The median New Orleans home was built in 1973; 64.7% 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.
Read New Orleans through its counties and the picture sharpens. Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish were not built in the same decades or for the same households, and their heating and cooling carries those differences: an older core where 31.2% of the metro's homes predate 1960, growth corridors where the subdivisions arrived in waves, and edges still being built out. The metro-wide medians — a middle home built in 1973, 463,532 housing units in all — are the average of those local stories, and the sections below are organised by the patterns the combined record produces, from the oldest equipment generations to the newest failure modes.
There is an equipment timeline buried in New Orleans's housing figures, and it reads like a technician's diary. The 144,622 homes from before 1960 were heated first and cooled later, their ducts added around floor plans that never imagined them. The 155,283 that followed between 1960 and 1979 mixed those retrofits with the first planned central systems. Then came the 92,243 homes of 1980-1999, fitted with matched systems as standard. Each band of that timeline is now a band of characteristic failures, arriving in the order the equipment tires — which is why a home's build year, in this metro, is the single most predictive fact about its heating and cooling.
The growth side of the metro tells the opposite story in the same language. Metairie, Kenner and the subdivisions still filling in account for much of the 70,920 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 2,615 cooling degree days of annual heat keep demand on the system high.
The weather's part in this is written at NEW ORLEANS ALVIN CALLENDER FL, LA US, where an average year carries 63.8 inches of precipitation, 64.4 days at ninety degrees or more and 10.8 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.
Break the stock down by building era and the profile sharpens. Before 1960: 31.2% of homes, roughly 144,622 of them. From 1960 to 1979: 33.5%, about 155,283. From 1980 to 1999: 19.9%, about 92,243. Since 2000: 15.3%, about 70,920. Four eras, four equipment generations — and the balance among them is this metro's HVAC character in a single paragraph.
The largest band of New Orleans homes dates from 1960 to 1979, and that band defines the metro's HVAC present: the decades when central air spread through ordinary housing, when duct systems were laid out for the equipment of the day, when furnaces and condensers began ageing as pairs. Those systems have been renewed unevenly since — a condenser here, a furnace there — so the assessment culture here is repair-versus-renew, home by home, because the mid-century stock refuses a single verdict for the whole street.
The runner-up band is the oldest one: 31.2% of homes, some 144,622 of them, standing from before 1960. HVAC in that band is heritage work — duct layouts and equipment generations that have outlasted their design lives — and it punches above its share in the metro's repair diary, because age, not headcount, sets the failure rate.
Start the climate half where the system starts: at the thermostat's two seasons. New Orleans's cooling answers 2,615 cooling degree days of load and its heating answers 1,425 heating degree days of cold at NEW ORLEANS ALVIN CALLENDER FL, LA US — an average temperature of 68.2 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 New Orleans. The services and guidance that follow are ordered by the same profile — local first, generic last.
Ordered by what this metro's data says its homes need most.
Age informs an AC repair decision without deciding it — a sound system with a failed motor earns its repair, and an honest diagnosis in New Orleans will tell you which side of that line your unit stands on.
Air conditioning in New Orleans works against the local calendar: 2,615 cooling degree days a year at NEW ORLEANS ALVIN CALLENDER FL, LA US, with 64.4 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 New Orleans 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. That is the daily reality for the 397,029 households spread across Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish.
Count the exposure from the Census side: a median build year of 1973 across 463,532 housing units means half the metro's air conditioners are older than the systems in the growth suburbs around Metairie, and summer runtime is the statistic that matters — the repair calls follow it street by street.
Clean ducts that leak are still leaking. The inspection folded into a cleaning visit finds the crushed flex run, the separated joint, the filter slot that never sealed — the conditions that decide whether cleaned air actually reaches the rooms.
A word on timing, since New Orleans households ask: duct cleaning earns its appointment when the evidence calls for it — after construction or renovation dust, when a home changes hands after years of one household's accumulation, when the registers show visible load or the blower compartment tells the story. Booked on evidence, it is honest work with visible results. Booked on a calendar superstition, it is a van ride. Local technicians who work from the evidence are the ones this page's routing favours, in New Orleans and across the metro alike. The 63.8 inches of rain in an average year here is part of the story too — humidity loads every cooling coil in the metro.
