Permits and inspections for AC replacement
A new air conditioner in Florida is not just a mechanical swap; it is a permitted job with an inspection at the end. Here is why that exists, what it actually checks, and why it is worth letting your contractor handle it.
Does a new AC system really need a permit in Florida?
Replacing a central air conditioner in Florida is a permitted job almost everywhere in the state, and South Florida is no exception. That surprises some homeowners, who assume a permit is only for additions or renovations that change a structure. An AC system involves electrical connections, refrigerant lines, and equipment tied to the building itself, which is exactly the kind of work municipalities require a permit and a final inspection for. Understanding why the process exists, and what it actually checks, makes it far less mysterious when your contractor mentions it.
Yes. A full system replacement — a new outdoor condenser and indoor coil, or a new air handler — is mechanical work covered by the Florida Building Code, and virtually every city and county in the state requires a permit for it, including throughout Broward County and southern Palm Beach County. A straightforward, like-for-like repair generally does not need one; a full replacement does.
Why it is treated differently from a repair
The line sits where the work does: repairing a failed part keeps the existing, already-approved installation in place, while a replacement involves new equipment, new electrical connections, and sometimes new refrigerant line work, all of which the code requires to be verified once installed.
The permit is not there to slow the job down; it is the record that the electrical and refrigerant work actually met code.
United A/C & RefrigerationWhat does the permit process actually check?
The inspection looks at the parts of the installation that matter for safety and code compliance, not the brand of equipment or how it performs. That typically includes the electrical disconnect and wiring at the outdoor unit, proper condensate drainage so the system cannot leak into the structure, correct refrigerant line work, and that the equipment is set and secured properly. In a hurricane-prone area, mounting and tie-down of the outdoor unit gets particular attention, since a poorly secured condenser is a genuine hazard once storm-force wind gets under it.
What it does not cover
The permit inspection is not a performance test; it does not verify how well the system cools, how quiet it runs, or how efficient it turns out to be over a season. That is a separate, ongoing responsibility of the installer and, later, of maintenance — the permit's job is narrower, and specifically about safety and code, not comfort.
Do Broward and Palm Beach counties handle permits the same way?
Not identically. Permitting in Florida is administered at the city or county level, so while the underlying building code is largely consistent statewide, the specific process — where to submit, how scheduling works, which inspections are required in what order — varies from one municipality to the next across Broward County and southern Palm Beach County. A contractor who works across both regularly knows the local variations rather than assuming one city's process applies everywhere.
Why that local knowledge matters
A permit filed incorrectly for a given jurisdiction, or an inspection scheduled out of the required order, can add delay to a job that should have been straightforward. This is largely invisible to a homeowner when it goes right, and frustrating when it does not.
Why does United pull the permit instead of leaving it to me?
Because the permit is tied to the license doing the work, and that is how accountability is supposed to function. A licensed contractor pulling the permit under their own license takes responsibility for the installation meeting code, start to finish, including the final inspection. A homeowner-pulled permit on a contractor-installed system muddies exactly that accountability, and some jurisdictions do not allow it for this kind of work regardless.
What that looks like in practice
In practice, it means scheduling the permit and the inspection is simply part of the replacement job, folded into the timeline rather than left as a separate task for the homeowner to track down after the equipment is already running.
What happens if a system was installed without a permit?
It happens, particularly with older equipment or work done by an unlicensed installer, and it can create problems later that have nothing to do with how well the system cools. An unpermitted installation can complicate a home sale, since a buyer's inspection or the closing process may flag it, and it can leave a homeowner without a documented record that the electrical and refrigerant work ever met code — much like a system whose warranty was never registered leaves coverage the homeowner assumed they had unconfirmed.
What to do about an older, unpermitted system
If you are not sure whether a past installation was permitted, it is worth finding out before it becomes a problem at resale rather than after. A licensed contractor can help you understand where things stand and what, if anything, needs to be addressed.
Why permitting leans hurricane-aware here
South Florida's building code carries wind-load and mounting requirements that show up directly in an AC permit inspection, because an outdoor condenser is exposed equipment sitting outside a home that has to withstand serious storm wind. Tie-down straps, pad anchoring, and secure electrical disconnects all get scrutiny that a milder-climate inspection would not apply in the same way. Flood-prone and low-lying pockets, particularly near canals and the intracoastal, also bring condensate drainage and equipment placement into sharper focus than they would elsewhere, since standing water around an outdoor unit after a heavy storm is a real, recurring concern in parts of Broward and southern Palm Beach. And in older, established neighborhoods where a system may have changed hands or been swapped by different companies over the decades, permit history is not always as clean as it should be, which is part of why confirming it matters more here than in a newer, better-documented home. None of this is exotic; it is simply the code responding to the actual conditions equipment has to survive in this part of the state, year after hurricane season.

Questions and answers
How long does the permit and inspection process take?
It varies by city, since each municipality schedules and processes permits on its own timeline. Your contractor should be able to give you a realistic sense of what to expect for your specific jurisdiction, based on how that city's process typically runs, rather than a single number that applies everywhere.
Can I pull my own permit to save money?
In some jurisdictions a homeowner can, but it is generally not advisable when a licensed contractor is doing the installation, because it separates the accountability for code compliance from the party actually doing the work. Several municipalities also restrict or disallow it for contractor-installed mechanical work specifically.
Does a permit apply to a ductless mini-split installation too?
Yes, generally. A ductless system still involves electrical connections and refrigerant line work covered by the mechanical code, so most jurisdictions require the same permit and inspection process as a central system replacement.
What happens if the inspector finds something wrong?
The inspector notes what needs to be corrected, and the contractor addresses it and schedules a re-inspection. This is a normal, built-in part of the process rather than a sign of a serious problem, and a licensed contractor handles the correction and follow-up without it becoming the homeowner's responsibility.
Does hurricane strapping fall under this inspection?
Yes. Securing the outdoor unit against wind, including proper tie-down and pad anchoring, is one of the specific items a South Florida mechanical inspection checks, given how exposed that equipment is to storm conditions.
Will I need a new permit for a like-for-like repair?
Generally no. Repairing or replacing a failed component within an existing, already-permitted system typically does not require a new permit. A full system replacement, involving new major equipment, is what triggers the process.
How we know this
This advice comes from what our technicians actually find on service calls in Broward County and southern Palm Beach — not from national HVAC copy. Salt-air corrosion on the barrier island, drain lines that block every wet season, and equipment running nine months a year are local realities, and they change the right answer.
Worth disclosing: we install Amana equipment, so we are not an independent reviewer. Where a brand or product is discussed we say what it is good and bad at, and we will tell you when the honest answer is to repair what you have or do nothing yet.
