Start here if you read nothing else: this page covers Chittenden County, Vermont — 537 square miles, 8 listed communities, a centroid south of the Burlington metro's centre. Its climate record, from BURLINGTON INTL AP, VT US, sets a heating pressure on its systems. TempReach USA publishes the homework and routes the call; an independent local HVAC technician serving the county does the work.
The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at BURLINGTON INTL AP, VT US, the station for the Burlington metro this county belongs to. An average year there brings 6,960 heating degree days, 656 cooling degree days, 37.53 inches of precipitation, 8.2 days at 90 degrees or above and 144.7 nights at or below freezing, around an average temperature of 47.6 degrees.
Heating pressure in Chittenden County can be counted in codes as well as in degree days. From 05401 through 05461 to 05495, the county's 18 ZIP codes divide 537 square miles of housing that one cold record — 6,960 heating degree days, 144.7 freezing nights, kept at BURLINGTON INTL AP, VT US — examines in a single night. The fault is usually an old one, an igniter or an exchanger at the end of its winters; the ground it is found on, code by code, is what makes the diary this county's.
The county's neighbours frame it as well: Franklin County, Grand Isle County are among the 2 counties on its neighbour list, and together they form the working ground around Chittenden County's own 537 square miles. A system near a shared border lives in both counties' weather at once, whichever page describes its home — the pages divide the map so the record can be read county by county, and the links between them keep the whole in view.
There is a scale fact hidden in Chittenden County's ZIP codes: 18 codes across 537 square miles works out to 29.8 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 south of the Burlington 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.
The counties around Chittenden County include Franklin County, Grand Isle County, and the whole group shares the Burlington metro's climate record from BURLINGTON INTL AP, VT US. What the neighbours do not share is this county's ground: 537 square miles, 18 ZIP codes, a centroid south of the Burlington 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.
The county's year divides by load. At one end, 8.2 days at 90 degrees or above pull the cooling season into its long peak; at the other, 144.7 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 47.6 degrees at BURLINGTON INTL AP, VT US is what those two ends average out to, and 37.53 inches of precipitation spread across the year decide how much of the cooling season is also a moisture season. Chittenden 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.
Chittenden County is a county of distinct communities rather than one continuous town: Burlington, South Burlington, Essex Junction and Winooski are among the 8 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 south of the Burlington metro's centre, so its communities meet the Burlington 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.
The housing behind Chittenden County's systems is the Burlington metro's housing, read at county scale. The largest single share of the metro's homes was built between 1980 and 1999 — 28.3% of the stock — with 49.8% of homes predating 1980 and 21.9% arriving since 2000, around a median build year of 1980. Inside the county those eras divide by community and by street, but the proportions set the diary: a stock weighted to between 1980 and 1999 produces the service patterns of that era's systems, ducts and insulation, in this county as across the metro.
Coverage, for Chittenden County, is a set of overlapping maps. The land map is 537 square miles. The address map is 18 ZIP codes and 8 listed communities. The service map is the Burlington metro, whose coverage the county sits inside — south of the Burlington metro's centre, roughly 17 miles from its centre. The weather map is one station's record, kept at BURLINGTON INTL AP, VT US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.
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.
