Start here if you read nothing else: this page covers Hanover County, Virginia — 468 square miles, 1 listed communities, a centroid north of the Richmond metro's centre. Its climate record, from RICHMOND INTL AP, VA US, sets a heating pressure on its systems. TempReach USA publishes the homework and routes the call; an independent local HVAC technician serving the county does the work.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at RICHMOND INTL AP, VA US, the primary metro's station, read here for Hanover County. The record's shape is 3,736 heating degree days set against 1,560 cooling degree days, 45.5 inches of precipitation in an average year, 44.9 days reaching 90 degrees or above and 73.5 nights at or below freezing, with an average temperature of 59.0 degrees across the year.
Heating pressure in Hanover County can be counted in codes as well as in degree days. From 23005 through 23069 to 23192, the county's 9 ZIP codes divide 468 square miles of housing that one cold record — 3,736 heating degree days, 73.5 freezing nights, kept at RICHMOND INTL AP, VA 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.
Distance is the county fact the climate table leaves out. Hanover County's centroid lies north of the Richmond metro's centre, roughly 25 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 9 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
9 ZIP codes reach into Hanover County's 468 square miles, among them 23005, 23015, 23047, 23059 — an average of 52.0 square miles of county ground per code. The codes are more than a mailing grid here: they are how the county's service ground divides in practice, each code holding its own mix of housing eras, its own streets of systems ageing on their own schedules. A call in one code and a call in the next can be the same fault in different decades of house.
There are 16 counties on Hanover County's neighbour list, Dinwiddie County, Goochland County, Henrico 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.
There is a geography to Hanover County's seasons that the totals flatten. The county lies north of the Richmond metro's centre, roughly 25 miles from the centre the record is measured against, and its 468 square miles do not meet a hot week or a cold snap in one voice: the ground nearer the metro and the ground at the county's far edge live the same 44.9 hot days and 73.5 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
Read Hanover County through its record and two facts stand together: its named communities are Mechanicsville, and its land runs to 468 square miles. Between those facts sits the county's real housing — homes in the named places, homes along the roads the record does not name, all of them heating and cooling under the climate recorded at RICHMOND INTL AP, VA US. This page keeps both facts in view, because a county page that only described its named places would miss most of the county it is about.
The county's position frames its housing as well. Hanover County lies north of the Richmond metro's centre, roughly 25 miles out, and the metro's era mix — 29.6% built between 1980 and 1999, 25.8% since 2000, median year 1984 — reads at this distance with a county accent: the shares nearer the centre and the shares at the edge were platted in different decades of the metro's growth. Which band a given Hanover County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
The county is worth a page of its own because its facts do not reduce to its metro's. The Richmond metro supplies the climate station and the housing profile, but Hanover County supplies everything at ground level: 468 square miles, its own communities and codes, its own neighbours — Dinwiddie County, Goochland County, Henrico County among the 16 on its list — and its own position, north of the Richmond 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 Hanover County and the Richmond metro.