Duct demand concentrates in the metro's long-biography homes: 299,905 pre-1980 systems that have carried decades of household air, and the renovated homes around Marrero (31,866 residents) whose construction dust is still in the runs.
Moisture cuts both ways. Too little through a heating season cracks wood and dries airways; too much through a cooling season feeds what grows in damp corners. Whole-home control aims at the moving middle, set against the weather outside.
Air quality work in New Orleans also has a quiet economics of attention: the households that measure first — a hygrometer on the wall, the filter inspected monthly against the light — tend to need the least equipment, because they catch the simple causes early: the filter long past its season, the bath fan venting into an attic, the return pulling unconditioned air through a leaky duct in the pre-1980 districts. The assessment visit formalises that attention with instruments, and prescribes in proportion to what it finds. With a median build year of 1973, most of the metro's 463,532 housing units are working through the same ageing curve.
Air quality demand in this metro is written by its sealed seasons: 64.4 hot days with the windows shut around the cooling, 10.8 freezing nights with them shut around the heat. The 70,920 post-2000 homes hold their air tightest; the older districts around Terrytown exchange theirs with attics and crawl spaces.
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 New Orleans: 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 Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish 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. From Metairie to Kenner, the pattern repeats wherever the housing era matches.
The maintenance caseload is the installed base itself: 463,532 housing units whose systems each face 64.4 hot days and 10.8 freezing nights a year. Around Harvey (21,710 residents) as in the old core, the twice-yearly visit is what stands between that calendar and the emergency diary.
From New Orleans to Marrero, New Orleans replacements routed through TempReach USA end in commissioning — measured charge and airflow — so the installed system matches the calculated one.
From New Orleans to Marrero, a no-heat call through TempReach USA reaches a local professional whose visit includes the exchanger and venting checks that furnace work owes a New Orleans household.
Heating installation in New Orleans starts with a heat-loss calculation across Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish: the independent local professional measures the home's loss, inspects ducts and venting, and quotes the full scope before work begins.
From New Orleans to Marrero, New Orleans 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.
Ductless installation in New Orleans is surveyed room by room across Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish: the independent local professional calculates each space's load, plans line and drain routes, and quotes the complete design before work begins.
Across Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish, one climate fact shapes the configuration: 1,425 heating degree days against 2,615 cooling degree days tells whether the control's year is mostly a heating story, mostly a cooling story, or a genuine heat pump balancing act.
In New Orleans, emergency means weather-relative: 1,425 heating degree days put no-heat calls on a freezing clock each winter, while 2,615 cooling degree days make a dead system a health question each summer — the call center triages against both, using the hours shown on this page.
New Orleans's commercial buildings span every era around a median build year of 1973 — and with the era goes the equipment, from aging single units over old storefronts to multi-zone systems in new developments, all serviced from a per-unit record.
Two patterns generate most of the bookings behind the services above: The refrigerant transition reaching older systems and leaky ducts losing air and energy. That is why the order of this page's service list is what it is — the services answering those patterns come early, and the rest follow in the order the metro's data supports. A homeowner whose home matches the local profile — built in the metro's big decades, in one of its older districts — is, statistically, reading their own shortlist.
Chosen by this metro's own housing and weather data — the same two records this whole page is built from.
A generation change is moving through New Orleans's cooling equipment, and it arrives one repair decision at a time. For decades, residential systems ran on R-22; production and import of that refrigerant ended in the United States in 2020, so the supply that remains is reclaimed stock, and servicing a leaking R-22 system means weighing a scarce, aging refrigerant against the age of the machine it serves. Newer systems moved to R-410A, and equipment now arriving uses lower-impact refrigerants such as R-454B, with their own handling and code requirements. The transition matters to a homeowner at specific moments: when an older system needs a charge, when a coil or compressor fails on a machine whose refrigerant is effectively retired, when a repair quote must be compared honestly against replacement. Nothing about it is a reason for panic — R-22 systems are not banned from being serviced — but every significant repair on one is now also a planning conversation, and households in New Orleans with equipment from the R-22 era benefit from having it before the hottest week, not during it.
