Madison County in one paragraph: 561 square miles in Iowa, 12 ZIP codes, a heating climate pressure read from the normals at DES MOINES INTL AP, IA US, and housing that answers 6,178 heating degree days against 1,070 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.
Read Madison County's weather the way this page reads it: through the thirty-year normals kept at DES MOINES INTL AP, IA US for the Des Moines metro. Those normals give the county 1,070 cooling degree days and 6,178 heating degree days a year, 36.55 inches of precipitation, 22.0 days at 90 degrees or above, 127.9 nights at or below freezing, and an average temperature of 50.9 degrees — the fixed background every system in the county works against.
Count the cold from the ground up in Madison County and the figures arrange themselves: 6,178 heating degree days against 1,070 cooling degree days, 127.9 freezing nights in an average year, and a housing stock spread over 561 square miles whose heating plant was fitted in the decades its communities were built. The diary that follows is written street by street — ignition and exchanger work where the stock is oldest, control and sensor work where it is newest — and the county's technicians read the address before they read the fault.
One more county fact belongs in the record: position. Madison County sits at 41.330622, -94.015184 on the map — the centroid of a county whose communities spread across 561 square miles of Iowa. 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.
12 ZIP codes reach into Madison County's 561 square miles, among them 50033, 50061, 50070, 50072 — an average of 46.8 square miles of county ground per code. The codes are more than a mailing grid here: they are how the county's service ground divides in practice, each code holding its own mix of housing eras, its own streets of systems ageing on their own schedules. A call in one code and a call in the next can be the same fault in different decades of house.
Read the map around Madison County and a working region appears: Jasper County, Polk County, Warren County, Dallas County are the neighbouring names at the head of its list of 5, and together these counties form the ground a local technician actually covers. The county line decides which page describes a home; it does not decide the weather the home's system faces, the decade its street was built in, or the season its diary fills. Those are regional — and the region, on this site, is a set of county pages that link to one another, as the cards below do.
Two numbers organise Madison County's heating and cooling year: 6,178 and 1,070, the heating and cooling degree days in the normals at DES MOINES INTL AP, IA US. Whichever runs larger decides the county's dominant pressure — here, a heating one — and with it the season a household should prepare for first. The supporting figures fill in the texture: 50.9 degrees as the year's average temperature, 22.0 hot days, 127.9 freezing nights, 36.55 inches of precipitation. Every paragraph on this page is, in the end, a reading of those six numbers on this county's ground.
Madison County is recorded by land and code rather than by named places: 561 square miles in Iowa, lying southwest of the Des Moines metro's centre, roughly 20 miles from the metro's centre as the map measures it. Its households sit inside the Des Moines metro's coverage and share its climate record, but their heating and cooling diary is written at address level — a system in a house on a county road, ageing on its own house's schedule. A county page built from a place list would have little to say here; a page built from the ground itself has the county as it is.
The county's position frames its housing as well. Madison County lies southwest of the Des Moines metro's centre, roughly 20 miles out, and the metro's era mix — 33.0% built since 2000, 27.1% before 1960, median year 1984 — 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 Madison County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
The county is worth a page of its own because its facts do not reduce to its metro's. The Des Moines metro supplies the climate station and the housing profile, but Madison County supplies everything at ground level: 561 square miles, its own communities and codes, its own neighbours — Jasper County, Polk County, Warren County among the 5 on its list — and its own position, southwest of the Des Moines metro's centre. The metro page and this page link to each other because neither half of that picture stands well without the other.
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 Madison County and the Des Moines metro.
