Lehigh County Heating & Cooling Services

The Lehigh County climate record

Before the narrative, the numbers themselves, because everything after them is commentary: at ALLENTOWN INTL AP, PA US, the station whose NOAA 1991-2020 normals this county is read through, an average year holds 18.2 days at 90 degrees or above, 118.1 nights at or below freezing, 47.36 inches of precipitation and degree-day totals of 5,293 heating against 981 cooling. Spread over 345 square miles, with the county's centroid southwest of the Allentown metro's centre and roughly 15 miles from the centre it is measured against, that record is Lehigh County's working climate.

Lehigh County is heating country by the numbers: 5,293 heating degree days a year, 118.1 freezing nights, and homes spread over 345 square miles all asking their systems the same question on the same January night. The cooling half of the equipment matters — 981 cooling degree days is not nothing — but it is the heating load that decides which systems fail, and when. Local technicians read the county that way: autumn tune-ups, honest conversations about ageing furnaces and heat exchangers, and vans stocked for the cold weeks.

Set the county inside its metro and the picture completes. Lehigh County answers to the Allentown metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 7 communities, 28 ZIP codes, one county's worth of systems ageing under the record kept at ALLENTOWN INTL AP, PA US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.

There is a scale fact hidden in Lehigh County's ZIP codes: 28 codes across 345 square miles works out to 12.3 square miles per code, which makes a service call here a matter of ground as well as of systems. The codes on the metro-facing side of the county — the county sits southwest of the Allentown metro's centre — and the codes at its far edge hold different ground, but both ends ask the same climate questions of their heating and cooling, at different distances.

Read the map around Lehigh County and a working region appears: Carbon County, Northampton County, Warren County are the neighbouring names at the head of its list of 3, and together these counties form the ground a local technician actually covers. The county line decides which page describes a home; it does not decide the weather the home's system faces, the decade its street was built in, or the season its diary fills. Those are regional — and the region, on this site, is a set of county pages that link to one another, as the cards below do.

There is a geography to Lehigh County's seasons that the totals flatten. The county lies southwest of the Allentown metro's centre, roughly 15 miles from the centre the record is measured against, and its 345 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 18.2 hot days and 118.1 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.

Communities and housing in Lehigh County

Lehigh County is a county of distinct communities rather than one continuous town: Allentown, Bethlehem, Fullerton and Emmaus are among the 7 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 southwest of the Allentown metro's centre, so its communities meet the Allentown 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 Lehigh County's heating and cooling its proportions. The metro it belongs to counts 360,133 housing units across 336,977 households, 69.5% of them owner-occupied, and the era mix runs 41.2% before 1960, 21.2% from 1960 to 1979, 21.1% from 1980 to 1999 and 16.5% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Lehigh 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 Allentown metro supplies the climate station and the housing profile, but Lehigh County supplies everything at ground level: 345 square miles, its own communities and codes, its own neighbours — Carbon County, Northampton County, Warren County among the 3 on its list — and its own position, southwest of the Allentown metro's centre. The metro page and this page link to each other because neither half of that picture stands well without the other.

Our role in Lehigh 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.
