A metro's heating and cooling is a portrait of its building history under its weather, and Pittsburgh's portrait is painted below from its own records: Census housing figures, NOAA climate normals, the metro's ZIP codes and communities. TempReach USA's role is the connection to a local professional; the portrait is here so that connection starts from understanding rather than urgency.

The median Pittsburgh home was built in 1960; 73.5% of the stock predates 1980, and the pattern this metro's own data ranks first is leaky ducts losing air and energy. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving your ZIP code.
Two numbers frame everything that follows: 70.5% of Pittsburgh homes are owner-occupied, and the median one was built in 1960. Ownership matters to HVAC because owners inherit their systems whole — every equipment decision a builder made in the 1960s or earlier is still in the attic, the closet and the side yard, ageing on its original schedule. With 73.5% of homes predating 1980 and 11.6% arriving since 2000, the metro is really two housing stocks sharing one map, and they are taken separately below before the problems are ranked.
The pre-1980 stock is where most of the metro's HVAC character lives. Homes from those decades in Allegheny County and across Allegheny, Armstrong, Beaver, Butler, Fayette, Lawrence, Washington, Westmoreland 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 70.5% 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.
Growth wrote this metro's newest HVAC chapter in matched equipment and planned ducts: systems sized as a single design, controls by the catalogue, outdoor units placed by the plat across the subdivisions near Bethel Park municipality and Monroeville municipality. The chapter is young — its systems have decades in hand — but it is not exempt from the metro's arithmetic: 826 cooling degree days of demand work its condensers hard, and the winters test its heat pumps with the same cold that tests the oldest furnace in Allegheny County.
The weather's part in this is written at PITTSBURGH ALLEGHENY CO AP, PA US, where an average year carries 41.34 inches of precipitation, 8.4 days at ninety degrees or more and 105.8 nights at freezing or below. Systems experience that year as workload and as stakes in roughly equal measure — the workload in the run hours, the stakes on the single coldest night and the single hottest week. The problem ranking further down is simply the housing profile above, read under this sky.
Housing eras and climate, joined — the two datasets every section of this page is built from.
Lay the eras side by side instead: 50.4% pre-1960 (589,589 homes), 23.1% from 1960-1979 (270,228), 14.9% from 1980-1999 (174,303), and 11.6% since 2000 (135,699). No single era tells the story — the proportions among them do, and those proportions are different in every metro this site covers.
This is, by the numbers, an old-system metro. The largest slice of its housing predates 1960, which means the typical serious job here involves equipment generations in their final chapters: ducts that leak by modern standards, furnaces renewed into them more than once, cooling added decades after the houses were built for heat alone. The newer bands exist — the growth since 2000 is real — but they are the supporting cast. Pittsburgh's HVAC identity was fixed by its earliest builders, and its problem list is written in their floor plans.
Close behind the leader come the 1960-1979 homes, 23.1% of the stock. Their systems are mid-change by construction — the decades when cooling spread mid-stream — so this band is where a Pittsburgh technician earns the diagnostic fee: airflow readings and pressure tests that say which side of the transition a given house was built on.
Start the climate half where the system starts: at the thermostat's two seasons. Pittsburgh's cooling answers 826 cooling degree days of load and its heating answers 5,406 heating degree days of cold at PITTSBURGH ALLEGHENY CO AP, PA US — an average temperature of 52.4 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.
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 Pittsburgh. The services and guidance that follow are ordered by the same profile — local first, generic last.
Chosen by this metro's own housing and weather data — the same two records this whole page is built from.
Duct loss hides inside other complaints. It presents as an air conditioner that cannot keep up in July — because the supply run through the attic is delivering air that picked up heat the whole way there. It presents as dust that returns days after cleaning, drawn in through return leaks in the crawl space. It presents as a furnace that heats the basement ceiling handsomely and the bedrooms modestly. In Pittsburgh, where many homes route their ducts outside the conditioned envelope by design of their era, these presentations are common enough to have a standing place in a technician's first questions. Separating duct loss from equipment weakness takes measurement rather than opinion — pressures and temperatures at the registers compared with those at the unit — and the separation matters, because the remedies are entirely different and only one of them touches the actual loss.
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 Pittsburgh 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.
Consider the delivery assumption: every system in Pittsburgh was sized on the expectation that its air would arrive. With 73.5% of homes built before 1980 — and their networks renovated, extended and re-sealed by turns ever since — that expectation's reliability varies house by house, which is why the measurement, not the assumption, has to govern.
