Alexandria City in one paragraph: 15 square miles in Virginia, 6 ZIP codes, a heating climate pressure read from the normals at WASHINGTON DC DULLES AP, VA US, and housing that answers 4,604 heating degree days against 1,233 cooling degree days a year. TempReach USA is a referral service, not an HVAC company — one call connects you with an independent local HVAC technician serving this county.
Before the narrative, the numbers themselves, because everything after them is commentary: at WASHINGTON DC DULLES AP, VA US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 32.7 days at 90 degrees or above, 101.7 nights at or below freezing, 43.24 inches of precipitation and degree-day totals of 4,604 heating against 1,233 cooling. Spread over 15 square miles, with the county's centroid east of the Washington metro's centre and roughly 21 miles from the centre it is measured against, that record is Alexandria City's working climate.
Read the climate record and the county's pressure names itself. Heating degree days outnumber cooling degree days at WASHINGTON DC DULLES AP, VA 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 Alexandria City's 15 square miles — from Alexandria 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.
The county's ground shapes the work in one more way: 15 square miles is a lot of roofs for a service map to hold, and Alexandria City's homes divide between its listed communities — Alexandria — 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: 22301, 22302 and 22304 are the first codes on Alexandria City's list of 6, spread across its 15 square miles in Virginia. 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 22 counties on Alexandria City's neighbour list, Jefferson County, Loudoun County, Manassas City 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 Alexandria City can be written straight from its station record. Spring belongs to the cooling plant: 1,233 cooling degree days are coming, and the systems that will carry them are checked before the first of the 32.7 hot days arrives. Autumn belongs to the heating plant, ahead of 4,604 heating degree days and 101.7 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at WASHINGTON DC DULLES AP, VA US does not change much year to year, which is what makes the calendar worth keeping.
A short place list shapes Alexandria City's service pattern in a specific way. With Alexandria 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 15 square miles. Technicians routed here plan for distance as much as for faults: the drive between calls crosses the county's position east of the Washington metro's centre, and the systems at each end belong to different building decades even when the drive is short.
Spread the metro's eras over Alexandria City's own ground and the housing paragraph becomes a map: 15 square miles, 6 ZIP codes at 2.5 square miles per code, and a stock whose largest band was built between 1980 and 1999 (28.1%), whose pre-1980 share runs to 46.0% and whose post-2000 share runs to 25.9%. 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.
One way to hold Alexandria City in mind is as the local layer of a wider dataset. Above it sits the Washington metro, with its Census housing profile and its NOAA station at WASHINGTON DC DULLES AP, VA US. At this level sit the county's own numbers — 15 square miles, 22 neighbouring counties, 6 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.
One call connects you with an independent local heating and cooling professional serving Alexandria City and the Washington metro.
