Comal County covers 560 square miles in Texas. Its climate is read from the normals recorded at SAN ANTONIO INTL AP, TX US — 1,438 heating degree days against 3,148 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 SAN ANTONIO INTL AP, TX US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 122.4 days at 90 degrees or above, 14.0 nights at or below freezing, 32.38 inches of precipitation and degree-day totals of 1,438 heating against 3,148 cooling. Spread over 560 square miles, with the county's centroid northeast of the San Antonio metro's centre and roughly 28 miles from the centre it is measured against, that record is Comal County's working climate.
Cooling writes this county's HVAC calendar. With 3,148 cooling degree days against 1,438 heating degree days in the normals recorded at SAN ANTONIO INTL AP, TX US, the systems across Comal County spend their lives working the hot half of the year: condensers cycling through 122.4 days at 90 degrees or more, coils pulling moisture out of the air for month after month. The pressure shows up as midsummer breakdowns, capacities fading on the oldest equipment first, and a maintenance calendar that has to be kept in spring — because by the time the heat arrives, the county's systems are already on stage.
Set the county inside its metro and the picture completes. Comal County answers to the San Antonio metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 1 communities, 6 ZIP codes, one county's worth of systems ageing under the record kept at SAN ANTONIO INTL 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 Comal County is written in five digits. The county's codes begin at 78070 and run to 78623, 6 in total, and between the first and the last sits the county's full spread of ground — 560 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.
Read the map around Comal County and a working region appears: Guadalupe County, Kendall County, Medina County, Wilson County are the neighbouring names at the head of its list of 7, and together these counties form the ground a local technician actually covers. The county line decides which page describes a home; it does not decide the weather the home's system faces, the decade its street was built in, or the season its diary fills. Those are regional — and the region, on this site, is a set of county pages that link to one another, as the cards below do.
There is a geography to Comal County's seasons that the totals flatten. The county lies northeast of the San Antonio metro's centre, roughly 28 miles from the centre the record is measured against, and its 560 square miles do not meet a hot week or a cold snap in one voice: the ground nearer the metro and the ground at the county's far edge live the same 122.4 hot days and 14.0 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Comal County's named places — Canyon Lake — anchor a county that is mostly ground between names: 560 square miles, 6 ZIP codes, and housing that follows the roads more than the towns. The wider metro it belongs to is anchored by San Antonio (1,458,954 residents) and New Braunfels, but this county's own diary is quieter and more spread out: individual systems in individual houses, ageing on the schedule of the decade each house was built, from the named communities outward.
The county's position frames its housing as well. Comal County lies northeast of the San Antonio metro's centre, roughly 28 miles out, and the metro's era mix — 39.8% built since 2000, 26.3% between 1980 and 1999, median year 1992 — reads at this distance with a county accent: the shares nearer the centre and the shares at the edge were platted in different decades of the metro's growth. Which band a given Comal County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
One way to hold Comal County in mind is as the local layer of a wider dataset. Above it sits the San Antonio metro, with its Census housing profile and its NOAA station at SAN ANTONIO INTL AP, TX US. At this level sit the county's own numbers — 560 square miles, 7 neighbouring counties, 6 ZIP codes, 1 listed places — and below it, not published anywhere, sit the individual homes whose systems all of it describes. This page works at the middle level, where the data is still local enough to act on.
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 Comal County and the San Antonio metro.
