In brief: 781 square miles of Louisiana, a climate read from NEW ORLEANS ALVIN CALLENDER FL, LA US's normals, and a humid pressure as the county's dominant one — 1,425 heating degree days set against 2,615 cooling degree days in an average year. TempReach USA does not do the work itself; it is a referral service, and one call connects you with an independent local HVAC technician serving Plaquemines Parish.
Climate on this page is not a national average wearing a county's name. It is the specific record at NEW ORLEANS ALVIN CALLENDER FL, LA US: 68.2 degrees as the average temperature, 63.8 inches of precipitation, 64.4 hot days and 10.8 freezing nights in the average year, 1,425 heating degree days against 2,615 cooling degree days. Plaquemines Parish — 781 square miles, 8 ZIP codes, 0 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
Read Plaquemines Parish's humidity through its calendar and a pattern emerges: the wettest weeks and the hottest weeks are neighbours, so the condensate drain, the coil and the blower are all examined by peak load at the same time, across every community in the county at once. That overlap is the humid profile's real pressure — not heat alone, not moisture alone, but both arriving together over 781 square miles, 64.4 hot days a year, with no dry season long enough for a neglected system to hide in.
Distance is the county fact the climate table leaves out. Plaquemines Parish's centroid lies southeast of the New Orleans metro's centre, roughly 48 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 8 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
The ZIP list is the county's working map. Plaquemines Parish carries 8 codes, running from 70037 through 70050 in the middle of the list to 70091 at its end, and every code on it is a small housing census of its own — the building decades, the system generations, the duct materials of its streets. Heating and cooling work routed by those codes meets the county in slices, and the slices differ more than the county's shared climate record would suggest.
Position first: Plaquemines Parish lies southeast of the New Orleans metro's centre, roughly 48 miles from the metro's centre as the map measures it, with Orleans Parish, St. Bernard Parish, St. Charles Parish among the counties around it. Neighbourhood at county scale matters to heating and cooling because systems do not respect the border — the same subdivisions' building decades continue across it, the same cold snaps and heat waves examine both sides in the same night — while each county's page, this one included, keeps the local figures distinct.
There is a geography to Plaquemines Parish's seasons that the totals flatten. The county lies southeast of the New Orleans metro's centre, roughly 48 miles from the centre the record is measured against, and its 781 square miles do not meet a hot week or a cold snap in one voice: the ground nearer the metro and the ground at the county's far edge live the same 64.4 hot days and 10.8 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
The county record for Plaquemines Parish carries no separate place list — its communities are held in the record through its ZIP codes and its 781 square miles of ground instead, southeast of the New Orleans metro's centre. That shape suits the county's service diary: calls here follow addresses and roads rather than town centres, spread across the county's full extent, and the systems they reach were fitted in the decades their individual houses were built. The New Orleans metro's larger communities — New Orleans, Metairie, Kenner — anchor the region around it; this county's own ground is the quieter share of the map.
Ownership writes part of the diary too. Across the New Orleans metro, 60.3% of households own their homes, and owner-occupiers and landlords keep different maintenance calendars — owners tending to plan replacements in the shoulder seasons, rented homes more often meeting their systems at the point of failure. Plaquemines Parish shares that metro pattern across its 8 ZIP codes and its listed communities, and it shows in the timing of the calls as much as in their content: planned work where the owners live, urgent work where they do not.
Put the county's coverage facts in one place and they read like this: 781 square miles of land in Louisiana, 0 listed communities, 8 ZIP codes, 6 neighbouring counties on the record, and a place inside the New Orleans metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
City pages carry the metro-wide homework — housing eras, the problem ranking, services in depth. This county sits inside their coverage.
TempReach USA is not an HVAC company. We employ no heating or cooling technicians, we run no service trucks, and we do not carry out HVAC work of any kind. This website and its call center exist for one purpose: to connect homeowners with independent local heating and cooling professionals who serve their area. When you call the number on this site, your call is routed to such a professional. From that point, everything about the job belongs to that professional and to you: the assessment, the work itself, the scheduling, what you are charged, and the terms of any agreement you reach. The professional who takes your job is solely responsible for it. The technician who arrives at your home runs their own business; they are not an employee, agent or subcontractor of TempReach USA. Our part is the information on these pages — assembled from Census Bureau housing data and NOAA climate records for each metro — and the routing of your call. We state this plainly on purpose: you should know exactly who you are hiring before anyone picks up a wrench or a gauge.
One call connects you with an independent local heating and cooling professional serving Plaquemines Parish and the New Orleans metro.
