Start here if you read nothing else: this page covers Greene County, Ohio — 414 square miles, 3 listed communities, a centroid southeast of the Dayton metro's centre. Its climate record, from DAYTON INTL AP, OH US, sets a heating pressure on its systems. TempReach USA publishes the homework and routes the call; an independent local HVAC technician serving the county does the work.
Before the narrative, the numbers themselves, because everything after them is commentary: at DAYTON INTL AP, OH US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 15.5 days at 90 degrees or above, 109.9 nights at or below freezing, 41.33 inches of precipitation and degree-day totals of 5,149 heating against 1,154 cooling. Spread over 414 square miles, with the county's centroid southeast of the Dayton metro's centre and roughly 16 miles from the centre it is measured against, that record is Greene County's working climate.
There is a second heating pressure in Greene County that the degree days only imply: repetition across distance. A cold snap does not visit one street here; it visits all 17 of the county's ZIP codes in the same night, from the communities nearest the metro's centre to the edge of its 414 square miles, and every ageing system in that ground is examined by the same low temperature at the same hour. That simultaneity — many systems, one weather, a county's worth of roads between the calls — is what makes the cold weeks in a heating-profile county feel different from the same weeks in a city.
The county's neighbours frame it as well: Miami County, Montgomery County are among the 2 counties on its neighbour list, and together they form the working ground around Greene County's own 414 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.
Count the coverage from the codes upward: 45301, 45305 and 45307 are the first codes on Greene County's list of 17, spread across its 414 square miles in Ohio. No two of those codes hold quite the same housing — one may be a settled community's streets, the next newer subdivisions, the next open county ground — so the same climate record produces a different run of calls inside each. The full list is printed on this page; the diary is written code by code.
Greene County sits alongside Miami County, Montgomery County in the Dayton area — 2 neighbouring counties share its coverage map in all, and the borders between them are lines on a map rather than changes in the weather. The same station record travels across those borders, the same housing decades appear on both sides, and a technician's ground here is really the cluster: this county and its neighbours, read together, with this page keeping Greene County's own share of the picture separate.
Extremes, not averages, fill Greene County's emergency diary, and the record names them precisely: 15.5 days a year at 90 degrees or above, 109.9 nights at or below freezing. Between those figures sits the ordinary year — an average of 53.9 degrees, 41.33 inches of rain — in which systems mostly age quietly. The two ends are when ageing becomes failure, which is why the county's dominant heating pressure, the taller of its two peaks, sets the rhythm of its maintenance year as well.
There is a practical reason this page names Greene 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 Beavercreek through its remaining communities and beyond, each carry that clue in their streets. The metro data on the Dayton page describes the whole region; this list is where the description becomes local.
Age is the county's second climate. The Dayton metro's median home was built in 1968, and 69.3% of its homes predate 1980 — in Greene County, that share is the older districts and the long-settled communities, where ductwork from an earlier equipment era still serves replacement systems. The newer share, 12.8% built since 2000, concentrates in the county's growth edges. The service diary divides along that line: deep equipment-and-duct conversations at the old end, first-replacement and control conversations at the new one.
There is a reason the coverage on this page is described county-first. Heating and cooling demand is generated house by house, and houses sit in counties: in Greene County's case, across 414 square miles that hold 3 listed communities and 17 ZIP codes, southeast of the Dayton metro's centre. The metro frame matters — the station, the housing eras, the problem ranking all come from it — but the county is where the frame touches the ground, and the ground is where the systems are.
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 Greene County and the Dayton metro.
