The short version of this page: Jasper County runs to 639 square miles, its weather is the record kept at JOPLIN REGIONAL AIRPORT, MO US — 4,120 heating degree days, 1,650 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.
Read Jasper County's weather the way this page reads it: through the thirty-year normals kept at JOPLIN REGIONAL AIRPORT, MO US for the Joplin metro. Those normals give the county 1,650 cooling degree days and 4,120 heating degree days a year, 45.58 inches of precipitation, 52.9 days at 90 degrees or above, 86.9 nights at or below freezing, and an average temperature of 58.1 degrees — the fixed background every system in the county works against.
Divide Jasper County's cold by its coverage and the heating diary sharpens: 15 ZIP codes over 639 square miles, 42.6 square miles per code on average, the codes running from 64755 to 64870. A furnace failure in the code nearest the metro reads differently from one at the county's far edge — not in the fault, which is the same worn igniter or tired blower, but in everything around it: the drive, the house's decade, the odds the system has already been replaced once. The cold itself, 4,120 heating degree days of it, is shared; the ground it is answered on is not.
The county's neighbours frame it as well: Cherokee County, Newton County are among the 2 counties on its neighbour list, and together they form the working ground around Jasper County's own 639 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.
The ZIP list is the county's working map. Jasper County carries 15 codes, running from 64755 through 64836 in the middle of the list to 64870 at its end, and every code on it is a small housing census of its own — the building decades, the system generations, the duct materials of its streets. Heating and cooling work routed by those codes meets the county in slices, and the slices differ more than the county's shared climate record would suggest.
Neighbouring counties are the honest context for Jasper County's figures. Its 639 square miles sit inside a wider spread of county ground — Cherokee County, Newton County are among the 2 neighbours on its record — and its position east of the Joplin 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 Jasper 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 1,650 cooling degree days, the second as 4,120 heating degree days; 45.58 inches of precipitation fall across both, and the average temperature of 58.1 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 county's place list tells its own story. Joplin (52,218 residents) is the largest of the 8 communities the record names for Jasper County, with Carthage (15,513 residents) behind it and Webb City and Carl Junction further down the list. A technician working this county works all of those places in a single week, and the systems change character with the address: the era a community was built in decides whether the call is about an ageing furnace, a condenser at the end of its summers, or ductwork that predates the equipment it now serves.
Age is the county's second climate. The Joplin metro's median home was built in 1982, and 47.5% of its homes predate 1980 — in Jasper County, that share is the older districts and the long-settled communities, where ductwork from an earlier equipment era still serves replacement systems. The newer share, 27.1% built since 2000, concentrates in the county's growth edges. The service diary divides along that line: deep equipment-and-duct conversations at the old end, first-replacement and control conversations at the new one.
Put the county's coverage facts in one place and they read like this: 639 square miles of land in Missouri, 8 listed communities, 15 ZIP codes, 2 neighbouring counties on the record, and a place inside the Joplin 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 Jasper County and the Joplin metro.
