Essex County covers 126 square miles in New Jersey. Its climate is read from the normals recorded at TETERBORO AP, NJ US — 4,735 heating degree days against 1,255 cooling degree days — and its dominant pressure is a heating one. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving the county.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at TETERBORO AP, NJ US, the station for the New York metro this county belongs to. An average year there brings 4,735 heating degree days, 1,255 cooling degree days, 46.29 inches of precipitation, 28.9 days at 90 degrees or above and 89.0 nights at or below freezing, around an average temperature of 55.4 degrees.
Read the climate record and the county's pressure names itself. Heating degree days outnumber cooling degree days at TETERBORO AP, NJ US, and the lived version of that statistic is a housing stock whose furnaces and heat pumps run the long season while its cooling takes the short one. Across Essex County's 126 square miles — from Newark to the county's edge communities — the pattern repeats: systems sized for the cold, maintained for the cold, and replaced, when their time comes, with the cold in mind first.
Distance is the county fact the climate table leaves out. Essex County's centroid lies close to the centre of the New York metro, roughly 8 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 31 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.
Routing in Essex County is written in five digits. The county's codes begin at 07003 and run to 07114, 31 in total, and between the first and the last sits the county's full spread of ground — 126 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.
Position first: Essex County lies close to the centre of the New York metro, roughly 8 miles from the metro's centre as the map measures it, with Bergen County, Bronx County, Hudson County among the counties around it. Neighbourhood at county scale matters to heating and cooling because systems do not respect the border — the same subdivisions' building decades continue across it, the same cold snaps and heat waves examine both sides in the same night — while each county's page, this one included, keeps the local figures distinct.
A year in Essex 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 1,255 cooling degree days, the second as 4,735 heating degree days; 46.29 inches of precipitation fall across both, and the average temperature of 55.4 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.
A short place list shapes Essex County's service pattern in a specific way. With Newark, East Orange the named communities on its record, the county's calls divide between those places and the unincorporated ground around them — and the ground is the larger share of its 126 square miles. Technicians routed here plan for distance as much as for faults: the drive between calls crosses the county's position close to the centre of the New York metro, and the systems at each end belong to different building decades even when the drive is short.
Census figures give Essex County's heating and cooling its proportions. The metro it belongs to counts 7,991,914 housing units across 7,362,500 households, 51.5% of them owner-occupied, and the era mix runs 50.9% before 1960, 22.9% from 1960 to 1979, 13.7% from 1980 to 1999 and 12.4% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Essex County street, built forty years apart, can need entirely different conversations from the same technician.
One way to hold Essex County in mind is as the local layer of a wider dataset. Above it sits the New York metro, with its Census housing profile and its NOAA station at TETERBORO AP, NJ US. At this level sit the county's own numbers — 126 square miles, 21 neighbouring counties, 31 ZIP codes, 2 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.
