The median Logan home was built in 1990; 40.6% of the stock predates 1980, and the pattern this metro's own data ranks first is heating failure risk when temperatures freeze. 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: 151,746 people, 50,576 housing units, and a housing stock whose middle home was built in 1990. That single date organises everything on this page. On one side of it stand the older districts — 19.6% of homes predate 1960, 40.6% predate 1980 — heated and cooled by systems renewed in pieces for decades, in homes across Franklin, Cache. On the other side, the 35.0% built since 2000 run matched modern equipment, and fail in the newer ways. A Logan 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.
Ask how Logan's older homes have been kept comfortable and the honest answer is: in pieces. A furnace here, a condenser there, one room's ducts renewed while the rest of the system carries on — across 20,534 pre-1980 homes, the patchwork is the norm rather than the exception. That history is written in the attics of Franklin County and everywhere else the early stock stands: systems that are part original, part renewed, and entirely individual. It is also why the guidance on this page keeps returning to patterns rather than single faults — in a patchwork system, the pattern is the diagnosis.
The growth side of the metro tells the opposite story in the same language. Smithfield, North Logan and the subdivisions still filling in account for much of the 17,702 homes built since 2000 — matched systems, planned ductwork, heat pumps where the lots suit them. Their HVAC is not old; it is uniform, which creates its own calendar: everything installed in the same boom reaches each wear point in the same years, from the first condenser replacements to the first control-board failures, while 557 cooling degree days of annual heat keep demand on the system high.
Over everything sits the weather, and here it is measured rather than described: NOAA's station at LOGAN CACHE AP, UT US averages 47.6 degrees across the year, with 45.2 days reaching 90 or more and 173.0 nights at freezing or below. A furnace feels that record as a season of relentless cycling; a condenser feels it as a summer without a quiet week; a heat pump feels both. The problem ranking below is what those numbers, crossed with the housing profile, produce for Logan specifically.
Two public records, one metro: what was built here, and what the sky does to it.
Break the stock down by building era and the profile sharpens. Before 1960: 19.6% of homes, roughly 9,913 of them. From 1960 to 1979: 21.0%, about 10,621. From 1980 to 1999: 24.4%, about 12,341. Since 2000: 35.0%, about 17,702. Four eras, four equipment generations — and the balance among them is this metro's HVAC character in a single paragraph.
New-stock metros have their own signature, and Logan has it in full: most homes built since 2000, most systems young, most HVAC work a matter of waves — the condenser wave, the control-board wave, the first furnace questions — arriving street by street as identical subdivisions age in lockstep. The older pockets still produce the deepest single jobs, but the metro's HVAC centre of mass sits in its newest postcodes, and every year the waves get closer together.
The runner-up era is 1980-1999, with 24.4% of homes. That stock has left its carefree decades and entered its maintenance decades, and it shows in the call pattern around Smithfield and the other districts of those years: condensers on their second cycle, furnaces reaching their wear points together, ducts still young enough to reward attention over replacement.
A profile needs its climate column, and Logan's comes from LOGAN CACHE AP, UT US: an average year of 47.6 degrees, built from extremes at both ends. The heating load (6,865 degree days) and the cooling load (557) together set the system's working life; the precipitation total (15.6 inches) sets the moisture the cooling half must remove; the freeze count (173.0 nights) sets the stakes of every heating failure. Four numbers — and most of the metro's HVAC behaviour follows from them.
That is the whole method of this page in one section: era shares from the Census, loads from NOAA, and a problem list that is simply where the two overlap most in Logan. The services and guidance that follow are ordered by the same profile — local first, generic last.

When heat does stop in a freeze, the household's first hour matters more than any other. The house's thermal mass buys time — hours, not days, in a hard Logan freeze — and the order of actions is worth knowing cold: confirm the system truly will not run through its simple causes, thermostat, breaker, filter, switch and fuel supply, because a share of no-heat calls end at one of those. Protect the water early where runs are exposed: taps on exterior walls dripping slowly, cabinet doors open to let room air reach the pipes, the vulnerable spaces given whatever warmth the home still holds. Know where the water main closes, before there is a reason to close it in the dark. And make the call promptly, describing the house's exposure honestly — a home with pipes in a crawl space and a falling thermometer is triaged differently from one that can coast until morning, and the call center can only sort by what it is told.
