Polk County in one paragraph: 741 square miles in Oregon, 6 ZIP codes, a heating climate pressure read from the normals at SALEM MCNARY FLD, OR US, and housing that answers 4,340 heating degree days against 401 cooling degree days a year. TempReach USA is a referral service, not an HVAC company — one call connects you with an independent local HVAC technician serving this county.
One record, one county: the normals at SALEM MCNARY FLD, OR US — 4,340 heating degree days, 401 cooling degree days, 40.08 inches of precipitation, an average temperature of 54.1 degrees — applied to Polk County's own 741 square miles and its 6 ZIP codes. The figures are the Salem metro's; the ground they are applied to, lying west of the Salem metro's centre, is this county's alone, and this section reads the two together.
The neighbours tell part of Polk County's heating story: Marion County are among the counties around it, all reading the same record at SALEM MCNARY FLD, OR US, all filling their diaries in the same cold weeks. What separates this county's share is its own ground — 741 square miles lying west of the Salem metro's centre, roughly 20 miles from the metro's centre — and its own housing, fitted across the decades its communities were built. The season is regional; the failures are local, one system at a time, at addresses only this county has.
Set the county inside its metro and the picture completes. Polk County answers to the Salem metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 3 communities, 6 ZIP codes, one county's worth of systems ageing under the record kept at SALEM MCNARY FLD, OR US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
6 ZIP codes reach into Polk County's 741 square miles, among them 97304, 97338, 97344, 97351 — an average of 123.5 square miles of county ground per code. The codes are more than a mailing grid here: they are how the county's service ground divides in practice, each code holding its own mix of housing eras, its own streets of systems ageing on their own schedules. A call in one code and a call in the next can be the same fault in different decades of house.
Polk County sits alongside Marion County in the Salem area — 1 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 Polk County's own share of the picture separate.
The county's year divides by load. At one end, 18.3 days at 90 degrees or above pull the cooling season into its long peak; at the other, 49.4 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 SALEM MCNARY FLD, OR US is what those two ends average out to, and 40.08 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Polk 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.
Communities across Polk County include Dallas, Monmouth, Independence and its remaining communities — 3 listed places in all, spread over the county's 741 square miles in Oregon. Each community's housing was built in its own decades, so the heating and cooling diary reads differently from one name on that list to the next: older systems and original ductwork in the long-settled places, matched fleets ageing together in the subdivisions, and additions and conversions in the communities still growing at the county's edges.
Census figures give Polk County's heating and cooling its proportions. The metro it belongs to counts 165,046 housing units across 157,987 households, 62.7% of them owner-occupied, and the era mix runs 18.9% before 1960, 30.9% from 1960 to 1979, 26.4% from 1980 to 1999 and 23.8% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Polk County street, built forty years apart, can need entirely different conversations from the same technician.
A reader who only had Polk County's identifying figures would already know its shape: a county of 741 square miles in Oregon, 6 ZIP codes, 3 communities on the record, sitting west of the Salem metro's centre. 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.
