Sequoyah County heating and cooling, county by county: 674 square miles of Oklahoma lying west of the Fort Smith metro's centre, 8 ZIP codes, and a climate record read from FT SMITH RGNL AP, AR US. TempReach USA connects you with an independent local HVAC technician; this page sets out the county's own figures.

The short version of this page: Sequoyah County runs to 674 square miles, its weather is the record kept at FT SMITH RGNL AP, AR US — 3,098 heating degree days, 2,177 cooling degree days — and its systems live under a heating 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 FT SMITH RGNL AP, AR US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 77.7 days at 90 degrees or above, 62.6 nights at or below freezing, 47.34 inches of precipitation and degree-day totals of 3,098 heating against 2,177 cooling. Spread over 674 square miles, with the county's centroid west of the Fort Smith metro's centre and roughly 19 miles from the centre it is measured against, that record is Sequoyah County's working climate.
Read the climate record and the county's pressure names itself. Heating degree days outnumber cooling degree days at FT SMITH RGNL AP, AR US, and the lived version of that statistic is a housing stock whose furnaces and heat pumps run the long season while its cooling takes the short one. Across Sequoyah County's 674 square miles — from Sallisaw to the county's edge communities — the pattern repeats: systems sized for the cold, maintained for the cold, and replaced, when their time comes, with the cold in mind first.
One more county fact belongs in the record: position. Sequoyah County sits at 35.502435, -94.750757 on the map — the centroid of a county whose communities spread across 674 square miles of Oklahoma. 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.
Count the coverage from the codes upward: 74435, 74936 and 74945 are the first codes on Sequoyah County's list of 8, spread across its 674 square miles in Oklahoma. No two of those codes hold quite the same housing — one may be a settled community's streets, the next newer subdivisions, the next open county ground — so the same climate record produces a different run of calls inside each. The full list is printed on this page; the diary is written code by code.
Sequoyah County sits alongside Crawford County, Sebastian County in the Fort Smith area — 2 neighbouring counties share its coverage map in all, and the borders between them are lines on a map rather than changes in the weather. The same station record travels across those borders, the same housing decades appear on both sides, and a technician's ground here is really the cluster: this county and its neighbours, read together, with this page keeping Sequoyah County's own share of the picture separate.
The county's year divides by load. At one end, 77.7 days at 90 degrees or above pull the cooling season into its long peak; at the other, 62.6 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 62.4 degrees at FT SMITH RGNL AP, AR US is what those two ends average out to, and 47.34 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Sequoyah 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.
Sequoyah County is a county of distinct communities rather than one continuous town: Sallisaw, Roland, Muldrow and Vian are among the 4 places on its record, each with its own building era and its own stock of systems. Position plays its part as well — the county sits west of the Fort Smith metro's centre, so its communities meet the Fort Smith metro's weather at slightly different distances from the centre — but it is the place list that a service diary follows, name by name, through the year.
Age is the county's second climate. The Fort Smith metro's median home was built in 1983, and 45.0% of its homes predate 1980 — in Sequoyah County, that share is the older districts and the long-settled communities, where ductwork from an earlier equipment era still serves replacement systems. The newer share, 24.1% built since 2000, concentrates in the county's growth edges. The service diary divides along that line: deep equipment-and-duct conversations at the old end, first-replacement and control conversations at the new one.
The county is worth a page of its own because its facts do not reduce to its metro's. The Fort Smith metro supplies the climate station and the housing profile, but Sequoyah County supplies everything at ground level: 674 square miles, its own communities and codes, its own neighbours — Crawford County, Sebastian County among the 2 on its list — and its own position, west of the Fort Smith metro's centre. The metro page and this page link to each other because neither half of that picture stands well without the other.
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 Sequoyah County and the Fort Smith metro.
