In brief: 3,808 square miles of New Mexico, a climate read from LAS CRUCES 20 N, NM US's normals, and a heating pressure as the county's dominant one — 3,593 heating degree days set against 1,526 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 Doña Ana County.
Read Doña Ana County's weather the way this page reads it: through the thirty-year normals kept at LAS CRUCES 20 N, NM US for the Las Cruces metro. Those normals give the county 1,526 cooling degree days and 3,593 heating degree days a year, 10.26 inches of precipitation, 96.4 days at 90 degrees or above, 116.4 nights at or below freezing, and an average temperature of 59.3 degrees — the fixed background every system in the county works against.
Heating pressure in Doña Ana County can be counted in codes as well as in degree days. From 87936 through 88011 to 88072, the county's 23 ZIP codes divide 3,808 square miles of housing that one cold record — 3,593 heating degree days, 116.4 freezing nights, kept at LAS CRUCES 20 N, NM US — examines in a single night. The fault is usually an old one, an igniter or an exchanger at the end of its winters; the ground it is found on, code by code, is what makes the diary this county's.
Distance is the county fact the climate table leaves out. Doña Ana County's centroid lies close to the centre of the Las Cruces metro, roughly 0 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 23 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.
The ZIP list is the county's working map. Doña Ana County carries 23 codes, running from 87936 through 88011 in the middle of the list to 88072 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.
The neighbour list for Doña Ana County is empty in the record, and the page treats that as a fact about position rather than a gap: this county sits at its own place in the Las Cruces metro — close to the centre of the Las Cruces metro, roughly 0 miles from the centre — without another covered county directly beside it on this site. Its heating and cooling story is therefore told from its own record alone: land, codes, communities and climate, with the metro page carrying the wider frame.
A year in Doña Ana County, 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 1,526 cooling degree days, the second as 3,593 heating degree days; 10.26 inches of precipitation fall across both, and the average temperature of 59.3 degrees is simply the figure the two workloads leave behind when they are averaged. The county's heating pressure is whichever workload the count puts first — and the maintenance year is arranged around that ordering.
Start the county at its named places: Las Cruces, Vado, University Park, San Ysidro head a list of 14 communities recorded in Doña Ana County. The list matters to heating and cooling because communities concentrate the housing — a street of homes built in one decade produces one kind of service diary, the next community's different decade produces another — and because the roads between the named places are part of the working day here. The county page's climate record is shared; the ground it lands on is divided among these names.
The housing behind Doña Ana County's systems is the Las Cruces metro's housing, read at county scale. The largest single share of the metro's homes was built between 1980 and 1999 — 35.3% of the stock — with 32.3% of homes predating 1980 and 32.3% arriving since 2000, around a median build year of 1990. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to between 1980 and 1999 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.
One way to hold Doña Ana County in mind is as the local layer of a wider dataset. Above it sits the Las Cruces metro, with its Census housing profile and its NOAA station at LAS CRUCES 20 N, NM US. At this level sit the county's own numbers — 3,808 square miles, 0 neighbouring counties, 23 ZIP codes, 14 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 Doña Ana County and the Las Cruces metro.
