The short version of this page: Sussex County runs to 518 square miles, its weather is the record kept at TETERBORO AP, NJ US — 4,735 heating degree days, 1,255 cooling degree days — and its systems live under a heating 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.
One record, one county: the normals at TETERBORO AP, NJ US — 4,735 heating degree days, 1,255 cooling degree days, 46.29 inches of precipitation, an average temperature of 55.4 degrees — applied to Sussex County's own 518 square miles and its 19 ZIP codes. The figures are the New York metro's; the ground they are applied to, lying northwest of the New York metro's centre, is this county's alone, and this section reads the two together.
There is a housing arithmetic under Sussex County's heating season. The metro it belongs to built its largest share of homes before 1960 — 50.9% of the stock — with the next share between 1960 and 1979 at 22.9%, around a median build year of 1959. Fitted into those eras, the county's furnaces and heat pumps meet 89.0 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.
The county's neighbours frame it as well: Bergen County, Bronx County, Essex County are among the 21 counties on its neighbour list, and together they form the working ground around Sussex County's own 518 square miles. A system near a shared border lives in both counties' weather at once, whichever page describes its home — the pages divide the map so the record can be read county by county, and the links between them keep the whole in view.
A ZIP code in Sussex County is a small climate-and-housing district of its own. The county's 19 codes — 07416, 07418, 07419, 07422 among them — all read the same normals from TETERBORO AP, NJ 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 counties around Sussex County include Bergen County, Bronx County, Essex County, and the whole group shares the New York metro's climate record from TETERBORO AP, NJ US. What the neighbours do not share is this county's ground: 518 square miles, 19 ZIP codes, a centroid northwest of the New York metro's centre. Service patterns cross the county line freely — a cold week fills diaries on both sides of it — but the mix of housing and systems on each side is its own, which is why each county in the group carries its own page.
A service calendar for Sussex County can be written straight from its station record. Spring belongs to the cooling plant: 1,255 cooling degree days are coming, and the systems that will carry them are checked before the first of the 28.9 hot days arrives. Autumn belongs to the heating plant, ahead of 4,735 heating degree days and 89.0 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at TETERBORO AP, NJ US does not change much year to year, which is what makes the calendar worth keeping.
Some counties on this site are lists of towns; Sussex County is a territory. The record gives it 518 square miles, 21 neighbouring counties on the coverage map, and a position northwest of the New York metro's centre — and its homes are distributed through that territory rather than gathered under place names the record can list. For heating and cooling the consequence is a diary of distance: longer drives between calls, systems of every era met one by one, and local knowledge that lives in roads and addresses instead of in town names.
The housing behind Sussex County's systems is the New York metro's housing, read at county scale. The largest single share of the metro's homes was built before 1960 — 50.9% of the stock — with 73.8% of homes predating 1980 and 12.4% arriving since 2000, around a median build year of 1959. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to before 1960 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.
Put the county's coverage facts in one place and they read like this: 518 square miles of land in New Jersey, 0 listed communities, 19 ZIP codes, 21 neighbouring counties on the record, and a place inside the New York metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
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 Sussex County and the New York metro.
