Caldwell County covers 545 square miles in Texas. Its climate is read from the normals recorded at AUSTIN BERGSTROM AP, TX US — 1,718 heating degree days against 2,996 cooling degree days — and its dominant pressure is a cooling 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 AUSTIN BERGSTROM AP, TX US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 123.5 days at 90 degrees or above, 33.0 nights at or below freezing, 35.57 inches of precipitation and degree-day totals of 1,718 heating against 2,996 cooling. Spread over 545 square miles, with the county's centroid south of the Austin metro's centre and roughly 24 miles from the centre it is measured against, that record is Caldwell County's working climate.
The cooling load also has an address pattern in Caldwell County. Its 7 ZIP codes divide 545 square miles into service ground where the same July afternoon lands on subdivisions, older streets and edge communities at once, and the county's position — south of the Austin metro's centre, roughly 24 miles from the metro's centre — decides how much of the Austin metro's heat arrives with city intensity and how much arrives softened by open ground. The systems answer accordingly: one long cooling season, read ZIP by ZIP, with the oldest condensers carrying the heaviest share of it.
Set the county inside its metro and the picture completes. Caldwell County answers to the Austin metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 0 communities, 7 ZIP codes, one county's worth of systems ageing under the record kept at AUSTIN BERGSTROM AP, TX US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
Routing in Caldwell County is written in five digits. The county's codes begin at 78616 and run to 78661, 7 in total, and between the first and the last sits the county's full spread of ground — 545 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.
Neighbouring counties are the honest context for Caldwell County's figures. Its 545 square miles sit inside a wider spread of county ground — Bastrop County, Hays County, Travis County are among the 4 neighbours on its record — and its position south of the Austin metro's centre places it on its own side of that spread. A system near the county's edge may be closer to a neighbouring county's centre than to its own; the pages are organised by county because the data is, and the links between them carry the rest of the picture.
Two numbers organise Caldwell County's heating and cooling year: 1,718 and 2,996, the heating and cooling degree days in the normals at AUSTIN BERGSTROM AP, TX US. Whichever runs larger decides the county's dominant pressure — here, a cooling one — and with it the season a household should prepare for first. The supporting figures fill in the texture: 68.4 degrees as the year's average temperature, 123.5 hot days, 33.0 freezing nights, 35.57 inches of precipitation. Every paragraph on this page is, in the end, a reading of those six numbers on this county's ground.
Because the record names no separate places in Caldwell County, this page reads the county the way its technicians meet it: by ground. 545 square miles of Texas, a centroid south of the Austin metro's centre, weather read from AUSTIN BERGSTROM AP, TX US, and housing spread through the county rather than concentrated in listed communities. The systems in that housing face the same degree days as the rest of the Austin metro; what the county changes is the spacing between them, and spacing is a real part of how service works here.
Look at the second era as well as the first and Caldwell County's stock comes into focus. After the dominant band — homes built since 2000, 51.0% of the metro's total — the next share was built between 1980 and 1999, at 28.8%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.
There is a reason the coverage on this page is described county-first. Heating and cooling demand is generated house by house, and houses sit in counties: in Caldwell County's case, across 545 square miles that hold 0 listed communities and 7 ZIP codes, south of the Austin metro's centre. The metro frame matters — the station, the housing eras, the problem ranking all come from it — but the county is where the frame touches the ground, and the ground is where the systems are.
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 Caldwell County and the Austin metro.
