The short version of this page: Ada County runs to 1,052 square miles, its weather is the record kept at BOISE AIR TERMINAL, ID US — 5,320 heating degree days, 1,045 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 BOISE AIR TERMINAL, ID US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 11.51 inches a year; the temperature record averages 53.2 degrees, built from 54.9 days at 90 or above and 108.2 nights at or below freezing; the workload totals 5,320 heating degree days and 1,045 cooling degree days. Ada County is read through that record throughout this page.
Heating pressure in Ada County can be counted in codes as well as in degree days. From 83616 through 83705 to 83725, the county's 16 ZIP codes divide 1,052 square miles of housing that one cold record — 5,320 heating degree days, 108.2 freezing nights, kept at BOISE AIR TERMINAL, ID US — examines in a single night. The fault is usually an old one, an igniter or an exchanger at the end of its winters; the ground it is found on, code by code, is what makes the diary this county's.
The county's neighbours frame it as well: Boise County, Canyon County, Gem County are among the 4 counties on its neighbour list, and together they form the working ground around Ada County's own 1,052 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.
Count the coverage from the codes upward: 83616, 83634 and 83642 are the first codes on Ada County's list of 16, spread across its 1,052 square miles in Idaho. No two of those codes hold quite the same housing — one may be a settled community's streets, the next newer subdivisions, the next open county ground — so the same climate record produces a different run of calls inside each. The full list is printed on this page; the diary is written code by code.
Ada County sits alongside Boise County, Canyon County, Gem County in the Boise area — 4 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 Ada County's own share of the picture separate.
The county's year divides by load. At one end, 54.9 days at 90 degrees or above pull the cooling season into its long peak; at the other, 108.2 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 53.2 degrees at BOISE AIR TERMINAL, ID US is what those two ends average out to, and 11.51 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Ada 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.
Ada County is a county of distinct communities rather than one continuous town: Boise City, Meridian, Eagle and Kuna are among the 7 places on its record, each with its own building era and its own stock of systems. Position plays its part as well — the county sits close to the centre of the Boise metro, so its communities meet the Boise metro's weather at slightly different distances from the centre — but it is the place list that a service diary follows, name by name, through the year.
The housing behind Ada County's systems is the Boise metro's housing, read at county scale. The largest single share of the metro's homes was built since 2000 — 43.1% of the stock — with 30.3% of homes predating 1980 and 43.1% arriving since 2000, around a median build year of 1996. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to since 2000 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.
One way to hold Ada County in mind is as the local layer of a wider dataset. Above it sits the Boise metro, with its Census housing profile and its NOAA station at BOISE AIR TERMINAL, ID US. At this level sit the county's own numbers — 1,052 square miles, 4 neighbouring counties, 16 ZIP codes, 7 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.
One call connects you with an independent local heating and cooling professional serving Ada County and the Boise metro.
