Monroe County covers 395 square miles in Indiana. Its climate is read from the normals recorded at BLOOMINGTON MONROE CO AP, IN US — 5,083 heating degree days against 1,026 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.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at BLOOMINGTON MONROE CO AP, IN US, the station for the Bloomington metro this county belongs to. An average year there brings 5,083 heating degree days, 1,026 cooling degree days, 46.92 inches of precipitation, 20.2 days at 90 degrees or above and 108.3 nights at or below freezing, around an average temperature of 53.8 degrees.
The heating season also has an address pattern in Monroe County. Its 11 ZIP codes divide 395 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 — east of the Bloomington metro's centre, roughly 10 miles from the metro's centre — shapes which parts of the county feel the Bloomington 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 ground shapes the work in one more way: 395 square miles is a lot of roofs for a service map to hold, and Monroe County's homes divide between its listed communities — Bloomington, Ellettsville, Smithville-Sanders, Stanford, Stinesville, Harrodsburg — and the roads between them. A technician routed here is working a county, not a street: the drive between calls is part of the diary, and the systems at each end of it were fitted in the decades those communities were built.
A ZIP code in Monroe County is a small climate-and-housing district of its own. The county's 11 codes — 47401, 47403, 47404, 47405 among them — all read the same normals from BLOOMINGTON MONROE CO AP, IN US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.
The counties around Monroe County include Owen County, and the whole group shares the Bloomington metro's climate record from BLOOMINGTON MONROE CO AP, IN US. What the neighbours do not share is this county's ground: 395 square miles, 11 ZIP codes, a centroid east of the Bloomington 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 service calendar for Monroe County can be written straight from its station record. Spring belongs to the cooling plant: 1,026 cooling degree days are coming, and the systems that will carry them are checked before the first of the 20.2 hot days arrives. Autumn belongs to the heating plant, ahead of 5,083 heating degree days and 108.3 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at BLOOMINGTON MONROE CO AP, IN US does not change much year to year, which is what makes the calendar worth keeping.
Monroe County is a county of distinct communities rather than one continuous town: Bloomington, Ellettsville, Smithville-Sanders and Stanford are among the 6 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 east of the Bloomington metro's centre, so its communities meet the Bloomington 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.
The growth figures deserve their own reading in Monroe County. 24.9% of the Bloomington 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 43.9% 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.
Coverage, for Monroe County, is a set of overlapping maps. The land map is 395 square miles. The address map is 11 ZIP codes and 6 listed communities. The service map is the Bloomington metro, whose coverage the county sits inside — east of the Bloomington metro's centre, roughly 10 miles from its centre. The weather map is one station's record, kept at BLOOMINGTON MONROE CO AP, IN US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.
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.
