Oldham County in one paragraph: 1,501 square miles in Texas, 2 ZIP codes, a heating climate pressure read from the normals at AMARILLO, TX US, and housing that answers 3,872 heating degree days against 1,609 cooling degree days a year. TempReach USA is a referral service, not an HVAC company — one call connects you with an independent local HVAC technician serving this county.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at AMARILLO, TX US, the primary metro's station, read here for Oldham County. The record's shape is 3,872 heating degree days set against 1,609 cooling degree days, 19.66 inches of precipitation in an average year, 72.4 days reaching 90 degrees or above and 107.9 nights at or below freezing, with an average temperature of 58.7 degrees across the year.
Read the climate record and the county's pressure names itself. Heating degree days outnumber cooling degree days at AMARILLO, TX US, and the lived version of that statistic is a housing stock whose furnaces and heat pumps run the long season while its cooling takes the short one. Across Oldham County's 1,501 square miles — from Vega to the county's edge communities — the pattern repeats: systems sized for the cold, maintained for the cold, and replaced, when their time comes, with the cold in mind first.
Set the county inside its metro and the picture completes. Oldham County answers to the Amarillo metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 1 communities, 2 ZIP codes, one county's worth of systems ageing under the record kept at AMARILLO, TX US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
2 ZIP codes reach into Oldham County's 1,501 square miles, among them 79001, 79092 — an average of 750.3 square miles of county ground per code. The codes are more than a mailing grid here: they are how the county's service ground divides in practice, each code holding its own mix of housing eras, its own streets of systems ageing on their own schedules. A call in one code and a call in the next can be the same fault in different decades of house.
Position first: Oldham County lies northwest of the Amarillo metro's centre, roughly 45 miles from the metro's centre as the map measures it, with Armstrong County, Carson County, Potter 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.
A year in Oldham 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 1,609 cooling degree days, the second as 3,872 heating degree days; 19.66 inches of precipitation fall across both, and the average temperature of 58.7 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.
A short place list shapes Oldham County's service pattern in a specific way. With Vega the named communities on its record, the county's calls divide between those places and the unincorporated ground around them — and the ground is the larger share of its 1,501 square miles. Technicians routed here plan for distance as much as for faults: the drive between calls crosses the county's position northwest of the Amarillo metro's centre, and the systems at each end belong to different building decades even when the drive is short.
Age is the county's second climate. The Amarillo metro's median home was built in 1976, and 55.9% of its homes predate 1980 — in Oldham 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, 24.6% 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.
A reader who only had Oldham County's identifying figures would already know its shape: a county of 1,501 square miles in Texas, 2 ZIP codes, 1 communities on the record, sitting northwest of the Amarillo 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.
One call connects you with an independent local heating and cooling professional serving Oldham County and the Amarillo metro.
