Weld County in one paragraph: 3,985 square miles in Colorado, 35 ZIP codes, a heating climate pressure read from the normals at NUNN 7 NNE, CO US, and housing that answers 6,845 heating degree days against 434 cooling degree days a year. TempReach USA is a referral service, not an HVAC company — one call connects you with an independent local HVAC technician serving this county.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at NUNN 7 NNE, CO US, the primary metro's station, read here for Weld County. The record's shape is 6,845 heating degree days set against 434 cooling degree days, 13.4 inches of precipitation in an average year, 34.2 days reaching 90 degrees or above and 183.1 nights at or below freezing, with an average temperature of 47.3 degrees across the year.
Weld County is heating country by the numbers: 6,845 heating degree days a year, 183.1 freezing nights, and homes spread over 3,985 square miles all asking their systems the same question on the same January night. The cooling half of the equipment matters — 434 cooling degree days is not nothing — but it is the heating load that decides which systems fail, and when. Local technicians read the county that way: autumn tune-ups, honest conversations about ageing furnaces and heat exchangers, and vans stocked for the cold weeks.
One more county fact belongs in the record: position. Weld County sits at 40.555961, -104.383666 on the map — the centroid of a county whose communities spread across 3,985 square miles of Colorado. 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.
Routing in Weld County is written in five digits. The county's codes begin at 80504 and run to 80754, 35 in total, and between the first and the last sits the county's full spread of ground — 3,985 square miles from the metro-facing edge to the far side. A technician's week here is a tour of those codes, and the tour is also a tour of the county's building history, because each code's systems were largely fitted when that code's streets were built.
A county with no neighbours on its record is a simpler map: Weld County, 3,985 square miles of Colorado, sitting close to the centre of the Greeley metro and carrying the Greeley metro's coverage at its edge. Nothing about the work simplifies with the map — the county's housing still spans its building decades, its systems still answer the full degree-day record — but the page can keep its whole attention on one county's ground, which is what it does.
The precipitation figure earns its place in Weld County's record: 13.4 inches a year at NUNN 7 NNE, CO US, falling through both the cooling months and the heating ones. Rain loads condensate systems in summer, tests outdoor units and venting in winter, and keeps the ground around the county's 35 ZIP codes cycling between wet and dry in a way that shows up in crawl spaces and condensate lines. Set beside 34.2 hot days and 183.1 freezing nights, it completes the picture of what the county's equipment actually lives in.
There is a practical reason this page names Weld County's communities one by one. A heating or cooling system belongs to a house, a house belongs to a community, and the community's building decade is the strongest single clue to what the system will need — the 14 places recorded here, from Greeley through Evans and beyond, each carry that clue in their streets. The metro data on the Greeley page describes the whole region; this list is where the description becomes local.
Census figures give Weld County's heating and cooling its proportions. The metro it belongs to counts 125,033 housing units across 120,019 households, 75.5% of them owner-occupied, and the era mix runs 12.0% before 1960, 18.8% from 1960 to 1979, 19.8% from 1980 to 1999 and 49.4% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Weld County street, built forty years apart, can need entirely different conversations from the same technician.
A reader who only had Weld County's identifying figures would already know its shape: a county of 3,985 square miles in Colorado, 35 ZIP codes, 14 communities on the record, sitting close to the centre of the Greeley metro. 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 Weld County and the Greeley metro.
