Guadalupe County in one paragraph: 711 square miles in Texas, 7 ZIP codes, a cooling climate pressure read from the normals at SAN ANTONIO INTL AP, TX US, and housing that answers 1,438 heating degree days against 3,148 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.
The station for this county's metro is SAN ANTONIO INTL AP, TX US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 32.38 inches a year; the temperature record averages 69.6 degrees, built from 122.4 days at 90 or above and 14.0 nights at or below freezing; the workload totals 1,438 heating degree days and 3,148 cooling degree days. Guadalupe County is read through that record throughout this page.
Guadalupe County is cooling country by the numbers: 3,148 cooling degree days a year, 122.4 days of serious heat, and homes spread over 711 square miles all asking their systems the same question at the same hour of the same July afternoon. The heating half of the equipment matters — 1,438 heating degree days is not nothing — but it is the cooling load that decides which systems fail, and when. Local technicians read the county that way: spring tune-ups, honest conversations about ageing condensers, and vans stocked for the hot weeks.
Distance is the county fact the climate table leaves out. Guadalupe County's centroid lies east of the San Antonio metro's centre, roughly 37 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 7 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.
7 ZIP codes reach into Guadalupe County's 711 square miles, among them 78108, 78123, 78124, 78130 — an average of 101.6 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.
There are 7 counties on Guadalupe County's neighbour list, Comal County, Kendall County, Medina County among them, and the list is a reminder that a county page is a slice of a continuous map. The slice is worth keeping separate: this county's land area, its ZIP codes and its communities are its own, and its heating and cooling pressure — the cooling profile described above — lands on its own housing. But the slice only makes full sense beside its neighbours, whose pages are linked from this one for exactly that reason.
Two numbers organise Guadalupe County's heating and cooling year: 1,438 and 3,148, the heating and cooling degree days in the normals at SAN ANTONIO INTL 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: 69.6 degrees as the year's average temperature, 122.4 hot days, 14.0 freezing nights, 32.38 inches of precipitation. Every paragraph on this page is, in the end, a reading of those six numbers on this county's ground.
Name the ground and the work follows: in Guadalupe County, the 3 listed communities — New Braunfels, Cibolo, Seguin among them — hold the county's homes, and the homes hold its heating and cooling systems. The largest places supply the steadiest run of calls; the smaller communities supply the long drives and the systems fitted when those places were built. Either way, the county's 711 square miles are not read as one housing stock on this page, because on the ground they are not one: they are these communities, in this order, with these names.
Ownership writes part of the diary too. Across the San Antonio metro, 63.5% of households own their homes, and owner-occupiers and landlords keep different maintenance calendars — owners tending to plan replacements in the shoulder seasons, rented homes more often meeting their systems at the point of failure. Guadalupe County shares that metro pattern across its 7 ZIP codes and its listed communities, and it shows in the timing of the calls as much as in their content: planned work where the owners live, urgent work where they do not.
A reader who only had Guadalupe County's identifying figures would already know its shape: a county of 711 square miles in Texas, 7 ZIP codes, 3 communities on the record, sitting east of the San Antonio 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 Guadalupe County and the San Antonio metro.
