The median Roanoke home was built in 1975; 58.5% of the stock predates 1980, and the pattern this metro's own data ranks first is the refrigerant transition reaching older systems. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving your ZIP code.
Start with the raw material: 314,661 people, 148,029 housing units, and a housing stock whose middle home was built in 1975. That single date organises everything on this page. On one side of it stand the older districts — 29.6% of homes predate 1960, 58.5% predate 1980 — heated and cooled by systems renewed in pieces for decades, in homes across Botetourt, Craig, Franklin, Roanoke, Roanoke city, Salem city. On the other side, the 16.6% built since 2000 run matched modern equipment, and fail in the newer ways. A Roanoke technician reads a home's build year the way a doctor reads a chart: it predicts, before a single panel is opened, which systems deserve suspicion first.
The pre-1980 stock is where most of the metro's HVAC character lives. Homes from those decades in Botetourt County and across Botetourt, Craig, Franklin, Roanoke, Roanoke city, Salem city were built with duct layouts from the first age of central systems, furnaces and condensers that have since been renewed piecemeal, and insulation standards from another era, and each of those choices is now at or beyond the age its makers expected of it. Owner-occupiers hold 68.7% of the metro's homes, so most of the people reading this page are reading about a system they own outright — one whose failures arrive as surprises only if nobody has looked at the pattern: cooling fading a little each summer, a furnace recovering a little more slowly, one room drifting a little further from the thermostat.
The newer side of Roanoke — the 16.6% of homes built since 2000, concentrated around growing communities like Roanoke — runs on matched modern systems that age more gracefully but fail in their own ways: heat pumps and condensers worked hard by 1,368 cooling degree days of hot-season demand, control boards and sensors wearing out in houses that all reach the same age at the same time. One metro, two equipment generations, and the sections below take them in the order this metro's data ranks them.
The climate written over all of it comes from the NOAA station at ROANOKE RGNL AP, VA US: an average year brings 3,868 heating degree days, 1,368 cooling degree days and 42.82 inches of precipitation. Those are not abstractions to a furnace or a condenser — they set how many hours a heating system runs each winter, how hard a cooling system cycles in July, and how much moisture every coil has to pull out of the indoor air. The problem sections that follow are selected by exactly these numbers, combined with the housing-age profile above.
Housing eras and climate, joined — the two datasets every section of this page is built from.
The distribution, in one breath: of every hundred Roanoke homes, 29.6 were standing before 1960, 28.9 went up in the two decades after, 24.9 in the two after that, and 16.6 have arrived since 2000. Percentages flatten the picture, so hold the counts beside them — 43,817 oldest-era homes, 24,573 newest — and the metro's heating and cooling stops being an abstraction: it is that many systems, of those ages, failing in that order.
Vintage is destiny in this metro. With the pre-1960 band the largest of the four, the centre of gravity of Roanoke's heating and cooling sits in houses whose systems have already outlived several generations of equipment — ducts gone leaky inside walls, furnaces renewed and renewed again, cooling retrofitted into floor plans that never imagined it. The later bands matter, and the post-2000 subdivisions will write their own chapter in time, but the calls that define HVAC here come disproportionately from the oldest streets, and they will keep coming until that stock is modernised system by system.
The second band in the table is the 1960-1979 stock: 42,780 homes, 28.9% of the metro. It is the transition generation — cooling arriving, heating generations overlapping, ducts mixed street by street — and it supplies Roanoke with its most diagnostic HVAC: two homes of the same year needing opposite answers, decided by what the builder happened to specify.
Start the climate half where the system starts: at the thermostat's two seasons. Roanoke's cooling answers 1,368 cooling degree days of load and its heating answers 3,868 heating degree days of cold at ROANOKE RGNL AP, VA US — an average temperature of 58.1 degrees that no individual week actually delivers. A heating and cooling system here is never in neutral; the record keeps it working at one end or the other all year.
A profile is only useful if it predicts something, and this one predicts the shape of an HVAC diary in Roanoke: which streets will call about cooling, which about heating, which about airflow, and in which months. Everything after this section is that prediction written out as services, problems and answers — the numbers first, the narrative second, the way the evidence actually runs.
Ranked for this metro alone, from its Census housing profile and NOAA climate record.
Planning is where households regain the advantage. A Roanoke homeowner who knows their system's refrigerant, age and repair history can run the transition on their own schedule: service the current machine properly, watch the leak-and-wear indicators, and time any replacement for a shoulder season, chosen equipment and an unhurried installation. The homeowner who meets the transition for the first time through a breakdown meets it on the calendar's worst terms — mid-heat, limited deliberation, a decision between an expensive charge on an old machine and a replacement nobody had budgeted to choose that week. The transition itself is the same in both stories; the difference is purely when the household chose to read the nameplate. Technicians in this metro can recite both versions from memory, street by street, because the metro's equipment generations were installed street by street.