Every heating and cooling system ages, but in Pittsburgh the ageing is concentrated where the housing is. The Census profile behind this page records 73.5% of homes built before 1980 and a median build year of 1960, which means a large share of the metro's furnaces, air conditioners and heat pumps are working in homes that have already outlived one or two generations of equipment — and much of the current generation is itself well into its second decade. Age shows differently than breakdown. An older system loses capacity a little at a time: refrigerant circuits seep at joints that have vibrated for years, blower motors draw more to move the same air, heat exchangers carry scale and rust, and control boards soldier on with components that drift out of tolerance. The household experiences it as a thermostat that needs a lower setting than it used to, rooms that lag, and a system that runs longer to do less. Nothing has failed; everything has faded, and the maintenance question becomes an honest one: what is left in this machine, and what does it need to give it back?
Judge an ageing system by its trend line, never by its kindest day. On its kindest day — mild weather, light load — almost any system in Pittsburgh can still argue for itself. The trend line is written elsewhere: in run times lengthening season over season, in the setting creeping to hold the same comfort, in the rooms that quietly dropped out of the system's reach. PITTSBURGH ALLEGHENY CO AP, PA US's climate record ensures the trend will be tested at both ends of the year — 8.4 hot days and 105.8 freezing nights in an average year. The households that read their trend early choose the terms of the ending, whether that ending is a renewed component, a planned replacement in a shoulder season, or a few more good years bought with honest maintenance. The households that wait for the system's verdict receive it in the weather least suited to hearing it.
The arithmetic is straightforward: 1,169,819 housing units in Pittsburgh, a median build year of 1960, and equipment that turns over far more slowly than it ages. At any given moment, a large share of the metro's systems are in the second half of their working lives — being maintained there, or being discovered there.
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 Pittsburgh 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.
A transition-aware service visit has a recognizable order. First, identification: the nameplate's refrigerant, model and year, stated aloud so the household and technician share the fact. Second, the leak question, taken seriously — a system low on charge has a leak until proven otherwise, and recharging without finding it is buying the same refrigerant twice on an installment plan. Third, the condition audit around the failure: compressor health, coil condition, electrical wear, because the decision the household faces is about the whole machine, not the one part that stopped. Fourth, the comparison itself, presented as what it is — the repair path with its realistic horizon, the replacement path with its — so the choice is made on the machine's merits and the household's plans for the home. In Pittsburgh that conversation, held in a calm season, is unhurried and genuinely optional-feeling; held in a heat wave, the same facts arrive wearing a deadline.
Count the generations the way a technician's route does: a single Pittsburgh street can hold an R-22 veteran, two R-410A systems and a current-generation installation within a few doors. The service records of one metro contain the whole transition — which is why identification, not assumption, opens every diagnosis here.
A furnace earns its keep in the weeks a Pittsburgh winter stops being polite. The record at PITTSBURGH ALLEGHENY CO AP, PA US counts 105.8 nights a year at or below freezing and 5,406 heating degree days across the season, and in the coldest stretches a furnace that idled through autumn runs nearly without pause. That duty wears the parts that move and the parts that ignite: inducer and blower motors accumulate hours, igniters cycle thousands of times, flame sensors foul a little with every firing, and heat exchangers expand and contract through temperature swings that test their metal daily. The failures that follow have a rhythm homeowners recognize — a furnace that lights and quits, one that runs but heats unevenly, one that was fine in November and silent in the coldest week of January. Cold does not usually break a sound furnace; it collects the wear the furnace had been carrying quietly, and it collects at the moment the household can least spare the heat.
A technician reading a tired furnace works from the safety chain outward. Modern furnaces report themselves through lockouts and fault codes, and the pattern of the lockout is the first text: ignition failures point one way, overheating shutdowns another, pressure-switch faults toward venting and condensate. In cold weather the venting branch matters more than households expect — snow, ice and wind can obstruct terminations, and a furnace that will not prove its draft will not fire, by design. The heat exchanger inspection belongs in the same visit whenever age or overheating symptoms suggest it, because a cracked exchanger is the one finding that changes the conversation from repair to replacement on safety grounds. What looks from the hallway like 'the furnace stopped' resolves, under a practiced sequence, into one worn branch of a short list.
Count the duty rather than the drama: a Pittsburgh furnace fires through 5,406 heating degree days a season, cycling its igniter and swinging its heat exchanger with every call. The wear that surfaces in January was purchased, cycle by cycle, in the seasons before it.
