Chatham County Heating & Cooling Services

The Chatham County climate record

Every climate number on this page comes from one record: the NOAA 1991-2020 normals at SAVANNAH INTL AP, GA US, the primary metro's station, read here for Chatham County. The record's shape is 1,675 heating degree days set against 2,596 cooling degree days, 48.12 inches of precipitation in an average year, 80.5 days reaching 90 degrees or above and 21.4 nights at or below freezing, with an average temperature of 67.4 degrees across the year.

Humidity in Chatham County also divides by code. The county's 15 ZIP codes — 31302, 31322, 31328, 31401 at the head of the list — spread 433 square miles of housing under the same wet record: 48.12 inches of precipitation a year and 2,596 cooling degree days of load, read at SAVANNAH INTL AP, GA US. Drains, coils and blowers meet that record in every code, but the housing they serve was fitted decade by decade, so the moisture diary is written code by code rather than county-wide at once.

The county's ground shapes the work in one more way: 433 square miles is a lot of roofs for a service map to hold, and Chatham County's homes divide between its listed communities — Savannah, Pooler, Wilmington Island, Port Wentworth, Georgetown, Garden City — 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.

Count the coverage from the codes upward: 31302, 31322 and 31328 are the first codes on Chatham County's list of 15, spread across its 433 square miles in Georgia. 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.

There are 2 counties on Chatham County's neighbour list, Bryan County, Effingham 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 humid 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 Chatham County can be written straight from its station record. Spring belongs to the cooling plant: 2,596 cooling degree days are coming, and the systems that will carry them are checked before the first of the 80.5 hot days arrives. Autumn belongs to the heating plant, ahead of 1,675 heating degree days and 21.4 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at SAVANNAH INTL AP, GA US does not change much year to year, which is what makes the calendar worth keeping.

Communities and housing in Chatham County

Chatham County is a county of distinct communities rather than one continuous town: Savannah, Pooler, Wilmington Island and Port Wentworth 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 southeast of the Savannah metro's centre, so its communities meet the Savannah 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.

Spread the metro's eras over Chatham County's own ground and the housing paragraph becomes a map: 433 square miles, 15 ZIP codes at 28.8 square miles per code, and a stock whose largest band was built since 2000 (37.4%), whose pre-1980 share runs to 36.8% and whose post-2000 share runs to 37.4%. The percentages are the metro's; the streets they land on are this county's, and a technician driving from one end of the county to the other drives through the bands in sequence.

Coverage, for Chatham County, is a set of overlapping maps. The land map is 433 square miles. The address map is 15 ZIP codes and 11 listed communities. The service map is the Savannah metro, whose coverage the county sits inside — southeast of the Savannah metro's centre, roughly 15 miles from its centre. The weather map is one station's record, kept at SAVANNAH INTL AP, GA US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.

Our role in Chatham County, stated plainly

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.
