In brief: 594 square miles of Kansas, a climate read from LEES SUMMIT MUNI AP, MO US's normals, and a heating pressure as the county's dominant one — 4,786 heating degree days set against 1,446 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 Linn County.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at LEES SUMMIT MUNI AP, MO US, the primary metro's station, read here for Linn County. The record's shape is 4,786 heating degree days set against 1,446 cooling degree days, 38.34 inches of precipitation in an average year, 37.7 days reaching 90 degrees or above and 96.3 nights at or below freezing, with an average temperature of 55.7 degrees across the year.
There is a housing arithmetic under Linn County's heating season. The metro it belongs to built its largest share of homes before 1960 — 25.9% of the stock — with the next share between 1960 and 1979 at 25.4%, around a median build year of 1979. Fitted into those eras, the county's furnaces and heat pumps meet 96.3 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: Clay County, Clinton County, Jackson County are among the 13 counties on its neighbour list, and together they form the working ground around Linn County's own 594 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 Linn County is written in five digits. The county's codes begin at 66010 and run to 66767, 7 in total, and between the first and the last sits the county's full spread of ground — 594 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.
Linn County sits alongside Clay County, Clinton County, Jackson County in the Kansas City area — 13 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 Linn County's own share of the picture separate.
The county's year divides by load. At one end, 37.7 days at 90 degrees or above pull the cooling season into its long peak; at the other, 96.3 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 55.7 degrees at LEES SUMMIT MUNI AP, MO US is what those two ends average out to, and 38.34 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Linn 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.
Linn County is recorded by land and code rather than by named places: 594 square miles in Kansas, lying southwest of the Kansas City metro's centre, roughly 59 miles from the metro's centre as the map measures it. Its households sit inside the Kansas City 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.
Age is the county's second climate. The Kansas City metro's median home was built in 1979, and 51.3% of its homes predate 1980 — in Linn 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, 23.5% 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.
Coverage, for Linn County, is a set of overlapping maps. The land map is 594 square miles. The address map is 7 ZIP codes and 0 listed communities. The service map is the Kansas City metro, whose coverage the county sits inside — southwest of the Kansas City metro's centre, roughly 59 miles from its centre. The weather map is one station's record, kept at LEES SUMMIT MUNI AP, MO US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.
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 Linn County and the Kansas City metro.
