Austin County covers 646 square miles in Texas. Its climate is read from the normals recorded at HOUSTON INTERCONT AP, TX US — 1,266 heating degree days against 3,288 cooling degree days — and its dominant pressure is a humid 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 HOUSTON INTERCONT AP, TX US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 111.3 days at 90 degrees or above, 10.1 nights at or below freezing, 51.84 inches of precipitation and degree-day totals of 1,266 heating against 3,288 cooling. Spread over 646 square miles, with the county's centroid west of the Houston metro's centre and roughly 53 miles from the centre it is measured against, that record is Austin County's working climate.
Humidity in Austin County also divides by code. The county's 7 ZIP codes — 77418, 77473, 77474, 77485 at the head of the list — spread 646 square miles of housing under the same wet record: 51.84 inches of precipitation a year and 3,288 cooling degree days of load, read at HOUSTON INTERCONT AP, TX US. Drains, coils and blowers meet that record in every code, but the housing they serve was fitted decade by decade, so the moisture diary is written code by code rather than county-wide at once.
Set the county inside its metro and the picture completes. Austin County answers to the Houston 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 HOUSTON INTERCONT AP, TX US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
A ZIP code in Austin County is a small climate-and-housing district of its own. The county's 7 codes — 77418, 77473, 77474, 77485 among them — all read the same normals from HOUSTON INTERCONT 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: Austin County lies west of the Houston metro's centre, roughly 53 miles from the metro's centre as the map measures it, with Harris County, Liberty County, Montgomery 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.
Two numbers organise Austin County's heating and cooling year: 1,266 and 3,288, the heating and cooling degree days in the normals at HOUSTON INTERCONT AP, TX US. Whichever runs larger decides the county's dominant pressure — here, a humid one — and with it the season a household should prepare for first. The supporting figures fill in the texture: 70.5 degrees as the year's average temperature, 111.3 hot days, 10.1 freezing nights, 51.84 inches of precipitation. Every paragraph on this page is, in the end, a reading of those six numbers on this county's ground.
Hold Austin County up against its own neighbours and the missing place list stops looking like a gap. Harris County, Liberty County, Montgomery County are among the 9 counties around it; some of them are lists of named towns, this one is 646 square miles of ground lying west of the Houston metro's centre, roughly 53 miles out. Its communities exist — people live in them, heat them, cool them — but the record reaches them through the county's ZIP codes rather than through names, and this page follows the record's way of seeing.
Ownership writes part of the diary too. Across the Houston metro, 61.2% 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. Austin 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 Austin County's identifying figures would already know its shape: a county of 646 square miles in Texas, 7 ZIP codes, 0 communities on the record, sitting west of the Houston 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 Austin County and the Houston metro.
