- 3. Submit through the Fort Lauderdale permit portal and pay the review fee.

Frequently asked questions
Do I need a permit to replace an AC unit?
Yes. A mechanical permit is required for a residential air conditioner changeout in every Florida jurisdiction, and the work must be inspected. Licensed HVAC contractors pull this permit as part of the job.
What size AC do I need in Florida?
A rough Florida rule of thumb is one ton of cooling per 500-600 square feet of conditioned space, but proper sizing uses a Manual J load calculation that accounts for insulation, window area, orientation and ceiling height. Oversized systems short-cycle and fail to remove humidity.
How long does an AC last in Florida?
Because systems run nearly year-round and coastal salt air accelerates corrosion, Florida air conditioners typically last 10-15 years versus 15-20 in cooler climates.
What this permit actually cost
