The short version of this page: Warren County runs to 570 square miles, its weather is the record kept at DES MOINES INTL AP, IA US — 6,178 heating degree days, 1,070 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.
The station for this county's metro is DES MOINES INTL AP, IA US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 36.55 inches a year; the temperature record averages 50.9 degrees, built from 22.0 days at 90 or above and 127.9 nights at or below freezing; the workload totals 6,178 heating degree days and 1,070 cooling degree days. Warren County is read through that record throughout this page.
There is a housing arithmetic under Warren County's heating season. The metro it belongs to built its largest share of homes since 2000 — 33.0% of the stock — with the next share before 1960 at 27.1%, around a median build year of 1984. Fitted into those eras, the county's furnaces and heat pumps meet 127.9 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.
The county's ground shapes the work in one more way: 570 square miles is a lot of roofs for a service map to hold, and Warren County's homes divide between its listed communities — Indianola, Norwalk — 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 Warren County is a small climate-and-housing district of its own. The county's 12 codes — 50001, 50047, 50118, 50125 among them — all read the same normals from DES MOINES INTL AP, IA 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.
The counties around Warren County include Jasper County, Madison County, Polk County, and the whole group shares the Des Moines metro's climate record from DES MOINES INTL AP, IA US. What the neighbours do not share is this county's ground: 570 square miles, 12 ZIP codes, a centroid southeast of the Des Moines metro's centre. Service patterns cross the county line freely — a cold week fills diaries on both sides of it — but the mix of housing and systems on each side is its own, which is why each county in the group carries its own page.
Extremes, not averages, fill Warren County's emergency diary, and the record names them precisely: 22.0 days a year at 90 degrees or above, 127.9 nights at or below freezing. Between those figures sits the ordinary year — an average of 50.9 degrees, 36.55 inches of rain — in which systems mostly age quietly. The two ends are when ageing becomes failure, which is why the county's dominant heating pressure, the taller of its two peaks, sets the rhythm of its maintenance year as well.
Warren County's named places — Indianola, Norwalk — anchor a county that is mostly ground between names: 570 square miles, 12 ZIP codes, and housing that follows the roads more than the towns. The wider metro it belongs to is anchored by Des Moines (212,464 residents) and Ankeny, but this county's own diary is quieter and more spread out: individual systems in individual houses, ageing on the schedule of the decade each house was built, from the named communities outward.
Census figures give Warren County's heating and cooling its proportions. The metro it belongs to counts 308,705 housing units across 289,451 households, 69.5% of them owner-occupied, and the era mix runs 27.1% before 1960, 19.9% from 1960 to 1979, 19.9% from 1980 to 1999 and 33.0% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Warren County street, built forty years apart, can need entirely different conversations from the same technician.
Put the county's coverage facts in one place and they read like this: 570 square miles of land in Iowa, 2 listed communities, 12 ZIP codes, 5 neighbouring counties on the record, and a place inside the Des Moines 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 Warren County and the Des Moines metro.