The physics of the risk run on a simple clock. A house loses heat through its envelope at a rate set by the temperature difference across it; in a hard freeze that difference is the widest of the year, so the indoor temperature of an unheated house falls fastest exactly when the consequences of falling are gravest. The fall is uneven: rooms over unheated spaces and against the wind cool first, wall cavities housing pipes cool faster than the rooms they serve, and a pipe can reach freezing beside a room that still feels merely chilly. That unevenness is the trap in a household's intuition — the thermostat's reading is the house's average story, while the pipes live in its coldest footnotes. In Logan the margin between a cold night and a damaging one is often a single night's depth of freeze against a house whose heat failed that morning, which is why the response sequence treats hours as the unit of value.
The climate record is the whole brief: 173.0 nights a year at or below freezing and 6,865 heating degree days at LOGAN CACHE AP, UT US. In Logan, a heating failure is never only a heating failure in those weeks — it is a timed exposure for every pipe the heat was guarding, and the record brings the test back annually.
There is a pattern to which furnaces fail in a cold snap: it is the ones that were already negotiating. The unit that locked out twice in December and recovered, the one whose blower grew loud in the season's first month, the one heating an the 1990s home whose ductwork was never generous — the snap does not create their problems, it schedules them simultaneously. In Logan a hard cold week therefore reads like a census of deferred maintenance, street by street. The households absent from that census share a habit rather than a budget: their furnaces were looked at before the season turned, by someone who treats an igniter's resistance reading and a flame sensor's condition as the forecasts they are.
Judge a furnace by its coldest week, not its kindest. In its coldest week a Logan furnace shows its true condition: whether it lights first time every time, whether it holds the house through the night without the temperature sagging, whether its sounds are the sounds it made when it was younger. LOGAN CACHE AP, UT US's record — 173.0 freezing nights in an average year — makes the examination annual and unsparing. Households that come through it without drama have usually done one unglamorous thing: they treated the autumn symptoms as the season's advance copy. A furnace rarely fails without having filed its intentions first, in a slower start, a louder cycle, a room that stopped keeping up. The winter merely publishes what the furnace had already written.
Housing adds its evidence: with a median build year of 1990, much of Logan's heating plant serves homes whose ductwork and insulation ask more per cold night than modern construction would. The furnace wears against the house as well as the weather.
Leaks are where the transition stops being abstract. A slow leak on a current-generation system is an ordinary repair story: find it, fix it, recharge. The same leak on an R-22 system in Logan opens a ledger. The refrigerant itself is drawn from a shrinking reclaimed supply; the system is, by definition, of an age where the leak may not be its last; and the money spent returning it to service buys time on a machine whose other components have aged alongside it. None of that decides the answer by itself — plenty of R-22 systems justify a repair and serve well afterward — but it changes the questions: how old is the unit, where is the leak, what else is worn, and what would the same money mean applied to a current-generation replacement? Households that ask those four questions with the numbers in front of them make the decision once; households that skip them often make it repeatedly, one hot season at a time.
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. Logan's climate record loads the question at both ends — a leaking system underperforms exactly when LOGAN CACHE AP, UT US's 45.2 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 Logan every generation still stands in service — the transition is not coming to this metro; it is distributed across it, yard by yard.
Living with a real winter, as Logan does, means the season has a shape: the first hard freeze finds the unprepared systems, mid-winter tests endurance — igniters, motors and sensors carrying months of cycles — and the late thaws reveal what the cold quietly damaged. Households that prove their heating in autumn and treat mid-season symptoms as scheduling information get through most winters with nothing dramatic to report; the drama concentrates, year after year, in the systems nobody ran until the night they were needed at full load.
