Start here if you read nothing else: this page covers Madison County, Mississippi — 714 square miles, 3 listed communities, a centroid north of the Jackson metro's centre. Its climate record, from JACKSON INTL AP, MS US, sets a humid pressure on its systems. TempReach USA publishes the homework and routes the call; an independent local HVAC technician serving the county does the work.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at JACKSON INTL AP, MS US, the primary metro's station, read here for Madison County. The record's shape is 2,222 heating degree days set against 2,402 cooling degree days, 57.35 inches of precipitation in an average year, 84.7 days reaching 90 degrees or above and 39.6 nights at or below freezing, with an average temperature of 65.4 degrees across the year.
Position sharpens Madison County's moisture problem. The county lies north of the Jackson metro's centre, roughly 16 miles from the metro's centre, and the air that reaches its far edge has crossed the whole Jackson metro before it arrives — carrying the season's humidity into 714 square miles of homes whose systems must wring it out again, through 84.7 hot days a year. Neighbouring ground — Copiah County, Hinds County, Holmes County are among the counties around it — reads the same record; the wringing, house by house, is local.
Distance is the county fact the climate table leaves out. Madison County's centroid lies north of the Jackson metro's centre, roughly 16 miles from the centre it is measured against, and that distance is travelled on every call routed here — out through the metro's nearer counties and into this one's 7 ZIP codes. Local knowledge in a county like this is partly a map held in the head: which roads, which communities, which end of the county a call is coming from.
There is a scale fact hidden in Madison County's ZIP codes: 7 codes across 714 square miles works out to 102.0 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 north of the Jackson 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.
Neighbouring counties are the honest context for Madison County's figures. Its 714 square miles sit inside a wider spread of county ground — Copiah County, Hinds County, Holmes County are among the 7 neighbours on its record — and its position north of the Jackson 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.
Extremes, not averages, fill Madison County's emergency diary, and the record names them precisely: 84.7 days a year at 90 degrees or above, 39.6 nights at or below freezing. Between those figures sits the ordinary year — an average of 65.4 degrees, 57.35 inches of rain — in which systems mostly age quietly. The two ends are when ageing becomes failure, which is why the county's dominant humid pressure, the taller of its two peaks, sets the rhythm of its maintenance year as well.
Madison County is a county of distinct communities rather than one continuous town: Madison, Ridgeland, Canton and its remaining communities are among the 3 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 north of the Jackson metro's centre, so its communities meet the Jackson 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.
Look at the second era as well as the first and Madison County's stock comes into focus. After the dominant band — homes built between 1980 and 1999, 29.3% of the metro's total — the next share was built between 1960 and 1979, at 27.9%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.
A reader who only had Madison County's identifying figures would already know its shape: a county of 714 square miles in Mississippi, 7 ZIP codes, 3 communities on the record, sitting north of the Jackson 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 Madison County and the Jackson metro.
