AC Permits and Licensing in Miami-Dade and Broward: What Homeowners Should Know

Yes, Replacing an AC Requires a Permit

This surprises a lot of homeowners. Replacing an existing air conditioning system is not treated as a like-for-like swap — in Miami-Dade, Broward and Palm Beach it is permitted mechanical work, and the permit is pulled by the licensed contractor, not by you.

The requirement exists because an AC installation touches several safety-relevant systems at once: electrical connections and disconnect, refrigerant lines, condensate drainage, structural attachment of the outdoor unit, and in South Florida, hurricane tie-downs. An inspection verifies those were done to code.

Repairs are different. Routine repairs — a capacitor, a contactor, a motor, a refrigerant service — generally do not require a permit. The line is roughly at replacing major equipment or altering the system's electrical or duct configuration.

Why This Matters More Than It Sounds

Manufacturer warranty. Carrier and every other major manufacturer condition their warranty on installation by a licensed contractor to code. An unpermitted installation gives the manufacturer grounds to deny a claim on expensive components years later, when it hurts most.

Homeowners insurance. If an unpermitted installation contributes to a loss — water damage from a badly run condensate line, an electrical fire, a condenser that came loose in a storm — you are in a much weaker position on the claim.

Selling the house. Unpermitted work shows up in title and permit searches. Buyers' attorneys ask about open or missing permits, and resolving it retroactively is slower and more expensive than doing it correctly the first time. In some cases the county requires the work to be opened up for inspection.

Hurricane tie-downs. This is the South Florida specific. Code requires outdoor condensers to be anchored against hurricane-force wind. It is exactly the kind of detail an uninspected installation skips, and exactly the kind that matters in September.

What the Inspection Actually Checks

• Electrical disconnect present, correctly rated and properly located
• Wire gauge and breaker sizing matched to the equipment
• Condensate drainage routed correctly, with the required secondary protection
• Outdoor unit anchored to its pad per wind-load requirements
• Equipment matched — indoor and outdoor components rated to work together
• Clearances around the unit for airflow and service access

None of these are exotic. They are exactly the corners a very low bid has to cut in order to be a very low bid.

How to Verify a Contractor

Florida licenses HVAC contractors at the state level, and you can verify a license yourself through the Florida Department of Business and Professional Regulation. Miami-Dade and Broward also maintain local contractor registration.

Ask for and confirm:

• The license number, and check it is active and in the correct category for the work.
• Liability insurance and workers' compensation. Ask for a certificate of insurance. If an uninsured worker is injured on your property, that exposure can land on you.
• Who is pulling the permit. If a contractor asks you to pull an owner-builder permit for work they are performing, that is a serious red flag — it shifts liability to you and often indicates a licensing problem.
• A written scope of work. Permits, tie-downs, disconnect and drainage should appear in the quote, not be discovered later as extras.

The "No Permit, Cheaper Price" Offer

You will encounter it. The savings are real in the short term and the exposure is real for as long as you own the house. It also tends to correlate with other shortcuts you cannot see — undersized wiring, missing secondary drain protection, no load calculation.

If a quote is dramatically below others, the honest question is what is not in it. Frequently the answer is the permit, the tie-downs, and the ductwork.

What a Correct Process Looks Like

The contractor evaluates the home and performs a load calculation. The quote states the equipment, the scope and that permitting is included. The contractor pulls the permit under their license before work begins. The installation is completed, the county inspects it, and the permit is closed. You receive documentation, and the manufacturer warranty is registered in your name.

That closed permit is a record that protects you for as long as you own the home.
