In brief: 861 square miles of Minnesota, a climate read from DULUTH, MN US's normals, and a heating pressure as the county's dominant one — 9,115 heating degree days set against 255 cooling degree days in an average year. TempReach USA does not do the work itself; it is a referral service, and one call connects you with an independent local HVAC technician serving Carlton County.
One record, one county: the normals at DULUTH, MN US — 9,115 heating degree days, 255 cooling degree days, 31.18 inches of precipitation, an average temperature of 40.6 degrees — applied to Carlton County's own 861 square miles and its 11 ZIP codes. The figures are the Duluth metro's; the ground they are applied to, lying southwest of the Duluth metro's centre, is this county's alone, and this section reads the two together.
Divide Carlton 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 55707 to 55798. 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, 9,115 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. Carlton County answers to the Duluth 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 DULUTH, MN US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
Routing in Carlton County is written in five digits. The county's codes begin at 55707 and run to 55798, 11 in total, and between the first and the last sits the county's full spread of ground — 861 square miles from the metro-facing edge to the far side. A technician's week here is a tour of those codes, and the tour is also a tour of the county's building history, because each code's systems were largely fitted when that code's streets were built.
The counties around Carlton County include Douglas County, St. Louis County, and the whole group shares the Duluth metro's climate record from DULUTH, MN US. What the neighbours do not share is this county's ground: 861 square miles, 11 ZIP codes, a centroid southwest of the Duluth 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.
A year in Carlton 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 255 cooling degree days, the second as 9,115 heating degree days; 31.18 inches of precipitation fall across both, and the average temperature of 40.6 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.
Name the ground and the work follows: in Carlton County, the 3 listed communities — Cloquet, Moose Lake, Esko among them — hold the county's homes, and the homes hold its heating and cooling systems. The largest places supply the steadiest run of calls; the smaller communities supply the long drives and the systems fitted when those places were built. Either way, the county's 861 square miles are not read as one housing stock on this page, because on the ground they are not one: they are these communities, in this order, with these names.
Census figures give Carlton County's heating and cooling its proportions. The metro it belongs to counts 142,751 housing units across 119,183 households, 72.9% of them owner-occupied, and the era mix runs 45.6% before 1960, 23.0% from 1960 to 1979, 16.0% from 1980 to 1999 and 15.4% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Carlton County street, built forty years apart, can need entirely different conversations from the same technician.
One way to hold Carlton County in mind is as the local layer of a wider dataset. Above it sits the Duluth metro, with its Census housing profile and its NOAA station at DULUTH, MN US. At this level sit the county's own numbers — 861 square miles, 2 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.
One call connects you with an independent local heating and cooling professional serving Carlton County and the Duluth metro.
