When your AC quits on a Florida afternoon in Port St. Lucie, you need help fast. First Aid Air Conditioning offers same-day AC repair across town on every major brand and model, including Carrier, Trane, Lennox, Rheem, Goodman, American Standard, Daikin, Mitsubishi, and others. Our technicians arrive ready to diagnose the real issue, explain what's happening in plain English, and give you written options before any work starts. Family-owned, Florida-licensed, and on Port St. Lucie repair calls every week.
We work across all of Port St. Lucie: Tradition, Saint Lucie West, PGA Village, The Reserve, Lake Charles, Castle Pines, River Park, Tesoro, the Indian River Estates area, the older neighborhoods east of US-1, the Floresta corridor, and the newer master-planned communities on the west side of town. We're on jobs in these neighborhoods every week and often have a tech already nearby when you call.
Capacitor failure: the number one reason an AC system won't start in Florida summer. The capacitor stores the burst of electricity needed to start the compressor and fan motor. In Port St. Lucie heat the capacitor cooks gradually until its microfarad rating drops below spec, and one afternoon the system won't kick on. A new capacitor is a low-hundreds repair and most are done in under an hour on site.
Low refrigerant from a slow leak: shows up as an AC that runs constantly but doesn't cool. We use electronic leak detection to find the leak source, repair the fitting, pressure-test the lines, and recharge to manufacturer spec. Common leak points are the service valve fittings on the outdoor unit, the connections at the indoor air handler, and aging flare fittings on the line set.
Frozen evaporator coil: a low refrigerant charge or a restricted airflow problem (dirty filter, blocked return) can cause the coil to ice over. The system keeps running but blows warm air. We shut the system down to let the coil thaw, diagnose the underlying cause, and repair the source so it doesn't ice up again.
Blower motor failure: the indoor blower fan motor can burn out after years of running through Florida summers. Symptoms range from a humming sound with no airflow to a system that runs intermittently. Most blower motors are stocked parts and the swap takes an hour or two.
Control board failure after a summer storm: power surges from lightning strikes and downed lines fry control boards. Symptoms are usually the system not responding to thermostat commands or cycling on and off unexpectedly. Replacement boards are typically in stock at the parts house.
Condenser fan motor failure: the outdoor fan that pulls air across the condenser coil can give out from heat stress. Symptoms include the compressor running but the outdoor fan stopped (which damages the compressor if left running). We replace the motor and verify proper airflow.
Drain line clog: a clogged condensate drain causes water to back up into the air handler closet, sometimes triggering the safety shutoff switch and stopping the system. We clear the line, flush the trap, and treat the line to prevent algae regrowth.
Calls received before noon typically get a same-day appointment during peak season. Calls after noon get a next-morning slot if all techs are booked. We dispatch the closest available tech to keep response time as short as possible.
When the tech arrives, the first step is a full diagnostic. We don't guess. We measure microfarad ratings on the capacitor, refrigerant pressures on the line set, amp draws on the motors, and resistance readings on the contactor. The diagnostic determines the actual cause of the failure, not just the symptom. Then we present written options with pricing, and you decide whether to authorize the repair.
The diagnostic visit carries a small service call fee that's credited toward the cost of any repair you authorize. Emergency and after-hours calls may include an additional dispatch fee, which we disclose up front before sending a technician.
Capacitors (multiple ratings), contactors (common voltages), hard-start kits, common control boards, condensate float switches, blower motor capacitors, refrigerant for the most common types (R-410A, R-454B), basic line set fittings, and tools for leak detection and pressure testing. Most repairs finish on the same visit because we have the parts on board.
On a system that's under 8 years old, repair almost always makes sense. On a system that's 12 years or older with a major failure (failed compressor, multiple refrigerant leaks, or repeated component failures), we'll have an honest conversation about replacement. The 50 percent rule is a useful heuristic: if the repair cost is more than 50 percent of replacement cost, replacement is usually the better call.
