Seminole County covers 309 square miles in Florida. Its climate is read from the normals recorded at ORLANDO EXECUTIVE AP, FL US — 468 heating degree days against 3,694 cooling degree days — and its dominant pressure is a humid one. TempReach USA is a referral service, not an HVAC company: one call connects you with an independent local HVAC technician serving the county.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at ORLANDO EXECUTIVE AP, FL US, the primary metro's station, read here for Seminole County. The record's shape is 468 heating degree days set against 3,694 cooling degree days, 51.47 inches of precipitation in an average year, 110.8 days reaching 90 degrees or above and 1.2 nights at or below freezing, with an average temperature of 73.8 degrees across the year.
Read the climate record and the county's pressure names itself. Precipitation of 51.47 inches a year at ORLANDO EXECUTIVE AP, FL US, layered over 3,694 cooling degree days, means Seminole County's heating and cooling is moisture management wearing a temperature costume. Homes across its 309 square miles ask their systems to dry the air as much as to cool it — and the systems that answer well are the ones sized, charged and drained with that double duty in mind.
The county's ground shapes the work in one more way: 309 square miles is a lot of roofs for a service map to hold, and Seminole County's homes divide between its listed communities — Sanford, Altamonte Springs — and the roads between them. A technician routed here is working a county, not a street: the drive between calls is part of the diary, and the systems at each end of it were fitted in the decades those communities were built.
Count the coverage from the codes upward: 32701, 32707 and 32708 are the first codes on Seminole County's list of 14, spread across its 309 square miles in Florida. 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 Seminole County include Lake County, Orange County, Osceola County, and the whole group shares the Orlando metro's climate record from ORLANDO EXECUTIVE AP, FL US. What the neighbours do not share is this county's ground: 309 square miles, 14 ZIP codes, a centroid northeast of the Orlando 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 Seminole County's seasons that the totals flatten. The county lies northeast of the Orlando metro's centre, roughly 17 miles from the centre the record is measured against, and its 309 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 110.8 hot days and 1.2 freezing nights through different housing, fitted in different decades. One station record, one county, two ends of every season.
A short place list shapes Seminole County's service pattern in a specific way. With Sanford, Altamonte Springs 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 309 square miles. Technicians routed here plan for distance as much as for faults: the drive between calls crosses the county's position northeast of the Orlando metro's centre, and the systems at each end belong to different building decades even when the drive is short.
Spread the metro's eras over Seminole County's own ground and the housing paragraph becomes a map: 309 square miles, 14 ZIP codes at 22.1 square miles per code, and a stock whose largest band was built since 2000 (38.9%), whose pre-1980 share runs to 24.7% and whose post-2000 share runs to 38.9%. The percentages are the metro's; the streets they land on are this county's, and a technician driving from one end of the county to the other drives through the bands in sequence.
One way to hold Seminole County in mind is as the local layer of a wider dataset. Above it sits the Orlando metro, with its Census housing profile and its NOAA station at ORLANDO EXECUTIVE AP, FL US. At this level sit the county's own numbers — 309 square miles, 3 neighbouring counties, 14 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.
One call connects you with an independent local heating and cooling professional serving Seminole County and the Orlando metro.
