In brief: 1,938 square miles of California, a climate read from MERCED 23 WSW, CA US's normals, and a heating pressure as the county's dominant one — 2,908 heating degree days set against 980 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 Merced County.
One record, one county: the normals at MERCED 23 WSW, CA US — 2,908 heating degree days, 980 cooling degree days, 10.45 inches of precipitation, an average temperature of 59.7 degrees — applied to Merced County's own 1,938 square miles and its 19 ZIP codes. The figures are the Merced metro's; the ground they are applied to, lying close to the centre of the Merced metro, is this county's alone, and this section reads the two together.
There is a housing arithmetic under Merced County's heating season. The metro it belongs to built its largest share of homes between 1980 and 1999 — 28.4% of the stock — with the next share since 2000 at 27.5%, around a median build year of 1984. Fitted into those eras, the county's furnaces and heat pumps meet 45.4 freezing nights at very different ages, and the heating diary divides accordingly: deep repair conversations in the older bands, first-replacement conversations in the newer ones.
Set the county inside its metro and the picture completes. Merced County answers to the Merced metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 14 communities, 19 ZIP codes, one county's worth of systems ageing under the record kept at MERCED 23 WSW, CA 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 Merced County is a small climate-and-housing district of its own. The county's 19 codes — 93620, 93635, 93665, 95301 among them — all read the same normals from MERCED 23 WSW, CA 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.
The neighbour list for Merced 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 Merced metro — close to the centre of the Merced 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 Merced 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 980 cooling degree days, the second as 2,908 heating degree days; 10.45 inches of precipitation fall across both, and the average temperature of 59.7 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.
The county's place list tells its own story. Merced (89,766 residents) is the largest of the 14 communities the record names for Merced County, with Los Banos (46,776 residents) behind it and Atwater and Livingston further down the list. A technician working this county works all of those places in a single week, and the systems change character with the address: the era a community was built in decides whether the call is about an ageing furnace, a condenser at the end of its summers, or ductwork that predates the equipment it now serves.
The growth figures deserve their own reading in Merced County. 27.5% of the Merced metro's homes were built since 2000 — the largest or near-largest band in many of its counties — and those homes are now old enough that their first systems are reaching replacement age together, subdivision by subdivision. Set against them, the 44.1% of the metro's stock that predates 1980 is deep into its second and third systems. One county, two replacement waves running at once, and a maintenance diary that has to serve both.
A reader who only had Merced County's identifying figures would already know its shape: a county of 1,938 square miles in California, 19 ZIP codes, 14 communities on the record, sitting close to the centre of the Merced metro. What the figures cannot say alone is how the ground feels to work — the drives between calls, the mix of decades in the housing, the season that runs taller — and that is what the rest of this page is for, section by section.
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 Merced County and the Merced metro.
