AC repair in Miami-Dade

Most Miami systems fail in a handful of predictable ways, and most of those are worth fixing. The job is telling a repair that buys years from one that buys weeks, and that call gets made at the unit, not on the phone.

Call dispatch or send the form; an independent local AC contractor contacts you to set the visit, diagnoses the system, and quotes the repair in writing before doing it.

Common repairs

• Capacitors and contactors: the outdoor unit hums or clicks but the compressor or fan will not start. The most common repair in the county, often done on the first visit.
• Condensate drain: clogged line, tripped float switch, water on the floor or in the ceiling below a condo air handler. Cleared and treated; a properly sloped line and a trap prevent the next one.
• Fan motors and blower motors: noisy, slow, or stopped. Replaced with matching parts; on older air handlers the blower is sometimes the whole decision on repair versus replace.
• Refrigerant leaks: leak search, repair of the joint or coil, evacuation, and recharge by an EPA-certified technician. Topping off without finding the leak is not a repair.
• Thermostats and controls: dead screens, wrong readings, systems that ignore the setting. Includes rewiring a smart thermostat that was installed without a common wire.
• Electrical: burnt wires at the disconnect, failed transformers, breakers that trip under load.

Repair or replace?

A capacitor on a six-year-old system is a repair. A compressor on a fourteen-year-old R-410A system is a replacement, almost every time, because the part alone approaches half the price of a new system that runs on the current refrigerant and carries a fresh warranty. Between those, the contractor should show you what they found, tell you what else is likely to go, and quote both when it is close.

Ask about the age of the system (the data plate on the condenser has the manufacture date), whether the coil or compressor has been replaced before, and whether the refrigerant is R-410A or the older R-22, which is no longer produced and expensive to find.

Warranties and parts

Many systems under ten years old still have a parts warranty if the original installer registered them. Have the model and serial number ready and ask the contractor to check; it can turn a large repair into a labor-only one. Labor on repairs is usually warranted by the contractor for a stated period; get it in writing.
