Oswego County in one paragraph: 952 square miles in New York, 22 ZIP codes, a heating climate pressure read from the normals at SYRACUSE HANCOCK INTL AP, NY US, and housing that answers 6,588 heating degree days against 619 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.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at SYRACUSE HANCOCK INTL AP, NY US, the primary metro's station, read here for Oswego County. The record's shape is 6,588 heating degree days set against 619 cooling degree days, 39.88 inches of precipitation in an average year, 10.2 days reaching 90 degrees or above and 132.5 nights at or below freezing, with an average temperature of 48.5 degrees across the year.
Heating writes this county's HVAC calendar. With 6,588 heating degree days against 619 cooling degree days in the normals recorded at SYRACUSE HANCOCK INTL AP, NY US, the systems across Oswego County earn their keep in the cold half of the year: furnaces and heat pumps cycling through 132.5 nights at or below freezing, when a breakdown stops being a comfort problem and becomes a household one. The pressure shows up as midwinter failures on the oldest equipment first, and a maintenance calendar that has to be kept in autumn — because by the time the cold arrives, the county's systems are already on stage.
Set the county inside its metro and the picture completes. Oswego County answers to the Syracuse metro's data — its housing profile, its problem ranking, its climate station — but the county is where that data touches ground: 2 communities, 22 ZIP codes, one county's worth of systems ageing under the record kept at SYRACUSE HANCOCK INTL AP, NY US. This page is that ground-level reading, kept separate from the metro page so the local detail is never averaged away.
Routing in Oswego County is written in five digits. The county's codes begin at 13028 and run to 13493, 22 in total, and between the first and the last sits the county's full spread of ground — 952 square miles from the metro-facing edge to the far side. A technician's week here is a tour of those codes, and the tour is also a tour of the county's building history, because each code's systems were largely fitted when that code's streets were built.
Neighbouring counties are the honest context for Oswego County's figures. Its 952 square miles sit inside a wider spread of county ground — Madison County, Onondaga County are among the 2 neighbours on its record — and its position northwest of the Syracuse metro's centre places it on its own side of that spread. A system near the county's edge may be closer to a neighbouring county's centre than to its own; the pages are organised by county because the data is, and the links between them carry the rest of the picture.
A service calendar for Oswego County can be written straight from its station record. Spring belongs to the cooling plant: 619 cooling degree days are coming, and the systems that will carry them are checked before the first of the 10.2 hot days arrives. Autumn belongs to the heating plant, ahead of 6,588 heating degree days and 132.5 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at SYRACUSE HANCOCK INTL AP, NY US does not change much year to year, which is what makes the calendar worth keeping.
A short place list shapes Oswego County's service pattern in a specific way. With Oswego, Fulton 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 952 square miles. Technicians routed here plan for distance as much as for faults: the drive between calls crosses the county's position northwest of the Syracuse metro's centre, and the systems at each end belong to different building decades even when the drive is short.
Census figures give Oswego County's heating and cooling its proportions. The metro it belongs to counts 297,056 housing units across 267,658 households, 68.3% of them owner-occupied, and the era mix runs 45.1% before 1960, 23.9% from 1960 to 1979, 19.5% from 1980 to 1999 and 11.5% since 2000. A county inside that metro inherits the mix in its own proportions — which is why two homes on the same Oswego County street, built forty years apart, can need entirely different conversations from the same technician.
A reader who only had Oswego County's identifying figures would already know its shape: a county of 952 square miles in New York, 22 ZIP codes, 2 communities on the record, sitting northwest of the Syracuse metro's centre. What the figures cannot say alone is how the ground feels to work — the drives between calls, the mix of decades in the housing, the season that runs taller — and that is what the rest of this page is for, section by section.
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 Oswego County and the Syracuse metro.
