In brief: 58 square miles of Massachusetts, a climate read from BEVERLY MUNI AP, MA US's normals, and a heating pressure as the county's dominant one — 6,103 heating degree days set against 611 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 Suffolk County.
The station for this county's metro is BEVERLY MUNI AP, MA US, and its NOAA 1991-2020 normals are the source of every figure in this section. Precipitation averages 44.89 inches a year; the temperature record averages 49.8 degrees, built from 10.0 days at 90 or above and 126.1 nights at or below freezing; the workload totals 6,103 heating degree days and 611 cooling degree days. Suffolk County is read through that record throughout this page.
There is a second heating pressure in Suffolk County that the degree days only imply: repetition across distance. A cold snap does not visit one street here; it visits all 35 of the county's ZIP codes in the same night, from the communities nearest the metro's centre to the edge of its 58 square miles, and every ageing system in that ground is examined by the same low temperature at the same hour. That simultaneity — many systems, one weather, a county's worth of roads between the calls — is what makes the cold weeks in a heating-profile county feel different from the same weeks in a city.
One more county fact belongs in the record: position. Suffolk County sits at 42.338551, -71.018253 on the map — the centroid of a county whose communities spread across 58 square miles of Massachusetts. Position decides which end of the metro's weather arrives first and which of its service patterns a household here meets most; the rest of this page is that position, read through the climate record and the metro's data.
A ZIP code in Suffolk County is a small climate-and-housing district of its own. The county's 35 codes — 02108, 02109, 02110, 02111 among them — all read the same normals from BEVERLY MUNI AP, MA 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.
Suffolk County sits alongside Rockingham County, Strafford County, Essex County in the Boston area — 6 neighbouring counties share its coverage map in all, and the borders between them are lines on a map rather than changes in the weather. The same station record travels across those borders, the same housing decades appear on both sides, and a technician's ground here is really the cluster: this county and its neighbours, read together, with this page keeping Suffolk County's own share of the picture separate.
There is a geography to Suffolk County's seasons that the totals flatten. The county lies south of the Boston metro's centre, roughly 15 miles from the centre the record is measured against, and its 58 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 10.0 hot days and 126.1 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
A short place list shapes Suffolk County's service pattern in a specific way. With Boston, Cambridge 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 58 square miles. Technicians routed here plan for distance as much as for faults: the drive between calls crosses the county's position south of the Boston metro's centre, and the systems at each end belong to different building decades even when the drive is short.
Census figures give Suffolk County's heating and cooling its proportions. The metro it belongs to counts 2,046,121 housing units across 1,925,474 households, 61.8% of them owner-occupied, and the era mix runs 46.7% before 1960, 20.3% from 1960 to 1979, 17.6% from 1980 to 1999 and 15.3% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Suffolk County street, built forty years apart, can need entirely different conversations from the same technician.
Put the county's coverage facts in one place and they read like this: 58 square miles of land in Massachusetts, 2 listed communities, 35 ZIP codes, 6 neighbouring counties on the record, and a place inside the Boston metro coverage. No single figure describes the county; the set of them does, and it is the set this page is organised around, from the climate record above to the community and ZIP lists below.
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 Suffolk County and the Boston metro.
