One county, read on its own ground: Champaign County, Illinois — 10 communities, 29 ZIP codes, 2 neighbouring counties, inside the Champaign metro. TempReach USA connects you with an independent local HVAC technician serving the county, and this page is the homework behind the connection.

The short version of this page: Champaign County runs to 996 square miles, its weather is the record kept at RANTOUL, IL US — 5,719 heating degree days, 1,145 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.
Before the narrative, the numbers themselves, because everything after them is commentary: at RANTOUL, IL US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 33.5 days at 90 degrees or above, 130.5 nights at or below freezing, 40.35 inches of precipitation and degree-day totals of 5,719 heating against 1,145 cooling. Spread over 996 square miles, with the county's centroid close to the centre of the Champaign metro and roughly 11 miles from the centre it is measured against, that record is Champaign County's working climate.
Heating writes this county's HVAC calendar. With 5,719 heating degree days against 1,145 cooling degree days in the normals recorded at RANTOUL, IL US, the systems across Champaign County earn their keep in the cold half of the year: furnaces and heat pumps cycling through 130.5 nights at or below freezing, when a breakdown stops being a comfort problem and becomes a household one. The pressure shows up as midwinter failures on the oldest equipment first, and a maintenance calendar that has to be kept in autumn — because by the time the cold arrives, the county's systems are already on stage.
One more county fact belongs in the record: position. Champaign County sits at 40.138985, -88.196975 on the map — the centroid of a county whose communities spread across 996 square miles of Illinois. 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.
29 ZIP codes reach into Champaign County's 996 square miles, among them 60949, 61801, 61802, 61815 — an average of 34.3 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.
There are 2 counties on Champaign County's neighbour list, Ford County, Piatt County among them, and the list is a reminder that a county page is a slice of a continuous map. The slice is worth keeping separate: this county's land area, its ZIP codes and its communities are its own, and its heating and cooling pressure — the heating profile described above — lands on its own housing. But the slice only makes full sense beside its neighbours, whose pages are linked from this one for exactly that reason.
Two numbers organise Champaign County's heating and cooling year: 5,719 and 1,145, the heating and cooling degree days in the normals at RANTOUL, IL US. Whichever runs larger decides the county's dominant pressure — here, a heating one — and with it the season a household should prepare for first. The supporting figures fill in the texture: 52.3 degrees as the year's average temperature, 33.5 hot days, 130.5 freezing nights, 40.35 inches of precipitation. Every paragraph on this page is, in the end, a reading of those six numbers on this county's ground.
Name the ground and the work follows: in Champaign County, the 10 listed communities — Champaign, Urbana, Rantoul, Mahomet 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 996 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.
Look at the second era as well as the first and Champaign County's stock comes into focus. After the dominant band — homes built before 1960, 26.2% of the metro's total — the next share was built since 2000, at 25.9%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.
One way to hold Champaign County in mind is as the local layer of a wider dataset. Above it sits the Champaign metro, with its Census housing profile and its NOAA station at RANTOUL, IL US. At this level sit the county's own numbers — 996 square miles, 2 neighbouring counties, 29 ZIP codes, 10 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 Champaign County and the Champaign metro.
