The short version of this page: Harrison County runs to 697 square miles, its weather is the record kept at OMAHA EPPLEY AIRFIELD, NE US — 5,833 heating degree days, 1,294 cooling degree days — and its systems live under a heating pressure. One call to TempReach USA, a referral service rather than an HVAC company, connects you with an independent local HVAC technician serving the county.
Before the narrative, the numbers themselves, because everything after them is commentary: at OMAHA EPPLEY AIRFIELD, NE US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 33.1 days at 90 degrees or above, 134.6 nights at or below freezing, 31.86 inches of precipitation and degree-day totals of 5,833 heating against 1,294 cooling. Spread over 697 square miles, with the county's centroid northeast of the Omaha metro's centre and roughly 31 miles from the centre it is measured against, that record is Harrison County's working climate.
There is a housing arithmetic under Harrison County's heating season. The metro it belongs to built its largest share of homes before 1960 — 27.2% of the stock — with the next share since 2000 at 26.3%, around a median build year of 1978. Fitted into those eras, the county's furnaces and heat pumps meet 134.6 freezing nights at very different ages, and the heating diary divides accordingly: deep repair conversations in the older bands, first-replacement conversations in the newer ones.
Distance is the county fact the climate table leaves out. Harrison County's centroid lies northeast of the Omaha metro's centre, roughly 31 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 10 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: 51529, 51545 and 51546 are the first codes on Harrison County's list of 10, spread across its 697 square miles in Iowa. 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 Harrison County's figures. Its 697 square miles sit inside a wider spread of county ground — Cass County, Douglas County, Mills County are among the 7 neighbours on its record — and its position northeast of the Omaha 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.
A year in Harrison 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 1,294 cooling degree days, the second as 5,833 heating degree days; 31.86 inches of precipitation fall across both, and the average temperature of 52.4 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.
The codes carry the community story in Harrison County: 10 of them, from 51529 through to 51579, at 69.7 square miles per code across the county's 697 square miles. Nobody here describes a call by its town, because the record gives the county no towns to describe it by; they describe it by its code and its road. The housing behind those codes was still built decade by decade, and the systems still age decade by decade — the county simply files the diary by ZIP instead of by place.
The housing behind Harrison County's systems is the Omaha metro's housing, read at county scale. The largest single share of the metro's homes was built before 1960 — 27.2% of the stock — with 52.3% of homes predating 1980 and 26.3% arriving since 2000, around a median build year of 1978. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to before 1960 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.
Put the county's coverage facts in one place and they read like this: 697 square miles of land in Iowa, 0 listed communities, 10 ZIP codes, 7 neighbouring counties on the record, and a place inside the Omaha metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
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 Harrison County and the Omaha metro.
