The short version of this page: Kewaunee County runs to 342 square miles, its weather is the record kept at GREEN BAY, WI US — 7,505 heating degree days, 508 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.
Climate on this page is not a national average wearing a county's name. It is the specific record at GREEN BAY, WI US: 45.7 degrees as the average temperature, 31.61 inches of precipitation, 5.5 hot days and 152.3 freezing nights in the average year, 7,505 heating degree days against 508 cooling degree days. Kewaunee County — 342 square miles, 4 ZIP codes, 3 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
Kewaunee County is heating country by the numbers: 7,505 heating degree days a year, 152.3 freezing nights, and homes spread over 342 square miles all asking their systems the same question on the same January night. The cooling half of the equipment matters — 508 cooling degree days is not nothing — but it is the heating load that decides which systems fail, and when. Local technicians read the county that way: autumn tune-ups, honest conversations about ageing furnaces and heat exchangers, and vans stocked for the cold weeks.
One more county fact belongs in the record: position. Kewaunee County sits at 44.605677, -87.448008 on the map — the centroid of a county whose communities spread across 342 square miles of Wisconsin. 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.
4 ZIP codes reach into Kewaunee County's 342 square miles, among them 54201, 54205, 54216, 54217 — an average of 85.6 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.
Read the map around Kewaunee County and a working region appears: Brown County, Oconto County are the neighbouring names at the head of its list of 2, and together these counties form the ground a local technician actually covers. The county line decides which page describes a home; it does not decide the weather the home's system faces, the decade its street was built in, or the season its diary fills. Those are regional — and the region, on this site, is a set of county pages that link to one another, as the cards below do.
Consider what one year asks of a system in Kewaunee County: a cooling season measured at 508 degree days, a heating season at 7,505, 5.5 days of serious heat and 152.3 freezing nights, and 31.61 inches of precipitation working on every outdoor unit through all of it. No single figure is remarkable; the combination is the county's climate, and it is the combination a system has to survive for fifteen or twenty years. The service patterns described on this page are that arithmetic, playing out across 342 square miles of housing.
The county's place list tells its own story. Algoma (3,219 residents) is the largest of the 3 communities the record names for Kewaunee County, with Kewaunee (2,824 residents) behind it and Luxemburg and its remaining communities further down the list. A technician working this county works all of those places in a single week, and the systems change character with the address: the era a community was built in decides whether the call is about an ageing furnace, a condenser at the end of its summers, or ductwork that predates the equipment it now serves.
The growth figures deserve their own reading in Kewaunee County. 22.9% of the Green Bay metro's homes were built since 2000 — the largest or near-largest band in many of its counties — and those homes are now old enough that their first systems are reaching replacement age together, subdivision by subdivision. Set against them, the 50.3% of the metro's stock that predates 1980 is deep into its second and third systems. One county, two replacement waves running at once, and a maintenance diary that has to serve both.
One way to hold Kewaunee County in mind is as the local layer of a wider dataset. Above it sits the Green Bay metro, with its Census housing profile and its NOAA station at GREEN BAY, WI US. At this level sit the county's own numbers — 342 square miles, 2 neighbouring counties, 4 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.
One call connects you with an independent local heating and cooling professional serving Kewaunee County and the Green Bay metro.
