The short version of this page: Hendricks County runs to 407 square miles, its weather is the record kept at INDIANAPOLIS EAGLE CREEK AP, IN US — 5,221 heating degree days, 1,127 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.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at INDIANAPOLIS EAGLE CREEK AP, IN US, the station for the Indianapolis metro this county belongs to. An average year there brings 5,221 heating degree days, 1,127 cooling degree days, 40.67 inches of precipitation, 16.6 days at 90 degrees or above and 105.9 nights at or below freezing, around an average temperature of 53.7 degrees.
The heating season also has an address pattern in Hendricks County. Its 12 ZIP codes divide 407 square miles into service ground where the same January night lands on older streets, subdivisions and edge communities at once, and the county's position — west of the Indianapolis metro's centre, roughly 21 miles from the metro's centre — shapes which parts of the county feel the Indianapolis metro's cold at full strength. The systems answer accordingly: one long heating season, read ZIP by ZIP, with the oldest furnaces and heat exchangers carrying the heaviest share of it.
The county's neighbours frame it as well: Madison County, Marion County, Morgan County are among the 10 counties on its neighbour list, and together they form the working ground around Hendricks County's own 407 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.
Routing in Hendricks County is written in five digits. The county's codes begin at 46103 and run to 46234, 12 in total, and between the first and the last sits the county's full spread of ground — 407 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.
There are 10 counties on Hendricks County's neighbour list, Madison County, Marion County, Morgan 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.
The county's year divides by load. At one end, 16.6 days at 90 degrees or above pull the cooling season into its long peak; at the other, 105.9 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 53.7 degrees at INDIANAPOLIS EAGLE CREEK AP, IN US is what those two ends average out to, and 40.67 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Hendricks 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 Hendricks 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 Plainfield through its remaining communities and beyond, each carry that clue in their streets. The metro data on the Indianapolis page describes the whole region; this list is where the description becomes local.
The county's position frames its housing as well. Hendricks County lies west of the Indianapolis metro's centre, roughly 21 miles out, and the metro's era mix — 26.6% built since 2000, 25.9% before 1960, median year 1982 — reads at this distance with a county accent: the shares nearer the centre and the shares at the edge were platted in different decades of the metro's growth. Which band a given Hendricks County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
A reader who only had Hendricks County's identifying figures would already know its shape: a county of 407 square miles in Indiana, 12 ZIP codes, 3 communities on the record, sitting west of the Indianapolis metro's centre. What the figures cannot say alone is how the ground feels to work — the drives between calls, the mix of decades in the housing, the season that runs taller — and that is what the rest of this page is for, section by section.
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 Hendricks County and the Indianapolis metro.
