The short version of this page: Yamhill County runs to 716 square miles, its weather is the record kept at VANCOUVER PEARSON AP, WA US — 4,400 heating degree days, 400 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.
The station for this county's metro is VANCOUVER PEARSON AP, WA US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 37.47 inches a year; the temperature record averages 54.0 degrees, built from 14.6 days at 90 or above and 44.8 nights at or below freezing; the workload totals 4,400 heating degree days and 400 cooling degree days. Yamhill County is read through that record throughout this page.
Count the cold from the ground up in Yamhill County and the figures arrange themselves: 4,400 heating degree days against 400 cooling degree days, 44.8 freezing nights in an average year, and a housing stock spread over 716 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.
The county's neighbours frame it as well: Multnomah County, Skamania County, Washington County are among the 6 counties on its neighbour list, and together they form the working ground around Yamhill County's own 716 square miles. A system near a shared border lives in both counties' weather at once, whichever page describes its home — the pages divide the map so the record can be read county by county, and the links between them keep the whole in view.
The ZIP list is the county's working map. Yamhill County carries 11 codes, running from 97101 through 97128 in the middle of the list to 97396 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.
Position first: Yamhill County lies southwest of the Portland metro's centre, roughly 41 miles from the metro's centre as the map measures it, with Multnomah County, Skamania County, Washington 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.
There is a geography to Yamhill County's seasons that the totals flatten. The county lies southwest of the Portland metro's centre, roughly 41 miles from the centre the record is measured against, and its 716 square miles do not meet a hot week or a cold snap in one voice: the ground nearer the metro and the ground at the county's far edge live the same 14.6 hot days and 44.8 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Read Yamhill County through its record and two facts stand together: its named communities are McMinnville, and its land runs to 716 square miles. Between those facts sits the county's real housing — homes in the named places, homes along the roads the record does not name, all of them heating and cooling under the climate recorded at VANCOUVER PEARSON AP, WA US. This page keeps both facts in view, because a county page that only described its named places would miss most of the county it is about.
The growth figures deserve their own reading in Yamhill County. 26.5% of the Portland 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 46.2% 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.
One way to hold Yamhill County in mind is as the local layer of a wider dataset. Above it sits the Portland metro, with its Census housing profile and its NOAA station at VANCOUVER PEARSON AP, WA US. At this level sit the county's own numbers — 716 square miles, 6 neighbouring counties, 11 ZIP codes, 1 listed places — and below it, not published anywhere, sit the individual homes whose systems all of it describes. This page works at the middle level, where the data is still local enough to act on.
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.
