St. Tammany Parish heating & cooling, in brief

St. Tammany Parish covers 845 square miles in Louisiana. Its climate is read from the normals recorded at SLIDELL AP, LA US — 1,612 heating degree days against 2,634 cooling degree days — and its dominant pressure is a humid one. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving the county.

The St. Tammany Parish climate record

The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at SLIDELL AP, LA US, the station for the Slidell metro this county belongs to. An average year there brings 1,612 heating degree days, 2,634 cooling degree days, 61.88 inches of precipitation, 79.9 days at 90 degrees or above and 23.5 nights at or below freezing, around an average temperature of 67.7 degrees.

Read St. Tammany 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 845 square miles, 79.9 hot days a year, with no dry season long enough for a neglected system to hide in.

One more county fact belongs in the record: position. St. Tammany Parish sits at 30.410022, -89.951962 on the map — the centroid of a county whose communities spread across 845 square miles of Louisiana. Position decides which end of the metro's weather arrives first and which of its service patterns a household here meets most; the rest of this page is that position, read through the climate record and the metro's data.

The ZIP list is the county's working map. St. Tammany Parish carries 16 codes, running from 70420 through 70452 in the middle of the list to 70471 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.

A county with no neighbours on its record is a simpler map: St. Tammany Parish, 845 square miles of Louisiana, sitting close to the centre of the Slidell metro and carrying the Slidell metro's coverage at its edge. Nothing about the work simplifies with the map — the county's housing still spans its building decades, its systems still answer the full degree-day record — but the page can keep its whole attention on one county's ground, which is what it does.

Consider what one year asks of a system in St. Tammany Parish: a cooling season measured at 2,634 degree days, a heating season at 1,612, 79.9 days of serious heat and 23.5 freezing nights, and 61.88 inches of precipitation working on every outdoor unit through all of it. No single figure is remarkable; the combination is the county's climate, and it is the combination a system has to survive for fifteen or twenty years. The service patterns described on this page are that arithmetic, playing out across 845 square miles of housing.

Communities and housing in St. Tammany Parish

Name the ground and the work follows: in St. Tammany Parish, the 12 listed communities — Slidell, Mandeville, Covington, Eden Isle among them — hold the county's homes, and the homes hold its heating and cooling systems. The largest places supply the steadiest run of calls; the smaller communities supply the long drives and the systems fitted when those places were built. Either way, the county's 845 square miles are not read as one housing stock on this page, because on the ground they are not one: they are these communities, in this order, with these names.

Census figures give St. Tammany Parish's heating and cooling its proportions. The metro it belongs to counts 112,414 housing units across 103,286 households, 78.8% of them owner-occupied, and the era mix runs 4.5% before 1960, 18.4% from 1960 to 1979, 37.4% from 1980 to 1999 and 39.7% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same St. Tammany Parish street, built forty years apart, can need entirely different conversations from the same technician.

One way to hold St. Tammany Parish in mind is as the local layer of a wider dataset. Above it sits the Slidell metro, with its Census housing profile and its NOAA station at SLIDELL AP, LA US. At this level sit the county's own numbers — 845 square miles, 0 neighbouring counties, 16 ZIP codes, 12 listed places — and below it, not published anywhere, sit the individual homes whose systems all of it describes. This page works at the middle level, where the data is still local enough to act on.

What does the weather record mean for HVAC systems in St. Tammany Parish, Louisiana?
More than homeowners usually expect. A system in St. Tammany Parish, Louisiana does not live in an average climate; it lives in the record kept at SLIDELL AP, LA US — an average temperature of 67.7 degrees, built from 79.9 hot days and 23.5 freezing nights. The heating plant answers one end of that record, the cooling plant the other, and the county's dominant pressure, described above, is simply the two ends weighed against each other.

A run from the county's code ledger, as recorded: 70437, 70445, 70447, 70448, 70452, 70457, 70458, 70460, 70461, 70463.
Why does humidity burden on homes and cooling systems lead the problem list connected to St. Tammany Parish, Louisiana?
The honest answer is the metro's answer, localised. St. Tammany Parish, Louisiana sits inside the Slidell metro, whose page ranks its problems from public data; the leader there, humidity burden on homes and cooling systems, leads here too. What the county adds is emphasis: a humid-profile county leans its share of the diary toward the season and the systems its climate record presses hardest, as the narrative above sets out. The county's own ZIP list includes this run: 70437, 70445, 70447, 70448, 70452, 70457, 70458, 70460, 70461, 70463. Entered under St. Tammany Parish, Louisiana's name, the place ledger runs, populations attached: Slidell 28,664; Mandeville 12,931; Covington 11,568; Eden Isle 7,753; Lacombe 6,883; Abita Springs 2,669; Pearl River 2,614; Madisonville 971; Folsom 722; Sun 491; Lewisburg 242; Rio 217. For the record, St. Tammany Parish, Louisiana covers 845.267 square miles, about 540,971 acres, its centre entered at 30.410022, -89.951962, close to the centre of the Slidell metro.
Before which peak should a St. Tammany Parish, Louisiana household book its HVAC maintenance?
There are two rushes and a long preparation between them in St. Tammany Parish, Louisiana. The degree days at SLIDELL AP, LA US — 1,612 heating against 2,634 cooling — set the rushes' relative size, and the county's position, close to the centre of the Slidell metro, sets how fully the Slidell metro's weather drives them. Households here who treat the quieter season as preparation for the taller one rarely meet either peak at its height. On the county's own record, one run of the ZIP ledger reads: 70437, 70445, 70447, 70448, 70452, 70457, 70458, 70460, 70461, 70463.
