The short version of this page: Jefferson Davis Parish runs to 652 square miles, its weather is the record kept at LAKE CHARLES, LA US — 1,315 heating degree days, 3,063 cooling degree days — and its systems live under a humid pressure. One call to TempReach USA, a referral service rather than an HVAC company, connects you with an independent local HVAC technician serving the county.
The station for this county's metro is LAKE CHARLES, LA US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 59.75 inches a year; the temperature record averages 69.7 degrees, built from 88.5 days at 90 or above and 10.9 nights at or below freezing; the workload totals 1,315 heating degree days and 3,063 cooling degree days. Jefferson Davis Parish is read through that record throughout this page.
Humidity in Jefferson Davis Parish also divides by code. The county's 7 ZIP codes — 70532, 70546, 70549, 70581 at the head of the list — spread 652 square miles of housing under the same wet record: 59.75 inches of precipitation a year and 3,063 cooling degree days of load, read at LAKE CHARLES, LA US. Drains, coils and blowers meet that record in every code, but the housing they serve was fitted decade by decade, so the moisture diary is written code by code rather than county-wide at once.
The county's ground shapes the work in one more way: 652 square miles is a lot of roofs for a service map to hold, and Jefferson Davis Parish's homes divide between its listed communities — Jennings, Welsh, Elton — and the roads between them. A technician routed here is working a county, not a street: the drive between calls is part of the diary, and the systems at each end of it were fitted in the decades those communities were built.
There is a scale fact hidden in Jefferson Davis Parish's ZIP codes: 7 codes across 652 square miles works out to 93.1 square miles per code, which makes a service call here a matter of ground as well as of systems. The codes on the metro-facing side of the county — the county sits northeast of the Lake Charles metro's centre — and the codes at its far edge hold different ground, but both ends ask the same climate questions of their heating and cooling, at different distances.
Jefferson Davis Parish sits alongside Calcasieu Parish, Cameron Parish in the Lake Charles area — 2 neighbouring counties share its coverage map in all, and the borders between them are lines on a map rather than changes in the weather. The same station record travels across those borders, the same housing decades appear on both sides, and a technician's ground here is really the cluster: this county and its neighbours, read together, with this page keeping Jefferson Davis Parish's own share of the picture separate.
There is a geography to Jefferson Davis Parish's seasons that the totals flatten. The county lies northeast of the Lake Charles metro's centre, roughly 20 miles from the centre the record is measured against, and its 652 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 88.5 hot days and 10.9 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Jefferson Davis Parish is a county of distinct communities rather than one continuous town: Jennings, Welsh, Elton and its remaining communities are among the 3 places on its record, each with its own building era and its own stock of systems. Position plays its part as well — the county sits northeast of the Lake Charles metro's centre, so its communities meet the Lake Charles metro's weather at slightly different distances from the centre — but it is the place list that a service diary follows, name by name, through the year.
Spread the metro's eras over Jefferson Davis Parish's own ground and the housing paragraph becomes a map: 652 square miles, 7 ZIP codes at 93.1 square miles per code, and a stock whose largest band was built since 2000 (34.5%), whose pre-1980 share runs to 42.1% and whose post-2000 share runs to 34.5%. The percentages are the metro's; the streets they land on are this county's, and a technician driving from one end of the county to the other drives through the bands in sequence.
One way to hold Jefferson Davis Parish in mind is as the local layer of a wider dataset. Above it sits the Lake Charles metro, with its Census housing profile and its NOAA station at LAKE CHARLES, LA US. At this level sit the county's own numbers — 652 square miles, 2 neighbouring counties, 7 ZIP codes, 3 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.
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 Jefferson Davis Parish and the Lake Charles metro.
