Montgomery County heating and cooling, county by county: 387 square miles of Virginia lying east of the Blacksburg metro's centre, 7 ZIP codes, and a climate record read from ROANOKE RGNL AP, VA US. TempReach USA connects you with an independent local HVAC technician; this page sets out the county's own figures.

Start here if you read nothing else: this page covers Montgomery County, Virginia — 387 square miles, 6 listed communities, a centroid east of the Blacksburg metro's centre. Its climate record, from ROANOKE RGNL AP, VA 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 ROANOKE RGNL AP, VA US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 30.4 days at 90 degrees or above, 76.6 nights at or below freezing, 42.82 inches of precipitation and degree-day totals of 3,868 heating against 1,368 cooling. Spread over 387 square miles, with the county's centroid east of the Blacksburg metro's centre and roughly 9 miles from the centre it is measured against, that record is Montgomery County's working climate.
There is a second heating pressure in Montgomery County that the degree days only imply: repetition across distance. A cold snap does not visit one street here; it visits all 7 of the county's ZIP codes in the same night, from the communities nearest the metro's centre to the edge of its 387 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 ground shapes the work in one more way: 387 square miles is a lot of roofs for a service map to hold, and Montgomery County's homes divide between its listed communities — Blacksburg, Christiansburg, Merrimac, Shawsville, Elliston, Riner — 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.
The ZIP list is the county's working map. Montgomery County carries 7 codes, running from 24060 through 24087 in the middle of the list to 24162 at its end, and every code on it is a small housing census of its own — the building decades, the system generations, the duct materials of its streets. Heating and cooling work routed by those codes meets the county in slices, and the slices differ more than the county's shared climate record would suggest.
There are 4 counties on Montgomery County's neighbour list, Floyd County, Giles County, Pulaski 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, 30.4 days at 90 degrees or above pull the cooling season into its long peak; at the other, 76.6 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 58.1 degrees at ROANOKE RGNL AP, VA US is what those two ends average out to, and 42.82 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Montgomery 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 Montgomery 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 6 places recorded here, from Blacksburg through Shawsville and beyond, each carry that clue in their streets. The metro data on the Blacksburg page describes the whole region; this list is where the description becomes local.
Spread the metro's eras over Montgomery County's own ground and the housing paragraph becomes a map: 387 square miles, 7 ZIP codes at 55.3 square miles per code, and a stock whose largest band was built between 1980 and 1999 (29.7%), whose pre-1980 share runs to 47.9% and whose post-2000 share runs to 22.3%. The percentages are the metro's; the streets they land on are this county's, and a technician driving from one end of the county to the other drives through the bands in sequence.
One way to hold Montgomery County in mind is as the local layer of a wider dataset. Above it sits the Blacksburg metro, with its Census housing profile and its NOAA station at ROANOKE RGNL AP, VA US. At this level sit the county's own numbers — 387 square miles, 4 neighbouring counties, 7 ZIP codes, 6 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 Montgomery County and the Blacksburg metro.
