Fillmore County in one paragraph: 861 square miles in Minnesota, 11 ZIP codes, a heating climate pressure read from the normals at ROCHESTER INTL AP, MN US, and housing that answers 7,856 heating degree days against 533 cooling degree days a year. TempReach USA is a referral service, not an HVAC company — one call connects you with an independent local HVAC technician serving this county.
Before the narrative, the numbers themselves, because everything after them is commentary: at ROCHESTER INTL AP, MN US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 5.0 days at 90 degrees or above, 155.8 nights at or below freezing, 34.67 inches of precipitation and degree-day totals of 7,856 heating against 533 cooling. Spread over 861 square miles, with the county's centroid southeast of the Rochester metro's centre and roughly 27 miles from the centre it is measured against, that record is Fillmore County's working climate.
Divide Fillmore County's cold by its coverage and the heating diary sharpens: 11 ZIP codes over 861 square miles, 78.3 square miles per code on average, the codes running from 55922 to 55990. A furnace failure in the code nearest the metro reads differently from one at the county's far edge — not in the fault, which is the same worn igniter or tired blower, but in everything around it: the drive, the house's decade, the odds the system has already been replaced once. The cold itself, 7,856 heating degree days of it, is shared; the ground it is answered on is not.
Set the county inside its metro and the picture completes. Fillmore County answers to the Rochester metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 3 communities, 11 ZIP codes, one county's worth of systems ageing under the record kept at ROCHESTER INTL AP, MN US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
11 ZIP codes reach into Fillmore County's 861 square miles, among them 55922, 55923, 55935, 55939 — an average of 78.3 square miles of county ground per code. The codes are more than a mailing grid here: they are how the county's service ground divides in practice, each code holding its own mix of housing eras, its own streets of systems ageing on their own schedules. A call in one code and a call in the next can be the same fault in different decades of house.
Position first: Fillmore County lies southeast of the Rochester metro's centre, roughly 27 miles from the metro's centre as the map measures it, with Dodge County, Olmsted County, Wabasha 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.
The county's year divides by load. At one end, 5.0 days at 90 degrees or above pull the cooling season into its long peak; at the other, 155.8 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 44.8 degrees at ROCHESTER INTL AP, MN US is what those two ends average out to, and 34.67 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Fillmore 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.
There is a practical reason this page names Fillmore County's communities one by one. A heating or cooling system belongs to a house, a house belongs to a community, and the community's building decade is the strongest single clue to what the system will need — the 3 places recorded here, from Chatfield through its remaining communities and beyond, each carry that clue in their streets. The metro data on the Rochester page describes the whole region; this list is where the description becomes local.
Spread the metro's eras over Fillmore County's own ground and the housing paragraph becomes a map: 861 square miles, 11 ZIP codes at 78.3 square miles per code, and a stock whose largest band was built since 2000 (29.9%), whose pre-1980 share runs to 46.2% and whose post-2000 share runs to 29.9%. The percentages are the metro's; the streets they land on are this county's, and a technician driving from one end of the county to the other drives through the bands in sequence.
One way to hold Fillmore County in mind is as the local layer of a wider dataset. Above it sits the Rochester metro, with its Census housing profile and its NOAA station at ROCHESTER INTL AP, MN US. At this level sit the county's own numbers — 861 square miles, 3 neighbouring counties, 11 ZIP codes, 3 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.
