Denver County covers 153 square miles in Colorado. Its climate is read from the normals recorded at DENVER CENTENNIAL AP, CO US — 6,014 heating degree days against 636 cooling degree days — and its dominant pressure is a heating one. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving the county.
The station for this county's metro is DENVER CENTENNIAL AP, CO US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 15.02 inches a year; the temperature record averages 50.2 degrees, built from 31.7 days at 90 or above and 154.7 nights at or below freezing; the workload totals 6,014 heating degree days and 636 cooling degree days. Denver County is read through that record throughout this page.
Read the climate record and the county's pressure names itself. Heating degree days outnumber cooling degree days at DENVER CENTENNIAL AP, CO US, and the lived version of that statistic is a housing stock whose furnaces and heat pumps run the long season while its cooling takes the short one. Across Denver County's 153 square miles — from Denver to the county's edge communities — the pattern repeats: systems sized for the cold, maintained for the cold, and replaced, when their time comes, with the cold in mind first.
Distance is the county fact the climate table leaves out. Denver County's centroid lies north of the Denver metro's centre, roughly 12 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 31 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
Count the coverage from the codes upward: 80202, 80203 and 80204 are the first codes on Denver County's list of 31, spread across its 153 square miles in Colorado. 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.
Neighbouring counties are the honest context for Denver County's figures. Its 153 square miles sit inside a wider spread of county ground — Broomfield County, Clear Creek County, Douglas County are among the 9 neighbours on its record — and its position north of the Denver metro's centre places it on its own side of that spread. A system near the county's edge may be closer to a neighbouring county's centre than to its own; the pages are organised by county because the data is, and the links between them carry the rest of the picture.
There is a geography to Denver County's seasons that the totals flatten. The county lies north of the Denver metro's centre, roughly 12 miles from the centre the record is measured against, and its 153 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 31.7 hot days and 154.7 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
The county record names Denver among Denver County's communities — a short list, and an honest one: much of the county's housing sits outside its named places, along the roads and in the settlements between them, across 153 square miles of Colorado. The heating and cooling diary follows that pattern. Calls cluster where the named communities cluster, then spread out along the county's ZIP codes, and the systems at the far ends of those drives were fitted in the decades their houses were built, community or no community.
The housing behind Denver County's systems is the Denver metro's housing, read at county scale. The largest single share of the metro's homes was built since 2000 — 30.6% of the stock — with 42.1% of homes predating 1980 and 30.6% arriving since 2000, around a median build year of 1986. 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 Denver County in mind is as the local layer of a wider dataset. Above it sits the Denver metro, with its Census housing profile and its NOAA station at DENVER CENTENNIAL AP, CO US. At this level sit the county's own numbers — 153 square miles, 9 neighbouring counties, 31 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.
One call connects you with an independent local heating and cooling professional serving Denver County and the Denver metro.