A heating failure in mild weather is an appointment. The same failure in a hard freeze is a countdown, because a house without heat in Pittsburgh's coldest weather is losing temperature toward the point where its plumbing becomes the next casualty. The record at PITTSBURGH ALLEGHENY CO AP, PA US — 105.8 nights a year at or below freezing and 5,406 heating degree days across the season — says the exposure is not hypothetical here. As indoor temperature falls, the spaces that go first are the ones the heat reached last: pipes in exterior walls, runs through crawl spaces and garages, the plumbing of additions and rooms over unheated ground. A burst pipe discovered at the thaw converts one breakdown into two trades' worth of damage, which is why freeze-season heating calls run on different logic from every other call of the year: restore heat or protect the house, in that order, with no step treated as routine. Knowing the sequence before the night it is needed — how to keep a house safer while help travels, when to drip taps, when to shut water down — is part of owning a heated home in this climate.
Judge a heating system's freeze readiness in the autumn, by evidence, not in January by outcome. The evidence is a short list: ignition proven under a real call for heat, the safety chain and fault history read rather than assumed, condensate and venting paths walked where the cold can reach them, backup heat exercised on a heat pump, and a household that knows its own water main and its own first hour by heart. PITTSBURGH ALLEGHENY CO AP, PA US's record — 105.8 freezing nights in an average year — is the examination date, published in advance. The homes that pass it without drama share the profile of having treated that date as real. A freeze does not grade on effort or intention; it grades the house and its heating plant exactly as it finds them, in the coldest hours, once a year, with the plumbing as the second paper. Preparation is simply the decision to sit the exam rehearsed.
The housing detail completes the case: with a median build year of 1960, much of Pittsburgh's stock routes water through exterior walls, crawl spaces and additions — placements that are unremarkable in October and decisive in a January freeze with the heat off. The risk is built in; only its management is optional.
What the shoulders reward is a habit of finishing seasons properly. The last cold week is the time to note the heating system's report card while it is still legible; the last hot week, the cooling system's. Between them sits a window — mild days, an unhurried diary for local technicians, a system that can be opened and tested without the household depending on it that night — that neither deep season gives. In Pittsburgh that window opens twice a year on a climate of 8.4 hot days and 105.8 freezing nights, and the households that use it convert the two most failure-prone transitions of the year into the two calmest appointments on their calendar.
The season loads Pittsburgh's systems the way its record at PITTSBURGH ALLEGHENY CO AP, PA US says it will: 5,406 heating degree days against 826 cooling degree days in an average year, against a housing stock whose median build year is 1960. 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 deeper reason duct problems persist unsolved in Pittsburgh: they are invisible by location and deniable by symptom. The network hides in the spaces nobody enters, and its failures present as the equipment's failures, so the system's most-serviced component — the furnace or air conditioner — absorbs attention that belongs to its quietest one. A metro with 1,169,819 housing units and a median build year of 1960 has, in effect, an equal number of duct networks ageing unobserved alongside the equipment everyone watches. The closer look this pattern rewards is empirical: a delivered-air measurement ends the argument in an afternoon. Until that measurement is taken, duct loss remains the diagnosis of exclusion — suspected last, confirmed rarely, and meanwhile invoiced daily in longer run times and uneven rooms.
Read the ranking backwards and it reads as a data summary: 2,443,921 residents in 1,169,819 housing units, 50.4% of the housing from before 1960, 41.34 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.
The first visit follows a short, diagnostic list — each item ruling a branch of the problem in or out:
Sequenced by this metro's own problem ranking, not by a national catalogue order.
A duct system remembers everything the house has done: the remodel, the shedding dog, the winter the filter went unchanged. Cleaning reads that memory out under vacuum pressure and leaves the airways themselves — not just the grilles — clean.
Duct cleaning in Pittsburgh is booked in waves that follow the housing: after the renovation seasons in the older districts, at move-in across the subdivisions, alongside system replacements everywhere. The work pairs naturally with the inspection that surrounds it — leaking joints found and sealed, a disconnected run in an attic discovered, insulation fallen where it should not be. The cleaning is the appointment; the findings are often the value. Ask in Plum and the answer rhymes with Pittsburgh: same eras, same equipment generations, same calendar of failures.
Count the systems and the diary fills itself: 1,059,751 households breathing through ductwork daily, the oldest of it in homes from the 1960s and the newest in the subdivisions past Bethel Park municipality. What the cleaning finds follows the biography — dust in proportion to years, debris in proportion to renovations.