The season loads Logan's systems the way its record at LOGAN CACHE AP, UT US says it will: 6,865 heating degree days against 557 cooling degree days in an average year, against a housing stock whose median build year is 1990. The households that read the season early — filters, drains, a system run before the extreme weeks — are the ones whose calls stay schedulable.
There is a statistical shape to the freeze week that the individual household never sees but every local technician knows: the calls do not arrive evenly across the cold. They cluster at the thaw's approach and in the cold's second and third days, as marginal systems exhaust their ability to recover and houses exhaust their thermal patience. The cluster is the metro's deferred maintenance arriving on a single schedule — the 6,865 heating degree days having audited every system simultaneously and published the failures together. That is the deepest argument for the calm-season rhythm this pattern keeps recommending: the freeze queue is the one queue in the trade that forms for everyone at the same moment, and the only reliable way to be absent from it is to have been early, in the months when absence was still a choice.
Strip the pattern down to its inputs and the ranking stops being mysterious: 47,988 households depending on systems installed across a median build year of 1990, in a climate that swings between 45.2 days of serious heat and 173.0 freezing nights. Whatever pattern a metro with those inputs manufactures most, it manufactures here — the lead position is less a title than a consequence, recalculated from the same public records any sceptic can check.
On a first visit for this pattern, a local technician's checks run in a practised order:
Ordered by what this metro's data says its homes need most.
An emergency is a trajectory, not a discomfort: temperatures heading somewhere unsafe, water in motion, an electrical fault worsening. Those failures cannot wait for a routine slot, and the response is sequenced accordingly.
Preparation is the quiet half of emergency work in Logan, and it is written in the metro's figures: a housing stock of 50,576 units, median vintage 1990, spread over 24 ZIP codes, will produce its no-heat and no-cooling nights on a schedule the climate roughly predicts. The households that come through those nights with the least damage are rarely the lucky ones; they are the ones who know where the system's shutoffs and breakers are, keep the number where it can be found, and treat the system's small warnings — the odd noise, the short cycle, the room that drifts — as the appointments they were. Locally the workload concentrates where the stock is oldest — the districts built around the 1990s first.
The emergency caseload is written in the extremes: 45.2 days of serious heat and 173.0 freezing nights a year, against systems whose median home was built in 1990. In Smithfield as across the metro, the urgent calls arrive when the weather and the equipment's age meet.
Furnaces rehearse their failures: second-attempt ignition, shortening cycles, a louder blower. In Logan those early signs are the cheapest version of the repair, caught while the house is still warm.
Read Logan's furnace calls as a census and they mirror the housing: the the 1990s districts produce the exchanger and ignition work on equipment in its second or third decade; the growth subdivisions produce the control-board and sensor faults of newer, more electronic systems. Both are furnace repair, but they are different trades inside one name — which is why the technician's first questions here are about the home's age and the unit's, before a single panel comes off. Count it in homes if you prefer: 20,534 built before 1980, 17,702 since 2000, one shared system of streets and seasons.
Under Logan's winters lie 6,865 heating degree days a year, and the furnaces answering them include the ageing units of the 20,534 pre-1980 homes alongside the electronic systems of the new subdivisions. The repair diary in Hyrum reads both ends of that stock in a single week.
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 Logan home.
Air conditioning in Logan works against the local calendar: 557 cooling degree days a year at LOGAN CACHE AP, UT US, with 45.2 days at 90 degrees or more. The failures follow that load — capacitors and contactors worn by relentless summer cycling, refrigerant charges drifting low on systems that have served a decade of heat, condensate drains clogging in the humid weeks. The older districts run the oldest condensers; the subdivisions around Logan run matched fleets installed in the same seasons, and both sides of the metro meet the repair call on the hottest week of the year. With a median build year of 1990, most of the metro's 50,576 housing units are working through the same ageing curve.
Count the exposure from the Census side: a median build year of 1990 across 50,576 housing units means half the metro's air conditioners are older than the systems in the growth suburbs around Nibley, and summer runtime is the statistic that matters — the repair calls follow it street by street.
Logan homes heat through 6,865 heating degree days and cool through 557 cooling degree days a year, so the blower runs in both seasons and the ducts never rest — which is why what has settled in them matters here in every month, not just one.
