Brown County covers 530 square miles in Wisconsin. Its climate is read from the normals recorded at GREEN BAY, WI US — 7,505 heating degree days against 508 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.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at GREEN BAY, WI US, the primary metro's station, read here for Brown County. The record's shape is 7,505 heating degree days set against 508 cooling degree days, 31.61 inches of precipitation in an average year, 5.5 days reaching 90 degrees or above and 152.3 nights at or below freezing, with an average temperature of 45.7 degrees across the year.
Divide Brown County's cold by its coverage and the heating diary sharpens: 14 ZIP codes over 530 square miles, 37.9 square miles per code on average, the codes running from 54115 to 54313. 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, 7,505 heating degree days of it, is shared; the ground it is answered on is not.
The county's neighbours frame it as well: Kewaunee County, Oconto County are among the 2 counties on its neighbour list, and together they form the working ground around Brown County's own 530 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.
There is a scale fact hidden in Brown County's ZIP codes: 14 codes across 530 square miles works out to 37.9 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 south of the Green Bay 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 Brown County include Kewaunee County, Oconto County, and the whole group shares the Green Bay metro's climate record from GREEN BAY, WI US. What the neighbours do not share is this county's ground: 530 square miles, 14 ZIP codes, a centroid south of the Green Bay 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.
The county's year divides by load. At one end, 5.5 days at 90 degrees or above pull the cooling season into its long peak; at the other, 152.3 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 45.7 degrees at GREEN BAY, WI US is what those two ends average out to, and 31.61 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Brown 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.
Brown County is a county of distinct communities rather than one continuous town: Green Bay, De Pere, Howard and Ashwaubenon are among the 9 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 south of the Green Bay metro's centre, so its communities meet the Green Bay 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 Green Bay metro's median home was built in 1980, and 50.3% of its homes predate 1980 — in Brown 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, 22.9% 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.
Put the county's coverage facts in one place and they read like this: 530 square miles of land in Wisconsin, 9 listed communities, 14 ZIP codes, 2 neighbouring counties on the record, and a place inside the Green Bay metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
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 Brown County and the Green Bay metro.
