In brief: 533 square miles of Kansas, a climate read from TOPEKA MUNI AP, KS US's normals, and a heating pressure as the county's dominant one — 4,860 heating degree days set against 1,534 cooling degree days in an average year. TempReach USA does not do the work itself; it is a referral service, and one call connects you with an independent local HVAC technician serving Jefferson County.
Before the narrative, the numbers themselves, because everything after them is commentary: at TOPEKA MUNI AP, KS US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 49.6 days at 90 degrees or above, 113.9 nights at or below freezing, 36.53 inches of precipitation and degree-day totals of 4,860 heating against 1,534 cooling. Spread over 533 square miles, with the county's centroid northeast of the Topeka metro's centre and roughly 24 miles from the centre it is measured against, that record is Jefferson County's working climate.
Heating pressure in Jefferson County can be counted in codes as well as in degree days. From 66054 through 66073 to 66512, the county's 9 ZIP codes divide 533 square miles of housing that one cold record — 4,860 heating degree days, 113.9 freezing nights, kept at TOPEKA MUNI AP, KS US — examines in a single night. The fault is usually an old one, an igniter or an exchanger at the end of its winters; the ground it is found on, code by code, is what makes the diary this county's.
The county's neighbours frame it as well: Jackson County, Osage County, Shawnee County are among the 4 counties on its neighbour list, and together they form the working ground around Jefferson County's own 533 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 Jefferson County is written in five digits. The county's codes begin at 66054 and run to 66512, 9 in total, and between the first and the last sits the county's full spread of ground — 533 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.
Jefferson County sits alongside Jackson County, Osage County, Shawnee County in the Topeka area — 4 neighbouring counties share its coverage map in all, and the borders between them are lines on a map rather than changes in the weather. The same station record travels across those borders, the same housing decades appear on both sides, and a technician's ground here is really the cluster: this county and its neighbours, read together, with this page keeping Jefferson County's own share of the picture separate.
There is a geography to Jefferson County's seasons that the totals flatten. The county lies northeast of the Topeka metro's centre, roughly 24 miles from the centre the record is measured against, and its 533 square miles do not meet a hot week or a cold snap in one voice: the ground nearer the metro and the ground at the county's far edge live the same 49.6 hot days and 113.9 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Name the ground and the work follows: in Jefferson County, the 3 listed communities — Valley Falls, Oskaloosa, Perry among them — hold the county's homes, and the homes hold its heating and cooling systems. The largest places supply the steadiest run of calls; the smaller communities supply the long drives and the systems fitted when those places were built. Either way, the county's 533 square miles are not read as one housing stock on this page, because on the ground they are not one: they are these communities, in this order, with these names.
Census figures give Jefferson County's heating and cooling its proportions. The metro it belongs to counts 104,931 housing units across 95,996 households, 70.2% of them owner-occupied, and the era mix runs 33.3% before 1960, 29.7% from 1960 to 1979, 22.4% from 1980 to 1999 and 14.6% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Jefferson County street, built forty years apart, can need entirely different conversations from the same technician.
The county is worth a page of its own because its facts do not reduce to its metro's. The Topeka metro supplies the climate station and the housing profile, but Jefferson County supplies everything at ground level: 533 square miles, its own communities and codes, its own neighbours — Jackson County, Osage County, Shawnee County among the 4 on its list — and its own position, northeast of the Topeka 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 Jefferson County and the Topeka metro.
