What happens on AC installation day in Florida?
A clear, step-by-step picture of what an AC replacement day actually looks like — from how to prepare your home to what the crew does, how permits and inspection fit in, and what you should have in hand when they leave.
Replacing an air conditioner is a big purchase, and most homeowners have never watched one happen. Not knowing what to expect on install day is a common source of anxiety: How long will it take? Do I need to be home? What about the permit? This guide walks through a typical Florida AC replacement day from start to finish, so there are no surprises — including how to prepare, what a licensed crew does step by step, and exactly what you should receive when the work is done.

Before install day.
By the time install day is scheduled, the important decisions are already made: the equipment is selected from your assessment, the scope is set (straight changeout, or duct/electrical work if the home needs it), and the permit is filed with the local building department.
There is very little you need to do, but a few things help the day go smoothly: clear a path to the indoor air handler (often a closet, garage, or attic) and the outdoor condenser, move vehicles so the crew can stage equipment, and secure pets away from open doors. Plan for the air conditioning to be off for several hours during the changeover — in summer, starting early helps beat the afternoon heat.
What the crew does during the install.
A typical Florida changeout follows the same sequence:
1. Protect the home — floor and surface protection along the work path. 2. Recover and remove — the old refrigerant is recovered per EPA rules, and the old condenser and air handler are removed. 3. Set the new equipment — the new outdoor condenser is placed on its pad or stand with proper clearances and hurricane tie-downs, and the new indoor air handler or coil is set. 4. Connect — refrigerant line set, electrical whip and disconnect, condensate drain with a safety float switch, and the thermostat. 5. Evacuate and charge — the system is pulled into a deep vacuum to remove moisture, then charged to the manufacturer's specification. 6. Start up and test — the crew powers the system, checks the temperature split and airflow, confirms the drain runs clear, and verifies the thermostat controls everything correctly.
In Florida, correct charge, airflow, and condensate handling are what determine whether the system controls humidity well — so a careful startup matters as much as the equipment itself.
Permits and inspection.
Florida requires a mechanical permit for AC replacement, and in many cities an electrical permit as well. The licensed contractor pulls the permit before the work and schedules the inspection after — this is part of the job, not something the homeowner files.
The inspection happens after installation, sometimes a few days later depending on the jurisdiction's schedule. A building inspector verifies the work meets code — including equipment placement, electrical, condensate safety, and (in High-Velocity Hurricane Zones like Miami-Dade and Broward) wind-load tie-downs. The permit and final inspection result become part of your closeout record, which matters for resale and for warranty claims.
After the install.
When the crew leaves, the system should be running and cooling. Before they go, walk through a quick closeout: confirm the thermostat works, ask where the condensate drain and float switch are, and get the model and serial numbers of the installed equipment.
You should receive (now or shortly after): the permit record, the manufacturer warranty registration details, and any workmanship/labor warranty paperwork. Registering the equipment with the manufacturer on time is important — it can affect the length of the parts warranty. Over the first few days, the home should hold both temperature and humidity steadily; if it feels cold but clammy, that's worth raising while everything is fresh.
How NewHVACDeals runs install day.
Because the equipment and scope are settled through the online assessment before install day, there are no driveway renegotiations and no surprise add-ons. A DBPR-licensed crew handles the work, pulls the permit, and schedules the inspection as standard scope.
The assessment-driven approach means the system was sized with a Manual J and the ductwork reviewed beforehand, so the crew installs against a known plan. Six written guarantees back the work, and the closeout documentation — permit, warranty, equipment details — is provided so you have a complete record of what was installed and that it passed inspection.
Frequently asked questions
- How long does AC installation take in Florida?
- A standard changeout — new equipment using existing, reusable ductwork — is often completed in a single day. Jobs that include duct modifications, electrical panel work, or difficult attic/roof access can run longer, which the assessment identifies in advance.
- Do I need to be home during AC installation?
- Usually someone should be home at the start to give the crew access and confirm the plan, and at the end for the walkthrough. You don't need to watch the entire process, but being present for startup lets you ask questions while the crew is there.
- How should I prepare for AC installation day?
- Clear a path to both the indoor air handler and the outdoor condenser, move vehicles so the crew can stage equipment, secure pets, and plan for the AC to be off for part of the day. In summer, an early start helps avoid the afternoon heat.
- When does the permit inspection happen?
- After the installation. The licensed contractor schedules it with the local building department, and an inspector verifies the work meets code — including condensate safety and, in hurricane zones, tie-downs. The result becomes part of your closeout record.
