Lawrence County in one paragraph: 357 square miles in Pennsylvania, 16 ZIP codes, a heating climate pressure read from the normals at PITTSBURGH ALLEGHENY CO AP, PA US, and housing that answers 5,406 heating degree days against 826 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.
One record, one county: the normals at PITTSBURGH ALLEGHENY CO AP, PA US — 5,406 heating degree days, 826 cooling degree days, 41.34 inches of precipitation, an average temperature of 52.4 degrees — applied to Lawrence County's own 357 square miles and its 16 ZIP codes. The figures are the Pittsburgh metro's; the ground they are applied to, lying northwest of the Pittsburgh metro's centre, is this county's alone, and this section reads the two together.
There is a housing arithmetic under Lawrence County's heating season. The metro it belongs to built its largest share of homes before 1960 — 50.4% of the stock — with the next share between 1960 and 1979 at 23.1%, around a median build year of 1960. Fitted into those eras, the county's furnaces and heat pumps meet 105.8 freezing nights at very different ages, and the heating diary divides accordingly: deep repair conversations in the older bands, first-replacement conversations in the newer ones.
The county's ground shapes the work in one more way: 357 square miles is a lot of roofs for a service map to hold, and Lawrence County's homes divide between its listed communities — New Castle — 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.
A ZIP code in Lawrence County is a small climate-and-housing district of its own. The county's 16 codes — 16101, 16102, 16105, 16112 among them — all read the same normals from PITTSBURGH ALLEGHENY CO AP, PA US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.
There are 7 counties on Lawrence County's neighbour list, Allegheny County, Armstrong County, Beaver 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.
The county's year divides by load. At one end, 8.4 days at 90 degrees or above pull the cooling season into its long peak; at the other, 105.8 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 52.4 degrees at PITTSBURGH ALLEGHENY CO AP, PA US is what those two ends average out to, and 41.34 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Lawrence 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.
Read Lawrence County through its record and two facts stand together: its named communities are New Castle, and its land runs to 357 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 PITTSBURGH ALLEGHENY CO AP, PA 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.
Look at the second era as well as the first and Lawrence County's stock comes into focus. After the dominant band — homes built before 1960, 50.4% of the metro's total — the next share was built between 1960 and 1979, at 23.1%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.
One way to hold Lawrence County in mind is as the local layer of a wider dataset. Above it sits the Pittsburgh metro, with its Census housing profile and its NOAA station at PITTSBURGH ALLEGHENY CO AP, PA US. At this level sit the county's own numbers — 357 square miles, 7 neighbouring counties, 16 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.
