Shelby County covers 753 square miles in Tennessee. Its climate is read from the normals recorded at MEMPHIS INTL AP, TN US — 2,875 heating degree days against 2,314 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.
Before the narrative, the numbers themselves, because everything after them is commentary: at MEMPHIS INTL AP, TN US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 72.1 days at 90 degrees or above, 44.4 nights at or below freezing, 54.94 inches of precipitation and degree-day totals of 2,875 heating against 2,314 cooling. Spread over 753 square miles, with the county's centroid north of the Memphis metro's centre and roughly 15 miles from the centre it is measured against, that record is Shelby County's working climate.
The neighbours tell part of Shelby County's heating story: Benton County, Crittenden County, DeSoto County are among the counties around it, all reading the same record at MEMPHIS INTL AP, TN US, all filling their diaries in the same cold weeks. What separates this county's share is its own ground — 753 square miles lying north of the Memphis metro's centre, roughly 15 miles from the metro's centre — and its own housing, fitted across the decades its communities were built. The season is regional; the failures are local, one system at a time, at addresses only this county has.
The county's neighbours frame it as well: Benton County, Crittenden County, DeSoto County are among the 8 counties on its neighbour list, and together they form the working ground around Shelby County's own 753 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.
A ZIP code in Shelby County is a small climate-and-housing district of its own. The county's 38 codes — 38002, 38016, 38017, 38018 among them — all read the same normals from MEMPHIS INTL AP, TN US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.
Position first: Shelby County lies north of the Memphis metro's centre, roughly 15 miles from the metro's centre as the map measures it, with Benton County, Crittenden County, DeSoto 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.
Extremes, not averages, fill Shelby County's emergency diary, and the record names them precisely: 72.1 days a year at 90 degrees or above, 44.4 nights at or below freezing. Between those figures sits the ordinary year — an average of 63.4 degrees, 54.94 inches of rain — in which systems mostly age quietly. The two ends are when ageing becomes failure, which is why the county's dominant heating pressure, the taller of its two peaks, sets the rhythm of its maintenance year as well.
There is a practical reason this page names Shelby County's communities one by one. A heating or cooling system belongs to a house, a house belongs to a community, and the community's building decade is the strongest single clue to what the system will need — the 7 places recorded here, from Memphis through Germantown and beyond, each carry that clue in their streets. The metro data on the Memphis page describes the whole region; this list is where the description becomes local.
Age is the county's second climate. The Memphis metro's median home was built in 1982, and 47.1% of its homes predate 1980 — in Shelby 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, 23.4% 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 Shelby County, is a set of overlapping maps. The land map is 753 square miles. The address map is 38 ZIP codes and 7 listed communities. The service map is the Memphis metro, whose coverage the county sits inside — north of the Memphis metro's centre, roughly 15 miles from its centre. The weather map is one station's record, kept at MEMPHIS INTL AP, TN 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 Shelby County and the Memphis metro.
