In brief: 254 square miles of Maine, a climate read from PORTLAND INTL JETPORT, ME US's normals, and a heating pressure as the county's dominant one — 6,795 heating degree days set against 447 cooling degree days in an average year. TempReach USA does not do the work itself; it is a referral service, and one call connects you with an independent local HVAC technician serving Sagadahoc County.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at PORTLAND INTL JETPORT, ME US, the primary metro's station, read here for Sagadahoc County. The record's shape is 6,795 heating degree days set against 447 cooling degree days, 48.12 inches of precipitation in an average year, 5.1 days reaching 90 degrees or above and 144.1 nights at or below freezing, with an average temperature of 47.5 degrees across the year.
Divide Sagadahoc County's cold by its coverage and the heating diary sharpens: 8 ZIP codes over 254 square miles, 31.7 square miles per code on average, the codes running from 04008 to 04579. A furnace failure in the code nearest the metro reads differently from one at the county's far edge — not in the fault, which is the same worn igniter or tired blower, but in everything around it: the drive, the house's decade, the odds the system has already been replaced once. The cold itself, 6,795 heating degree days of it, is shared; the ground it is answered on is not.
Set the county inside its metro and the picture completes. Sagadahoc County answers to the Portland metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 2 communities, 8 ZIP codes, one county's worth of systems ageing under the record kept at PORTLAND INTL JETPORT, ME US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
Count the coverage from the codes upward: 04008, 04086 and 04287 are the first codes on Sagadahoc County's list of 8, spread across its 254 square miles in Maine. 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.
The counties around Sagadahoc County include Cumberland County, York County, and the whole group shares the Portland metro's climate record from PORTLAND INTL JETPORT, ME US. What the neighbours do not share is this county's ground: 254 square miles, 8 ZIP codes, a centroid northeast of the Portland metro's centre. Service patterns cross the county line freely — a cold week fills diaries on both sides of it — but the mix of housing and systems on each side is its own, which is why each county in the group carries its own page.
There is a geography to Sagadahoc County's seasons that the totals flatten. The county lies northeast of the Portland metro's centre, roughly 26 miles from the centre the record is measured against, and its 254 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 5.1 hot days and 144.1 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
The county record names Bath, Topsham among Sagadahoc County's communities — a short list, and an honest one: much of the county's housing sits outside its named places, along the roads and in the settlements between them, across 254 square miles of Maine. The heating and cooling diary follows that pattern. Calls cluster where the named communities cluster, then spread out along the county's ZIP codes, and the systems at the far ends of those drives were fitted in the decades their houses were built, community or no community.
Ownership writes part of the diary too. Across the Portland metro, 73.1% of households own their homes, and owner-occupiers and landlords keep different maintenance calendars — owners tending to plan replacements in the shoulder seasons, rented homes more often meeting their systems at the point of failure. Sagadahoc County shares that metro pattern across its 8 ZIP codes and its listed communities, and it shows in the timing of the calls as much as in their content: planned work where the owners live, urgent work where they do not.
One way to hold Sagadahoc County in mind is as the local layer of a wider dataset. Above it sits the Portland metro, with its Census housing profile and its NOAA station at PORTLAND INTL JETPORT, ME US. At this level sit the county's own numbers — 254 square miles, 2 neighbouring counties, 8 ZIP codes, 2 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.
