Blount County covers 645 square miles in Alabama. Its climate is read from the normals recorded at BIRMINGHAM AP, AL US — 2,533 heating degree days against 2,177 cooling degree days — and its dominant pressure is a heating 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 BIRMINGHAM AP, AL US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 65.0 days at 90 degrees or above, 47.0 nights at or below freezing, 56.62 inches of precipitation and degree-day totals of 2,533 heating against 2,177 cooling. Spread over 645 square miles, with the county's centroid northeast of the Birmingham metro's centre and roughly 38 miles from the centre it is measured against, that record is Blount County's working climate.
There is a second heating pressure in Blount County that the degree days only imply: repetition across distance. A cold snap does not visit one street here; it visits all 8 of the county's ZIP codes in the same night, from the communities nearest the metro's centre to the edge of its 645 square miles, and every ageing system in that ground is examined by the same low temperature at the same hour. That simultaneity — many systems, one weather, a county's worth of roads between the calls — is what makes the cold weeks in a heating-profile county feel different from the same weeks in a city.
Set the county inside its metro and the picture completes. Blount County answers to the Birmingham metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 0 communities, 8 ZIP codes, one county's worth of systems ageing under the record kept at BIRMINGHAM AP, AL US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
There is a scale fact hidden in Blount County's ZIP codes: 8 codes across 645 square miles works out to 80.6 square miles per code, which makes a service call here a matter of ground as well as of systems. The codes on the metro-facing side of the county — the county sits northeast of the Birmingham metro's centre — and the codes at its far edge hold different ground, but both ends ask the same climate questions of their heating and cooling, at different distances.
The counties around Blount County include Shelby County, St. Clair County, Walker County, and the whole group shares the Birmingham metro's climate record from BIRMINGHAM AP, AL US. What the neighbours do not share is this county's ground: 645 square miles, 8 ZIP codes, a centroid northeast of the Birmingham metro's centre. Service patterns cross the county line freely — a cold week fills diaries on both sides of it — but the mix of housing and systems on each side is its own, which is why each county in the group carries its own page.
Extremes, not averages, fill Blount County's emergency diary, and the record names them precisely: 65.0 days a year at 90 degrees or above, 47.0 nights at or below freezing. Between those figures sits the ordinary year — an average of 63.9 degrees, 56.62 inches of rain — in which systems mostly age quietly. The two ends are when ageing becomes failure, which is why the county's dominant heating pressure, the taller of its two peaks, sets the rhythm of its maintenance year as well.
Because the record names no separate places in Blount County, this page reads the county the way its technicians meet it: by ground. 645 square miles of Alabama, a centroid northeast of the Birmingham metro's centre, weather read from BIRMINGHAM AP, AL US, and housing spread through the county rather than concentrated in listed communities. The systems in that housing face the same degree days as the rest of the Birmingham metro; what the county changes is the spacing between them, and spacing is a real part of how service works here.
Ownership writes part of the diary too. Across the Birmingham metro, 70.6% 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. Blount County shares that metro pattern across its 8 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.
One way to hold Blount County in mind is as the local layer of a wider dataset. Above it sits the Birmingham metro, with its Census housing profile and its NOAA station at BIRMINGHAM AP, AL US. At this level sit the county's own numbers — 645 square miles, 6 neighbouring counties, 8 ZIP codes, 0 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 Blount County and the Birmingham metro.
