The short version of this page: Washoe County runs to 6,316 square miles, its weather is the record kept at RENO TAHOE INTL AP, NV US — 4,669 heating degree days, 1,038 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.
Before the narrative, the numbers themselves, because everything after them is commentary: at RENO TAHOE INTL AP, NV US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 65.1 days at 90 degrees or above, 121.9 nights at or below freezing, 7.35 inches of precipitation and degree-day totals of 4,669 heating against 1,038 cooling. Spread over 6,316 square miles, with the county's centroid northwest of the Reno metro's centre and roughly 70 miles from the centre it is measured against, that record is Washoe County's working climate.
The heating season also has an address pattern in Washoe County. Its 26 ZIP codes divide 6,316 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 Reno metro's centre, roughly 70 miles from the metro's centre — shapes which parts of the county feel the Reno 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.
The county's neighbours frame it as well: Lyon County, Storey County are among the 2 counties on its neighbour list, and together they form the working ground around Washoe County's own 6,316 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. Washoe County carries 26 codes, running from 89402 through 89502 in the middle of the list to 89704 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 Washoe County and a working region appears: Lyon County, Storey County are the neighbouring names at the head of its list of 2, 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.
There is a geography to Washoe County's seasons that the totals flatten. The county lies northwest of the Reno metro's centre, roughly 70 miles from the centre the record is measured against, and its 6,316 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 65.1 hot days and 121.9 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Name the ground and the work follows: in Washoe County, the 9 listed communities — Reno, Sparks, Fernley, Sun Valley among them — hold the county's homes, and the homes hold its heating and cooling systems. The largest places supply the steadiest run of calls; the smaller communities supply the long drives and the systems fitted when those places were built. Either way, the county's 6,316 square miles are not read as one housing stock on this page, because on the ground they are not one: they are these communities, in this order, with these names.
Look at the second era as well as the first and Washoe County's stock comes into focus. After the dominant band — homes built since 2000, 34.2% of the metro's total — the next share was built between 1980 and 1999, at 31.1%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.
Put the county's coverage facts in one place and they read like this: 6,316 square miles of land in Nevada, 9 listed communities, 26 ZIP codes, 2 neighbouring counties on the record, and a place inside the Reno metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
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 Washoe County and the Reno metro.
