Callahan County in one paragraph: 899 square miles in Texas, 4 ZIP codes, a cooling climate pressure read from the normals at ABILENE RGNL AP, TX US, and housing that answers 2,319 heating degree days against 2,696 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.
Climate on this page is not a national average wearing a county's name. It is the specific record at ABILENE RGNL AP, TX US: 66.0 degrees as the average temperature, 25.24 inches of precipitation, 102.4 hot days and 47.7 freezing nights in the average year, 2,319 heating degree days against 2,696 cooling degree days. Callahan County — 899 square miles, 4 ZIP codes, 4 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
Cooling pressure in Callahan County can also be counted in ground rather than in degrees. The county spreads its homes over 899 square miles — 4 ZIP codes at 224.8 square miles per code, running from 76443 to 79510 — and every one of those codes asks the same July question of systems fitted in different building decades. The degree days, 2,696 of them against 2,319 heating degree days, set the season's size; the codes and the decades set the order in which it is answered.
Distance is the county fact the climate table leaves out. Callahan County's centroid lies southeast of the Abilene metro's centre, roughly 22 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 4 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
4 ZIP codes reach into Callahan County's 899 square miles, among them 76443, 76469, 79504, 79510 — an average of 224.8 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: Callahan County lies southeast of the Abilene metro's centre, roughly 22 miles from the metro's centre as the map measures it, with Jones County, Taylor 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 service calendar for Callahan County can be written straight from its station record. Spring belongs to the cooling plant: 2,696 cooling degree days are coming, and the systems that will carry them are checked before the first of the 102.4 hot days arrives. Autumn belongs to the heating plant, ahead of 2,319 heating degree days and 47.7 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at ABILENE RGNL AP, TX US does not change much year to year, which is what makes the calendar worth keeping.
There is a practical reason this page names Callahan 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 4 places recorded here, from Clyde through Putnam and beyond, each carry that clue in their streets. The metro data on the Abilene page describes the whole region; this list is where the description becomes local.
The growth figures deserve their own reading in Callahan County. 20.8% of the Abilene metro's homes were built since 2000 — the largest or near-largest band in many of its counties — and those homes are now old enough that their first systems are reaching replacement age together, subdivision by subdivision. Set against them, the 54.9% of the metro's stock that predates 1980 is deep into its second and third systems. One county, two replacement waves running at once, and a maintenance diary that has to serve both.
A reader who only had Callahan County's identifying figures would already know its shape: a county of 899 square miles in Texas, 4 ZIP codes, 4 communities on the record, sitting southeast of the Abilene 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.
