Harris County heating & cooling, in brief
In brief: 1,707 square miles of Texas, a climate read from HOUSTON INTERCONT AP, TX US's normals, and a humid pressure as the county's dominant one — 1,266 heating degree days set against 3,288 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 Harris County.
The Harris County climate record
Read Harris County's weather the way this page reads it: through the thirty-year normals kept at HOUSTON INTERCONT AP, TX US for the Houston metro. Those normals give the county 3,288 cooling degree days and 1,266 heating degree days a year, 51.84 inches of precipitation, 111.3 days at 90 degrees or above, 10.1 nights at or below freezing, and an average temperature of 70.5 degrees — the fixed background every system in the county works against.
Read Harris 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 1,707 square miles, 111.3 hot days a year, with no dry season long enough for a neglected system to hide in.
One more county fact belongs in the record: position. Harris County sits at 29.857273, -95.393037 on the map — the centroid of a county whose communities spread across 1,707 square miles of Texas. Position decides which end of the metro's weather arrives first and which of its service patterns a household here meets most; the rest of this page is that position, read through the climate record and the metro's data.
132 ZIP codes reach into Harris County's 1,707 square miles, among them 77002, 77003, 77004, 77005 — an average of 12.9 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.
Read the map around Harris County and a working region appears: Galveston County, Liberty County, Montgomery County, San Jacinto County are the neighbouring names at the head of its list of 9, 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.
Extremes, not averages, fill Harris County's emergency diary, and the record names them precisely: 111.3 days a year at 90 degrees or above, 10.1 nights at or below freezing. Between those figures sits the ordinary year — an average of 70.5 degrees, 51.84 inches of rain — in which systems mostly age quietly. The two ends are when ageing becomes failure, which is why the county's dominant humid pressure, the taller of its two peaks, sets the rhythm of its maintenance year as well.
Communities and housing in Harris County
The county's place list tells its own story. Houston (2,300,419 residents) is the largest of the 6 communities the record names for Harris County, with Pasadena (149,345 residents) behind it and Atascocita and Baytown further down the list. A technician working this county works all of those places in a single week, and the systems change character with the address: the era a community was built in decides whether the call is about an ageing furnace, a condenser at the end of its summers, or ductwork that predates the equipment it now serves.
The county's position frames its housing as well. Harris County lies close to the centre of the Houston metro, roughly 1 miles out, and the metro's era mix — 40.0% built since 2000, 27.4% 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 Harris 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 Harris County in mind is as the local layer of a wider dataset. Above it sits the Houston metro, with its Census housing profile and its NOAA station at HOUSTON INTERCONT AP, TX US. At this level sit the county's own numbers — 1,707 square miles, 9 neighbouring counties, 132 ZIP codes, 6 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.

Why does humidity burden on homes and cooling systems lead the problem list connected to Harris County, Texas?
The leader is humidity burden on homes and cooling systems, and the county's own numbers explain its lead. A humid-profile county lying close to the centre of the Houston metro asks its equipment for one workload above the others, recorded at HOUSTON INTERCONT AP, TX US as 111.3 hot days and 10.1 freezing nights in an average year. The metro page carries the full ranking; this page carries the reason the ranking bends toward that workload here. On the county's own record, the ground is entered as 1707.288 square miles — about 1,092,664 acres — centred at 29.857273, -95.393037, close to the centre of the Houston metro.

The county's own map reads: Houston 2,300,419; Pasadena 149,345; Atascocita 93,926; Baytown 84,538; Spring 67,103; Channelview 43,536 — name and population, place by place.
Before which peak should a Harris County, Texas household book its HVAC maintenance?
Two peaks, one taller. Every county in this climate gets a hot-season rush and a cold-season rush; in Harris County, Texas the figures at HOUSTON INTERCONT AP, TX US — 1,266 heating degree days against 3,288 cooling degree days — say the humid side runs the longer season. The households in Houston and across the county who schedule their checks in the shoulder weeks meet their systems on their own timetable instead of the weather's. The county's own ZIP list includes this run: 77070, 77071, 77072, 77073, 77074, 77075, 77076, 77077, 77078, 77079.

How does this Harris County, Texas page relate to the Houston city page?
Both, for different halves of the picture. The Houston city page, linked above, carries the metro-wide homework: the housing-era profile, the problem ranking, the services in depth. This county page narrows the same records to Harris County, Texas's own ground — 1,707 square miles, its communities from Houston outward, its ZIP codes, and the climate pressure described in its narrative. The links run in both directions on purpose: the city page's Counties We Cover section points here, and this page points back. A run from the county's code ledger, as recorded: 77070, 77071, 77072, 77073, 77074, 77075, 77076, 77077, 77078, 77079.

Entered by ground: 1707.288 square miles of Texas, about 1,092,664 acres, centred at 29.857273, -95.393037, roughly 1 miles from the metro centre it is measured against.
Our role in Harris County, stated plainly
