Jasper County covers 730 square miles in Iowa. Its climate is read from the normals recorded at DES MOINES INTL AP, IA US — 6,178 heating degree days against 1,070 cooling degree days — and its dominant pressure is a heating one. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving the county.
Climate on this page is not a national average wearing a county's name. It is the specific record at DES MOINES INTL AP, IA US: 50.9 degrees as the average temperature, 36.55 inches of precipitation, 22.0 hot days and 127.9 freezing nights in the average year, 6,178 heating degree days against 1,070 cooling degree days. Jasper County — 730 square miles, 12 ZIP codes, 1 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
Jasper County is heating country by the numbers: 6,178 heating degree days a year, 127.9 freezing nights, and homes spread over 730 square miles all asking their systems the same question on the same January night. The cooling half of the equipment matters — 1,070 cooling degree days is not nothing — but it is the heating load that decides which systems fail, and when. Local technicians read the county that way: autumn tune-ups, honest conversations about ageing furnaces and heat exchangers, and vans stocked for the cold weeks.
Set the county inside its metro and the picture completes. Jasper County answers to the Des Moines metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 1 communities, 12 ZIP codes, one county's worth of systems ageing under the record kept at DES MOINES INTL AP, IA US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
There is a scale fact hidden in Jasper County's ZIP codes: 12 codes across 730 square miles works out to 60.9 square miles per code, which makes a service call here a matter of ground as well as of systems. The codes on the metro-facing side of the county — the county sits northeast of the Des Moines metro's centre — and the codes at its far edge hold different ground, but both ends ask the same climate questions of their heating and cooling, at different distances.
There are 5 counties on Jasper County's neighbour list, Polk County, Warren County, Dallas 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 precipitation figure earns its place in Jasper County's record: 36.55 inches a year at DES MOINES INTL AP, IA US, falling through both the cooling months and the heating ones. Rain loads condensate systems in summer, tests outdoor units and venting in winter, and keeps the ground around the county's 12 ZIP codes cycling between wet and dry in a way that shows up in crawl spaces and condensate lines. Set beside 22.0 hot days and 127.9 freezing nights, it completes the picture of what the county's equipment actually lives in.
Read Jasper County through its record and two facts stand together: its named communities are Newton, and its land runs to 730 square miles. Between those facts sits the county's real housing — homes in the named places, homes along the roads the record does not name, all of them heating and cooling under the climate recorded at DES MOINES INTL AP, IA US. This page keeps both facts in view, because a county page that only described its named places would miss most of the county it is about.
The growth figures deserve their own reading in Jasper County. 33.0% of the Des Moines metro's homes were built since 2000 — the largest or near-largest band in many of its counties — and those homes are now old enough that their first systems are reaching replacement age together, subdivision by subdivision. Set against them, the 47.0% of the metro's stock that predates 1980 is deep into its second and third systems. One county, two replacement waves running at once, and a maintenance diary that has to serve both.
A reader who only had Jasper County's identifying figures would already know its shape: a county of 730 square miles in Iowa, 12 ZIP codes, 1 communities on the record, sitting northeast of the Des Moines metro's centre. What the figures cannot say alone is how the ground feels to work — the drives between calls, the mix of decades in the housing, the season that runs taller — and that is what the rest of this page is for, section by section.
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.