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. New Orleans's climate record loads the question at both ends — a leaking system underperforms exactly when NEW ORLEANS ALVIN CALLENDER FL, LA US's 64.4 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 New Orleans every generation still stands in service — the transition is not coming to this metro; it is distributed across it, yard by yard.
A duct system is a delivery network, and in many New Orleans homes it leaks like one. Supply runs carry conditioned air through attics, crawl spaces and wall cavities on their way to the registers; return runs carry it back. Every joint, seam and connection along those paths is a chance for the air to leave early or for unconditioned air to be pulled in, and older installations — assembled with tape that has long since dried out, or sections that have sagged apart — leak at many of them at once. The system responds the only way it can: by running longer to deliver the same comfort, which is why duct loss so often disguises itself as an equipment problem. The furnace and air conditioner get blamed, serviced, sometimes replaced, while the network between them quietly spills a share of every run into the attic. In New Orleans's housing, where duct runs cross some of the hottest and coldest spaces in the home, a leak counts double: the air is lost, and the air that remains arrives changed by the space it traveled through.
The construction details explain the timeline. Duct joints are mechanical connections, and the sealants asked to make them permanent have finite lives: cloth-backed tape dries and releases, foil tape lifts at edges, and even mastic can crack where runs move with the building. Flex duct, common in the metro's later building decades, fails at its connections and where its inner liner is pierced or crushed — and a crushed section quietly throttles every room downstream of it. Meanwhile the spaces the ducts cross work against them: attic temperatures in a New Orleans summer turn an uninsulated or leaking run into a heat exchanger pointed the wrong way, and winter reverses the argument in the crawl space. A duct system is therefore not a fixed asset but a slowly changing one, and its delivered performance in any given year is an empirical question, not a memory of its installation day.
The load figures complete the case: 2,615 cooling degree days and 1,425 heating degree days at NEW ORLEANS ALVIN CALLENDER FL, LA 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.
Cooling and drying are two jobs wearing one name, and in New Orleans the second job is the heavier one for much of the season. The climate record at NEW ORLEANS ALVIN CALLENDER FL, LA US pairs the heat with 63.8 inches of precipitation in an average year, and the air that comes with that moisture asks every air conditioner to do double duty: lower the temperature and wring out the water. A system dries air only while it runs, and only when its coil is cold and its airflow is right — so a unit that satisfies the thermostat quickly and shuts off can leave a house cool and clammy at the same time. The burden shows in the house as much as in the equipment: rooms that feel sticky at a normal setting, a musty note in closets and low corners, condensation on registers and windows, and indoor air that never quite feels finished. Households often answer by turning the thermostat down, which buys dryness with overcooling and longer bills of runtime. The underlying question is a moisture question — where the water is entering, how the system is set up to remove it, and whether the house needs dedicated dehumidification help beyond its cooling cycle.
The physics of the burden are worth stating plainly. Air holds water as vapor; the amount it can hold rises with temperature, which is why warm air arriving in a New Orleans summer carries so much of it indoors. A cooling coil removes moisture by passing air across a surface cold enough for water to condense on it — the same physics that beads a cold glass. Two conditions govern how much condenses: how long the air stays against the cold coil, and how cold the coil runs. Short cycles starve the first; high airflow can starve the second. Meanwhile the house keeps adding vapor from living and from its own damp places, and the envelope keeps trading air with the outdoors. Indoor humidity is the running balance of that account — removal by the coil against addition by everything else — and a house that feels damp is simply a house whose account is out of balance in the wet direction.
Housing stacks the burden: New Orleans's 299,905 pre-1980 homes bring crawl spaces, older envelopes and duct runs through damp air to the contest. The moisture a system must remove is set by the house it serves — and much of this metro's housing imports generously.
