Chapter 489How Florida licenses air conditioning contractors
Air conditioning contracting is licensed at state level by the Construction Industry Licensing Board within DBPR, under Chapter 489, Part I, Florida Statutes. A state certification covers the City of Oviedo and unincorporated Seminole County alike — there is no separate city licence to hold.
Fla. Stat. 489.105(3) defines the classes by scope, not by brand or company size: a Class A contractor is unlimited in the execution of contracts for central air conditioning, refrigeration, heating and ventilating systems; a Class B contractor is limited to 25 tons of cooling and 500,000 Btu of heating in any one system, which comfortably covers residential changeouts; a Class C contractor is service only, and applies to people who held a valid Class C licence as of 1 October 1988.
Fla. Stat. 489.119(5)(b) requires the certification number to appear in each offer of services, business proposal, bid, contract or advertisement, regardless of medium. That includes a website. Check our license, and any other contractor's, on DBPR's Verify a Licensee search before anyone touches your equipment.
Where the housing numbers come from
Every parcel count, median build year, band share and pool count on this site is from the Seminole County Property Appraiser CAMA extract, Parcels.csv dated 5 September 2026 — residential improved parcels, DOR codes 01xx and 04xx, tax districts V1, V2 and V5. Medians are nearest-rank, so each one is a year that actually exists in the data rather than an average. 223 distinct subdivisions are in the extract and 255 parcels carry no subdivision name at all.
Neighbourhood build windows
The build windows on the service areas page are each subdivision's own HOA or listing-source wording, credited beside them. They are not the same measurement as the appraiser's medians, which is why the two are kept on separate pages.