Judge a refrigerant-era system by its leak history and its trend, not by a single charge reading. One low reading after many tight years is an event; a pattern of small losses is a biography, and the biography is what the economics should be based on. Roanoke's climate record loads the question at both ends — a leaking system underperforms exactly when ROANOKE RGNL AP, VA US's 30.4 hot days demand its full capacity, and its owner pays for refrigerant and lost performance simultaneously. The households that navigate this transition well keep one habit: they can state their system's age, refrigerant and last three repairs without looking them up. That small command of the facts converts an industry-wide generational change into a single household's managed decision, which is the scale at which it was always going to be decided anyway.
The regulatory facts are the foundation: R-22 production and import ended in the United States in 2020, leaving reclaimed stock as the supply, while new equipment has moved through R-410A to the current lower-impact generation. In Roanoke every generation still stands in service — the transition is not coming to this metro; it is distributed across it, yard by yard.
There is also a quieter loss running underneath the comfort loss: what leaks out was paid to condition. Every run of the system heats or cools a volume of air; the share that escapes into the attic or crawl space is work done for no room, repeated cycle after cycle, season after season. In a Roanoke home the arithmetic is worst exactly when the load is highest — the 30.4 hot days push the longest runs through the hottest attics — so the loss curve and the demand curve rise together. Sealing is unglamorous work: mastic on joints, connections re-made and supported, insulation restored where it has fallen. But it is one of the few interventions whose benefit the household can feel at the register on the first run afterward, in air that arrives at the temperature and volume the system produced.
Households judge their heating and cooling at the thermostat, but the thermostat only reports the room it sits in. Judge the system at its furthest register instead: the air arriving there, its temperature against the supply at the unit, its volume against the room's need. In Roanoke that furthest room is the honest auditor of the duct network — it inherits every leak, every sag and every degree of attic heat between it and the air handler. The homes whose far rooms match their near rooms have networks that were sealed when they were built and checked as they aged. The homes whose far rooms lag are not necessarily homes with weak equipment; they are homes whose delivery network has been quietly resigning, joint by joint, while the equipment took the blame and the service calls. The register, not the nameplate, is where the resignation is announced.
The load figures complete the case: 1,368 cooling degree days and 3,868 heating degree days at ROANOKE RGNL AP, VA US mean the network is in service in earnest at both ends of the year. Duct loss here is not a summer inefficiency or a winter one; it is a twelve-month tax on a system that works both seasons.
Ageing also changes what a repair means. On a young system, a failed part is an interruption; on an old one, it is information — a data point about the machine's remaining life and about whether the next failure is already loading. In the older districts of Roanoke, around Roanoke and the streets that grew with it, technicians read repairs that way and say so: this motor can be replaced, and here is what its failure tells us about the compressor behind it. The household's decision — maintain, repair, or plan a replacement on a calm schedule — is only as good as that reading. Systems do not owe anyone a warning before their last season, but in practice they file their intentions in a language of rising run times and narrowing margins, for those who have the readings taken.
The mechanics of ageing are unglamorous and cumulative. Bearings wear and draw more current. Capacitor values drift downward year by year, weakening every start they assist. Coil surfaces oxidize and foul, shedding their ability to exchange heat a fraction at a time. Refrigerant leaves through seals and joints at a pace too small to notice in a season and large enough to matter in five. Electrical connections loosen under thermal cycling and add resistance that becomes heat. None of these processes stops, but most of them are measurable long before they are fatal — which is precisely what separates maintenance from repair. A tune-up measures the drift; a repair replaces whatever the drift finally claimed. The household that buys measurement regularly buys the choice of when to spend on renewal, and that choice is worth the most on the oldest equipment.
The housing record is the evidence: 29.6% of Roanoke's homes predate 1960 and 58.5% predate 1980. Equipment lives and ages inside that stock, so the metro's systems are, as a population, exactly as old as its building history says they should be.
Twice a year, Roanoke changes its mind. The shoulder seasons — the weeks when a house can need heating in the morning and cooling by afternoon, sometimes within the same day — ask more of a system and its household than either deep season does: both modes in working order at once, controls set for change rather than for a settled pattern, and equipment that may sit idle for stretches and then be called on without ceremony. The record at ROANOKE RGNL AP, VA US frames the workload honestly — 3,868 heating degree days against 1,368 cooling degree days, a genuinely two-season climate — and the shoulders are where the two halves meet and negotiate. The checks that matter are changeover checks: the season just ending reviewed for what it spent — the filter, the wear items, the symptoms it filed — and the season arriving proven before it is needed, with a full run in the new mode while the weather is still forgiving. The thermostat's program belongs in the same check; last season's schedule, carried forward unexamined, is how a house ends up heating against an open-window afternoon. Households that treat the shoulders as their maintenance seasons get two calm, well-timed looks at their system a year — which is exactly the rhythm the equipment's manufacturers had in mind.
