Start here if you read nothing else: this page covers Guthrie County, Iowa — 591 square miles, 0 listed communities, a centroid northwest of the Des Moines metro's centre. Its climate record, from DES MOINES INTL AP, IA 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.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at DES MOINES INTL AP, IA US, the station for the Des Moines metro this county belongs to. An average year there brings 6,178 heating degree days, 1,070 cooling degree days, 36.55 inches of precipitation, 22.0 days at 90 degrees or above and 127.9 nights at or below freezing, around an average temperature of 50.9 degrees.
There is a second heating pressure in Guthrie County that the degree days only imply: repetition across distance. A cold snap does not visit one street here; it visits all 10 of the county's ZIP codes in the same night, from the communities nearest the metro's centre to the edge of its 591 square miles, and every ageing system in that ground is examined by the same low temperature at the same hour. That simultaneity — many systems, one weather, a county's worth of roads between the calls — is what makes the cold weeks in a heating-profile county feel different from the same weeks in a city.
The county's neighbours frame it as well: Jasper County, Madison County, Polk County are among the 5 counties on its neighbour list, and together they form the working ground around Guthrie County's own 591 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.
Routing in Guthrie County is written in five digits. The county's codes begin at 50002 and run to 50277, 10 in total, and between the first and the last sits the county's full spread of ground — 591 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.
Guthrie County sits alongside Jasper County, Madison County, Polk County in the Des Moines area — 5 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 Guthrie County's own share of the picture separate.
The county's year divides by load. At one end, 22.0 days at 90 degrees or above pull the cooling season into its long peak; at the other, 127.9 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 50.9 degrees at DES MOINES INTL AP, IA US is what those two ends average out to, and 36.55 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Guthrie 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.
Hold Guthrie County up against its own neighbours and the missing place list stops looking like a gap. Jasper County, Madison County, Polk County are among the 5 counties around it; some of them are lists of named towns, this one is 591 square miles of ground lying northwest of the Des Moines metro's centre, roughly 37 miles out. Its communities exist — people live in them, heat them, cool them — but the record reaches them through the county's ZIP codes rather than through names, and this page follows the record's way of seeing.
Age is the county's second climate. The Des Moines metro's median home was built in 1984, and 47.0% of its homes predate 1980 — in Guthrie County, that share is the older districts and the long-settled communities, where ductwork from an earlier equipment era still serves replacement systems. The newer share, 33.0% built since 2000, concentrates in the county's growth edges. The service diary divides along that line: deep equipment-and-duct conversations at the old end, first-replacement and control conversations at the new one.
There is a reason the coverage on this page is described county-first. Heating and cooling demand is generated house by house, and houses sit in counties: in Guthrie County's case, across 591 square miles that hold 0 listed communities and 10 ZIP codes, northwest of the Des Moines metro's centre. The metro frame matters — the station, the housing eras, the problem ranking all come from it — but the county is where the frame touches the ground, and the ground is where the systems are.
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 Guthrie County and the Des Moines metro.
