1,233 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 WASHINGTON DC DULLES AP, VA US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 43.24 inches a year; the temperature record averages 55.7 degrees, built from 32.7 days at 90 or above and 101.7 nights at or below freezing; the workload totals 4,604 heating degree days and 1,233 cooling degree days. Warren County is read through that record throughout this page.
The heating season also has an address pattern in Warren County. Its 3 ZIP codes divide 215 square miles into service ground where the same January night lands on older streets, subdivisions and edge communities at once, and the county's position — west of the Washington metro's centre, roughly 40 miles from the metro's centre — shapes which parts of the county feel the Washington metro's cold at full strength. The systems answer accordingly: one long heating season, read ZIP by ZIP, with the oldest furnaces and heat exchangers carrying the heaviest share of it.
Set the county inside its metro and the picture completes. Warren County answers to the Washington metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 0 communities, 3 ZIP codes, one county's worth of systems ageing under the record kept at WASHINGTON DC DULLES AP, VA US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
Routing in Warren County is written in five digits. The county's codes begin at 22610 and run to 22642, 3 in total, and between the first and the last sits the county's full spread of ground — 215 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.
Read the map around Warren County and a working region appears: Montgomery County, Prince George's County, Prince William County, Rappahannock County are the neighbouring names at the head of its list of 22, 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.
The county's year divides by load. At one end, 32.7 days at 90 degrees or above pull the cooling season into its long peak; at the other, 101.7 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 55.7 degrees at WASHINGTON DC DULLES AP, VA US is what those two ends average out to, and 43.24 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Warren 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.
Warren County is recorded by land and code rather than by named places: 215 square miles in Virginia, lying west of the Washington metro's centre, roughly 40 miles from the metro's centre as the map measures it. Its households sit inside the Washington 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 county's position frames its housing as well. Warren County lies west of the Washington metro's centre, roughly 40 miles out, and the metro's era mix — 28.1% built between 1980 and 1999, 25.9% since 2000, median year 1983 — reads at this distance with a county accent: the shares nearer the centre and the shares at the edge were platted in different decades of the metro's growth. Which band a given Warren County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
Coverage, for Warren County, is a set of overlapping maps. The land map is 215 square miles. The address map is 3 ZIP codes and 0 listed communities. The service map is the Washington metro, whose coverage the county sits inside — west of the Washington metro's centre, roughly 40 miles from its centre. The weather map is one station's record, kept at WASHINGTON DC DULLES AP, VA US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.
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 Warren County and the Washington metro.
