Lafayette Parish in one paragraph: 269 square miles in Louisiana, 11 ZIP codes, a humid climate pressure read from the normals at LAFAYETTE RGNL AP, LA US, and housing that answers 1,377 heating degree days against 3,007 cooling degree days a year. TempReach USA is a referral service, not an HVAC company — one call connects you with an independent local HVAC technician serving this county.
Climate on this page is not a national average wearing a county's name. It is the specific record at LAFAYETTE RGNL AP, LA US: 69.4 degrees as the average temperature, 62.81 inches of precipitation, 90.7 hot days and 11.3 freezing nights in the average year, 1,377 heating degree days against 3,007 cooling degree days. Lafayette Parish — 269 square miles, 11 ZIP codes, 6 listed communities — lives inside that record, and its heating and cooling systems are sized, serviced and replaced inside it too.
Read Lafayette 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 269 square miles, 90.7 hot days a year, with no dry season long enough for a neglected system to hide in.
Set the county inside its metro and the picture completes. Lafayette Parish answers to the Lafayette metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 6 communities, 11 ZIP codes, one county's worth of systems ageing under the record kept at LAFAYETTE RGNL AP, LA US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
A ZIP code in Lafayette Parish is a small climate-and-housing district of its own. The county's 11 codes — 70501, 70503, 70506, 70507 among them — all read the same normals from LAFAYETTE RGNL AP, LA US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.
There are 3 counties on Lafayette Parish's neighbour list, Acadia Parish, St. Martin Parish, Vermilion Parish among them, and the list is a reminder that a county page is a slice of a continuous map. The slice is worth keeping separate: this county's land area, its ZIP codes and its communities are its own, and its heating and cooling pressure — the humid profile described above — lands on its own housing. But the slice only makes full sense beside its neighbours, whose pages are linked from this one for exactly that reason.
Extremes, not averages, fill Lafayette Parish's emergency diary, and the record names them precisely: 90.7 days a year at 90 degrees or above, 11.3 nights at or below freezing. Between those figures sits the ordinary year — an average of 69.4 degrees, 62.81 inches of rain — in which systems mostly age quietly. The two ends are when ageing becomes failure, which is why the county's dominant humid pressure, the taller of its two peaks, sets the rhythm of its maintenance year as well.
There is a practical reason this page names Lafayette Parish's communities one by one. A heating or cooling system belongs to a house, a house belongs to a community, and the community's building decade is the strongest single clue to what the system will need — the 6 places recorded here, from Lafayette through Carencro and beyond, each carry that clue in their streets. The metro data on the Lafayette page describes the whole region; this list is where the description becomes local.
The housing behind Lafayette Parish's systems is the Lafayette metro's housing, read at county scale. The largest single share of the metro's homes was built since 2000 — 32.9% of the stock — with 40.1% of homes predating 1980 and 32.9% arriving since 2000, around a median build year of 1987. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to since 2000 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.
Put the county's coverage facts in one place and they read like this: 269 square miles of land in Louisiana, 6 listed communities, 11 ZIP codes, 3 neighbouring counties on the record, and a place inside the Lafayette 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.
