Newton County in one paragraph: 402 square miles in Indiana, 9 ZIP codes, a heating climate pressure read from the normals at CHICAGO MIDWAY AP, IL US, and housing that answers 5,753 heating degree days against 1,111 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 Newton County's weather the way this page reads it: through the thirty-year normals kept at CHICAGO MIDWAY AP, IL US for the Chicago metro. Those normals give the county 1,111 cooling degree days and 5,753 heating degree days a year, 34.42 inches of precipitation, 19.8 days at 90 degrees or above, 106.3 nights at or below freezing, and an average temperature of 52.1 degrees — the fixed background every system in the county works against.
There is a housing arithmetic under Newton County's heating season. The metro it belongs to built its largest share of homes before 1960 — 38.0% of the stock — with the next share between 1960 and 1979 at 25.6%, around a median build year of 1970. Fitted into those eras, the county's furnaces and heat pumps meet 106.3 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 neighbours frame it as well: McHenry County, Porter County, Will County are among the 12 counties on its neighbour list, and together they form the working ground around Newton County's own 402 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 Newton County is written in five digits. The county's codes begin at 46349 and run to 47964, 9 in total, and between the first and the last sits the county's full spread of ground — 402 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.
Position first: Newton County lies southeast of the Chicago metro's centre, roughly 54 miles from the metro's centre as the map measures it, with McHenry County, Porter County, Will County among the counties around it. Neighbourhood at county scale matters to heating and cooling because systems do not respect the border — the same subdivisions' building decades continue across it, the same cold snaps and heat waves examine both sides in the same night — while each county's page, this one included, keeps the local figures distinct.
The county's year divides by load. At one end, 19.8 days at 90 degrees or above pull the cooling season into its long peak; at the other, 106.3 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 52.1 degrees at CHICAGO MIDWAY AP, IL US is what those two ends average out to, and 34.42 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Newton 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.
The county record for Newton County carries no separate place list — its communities are held in the record through its ZIP codes and its 402 square miles of ground instead, southeast of the Chicago metro's centre. That shape suits the county's service diary: calls here follow addresses and roads rather than town centres, spread across the county's full extent, and the systems they reach were fitted in the decades their individual houses were built. The Chicago metro's larger communities — Chicago, Aurora, Joliet — anchor the region around it; this county's own ground is the quieter share of the map.
Spread the metro's eras over Newton County's own ground and the housing paragraph becomes a map: 402 square miles, 9 ZIP codes at 44.6 square miles per code, and a stock whose largest band was built before 1960 (38.0%), whose pre-1980 share runs to 63.6% and whose post-2000 share runs to 16.6%. The percentages are the metro's; the streets they land on are this county's, and a technician driving from one end of the county to the other drives through the bands in sequence.
Put the county's coverage facts in one place and they read like this: 402 square miles of land in Indiana, 0 listed communities, 9 ZIP codes, 12 neighbouring counties on the record, and a place inside the Chicago 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.