One local habit worth copying: Pittsburgh homeowners who mention their street's building era when they book get a better-matched visit, because a technician heading to a the 1960s home in Allegheny County loads different parts than one heading to a new-build subdivision in Bethel Park municipality. The service is the same; the preparation is local.
The failures maintenance interrupts are unglamorous and specific — a condensate drain weeks from flooding, a capacitor drifting out of range, charge seeping from a joint. Each is a small job in spring and a breakdown in July.
Maintenance also has a paperwork virtue in Pittsburgh: the recorded visit. Readings dated season by season — refrigerant pressures, temperature splits, capacitor values, the exchanger's noted condition — turn a system's decline from a surprise into a schedule. Households across Allegheny, Armstrong, Beaver, Butler, Fayette, Lawrence, Washington, Westmoreland who keep those records meet replacements as appointments, and the technicians who write them are leaving the next visit, whoever makes it, a map of the system's life. In a metro of this size, that map is most of what local knowledge means. Locally the workload concentrates where the stock is oldest — the districts built around the 1960s first.
Tune-up demand follows the fleet's waves: the subdivisions' matched systems reaching service points together, the pre-1980 districts' individual units on individual schedules. Plum sits inside one of those patterns; the readings taken there this season predict its systems' next one.
In Pittsburgh this service is booked most often through the problem patterns at the top of this page — the metro's housing data, not habit, sets the order. If your home is in the 73.5% built before 1980, mention its age on the call: it changes the parts the technician loads before heading to Pittsburgh and the rest of the metro.
Ice on the line, a tripping breaker, run times that lengthen week by week — in Pittsburgh these are the early chapters of a cooling failure, and a diagnosis caught at that stage is usually a component, not a system.
Ask what fills an AC repair diary in Pittsburgh and the answer is written in its housing. The median home was built in 1960, 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 Allegheny 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. Count it in homes if you prefer: 859,817 built before 1980, 135,699 since 2000, one shared system of streets and seasons.
Count the exposure from the Census side: a median build year of 1960 across 1,169,819 housing units means half the metro's air conditioners are older than the systems in the growth suburbs around New Castle, and summer runtime is the statistic that matters — the repair calls follow it street by street.
Where this service gets booked in Pittsburgh follows the map on this page: the older districts generate the deep-end work, the post-2000 subdivisions the wear-and-tear work, and the 174,303 homes in between split the difference. Telling the call center your home's build decade — most Pittsburgh owners know it within a few years — puts the right kit on the van the first time.
Furnaces rehearse their failures: second-attempt ignition, shortening cycles, a louder blower. In Pittsburgh those early signs are the cheapest version of the repair, caught while the house is still warm.
Furnace work in Pittsburgh is set by 5,406 heating degree days a year at PITTSBURGH ALLEGHENY CO AP, PA US and 105.8 nights at or below freezing. The failures the season produces are the working parts wearing in sequence: igniters that have fired ten thousand times, blower motors tired from two seasons a year of duty — heating in winter, air handling in summer — heat exchangers stressed by decades of expansion and contraction. In the older districts, where 73.5% of the metro's homes predate 1980, many furnaces are replacements of replacements, fitted into ductwork older than the equipment itself. It is why two Pittsburgh homes of the same age, on different streets, so often need the same visit in the same year.
Heating demand in Pittsburgh concentrates where the cold does its work: 105.8 nights a year at or below freezing, against a housing stock whose median build year is 1960. Around Murrysville municipality as in the old core, that combination is not an abstraction — it is the street's furnaces, house by house.
One local habit worth copying: Pittsburgh homeowners who mention their street's building era when they book get a better-matched visit, because a technician heading to a the 1960s home in Allegheny County loads different parts than one heading to a new-build subdivision in Bethel Park municipality. The service is the same; the preparation is local.
Safety outranks repair, always. A gas smell or a carbon monoxide alarm means leaving the house and calling the utility or emergency services first — the repair visit comes after the house is safe to be in.
Emergency demand in Pittsburgh bunches, and the bunching is predictable from this page's data: heat waves load the ageing condensers of the pre-1980 districts, cold snaps find the tired igniters and cracked exchangers, storm weeks test every system the power surge reached. A local technician's emergency diary is the metro's housing and climate record with dates attached — which is why routed help, from a van already stocked for this stock's failures, is the fastest honest answer the night the system stops. In Pittsburgh that holds across 388 ZIP codes, from Pittsburgh out to Monroeville municipality.