From period homes near Logan to newer builds toward Hyrum, Logan's ductless projects serve the rooms central systems miss — additions, conversions and homes built without ductwork.
With a median build year of 1990, many Logan systems are reaching replacement age together; the professional you are connected with inspects ducts and electrics across 24 ZIP codes before recommending equipment.
From Logan to Hyrum, Logan installations routed through TempReach USA finish with commissioning — combustion, temperature rise and airflow verified — so the fitted system is the specified system.
Across 24 ZIP codes and housing from a median build year of 1990, Logan heat pumps are specified and serviced from heat-loss figures and low-temperature performance data, not nominal tonnage.
Across Franklin, Cache, the housing split decides the starting point: older, leakier homes around Logan usually need filtration and moisture work first, while tighter newer builds in the 24 covered ZIP codes usually need deliberate ventilation most.
In Logan, the thermostat question splits by housing era: homes from around the median build year of 1990 often lack a common wire in the wall, while newer builds across the 24 covered ZIP codes usually carry one — the local professional checks the cable before choosing the control.
In Logan, the maintenance calendar writes itself from the climate: 6,865 heating degree days and 557 cooling degree days mean both systems work a real season, so the fall and spring visits each have genuine work to inspect.
Across Franklin, Cache, one climate ledger drives the calendar: 6,865 heating degree days and 557 cooling degree days mean roof units work both seasons hard, so the spring and fall visits each carry a full checklist here.
Ask where this metro's HVAC diary fills up and the answer is a short story: Heating failure risk when temperatures freeze first, furnace wear in hard cold close behind, and the services that answer them doing the bulk of the booked work. Everything else on the list above is the supporting cast — necessary, frequent enough, but not what Logan's housing stock, at its age and in its climate, principally demands. Read the service list as a weather report for the metro's systems and it stops looking like a catalogue.

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 Smithfield and North Logan, with 14,033 and 11,228 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.
The map continues: Hyrum (10,022), Providence (8,675), Nibley (7,651), Preston (5,800), Hyde Park (5,410). Different names, different decades — each community in Franklin, Cache was fitted with heating and cooling in its own growth years, which is why two streets in the same metro can need entirely different HVAC conversations. The ZIP list below is the working definition of coverage; the housing behind each code is the working definition of the job.
The metro's weight is not evenly spread. Logan holds 53,923 of the 151,746 residents; Smithfield and North Logan add 14,033 and 11,228; 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.
Administratively the metro is drawn from Franklin, Cache — 2 in all — with Franklin County at its centre. County lines do not change how a system runs, but they do shape the paperwork around the work: permits, inspections and code details are county and city business, which is one reason the professional who serves your street is a local one.
This page ends at the metro boundary, but the region does not: Ogden, UT, Salt Lake City, UT and Provo, UT continue the coverage in their own directions, each with a profile built from its own Census and NOAA figures. If your home sits near the line between metros, go by your ZIP code — it places you in the dataset that describes your housing.
The region around Logan is a set of variations on its theme: Ogden, UT, 57 miles off, runs a median build year of 1990 on a metro population of 672,784; Salt Lake City, UT (103 miles) medians 1986 on 1,308,377; Provo, UT (143 miles) medians 1999 on 773,426. Nearness is not sameness — a few decades of median build year separate their heating and cooling as surely as the miles separate their maps.
Ratios tell the metro's story compactly. Renters occupy 35.2% of homes; owners hold the rest. For every home built since 2000 there are 1.2 from before 1980. Spread the stock across the coverage map and each ZIP code carries about 2,107 housing units — the density at which era patterns repeat street after street instead of scattering, and at which a routed round of calls stays inside a few districts.
One line of Logan arithmetic — a median home 36 years old · 31,096 owner-occupied homes against 16,892 renter-occupied · 413 pre-1960 homes for every covered ZIP code · a heating-to-cooling degree-day ratio of 12.32 · 396 mm of rain in an average year.
County pages carry the local detail — land area, climate normals and the heating and cooling pressures on the ground in each county.
