The short version of this page: Waller County runs to 513 square miles, its weather is the record kept at HOUSTON INTERCONT AP, TX US — 1,266 heating degree days, 3,288 cooling degree days — and its systems live under a humid pressure. One call to TempReach USA, a referral service rather than an HVAC company, 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 513 square miles, with the county's centroid northwest of the Houston metro's centre and roughly 37 miles from the centre it is measured against, that record is Waller County's working climate.
Read Waller County's humidity through its calendar and a pattern emerges: the wettest weeks and the hottest weeks are neighbours, so the condensate drain, the coil and the blower are all examined by peak load at the same time, across every community in the county at once. That overlap is the humid profile's real pressure — not heat alone, not moisture alone, but both arriving together over 513 square miles, 111.3 hot days a year, with no dry season long enough for a neglected system to hide in.
The county's neighbours frame it as well: Liberty County, Montgomery County, San Jacinto County are among the 9 counties on its neighbour list, and together they form the working ground around Waller County's own 513 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 Waller County is a small climate-and-housing district of its own. The county's 5 codes — 77423, 77445, 77446, 77466 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.
Neighbouring counties are the honest context for Waller County's figures. Its 513 square miles sit inside a wider spread of county ground — Liberty County, Montgomery County, San Jacinto County are among the 9 neighbours on its record — and its position northwest of the Houston 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.
Consider what one year asks of a system in Waller County: a cooling season measured at 3,288 degree days, a heating season at 1,266, 111.3 days of serious heat and 10.1 freezing nights, and 51.84 inches of precipitation working on every outdoor unit through all of it. No single figure is remarkable; the combination is the county's climate, and it is the combination a system has to survive for fifteen or twenty years. The service patterns described on this page are that arithmetic, playing out across 513 square miles of housing.
Waller County is recorded by land and code rather than by named places: 513 square miles in Texas, lying northwest of the Houston metro's centre, roughly 37 miles from the metro's centre as the map measures it. Its households sit inside the Houston metro's coverage and share its climate record, but their heating and cooling diary is written at address level — a system in a house on a county road, ageing on its own house's schedule. A county page built from a place list would have little to say here; a page built from the ground itself has the county as it is.
The housing behind Waller County's systems is the Houston metro's housing, read at county scale. The largest single share of the metro's homes was built since 2000 — 40.0% of the stock — with 32.6% of homes predating 1980 and 40.0% arriving since 2000, around a median build year of 1992. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to since 2000 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.
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 Waller County's case, across 513 square miles that hold 0 listed communities and 5 ZIP codes, northwest of the Houston 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 Waller County and the Houston metro.
