Start here if you read nothing else: this page covers Larimer County, Colorado — 2,596 square miles, 7 listed communities, a centroid close to the centre of the Fort Collins metro. Its climate record, from NUNN 7 NNE, CO 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.
Read Larimer County's weather the way this page reads it: through the thirty-year normals kept at NUNN 7 NNE, CO US for the Fort Collins metro. Those normals give the county 434 cooling degree days and 6,845 heating degree days a year, 13.4 inches of precipitation, 34.2 days at 90 degrees or above, 183.1 nights at or below freezing, and an average temperature of 47.3 degrees — the fixed background every system in the county works against.
Heating writes this county's HVAC calendar. With 6,845 heating degree days against 434 cooling degree days in the normals recorded at NUNN 7 NNE, CO US, the systems across Larimer County earn their keep in the cold half of the year: furnaces and heat pumps cycling through 183.1 nights at or below freezing, when a breakdown stops being a comfort problem and becomes a household one. The pressure shows up as midwinter failures on the oldest equipment first, and a maintenance calendar that has to be kept in autumn — because by the time the cold arrives, the county's systems are already on stage.
The county's ground shapes the work in one more way: 2,596 square miles is a lot of roofs for a service map to hold, and Larimer County's homes divide between its listed communities — Fort Collins, Loveland, Wellington, Timnath, Estes Park, Laporte — and the roads between them. A technician routed here is working a county, not a street: the drive between calls is part of the diary, and the systems at each end of it were fitted in the decades those communities were built.
A ZIP code in Larimer County is a small climate-and-housing district of its own. The county's 18 codes — 80512, 80513, 80515, 80517 among them — all read the same normals from NUNN 7 NNE, CO US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.
On this coverage map Larimer County stands without a listed neighbour — the record names no adjoining counties beside it inside the Fort Collins metro, so the county's 2,596 square miles are read on their own terms here: their own position close to the centre of the Fort Collins metro, their own ZIP codes, their own share of the metro's climate record. The systems in its homes face the same seasons as the rest of the metro; the ground they face them on is this county's alone.
A year in Larimer County, counted the way a technician counts it, is not twelve months but two workloads and the weeks between them. The first workload is written as 434 cooling degree days, the second as 6,845 heating degree days; 13.4 inches of precipitation fall across both, and the average temperature of 47.3 degrees is simply the figure the two workloads leave behind when they are averaged. The county's heating pressure is whichever workload the count puts first — and the maintenance year is arranged around that ordering.
Larimer County is a county of distinct communities rather than one continuous town: Fort Collins, Loveland, Wellington and Timnath 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 Fort Collins metro, so its communities meet the Fort Collins 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 growth figures deserve their own reading in Larimer County. 37.5% of the Fort Collins metro's homes were built since 2000 — the largest or near-largest band in many of its counties — and those homes are now old enough that their first systems are reaching replacement age together, subdivision by subdivision. Set against them, the 32.7% of the metro's stock that predates 1980 is deep into its second and third systems. One county, two replacement waves running at once, and a maintenance diary that has to serve both.
One way to hold Larimer County in mind is as the local layer of a wider dataset. Above it sits the Fort Collins metro, with its Census housing profile and its NOAA station at NUNN 7 NNE, CO US. At this level sit the county's own numbers — 2,596 square miles, 0 neighbouring counties, 18 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 Larimer County and the Fort Collins metro.