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 New Orleans, around New Orleans 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.
A serious look at an ageing system follows a short order. First, identity: the nameplate's age, model and refrigerant, because those three facts set the realistic horizon. Second, the electrical profile: starting components, motor draws, the condition of connections and the disconnect. Third, the air side: filter, coil cleanliness, blower condition and the temperatures across the system, which together say whether the machine is moving its rated air. Fourth, the combustion side on heating equipment: ignition condition, flame quality, exchanger inspection and venting. Last, the conversation those readings support — what is sound, what is spent, what to watch, and what the household should plan for in which season. In New Orleans's older housing that order matters more, not less, because the findings compound: an old system behind dirty coils and a drifting charge is three small problems impersonating one large one.
Climate presses the point. A system in New Orleans works both ends of the year — 1,425 heating degree days against 2,615 cooling degree days at NEW ORLEANS ALVIN CALLENDER FL, LA US — so its components accumulate in twelve months the wear a single-season climate would spread over two years.
What the humid months examine is the difference between a house and a sealed jar of wet air. New Orleans's 63.8 inches of average rain arrive unevenly, and the saturated stretches hold indoor moisture high against every system's ability to remove it. The evidence surfaces politely first — a closet's musty note, a mirror that clears slowly, registers that sweat on the most saturated afternoons — long before it surfaces as a breakdown or a mold conversation, which is why this season rewards the households that read the polite version. The tools are unglamorous: measured indoor humidity, a drain that flows, cycles long enough to dry, and moisture sources answered at the source rather than at the thermostat.
The season loads New Orleans's systems the way its record at NEW ORLEANS ALVIN CALLENDER FL, LA US says it will: 1,425 heating degree days against 2,615 cooling degree days in an average year, against a housing stock whose median build year is 1973. The households that read the season early — filters, drains, a system run before the extreme weeks — are the ones whose calls stay schedulable.
In New Orleans the transition's map is the housing map, lagged by one equipment generation. The districts built around New Orleans 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 70,920 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 463,532 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.
The numbers underneath it, for New Orleans: 463,532 housing units, a median build year of 1973, and a climate record at NEW ORLEANS ALVIN CALLENDER FL, LA US of 1,425 heating degree days against 2,615 cooling degree days. Cross the housing record with the weather record and this pattern is what falls out at the top — rarely the most dramatic problem in heating and cooling, but the one this metro's stock and climate manufacture most steadily.

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 Metairie and Kenner, with 138,995 and 65,113 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 Marrero (31,866), Laplace (28,480), Terrytown (25,844), Chalmette (22,447), Harvey (21,710) — smaller places across Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish, 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. New Orleans holds 376,035 of the 988,763 residents; Metairie and Kenner add 138,995 and 65,113; 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.
The metro answers to 7 county governments (Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish), a patchwork that matters at permit time rather than at the thermostat. Jefferson Parish 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: Slidell, LA, some 40 miles off; Houma, LA, 44 miles; and Baton Rouge, LA, 79 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.
Set New Orleans among its neighbours and the contrasts sharpen the profile: Slidell, LA — metro population 279,108, median build year 1995 — sits 40 miles away; Houma, LA (199,668, median 1982) 44 miles; Baton Rouge, LA (888,699, median 1989) 79 miles. Three different housing stocks under three nearby skies, which is why each keeps its own page and its own problem ranking rather than borrowing this one.
Divide the stock by the map and the densities appear: roughly 6,529 housing units for every covered ZIP code, 56,718 households to a county, 14 named communities in the grid. The balance between the generations reads 4.2 pre-1980 homes for every home built since 2000 — a single ratio that quietly predicts whether a metro's HVAC week leans toward renewal work in the old districts or first-generation upkeep in the new ones.
The New Orleans record in one line — median home age: 53 years · owner-occupied homes: 239,408 · renter-occupied homes: 157,621 · pre-1960 homes per covered ZIP code: 2,037 · heating-to-cooling degree-day ratio: 0.55 · average rainfall: 1,621 mm a year.
