Start here if you read nothing else: this page covers Columbia County, Oregon — 659 square miles, 0 listed communities, a centroid northwest of the Portland metro's centre. Its climate record, from VANCOUVER PEARSON AP, WA US, sets a heating pressure on its systems. TempReach USA publishes the homework and routes the call; an independent local HVAC technician serving the county does the work.
Climate on this page is not a national average wearing a county's name. It is the specific record at VANCOUVER PEARSON AP, WA US: 54.0 degrees as the average temperature, 37.47 inches of precipitation, 14.6 hot days and 44.8 freezing nights in the average year, 4,400 heating degree days against 400 cooling degree days. Columbia County — 659 square miles, 8 ZIP codes, 0 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
The heating season also has an address pattern in Columbia County. Its 8 ZIP codes divide 659 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 — northwest of the Portland metro's centre, roughly 31 miles from the metro's centre — shapes which parts of the county feel the Portland 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.
Distance is the county fact the climate table leaves out. Columbia County's centroid lies northwest of the Portland metro's centre, roughly 31 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 8 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
The ZIP list is the county's working map. Columbia County carries 8 codes, running from 97016 through 97053 in the middle of the list to 97064 at its end, and every code on it is a small housing census of its own — the building decades, the system generations, the duct materials of its streets. Heating and cooling work routed by those codes meets the county in slices, and the slices differ more than the county's shared climate record would suggest.
Read the map around Columbia County and a working region appears: Washington County, Yamhill County, Clackamas County, Clark County are the neighbouring names at the head of its list of 6, 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.
Consider what one year asks of a system in Columbia County: a cooling season measured at 400 degree days, a heating season at 4,400, 14.6 days of serious heat and 44.8 freezing nights, and 37.47 inches of precipitation working on every outdoor unit through all of it. No single figure is remarkable; the combination is the county's climate, and it is the combination a system has to survive for fifteen or twenty years. The service patterns described on this page are that arithmetic, playing out across 659 square miles of housing.
The codes carry the community story in Columbia County: 8 of them, from 97016 through to 97064, at 82.3 square miles per code across the county's 659 square miles. Nobody here describes a call by its town, because the record gives the county no towns to describe it by; they describe it by its code and its road. The housing behind those codes was still built decade by decade, and the systems still age decade by decade — the county simply files the diary by ZIP instead of by place.
Age is the county's second climate. The Portland metro's median home was built in 1983, and 46.2% of its homes predate 1980 — in Columbia 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, 26.5% 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.
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 Columbia County's case, across 659 square miles that hold 0 listed communities and 8 ZIP codes, northwest of the Portland metro's centre. 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 Columbia County and the Portland metro.
