Jefferson County Heating & Cooling Services

The Jefferson County climate record

Every climate number on this page comes from one record: the NOAA 1991-2020 normals at BIRMINGHAM AP, AL US, the primary metro's station, read here for Jefferson County. The record's shape is 2,533 heating degree days set against 2,177 cooling degree days, 56.62 inches of precipitation in an average year, 65.0 days reaching 90 degrees or above and 47.0 nights at or below freezing, with an average temperature of 63.9 degrees across the year.

The neighbours tell part of Jefferson County's heating story: Blount County, Chilton County, Shelby County are among the counties around it, all reading the same record at BIRMINGHAM AP, AL US, all filling their diaries in the same cold weeks. What separates this county's share is its own ground — 1,112 square miles lying close to the centre of the Birmingham metro, roughly 9 miles from the metro's centre — and its own housing, fitted across the decades its communities were built. The season is regional; the failures are local, one system at a time, at addresses only this county has.

The county's neighbours frame it as well: Blount County, Chilton County, Shelby County are among the 6 counties on its neighbour list, and together they form the working ground around Jefferson County's own 1,112 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 Jefferson County is a small climate-and-housing district of its own. The county's 54 codes — 35005, 35006, 35020, 35022 among them — all read the same normals from BIRMINGHAM AP, AL 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.

Read the map around Jefferson County and a working region appears: Blount County, Chilton County, Shelby County, St. Clair County are the neighbouring names at the head of its list of 6, 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.

The county's year divides by load. At one end, 65.0 days at 90 degrees or above pull the cooling season into its long peak; at the other, 47.0 nights at or below freezing do the same for heating; between them sit the shoulder weeks when neither plant runs hard. An average temperature of 63.9 degrees at BIRMINGHAM AP, AL US is what those two ends average out to, and 56.62 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Jefferson County's households plan around that division — service ahead of the taller peak, filters and checks in the shoulders — whether they name it or not.

Communities and housing in Jefferson County

Communities across Jefferson County include Birmingham, Vestavia Hills, Homewood and Trussville — 9 listed places in all, spread over the county's 1,112 square miles in Alabama. Each community's housing was built in its own decades, so the heating and cooling diary reads differently from one name on that list to the next: older systems and original ductwork in the long-settled places, matched fleets ageing together in the subdivisions, and additions and conversions in the communities still growing at the county's edges.

The housing behind Jefferson County's systems is the Birmingham metro's housing, read at county scale. The largest single share of the metro's homes was built between 1980 and 1999 — 27.5% of the stock — with 45.9% of homes predating 1980 and 26.6% arriving since 2000, around a median build year of 1983. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to between 1980 and 1999 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.

Coverage, for Jefferson County, is a set of overlapping maps. The land map is 1,112 square miles. The address map is 54 ZIP codes and 9 listed communities. The service map is the Birmingham metro, whose coverage the county sits inside — close to the centre of the Birmingham metro, roughly 9 miles from its centre. The weather map is one station's record, kept at BIRMINGHAM AP, AL US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.

Our role in Jefferson County, stated plainly

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.
