One county, read on its own ground: Woodbury County, Iowa — 8 communities, 20 ZIP codes, 2 neighbouring counties, inside the Sioux City metro. TempReach USA connects you with an independent local HVAC technician serving the county, and this page is the homework behind the connection.

Start here if you read nothing else: this page covers Woodbury County, Iowa — 873 square miles, 8 listed communities, a centroid southeast of the Sioux City metro's centre. Its climate record, from SIOUX CITY GATEWAY 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.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at SIOUX CITY GATEWAY AP, IA US, the primary metro's station, read here for Woodbury County. The record's shape is 6,860 heating degree days set against 866 cooling degree days, 29.27 inches of precipitation in an average year, 24.6 days reaching 90 degrees or above and 154.1 nights at or below freezing, with an average temperature of 48.5 degrees across the year.
Divide Woodbury County's cold by its coverage and the heating diary sharpens: 20 ZIP codes over 873 square miles, 43.6 square miles per code on average, the codes running from 51004 to 51111. A furnace failure in the code nearest the metro reads differently from one at the county's far edge — not in the fault, which is the same worn igniter or tired blower, but in everything around it: the drive, the house's decade, the odds the system has already been replaced once. The cold itself, 6,860 heating degree days of it, is shared; the ground it is answered on is not.
Distance is the county fact the climate table leaves out. Woodbury County's centroid lies southeast of the Sioux City metro's centre, roughly 21 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 20 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.
The ZIP list is the county's working map. Woodbury County carries 20 codes, running from 51004 through 51052 in the middle of the list to 51111 at its end, and every code on it is a small housing census of its own — the building decades, the system generations, the duct materials of its streets. Heating and cooling work routed by those codes meets the county in slices, and the slices differ more than the county's shared climate record would suggest.
There are 2 counties on Woodbury County's neighbour list, Dakota County, Union County among them, and the list is a reminder that a county page is a slice of a continuous map. The slice is worth keeping separate: this county's land area, its ZIP codes and its communities are its own, and its heating and cooling pressure — the heating profile described above — lands on its own housing. But the slice only makes full sense beside its neighbours, whose pages are linked from this one for exactly that reason.
The county's year divides by load. At one end, 24.6 days at 90 degrees or above pull the cooling season into its long peak; at the other, 154.1 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 48.5 degrees at SIOUX CITY GATEWAY AP, IA US is what those two ends average out to, and 29.27 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Woodbury 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.
Name the ground and the work follows: in Woodbury County, the 8 listed communities — Sioux City, Sergeant Bluff, Dakota City, Moville among them — hold the county's homes, and the homes hold its heating and cooling systems. The largest places supply the steadiest run of calls; the smaller communities supply the long drives and the systems fitted when those places were built. Either way, the county's 873 square miles are not read as one housing stock on this page, because on the ground they are not one: they are these communities, in this order, with these names.
The county's position frames its housing as well. Woodbury County lies southeast of the Sioux City metro's centre, roughly 21 miles out, and the metro's era mix — 46.6% built before 1960, 23.5% between 1960 and 1979, median year 1964 — 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 Woodbury County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
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 Woodbury County's case, across 873 square miles that hold 8 listed communities and 20 ZIP codes, southeast of the Sioux City 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 Woodbury County and the Sioux City metro.