The season loads Roanoke's systems the way its record at ROANOKE RGNL AP, VA US says it will: 3,868 heating degree days against 1,368 cooling degree days in an average year, against a housing stock whose median build year is 1975. The households that read the season early — filters, drains, a system run before the extreme weeks — are the ones whose calls stay schedulable.
In Roanoke the transition's map is the housing map, lagged by one equipment generation. The districts built around Roanoke and the the 1970s streets hold the metro's R-22 veterans, in homes that have already seen one full cycle of this story when the equipment before them was young. The middle suburbs hold the R-410A majority. The 24,573 homes built since 2000 carry early current-generation systems now reaching the age where their first major repairs will be quoted — into a market whose standard has already moved on again. Read as a whole, the metro's 148,029 housing units contain the refrigerant industry's last several decades standing in rows, and the service economy of the metro is, in part, the business of keeping all those decades running at once. The deep pattern for a homeowner is simple to state and slow to change: your system's generation is a property of your street's building era, and its implications were installed with the house.
Read the ranking backwards and it reads as a data summary: 314,661 residents in 148,029 housing units, 29.6% of the housing from before 1960, 42.82 inches of rain in an average year. The pattern leads because the exposure is broad — counted not in individual unlucky houses but in whole eras of the metro's building, stacked one on another.
Experienced local practice starts with the simple certainties — the observations that take minutes and decide the most:
Ordered by what this metro's data says its homes need most.
Every repair through TempReach USA follows the same order: diagnosis at the equipment, findings explained, quote given before work begins, and a full test cycle before the technician leaves your Roanoke home.
Ask what fills an AC repair diary in Roanoke and the answer is written in its housing. The median home was built in 1975, and a good share of the metro's cooling equipment is older than the homes' current owners realise — units sized for a different era of insulation, charged with refrigerant generations that have since been phased down. A system in Botetourt County that cools a little less each summer is telling a story in instalments, and the repair visit reads the whole story: pressures, airflow, the coil's condition, the duct losses behind the walls. It is why two Roanoke homes of the same age, on different streets, so often need the same visit in the same year.
The local caseload behind this service is written in the climate figures: 1,368 cooling degree days a year and 30.4 days at 90 or above, pressing on a cooling fleet whose oldest members serve the 86,597 pre-1980 homes — in Cave Spring (26,014 residents) as much as in the oldest districts.
Post-renovation is the clearest case in the trade. Drywall dust and sanding residue settle through every open register, and one thorough cleaning after the work ends removes in hours what the system would otherwise circulate for years.
What comes out of a Roanoke duct system tells the home's biography: drywall dust from the renovation, pet hair in proportion to the household, the fine grit that 42.82 inches of yearly rain and the dry seasons between them work into every return. Cleaning matters most where the biography is long — the pre-1980 homes, 58.5% of the stock — and where a household's breathing argues for it. A technician who shows the before and after, and says plainly when a system does not need the work, is the one whose advice holds up. Count it in homes if you prefer: 86,597 built before 1980, 24,573 since 2000, one shared system of streets and seasons.
Duct demand concentrates in the metro's long-biography homes: 86,597 pre-1980 systems that have carried decades of household air, and the renovated homes around Hollins (17,005 residents) whose construction dust is still in the runs.
A tune-up is scheduled while the system still works, which is the entire point: measurements taken in mild weather find the parts that hard weather would have found instead, at its own chosen hour.
Maintenance in Roanoke is a calendar with two appointments a year, written by the climate: one before the 30.4 hot days arrive, one before the 76.6 freezing nights do. The cooling visit works the outdoor unit — coils washed, refrigerant pressures read, capacitors and contactors tested, the condensate drain cleared before the humid weeks can clog it. The heating visit works the furnace or heat pump — burners and ignition, the exchanger's condition, venting, airflow. Between them they catch the failures this metro's systems rehearse every year, while those failures are still small. The ROANOKE RGNL AP, VA US record — 3,868 heating degree days, 1,368 cooling — is the backdrop Botetourt County technicians plan around.
The maintenance caseload is the installed base itself: 148,029 housing units whose systems each face 30.4 hot days and 76.6 freezing nights a year. Around Rocky Mount (4,926 residents) as in the old core, the twice-yearly visit is what stands between that calendar and the emergency diary.
In Roanoke, air work follows the climate ledger: 3,868 heating degree days dry the indoor air out each winter while 1,368 cooling degree days load it with humidity each summer — most homes here need the humidity answer in both directions across the year.
Across 32 ZIP codes, Roanoke heating stock reflects a median build year of 1975 — furnaces at every age, each diagnosed on its own sequence and condition rather than its birthday.