Scale the problem by the Census count: 1,059,751 households depending on systems that cannot be improvised around — no heat in a freeze, no cooling in a heat wave. The emergency visit exists for the hours when waiting until Monday is not a plan, in McKeesport this month, somewhere else next.
Where this service gets booked in Pittsburgh follows the map on this page: the older districts generate the deep-end work, the post-2000 subdivisions the wear-and-tear work, and the 174,303 homes in between split the difference. Telling the call center your home's build decade — most Pittsburgh owners know it within a few years — puts the right kit on the van the first time.
Replacement in Pittsburgh begins with a load calculation across Allegheny, Armstrong, Beaver, Butler, Fayette, Lawrence, Washington, Westmoreland: the independent local professional measures the home — not the old unit's label — and quotes the full scope before work begins.
With 1,169,819 homes and a median build year of 1960, Pittsburgh heating stock spans every era of furnace and flue — each installation assessed on its own house, not on the outgoing unit's label.
From Pittsburgh to Plum, Pittsburgh heat pump calls through TempReach USA reach a local professional who explains findings plainly and quotes after assessing — in the heating season and the cooling season alike.
From period homes near Pittsburgh to newer builds toward Plum, Pittsburgh's ductless projects serve the rooms central systems miss — additions, conversions and homes built without ductwork.
With a median build year of 1960 across 1,169,819 homes, Pittsburgh holds both air problems at once — envelopes that leak air freely and envelopes sealed tight — and the local professional assesses which house yours is before recommending equipment.
From Pittsburgh to the metro's edge, Pittsburgh's 1,169,819 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.
In Pittsburgh, commercial work follows the stock: 1,169,819 housing units' worth of mixed buildings — offices, retail and restaurants from Pittsburgh across the 388 covered ZIP codes — each with rooftop units whose service rhythm the local professional sets per building.
If this page's services were ranked by Pittsburgh'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. Leaky ducts losing air and energy leads the metro's problem table and ageing systems in older homes 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.

The communities in the grid are not suburbs of the page; they are its subject as much as Pittsburgh is. Bethel Park municipality (33,070 residents) and Monroeville municipality (28,383) carry their own building decades, their own equipment generations and their own positions in the problem ranking's logic — a system under a Bethel Park municipality roof answers to the same data as one in the centre, but to a different era of it. Coverage here is defined by the ZIP list below; understanding is defined street by street, and this page's figures are the metro-wide version of a story each community tells in its own numbers.
Beyond the largest communities sit Plum (26,873), Allison Park (22,108), New Castle (21,727), Baldwin (21,159), Murrysville municipality (20,839) — smaller places across Allegheny, Armstrong, Beaver, Butler, Fayette, Lawrence, Washington, Westmoreland, 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.
Start with Pittsburgh itself: 303,620 residents, 12.4% of the metro — the centre the rest of the map orbits. Bethel Park municipality (33,070) and Monroeville municipality (28,383) form the next ring out, housing with its own building decades and its own equipment generations. Beyond them the metro thins into the smaller communities in the grid above, each a few thousand households deep — small in population, identical in one respect: their systems answer to the same eras and the same weather as the big city's.
The metro answers to 8 county governments (Allegheny, Armstrong, Beaver, Butler, Fayette, Lawrence, Washington, Westmoreland), a patchwork that matters at permit time rather than at the thermostat. Allegheny County carries the centre; the others carry the growth rings and the older outlying towns. A technician routed through this page works inside that patchwork daily — the weather does not care about the boundaries, but the job's paperwork does.
Three neighbouring coverage areas begin where this one ends: Erie, PA, some 110 miles off; State College, PA, 112 miles; and Chambersburg, PA, 124 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 Pittsburgh is a set of variations on its theme: Erie, PA, 110 miles off, runs a median build year of 1963 on a metro population of 265,832; State College, PA (112 miles) medians 1980 on 157,393; Chambersburg, PA (124 miles) medians 1978 on 160,652. 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: 3,015 housing units per covered ZIP code; 132,469 households per county; 14 communities sharing 8 county governments. Then weigh the generations against each other — 6.3 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.
The Pittsburgh record in one line — median home age: 66 years · owner-occupied homes: 747,124 · renter-occupied homes: 312,627 · pre-1960 homes per covered ZIP code: 1,520 · heating-to-cooling degree-day ratio: 6.54 · average rainfall: 1,050 mm a year.
County pages carry the local detail — land area, climate normals and the heating and cooling pressures on the ground in each county.
