Start here if you read nothing else: this page covers Richland County, South Carolina — 757 square miles, 6 listed communities, a centroid east of the Columbia metro's centre. Its climate record, from COLUMBIA OWENS DWTN AP, SC US, sets a cooling pressure on its systems. TempReach USA publishes the homework and routes the call; an independent local HVAC technician serving the county does the work.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at COLUMBIA OWENS DWTN AP, SC US, the station for the Columbia metro this county belongs to. An average year there brings 2,210 heating degree days, 2,418 cooling degree days, 43.68 inches of precipitation, 82.7 days at 90 degrees or above and 33.3 nights at or below freezing, around an average temperature of 65.5 degrees.
Cooling pressure in Richland County can also be counted in ground rather than in degrees. The county spreads its homes over 757 square miles — 18 ZIP codes at 42.1 square miles per code, running from 29016 to 29229 — and every one of those codes asks the same July question of systems fitted in different building decades. The degree days, 2,418 of them against 2,210 heating degree days, set the season's size; the codes and the decades set the order in which it is answered.
The county's neighbours frame it as well: Fairfield County, Kershaw County, Lexington County are among the 5 counties on its neighbour list, and together they form the working ground around Richland County's own 757 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 Richland County is a small climate-and-housing district of its own. The county's 18 codes — 29016, 29044, 29052, 29061 among them — all read the same normals from COLUMBIA OWENS DWTN AP, SC 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: Richland County lies east of the Columbia metro's centre, roughly 10 miles from the metro's centre as the map measures it, with Fairfield County, Kershaw County, Lexington 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.
A service calendar for Richland County can be written straight from its station record. Spring belongs to the cooling plant: 2,418 cooling degree days are coming, and the systems that will carry them are checked before the first of the 82.7 hot days arrives. Autumn belongs to the heating plant, ahead of 2,210 heating degree days and 33.3 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at COLUMBIA OWENS DWTN AP, SC US does not change much year to year, which is what makes the calendar worth keeping.
Start the county at its named places: Columbia, St. Andrews, Seven Oaks, Dentsville head a list of 6 communities recorded in Richland County. The list matters to heating and cooling because communities concentrate the housing — a street of homes built in one decade produces one kind of service diary, the next community's different decade produces another — and because the roads between the named places are part of the working day here. The county page's climate record is shared; the ground it lands on is divided among these names.
Look at the second era as well as the first and Richland County's stock comes into focus. After the dominant band — homes built since 2000, 33.6% of the metro's total — the next share was built between 1980 and 1999, at 30.2%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.
A reader who only had Richland County's identifying figures would already know its shape: a county of 757 square miles in South Carolina, 18 ZIP codes, 6 communities on the record, sitting east of the Columbia 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 Richland County and the Columbia metro.
