The short version of this page: Livingston Parish runs to 648 square miles, its weather is the record kept at BATON ROUGE RYAN AP, LA US — 1,534 heating degree days, 2,818 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.
One record, one county: the normals at BATON ROUGE RYAN AP, LA US — 1,534 heating degree days, 2,818 cooling degree days, 61.94 inches of precipitation, an average temperature of 68.5 degrees — applied to Livingston Parish's own 648 square miles and its 10 ZIP codes. The figures are the Baton Rouge metro's; the ground they are applied to, lying east of the Baton Rouge metro's centre, is this county's alone, and this section reads the two together.
Livingston Parish is humid country, and its systems know it. 96.4 days a year at 90 degrees or more arrive carrying moisture, and every cooling system from to the county's edge spends its season wringing that moisture out — work measured in gallons of condensate, not just in degrees. The failures follow the load: clogged drains, overwhelmed coils, indoor air that never quite dries. Local technicians read the county that way: airflow and drainage checked as carefully as refrigerant, and maintenance kept ahead of the wettest weeks.
One more county fact belongs in the record: position. Livingston Parish sits at 30.440419, -90.727474 on the map — the centroid of a county whose communities spread across 648 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.
Routing in Livingston Parish is written in five digits. The county's codes begin at 70449 and run to 70786, 10 in total, and between the first and the last sits the county's full spread of ground — 648 square miles from the metro-facing edge to the far side. A technician's week here is a tour of those codes, and the tour is also a tour of the county's building history, because each code's systems were largely fitted when that code's streets were built.
Read the map around Livingston Parish and a working region appears: Iberville Parish, Pointe Coupee Parish, St. Helena Parish, West Baton Rouge Parish are the neighbouring names at the head of its list of 9, and together these counties form the ground a local technician actually covers. The county line decides which page describes a home; it does not decide the weather the home's system faces, the decade its street was built in, or the season its diary fills. Those are regional — and the region, on this site, is a set of county pages that link to one another, as the cards below do.
A year in Livingston Parish, counted the way a technician counts it, is not twelve months but two workloads and the weeks between them. The first workload is written as 2,818 cooling degree days, the second as 1,534 heating degree days; 61.94 inches of precipitation fall across both, and the average temperature of 68.5 degrees is simply the figure the two workloads leave behind when they are averaged. The county's humid pressure is whichever workload the count puts first — and the maintenance year is arranged around that ordering.
Some counties on this site are lists of towns; Livingston Parish is a territory. The record gives it 648 square miles, 9 neighbouring counties on the coverage map, and a position east of the Baton Rouge metro's centre — and its homes are distributed through that territory rather than gathered under place names the record can list. For heating and cooling the consequence is a diary of distance: longer drives between calls, systems of every era met one by one, and local knowledge that lives in roads and addresses instead of in town names.
Spread the metro's eras over Livingston Parish's own ground and the housing paragraph becomes a map: 648 square miles, 10 ZIP codes at 64.8 square miles per code, and a stock whose largest band was built since 2000 (35.0%), whose pre-1980 share runs to 36.1% and whose post-2000 share runs to 35.0%. 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.
There is a reason the coverage on this page is described county-first. Heating and cooling demand is generated house by house, and houses sit in counties: in Livingston Parish's case, across 648 square miles that hold 0 listed communities and 10 ZIP codes, east of the Baton Rouge metro's centre. The metro frame matters — the station, the housing eras, the problem ranking all come from it — but the county is where the frame touches the ground, and the ground is where the systems are.
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 Livingston Parish and the Baton Rouge metro.
