Where in Seminole County can I book HVAC?

Permits
Does HVAC work need a permit in Seminole County?
Seminole County lists replacing a condenser, an air handler or a package unit among the work that requires a permit.
In unincorporated Seminole County, permits come from the county's Building Division. Inside Altamonte Springs and Lake Mary, the city's own building department issues them, so the street address decides which office a HVAC job goes through.

Urgency
When is HVAC an emergency in Seminole County?
The request form treats a unit with no cooling or no heat at all as an emergency. There is no emergency response target yet: HQ calls back to say whether 1Stop can cover it, and a target is published once an approved vendor covers HVAC in the county.
A system that runs but struggles, with a resident affected and the unit still habitable, is urgent: same day. A planned replacement is scheduled work, booked to a date.
Licensing
What license does a HVAC vendor need in Seminole County?
HVAC work takes a Florida air-conditioning license (Class A, B or C) or a mechanical contractor license, issued through DBPR.
For a property in Seminole County, that means a certified license, or a registration that covers the property's city or county. 1Stop holds the license on file before it dispatches HVAC work.
