The short version of this page: Imperial County runs to 4,176 square miles, its weather is the record kept at IMPERIAL CO AP, CA US — 966 heating degree days, 4,162 cooling degree days — and its systems live under a cooling 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.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at IMPERIAL CO AP, CA US, the primary metro's station, read here for Imperial County. The record's shape is 966 heating degree days set against 4,162 cooling degree days, 2.38 inches of precipitation in an average year, 181.1 days reaching 90 degrees or above and 4.1 nights at or below freezing, with an average temperature of 73.7 degrees across the year.
Imperial County is cooling country by the numbers: 4,162 cooling degree days a year, 181.1 days of serious heat, and homes spread over 4,176 square miles all asking their systems the same question at the same hour of the same July afternoon. The heating half of the equipment matters — 966 heating degree days is not nothing — but it is the cooling load that decides which systems fail, and when. Local technicians read the county that way: spring tune-ups, honest conversations about ageing condensers, and vans stocked for the hot weeks.
One more county fact belongs in the record: position. Imperial County sits at 33.040814, -115.3554 on the map — the centroid of a county whose communities spread across 4,176 square miles of California. 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.
Count the coverage from the codes upward: 92222, 92227 and 92231 are the first codes on Imperial County's list of 15, spread across its 4,176 square miles in California. No two of those codes hold quite the same housing — one may be a settled community's streets, the next newer subdivisions, the next open county ground — so the same climate record produces a different run of calls inside each. The full list is printed on this page; the diary is written code by code.
The neighbour list for Imperial 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 El Centro metro — close to the centre of the El Centro 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.
There is a geography to Imperial County's seasons that the totals flatten. The county lies close to the centre of the El Centro metro, roughly 0 miles from the centre the record is measured against, and its 4,176 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 181.1 hot days and 4.1 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
The county's place list tells its own story. El Centro (44,186 residents) is the largest of the 14 communities the record names for Imperial County, with Calexico (38,476 residents) behind it and Brawley and Imperial 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.
Census figures give Imperial County's heating and cooling its proportions. The metro it belongs to counts 57,511 housing units across 48,844 households, 56.8% of them owner-occupied, and the era mix runs 15.4% before 1960, 23.7% from 1960 to 1979, 31.1% from 1980 to 1999 and 29.8% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Imperial County street, built forty years apart, can need entirely different conversations from the same technician.
Coverage, for Imperial County, is a set of overlapping maps. The land map is 4,176 square miles. The address map is 15 ZIP codes and 14 listed communities. The service map is the El Centro metro, whose coverage the county sits inside — close to the centre of the El Centro metro, roughly 0 miles from its centre. The weather map is one station's record, kept at IMPERIAL CO AP, CA US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.
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 Imperial County and the El Centro metro.
