Wake County covers 835 square miles in North Carolina. Its climate is read from the normals recorded at RALEIGH DURHAM INTL AP, NC US — 3,153 heating degree days against 1,804 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.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at RALEIGH DURHAM INTL AP, NC US, the primary metro's station, read here for Wake County. The record's shape is 3,153 heating degree days set against 1,804 cooling degree days, 46.07 inches of precipitation in an average year, 52.4 days reaching 90 degrees or above and 64.7 nights at or below freezing, with an average temperature of 61.2 degrees across the year.
Heating pressure in Wake County can be counted in codes as well as in degree days. From 27502 through 27603 to 27697, the county's 32 ZIP codes divide 835 square miles of housing that one cold record — 3,153 heating degree days, 64.7 freezing nights, kept at RALEIGH DURHAM INTL AP, NC 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 ground shapes the work in one more way: 835 square miles is a lot of roofs for a service map to hold, and Wake County's homes divide between its listed communities — Raleigh, Cary, Apex, Wake Forest, Holly Springs, Garner — and the roads between them. A technician routed here is working a county, not a street: the drive between calls is part of the diary, and the systems at each end of it were fitted in the decades those communities were built.
The ZIP list is the county's working map. Wake County carries 32 codes, running from 27502 through 27603 in the middle of the list to 27697 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.
There are 2 counties on Wake County's neighbour list, Franklin County, Johnston County among them, and the list is a reminder that a county page is a slice of a continuous map. The slice is worth keeping separate: this county's land area, its ZIP codes and its communities are its own, and its heating and cooling pressure — the heating profile described above — lands on its own housing. But the slice only makes full sense beside its neighbours, whose pages are linked from this one for exactly that reason.
A service calendar for Wake County can be written straight from its station record. Spring belongs to the cooling plant: 1,804 cooling degree days are coming, and the systems that will carry them are checked before the first of the 52.4 hot days arrives. Autumn belongs to the heating plant, ahead of 3,153 heating degree days and 64.7 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at RALEIGH DURHAM INTL AP, NC US does not change much year to year, which is what makes the calendar worth keeping.
Wake County is a county of distinct communities rather than one continuous town: Raleigh, Cary, Apex and Wake Forest are among the 11 places on its record, each with its own building era and its own stock of systems. Position plays its part as well — the county sits west of the Raleigh metro's centre, so its communities meet the Raleigh metro's weather at slightly different distances from the centre — but it is the place list that a service diary follows, name by name, through the year.
Census figures give Wake County's heating and cooling its proportions. The metro it belongs to counts 601,103 housing units across 555,371 households, 67.0% of them owner-occupied, and the era mix runs 6.7% before 1960, 13.0% from 1960 to 1979, 33.0% from 1980 to 1999 and 47.3% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Wake County street, built forty years apart, can need entirely different conversations from the same technician.
The county is worth a page of its own because its facts do not reduce to its metro's. The Raleigh metro supplies the climate station and the housing profile, but Wake County supplies everything at ground level: 835 square miles, its own communities and codes, its own neighbours — Franklin County, Johnston County among the 2 on its list — and its own position, west of the Raleigh metro's centre. The metro page and this page link to each other because neither half of that picture stands well without the other.
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 Wake County and the Raleigh metro.
