Start here if you read nothing else: this page covers Canyon County, Idaho — 587 square miles, 5 listed communities, a centroid west of the Boise metro's centre. Its climate record, from BOISE AIR TERMINAL, ID 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 BOISE AIR TERMINAL, ID US: 53.2 degrees as the average temperature, 11.51 inches of precipitation, 54.9 hot days and 108.2 freezing nights in the average year, 5,320 heating degree days against 1,045 cooling degree days. Canyon County — 587 square miles, 10 ZIP codes, 5 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 Canyon County. Its 10 ZIP codes divide 587 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 — west of the Boise metro's centre, roughly 24 miles from the metro's centre — shapes which parts of the county feel the Boise 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.
One more county fact belongs in the record: position. Canyon County sits at 43.625795, -116.709058 on the map — the centroid of a county whose communities spread across 587 square miles of Idaho. Position decides which end of the metro's weather arrives first and which of its service patterns a household here meets most; the rest of this page is that position, read through the climate record and the metro's data.
There is a scale fact hidden in Canyon County's ZIP codes: 10 codes across 587 square miles works out to 58.7 square miles per code, which makes a service call here a matter of ground as well as of systems. The codes on the metro-facing side of the county — the county sits west of the Boise metro's centre — and the codes at its far edge hold different ground, but both ends ask the same climate questions of their heating and cooling, at different distances.
The counties around Canyon County include Ada County, Boise County, Gem County, and the whole group shares the Boise metro's climate record from BOISE AIR TERMINAL, ID US. What the neighbours do not share is this county's ground: 587 square miles, 10 ZIP codes, a centroid west of the Boise metro's centre. Service patterns cross the county line freely — a cold week fills diaries on both sides of it — but the mix of housing and systems on each side is its own, which is why each county in the group carries its own page.
There is a geography to Canyon County's seasons that the totals flatten. The county lies west of the Boise metro's centre, roughly 24 miles from the centre the record is measured against, and its 587 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 54.9 hot days and 108.2 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Communities across Canyon County include Nampa, Caldwell, Middleton and Nyssa — 5 listed places in all, spread over the county's 587 square miles in Idaho. 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.
The county's position frames its housing as well. Canyon County lies west of the Boise metro's centre, roughly 24 miles out, and the metro's era mix — 43.1% built since 2000, 26.6% between 1980 and 1999, median year 1996 — reads at this distance with a county accent: the shares nearer the centre and the shares at the edge were platted in different decades of the metro's growth. Which band a given Canyon County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
A reader who only had Canyon County's identifying figures would already know its shape: a county of 587 square miles in Idaho, 10 ZIP codes, 5 communities on the record, sitting west of the Boise 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.
One call connects you with an independent local heating and cooling professional serving Canyon County and the Boise metro.
