What changed for AC here
A quote in 2026 looks different from one in 2023. This is why, and what the county requires on any replacement.
The refrigerant switched in 2025
Manufacturers stopped building R-410A systems on January 1, 2025. New systems use R-454B or R-32 depending on the manufacturer; both are mildly flammable refrigerants that needed redesigned equipment and leak sensors, which is why replacement quotes jumped. Your existing R-410A system is still legal to run and service.
Efficiency floor and rebates
Since 2023 a new split system in the Southeast has to be at least SEER2 14.3. FPL offers an instant rebate on higher-efficiency systems installed by an FPL-approved contractor; ask whether the system you are quoted qualifies.
Every change-out needs a permit
Miami-Dade requires a mechanical permit for any AC replacement, equipment with a Miami-Dade Notice of Acceptance, and the condenser tied down with brackets rated for hurricane winds. Homeowners cannot pull this permit themselves; the licensed contractor does.
What fails on Miami systems
The calls we hear most, and what is usually behind them.
- Blowing warm on the hottest afternoon of the year: a failed capacitor or contactor, the most common and cheapest repair there is.
- Water on the floor by the air handler: a clogged condensate drain line, which also trips the float switch and shuts the system off.
- Ice on the copper lines: low refrigerant from a leak, or airflow choked by a dirty filter or coil. Turn it off and let it thaw before the visit.
- Runs all day and never catches up: a coil that needs cleaning, a refrigerant charge that is off, or a system that is simply at the end of its life.
- One room never cools: duct leaks in the attic, a crushed flex duct, or a return that is too small for the house.
- Condenser rusting through near the coast: salt air; coated coils and regular rinsing on the next unit.

Questions people ask
My AC just stopped. What should I do right now?
Check the breaker and the thermostat batteries, make sure the filter is not clogged solid, and look for water at the air handler or ice on the copper lines. If there is ice, turn the system off so it can thaw. Then call and say what the system is doing.
Should I repair my R-410A system or replace it?
R-410A is still legal to service, and a good repair on a system under ten years old is usually the right call. Past twelve to fifteen years in Miami, or with a failed compressor or a leaking coil, replacement usually wins. The contractor should show you what they found and quote both when it is close.
Does a replacement need a permit in Miami-Dade?
Yes, every change-out. The contractor pulls a mechanical permit, installs equipment with a Miami-Dade Notice of Acceptance, ties down the condenser to hurricane code, and the inspector closes it out. Be wary of anyone who offers to skip it; it will surface when you sell or file an insurance claim.
What does it cost?
What drives the number: the size of the system (tonnage), the SEER2 rating, the refrigerant type, where the air handler sits, whether ductwork or electrical needs work, tie-downs, and the permit. The contractor gives you a written quote after seeing the system.
Do you help in Spanish?
Yes. Call in English or Spanish; every page is in both.
