Gloucester County heating and cooling, county by county: 322 square miles of New Jersey lying southeast of the Philadelphia metro's centre, 26 ZIP codes, and a climate record read from PHILADELPHIA INTL AP, PA US. TempReach USA connects you with an independent local HVAC technician; this page sets out the county's own figures.

In brief: 322 square miles of New Jersey, a climate read from PHILADELPHIA INTL AP, PA US's normals, and a heating pressure as the county's dominant one — 4,510 heating degree days set against 1,358 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 Gloucester County.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at PHILADELPHIA INTL AP, PA US, the station for the Philadelphia metro this county belongs to. An average year there brings 4,510 heating degree days, 1,358 cooling degree days, 44.11 inches of precipitation, 29.7 days at 90 degrees or above and 77.3 nights at or below freezing, around an average temperature of 56.3 degrees.
Heating pressure in Gloucester County can be counted in codes as well as in degree days. From 08014 through 08074 to 08344, the county's 26 ZIP codes divide 322 square miles of housing that one cold record — 4,510 heating degree days, 77.3 freezing nights, kept at PHILADELPHIA INTL AP, PA 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.
The county's neighbours frame it as well: New Castle County, Philadelphia County, Salem County are among the 10 counties on its neighbour list, and together they form the working ground around Gloucester County's own 322 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.
The ZIP list is the county's working map. Gloucester County carries 26 codes, running from 08014 through 08074 in the middle of the list to 08344 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.
Gloucester County sits alongside New Castle County, Philadelphia County, Salem County in the Philadelphia area — 10 neighbouring counties share its coverage map in all, and the borders between them are lines on a map rather than changes in the weather. The same station record travels across those borders, the same housing decades appear on both sides, and a technician's ground here is really the cluster: this county and its neighbours, read together, with this page keeping Gloucester County's own share of the picture separate.
The county's year divides by load. At one end, 29.7 days at 90 degrees or above pull the cooling season into its long peak; at the other, 77.3 nights at or below freezing do the same for heating; between them sit the shoulder weeks when neither plant runs hard. An average temperature of 56.3 degrees at PHILADELPHIA INTL AP, PA US is what those two ends average out to, and 44.11 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Gloucester County's households plan around that division — service ahead of the taller peak, filters and checks in the shoulders — whether they name it or not.
Gloucester County's named places — Glassboro — anchor a county that is mostly ground between names: 322 square miles, 26 ZIP codes, and housing that follows the roads more than the towns. The wider metro it belongs to is anchored by Philadelphia (1,582,432 residents) and Camden, but this county's own diary is quieter and more spread out: individual systems in individual houses, ageing on the schedule of the decade each house was built, from the named communities outward.
Age is the county's second climate. The Philadelphia metro's median home was built in 1966, and 67.3% of its homes predate 1980 — in Gloucester County, that share is the older districts and the long-settled communities, where ductwork from an earlier equipment era still serves replacement systems. The newer share, 13.9% built since 2000, concentrates in the county's growth edges. The service diary divides along that line: deep equipment-and-duct conversations at the old end, first-replacement and control conversations at the new one.
One way to hold Gloucester County in mind is as the local layer of a wider dataset. Above it sits the Philadelphia metro, with its Census housing profile and its NOAA station at PHILADELPHIA INTL AP, PA US. At this level sit the county's own numbers — 322 square miles, 10 neighbouring counties, 26 ZIP codes, 1 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.
