In brief: 1,240 square miles of Texas, a climate read from SAN ANTONIO INTL AP, TX US's normals, and a cooling pressure as the county's dominant one — 1,438 heating degree days set against 3,148 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 Bexar County.
One record, one county: the normals at SAN ANTONIO INTL AP, TX US — 1,438 heating degree days, 3,148 cooling degree days, 32.38 inches of precipitation, an average temperature of 69.6 degrees — applied to Bexar County's own 1,240 square miles and its 70 ZIP codes. The figures are the San Antonio metro's; the ground they are applied to, lying close to the centre of the San Antonio metro, is this county's alone, and this section reads the two together.
Station figures only tell half of Bexar County's cooling story; the housing tells the rest. An average temperature of 69.6 degrees and 32.38 inches of rain a year at SAN ANTONIO INTL AP, TX US describe the air the county's systems breathe, while the stock itself — spread across the county's listed communities and the roads between them — decides how hard each system works to change that air indoors. Where the homes are older the load rides on ageing coils; where they are newer it rides on matched fleets installed in the same building seasons. Both diaries peak in the same weeks.
The county's neighbours frame it as well: Atascosa County, Bandera County, Comal County are among the 7 counties on its neighbour list, and together they form the working ground around Bexar County's own 1,240 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 Bexar County is a small climate-and-housing district of its own. The county's 70 codes — 78002, 78023, 78073, 78101 among them — all read the same normals from SAN ANTONIO INTL AP, TX 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: Bexar County lies close to the centre of the San Antonio metro, roughly 4 miles from the metro's centre as the map measures it, with Atascosa County, Bandera County, Comal 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 Bexar County can be written straight from its station record. Spring belongs to the cooling plant: 3,148 cooling degree days are coming, and the systems that will carry them are checked before the first of the 122.4 hot days arrives. Autumn belongs to the heating plant, ahead of 1,438 heating degree days and 14.0 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at SAN ANTONIO INTL AP, TX US does not change much year to year, which is what makes the calendar worth keeping.
Bexar County is a county of distinct communities rather than one continuous town: San Antonio, Schertz, Timberwood Park and Converse are among the 8 places on its record, each with its own building era and its own stock of systems. Position plays its part as well — the county sits close to the centre of the San Antonio metro, so its communities meet the San Antonio metro's weather at slightly different distances from the centre — but it is the place list that a service diary follows, name by name, through the year.
Look at the second era as well as the first and Bexar County's stock comes into focus. After the dominant band — homes built since 2000, 39.8% of the metro's total — the next share was built between 1980 and 1999, at 26.3%. 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.
Put the county's coverage facts in one place and they read like this: 1,240 square miles of land in Texas, 8 listed communities, 70 ZIP codes, 7 neighbouring counties on the record, and a place inside the San Antonio metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
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.
