Union Parish heating and cooling, county by county: 877 square miles of Louisiana lying northwest of the Monroe metro's centre, 7 ZIP codes, and a climate record read from MONROE RGNL AP, LA US. TempReach USA connects you with an independent local HVAC technician; this page sets out the county's own figures.

In brief: 877 square miles of Louisiana, a climate read from MONROE RGNL AP, LA US's normals, and a humid pressure as the county's dominant one — 2,213 heating degree days set against 2,495 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 Union Parish.
Before the narrative, the numbers themselves, because everything after them is commentary: at MONROE RGNL AP, LA US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 96.7 days at 90 degrees or above, 32.7 nights at or below freezing, 55.1 inches of precipitation and degree-day totals of 2,213 heating against 2,495 cooling. Spread over 877 square miles, with the county's centroid northwest of the Monroe metro's centre and roughly 25 miles from the centre it is measured against, that record is Union Parish's working climate.
Union Parish is humid country, and its systems know it. 96.7 days a year at 90 degrees or more arrive carrying moisture, and every cooling system from Farmerville 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.
Distance is the county fact the climate table leaves out. Union Parish's centroid lies northwest of the Monroe metro's centre, roughly 25 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 7 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.
7 ZIP codes reach into Union Parish's 877 square miles, among them 71222, 71234, 71241, 71256 — an average of 125.3 square miles of county ground per code. The codes are more than a mailing grid here: they are how the county's service ground divides in practice, each code holding its own mix of housing eras, its own streets of systems ageing on their own schedules. A call in one code and a call in the next can be the same fault in different decades of house.
There are 3 counties on Union Parish's neighbour list, Morehouse Parish, Ouachita Parish, Richland 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.
A year in Union 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 2,495 cooling degree days, the second as 2,213 heating degree days; 55.1 inches of precipitation fall across both, and the average temperature of 65.7 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.
There is a practical reason this page names Union 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 3 places recorded here, from Farmerville through its remaining communities and beyond, each carry that clue in their streets. The metro data on the Monroe page describes the whole region; this list is where the description becomes local.
Look at the second era as well as the first and Union Parish's stock comes into focus. After the dominant band — homes built between 1960 and 1979, 31.0% of the metro's total — the next share was built between 1980 and 1999, at 29.0%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.
One way to hold Union Parish in mind is as the local layer of a wider dataset. Above it sits the Monroe metro, with its Census housing profile and its NOAA station at MONROE RGNL AP, LA US. At this level sit the county's own numbers — 877 square miles, 3 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 Union Parish and the Monroe metro.