With a median build year of 1975, many Roanoke systems are reaching replacement age together; the professional you are connected with inspects ducts and electrics across 32 ZIP codes before recommending equipment.
Heating installation in Roanoke starts with a heat-loss calculation across Botetourt, Craig, Franklin, Roanoke, Roanoke city, Salem city: the independent local professional measures the home's loss, inspects ducts and venting, and quotes the full scope before work begins.
Heat pump services in Roanoke test the whole year-round system: the independent local professional covering Botetourt, Craig, Franklin, Roanoke, Roanoke city, Salem city reads charge and airflow in both modes, proves defrost, and checks auxiliary heat logic before quoting any work.

From Roanoke to the metro's edge, Roanoke's 148,029 homes run every system type there is — single-stage furnaces, two-stage equipment, heat pumps with auxiliary heat — and each gets a control matched to its terminals, not a shelf guess.
One call from anywhere in Roanoke's 32 covered ZIP codes reaches the routing: the failure's details taken, safety advice given on the spot, and the visit sequenced the same way everywhere — safety, stabilization, diagnosis, then repair or an honest scope.
In Roanoke, commercial work follows the stock: 148,029 housing units' worth of mixed buildings — offices, retail and restaurants from Roanoke across the 32 covered ZIP codes — each with rooftop units whose service rhythm the local professional sets per building.
If this page's services were ranked by Roanoke's call patterns rather than listed in catalogue order, they would come out much as they do here — because the ranking behind them is data, not habit. The refrigerant transition reaching older systems leads the metro's problem table and leaky ducts losing air and energy follows, so the services answering them lead the list. The long tail of a metro's HVAC life — thermostat calls, duct questions, the one room that never matches the rest — fills in the diary around them, here as everywhere.

Read the grid as a building programme spread over a century. The oldest communities sit where the metro began; the youngest are still adding streets at its edge; and Cave Spring and Salem, with 26,014 and 25,477 residents, stand for the rings in between. Each ring was fitted in its era's equipment, and each is now failing, wearing or holding in its era's characteristic order. The ZIP codes below draw the coverage boundary; the eras inside it draw everything else on this page — the problems ranked, the services ordered, the checks advised.
Beyond the largest communities sit Hollins (17,005), Vinton (8,038), Rocky Mount (4,926), North Shore (3,708), Daleville (3,166) — smaller places across Botetourt, Craig, Franklin, Roanoke, Roanoke city, Salem city, covered on the same terms. Their housing tends to be older on average than the big suburbs', and their calls follow the older patterns on this page. One routing covers them all: find your ZIP code below and the rest is a phone call.
The metro's weight is not evenly spread. Roanoke holds 98,677 of the 314,661 residents; Cave Spring and Salem add 26,014 and 25,477; and the remainder scatters across the smaller places above, some no bigger than a few thousand people. HVAC follows the weight — most calls come from where most homes are — but era matters more than size: a small community of 1960s housing generates older-system work than a large new subdivision does.
Draw the metro by its paperwork and it resolves into Botetourt, Craig, Franklin, Roanoke, Roanoke city, Salem city — 6 jurisdictions sharing one housing stock and one weather system. Botetourt County holds the historic centre and the densest share of the older homes; the surrounding counties hold the rings of growth around it. Permits and inspections follow those boundaries even though temperature never does, which is part of why the technician this page connects you to works these streets specifically.
Three neighbouring coverage areas begin where this one ends: Blacksburg, VA, some 32 miles off; Lynchburg, VA, 48 miles; and Charlottesville, VA, 94 miles. Each keeps its own page because each keeps its own numbers — a different median build year, a different climate station, a different problem ranking. Boundary households should trust the ZIP list over the map: the code, not the compass, assigns the dataset.
The region around Roanoke is a set of variations on its theme: Blacksburg, VA, 32 miles off, runs a median build year of 1981 on a metro population of 181,616; Lynchburg, VA (48 miles) medians 1980 on 269,169; Charlottesville, VA (94 miles) medians 1988 on 228,597. Nearness is not sameness — a few decades of median build year separate their heating and cooling as surely as the miles separate their maps.
Count the metro per unit of itself: 4,626 housing units per covered ZIP code; 21,690 households per county; 14 communities sharing 6 county governments. Then weigh the generations against each other — 3.5 older homes for each newer one — and the service pattern on this page stops being a list and becomes a proportion: that much of the diary written by ageing systems, the rest by young ones wearing in.
One line of Roanoke arithmetic — a median home 51 years old · 89,407 owner-occupied homes against 40,734 renter-occupied · 1,369 pre-1960 homes for every covered ZIP code · a heating-to-cooling degree-day ratio of 2.83 · 1,088 mm of rain in an average year.
