Butte County heating and cooling, county by county: 1,637 square miles of California lying close to the centre of the Chico metro, 20 ZIP codes, and a climate record read from OROVILLE MUNI AP, CA US. TempReach USA connects you with an independent local HVAC technician; this page sets out the county's own figures.

Butte County covers 1,637 square miles in California. Its climate is read from the normals recorded at OROVILLE MUNI AP, CA US — 2,394 heating degree days against 1,747 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.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at OROVILLE MUNI AP, CA US, the station for the Chico metro this county belongs to. An average year there brings 2,394 heating degree days, 1,747 cooling degree days, 25.67 inches of precipitation, 92.6 days at 90 degrees or above and 11.0 nights at or below freezing, around an average temperature of 63.2 degrees.
Count the cold from the ground up in Butte County and the figures arrange themselves: 2,394 heating degree days against 1,747 cooling degree days, 11.0 freezing nights in an average year, and a housing stock spread over 1,637 square miles whose heating plant was fitted in the decades its communities were built. The diary that follows is written street by street — ignition and exchanger work where the stock is oldest, control and sensor work where it is newest — and the county's technicians read the address before they read the fault.
Distance is the county fact the climate table leaves out. Butte County's centroid lies close to the centre of the Chico metro, roughly 0 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 20 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
There is a scale fact hidden in Butte County's ZIP codes: 20 codes across 1,637 square miles works out to 81.8 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 close to the centre of the Chico metro — 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.
A county with no neighbours on its record is a simpler map: Butte County, 1,637 square miles of California, sitting close to the centre of the Chico metro and carrying the Chico metro's coverage at its edge. Nothing about the work simplifies with the map — the county's housing still spans its building decades, its systems still answer the full degree-day record — but the page can keep its whole attention on one county's ground, which is what it does.
A year in Butte County, counted the way a technician counts it, is not twelve months but two workloads and the weeks between them. The first workload is written as 1,747 cooling degree days, the second as 2,394 heating degree days; 25.67 inches of precipitation fall across both, and the average temperature of 63.2 degrees is simply the figure the two workloads leave behind when they are averaged. The county's heating pressure is whichever workload the count puts first — and the maintenance year is arranged around that ordering.
Start the county at its named places: Chico, Oroville, Magalia, Gridley head a list of 14 communities recorded in Butte 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.
The housing behind Butte County's systems is the Chico metro's housing, read at county scale. The largest single share of the metro's homes was built between 1980 and 1999 — 29.7% of the stock — with 49.4% of homes predating 1980 and 20.9% arriving since 2000, around a median build year of 1980. 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.
A reader who only had Butte County's identifying figures would already know its shape: a county of 1,637 square miles in California, 20 ZIP codes, 14 communities on the record, sitting close to the centre of the Chico metro. 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 Butte County and the Chico metro.
