Our AC repair process is built on measurement. We check the thermostat, filter, airflow, electrical components, refrigerant charge, temperature split, and drainage, then explain what failed, why it failed, and what it costs to fix — in writing, before any work begins. If the failure is part of a bigger pattern (chronic low charge, corroded coils, undersized ducts), you'll hear that too, so you can weigh repair against replacement with real numbers.
Signs your AC needs repair
- Warm air from the vents while the outdoor unit runs
- Water dripping from the air handler or staining the ceiling
- Ice on the copper refrigerant line or the indoor coil
- Loud grinding, buzzing, or rattling at startup or shutdown
- Burning or electrical odors from vents or the outdoor unit
- Breaker trips when the system kicks on
- Thermostat reads 78°F but the room feels like 84°F
- Utility bills climbing without a change in settings
What affects your price
These factors shape your final price. Published local benchmark ranges appear in the page copy where they're relevant — and you'll get every charge in writing before work begins.
- Failed component: capacitor, contactor, motor, board, or compressor
- Refrigerant type — R-22 repairs cost substantially more than R-410A
- Leak search and repair scope before any recharge
- Attic or closet access in Florida heat
- Severity of salt corrosion on coils and connections
- Same-day, after-hours, weekend, or holiday timing

- Corrosion inspection of outdoor coil, cabinet, and electrical connections
- Written line-item estimate before any repair begins
- Repair photos and readings documented for your records
How we diagnose a no-cooling call
Every repair starts with the basics that actually matter in a Stuart attic: a clean filter, an open evaporator coil, a condensate drain that isn't backing up, and airflow that matches the equipment. Then we move to electrical — capacitor microfarad readings, contactor condition, amp draw against nameplate, and control-voltage checks. Finally, refrigerant: pressures, saturation temperatures, and temperature split tell us whether the system is correctly charged or leaking.
Reported AC repairs in the Stuart area commonly run $265–$383, with a broader range of $88–$754. The spread is honest: a capacitor and a hard-start kit sit at one end, a blower motor or a leak search sits at the other. You'll see the number before we start, and you'll never be pressured into a replacement to solve a repairable problem.
The failures we see most on the Treasure Coast
Salt air is the great accelerator here. Within a few miles of the St. Lucie River or the ocean, condenser coils corrode from the outside in, fins crumble, and cabinet fasteners rust through — coastal units often reach end of life in 6–8 years versus 12–15 inland. Lightning is the other signature problem: Martin County sits in one of the most lightning-dense regions in the country, and a single nearby strike can take out a capacitor, a control board, or a compressor.
Humidity does quieter damage. Systems that run nine to ten months a year grow algae in condensate drains; a clogged drain overflows the pan and suddenly water is dripping through a ceiling. Long runtimes also wear out capacitors and contactors faster than northern systems ever see. We fix the failure and address the cause — drain treatment, coil rinses, surge protection — so the same phone call isn't back in six weeks.
When a repair stops making sense
Repair is the right call when the failure is isolated, the part is available, and the rest of the system is healthy — a eight-year-old unit with a dead capacitor in a garage air handler is a morning's work. The math changes when corrosion is widespread, refrigerant is R-22, or a compressor fails on a unit that's already been limping along.
We'll put both options in writing when the decision is close: the repair cost, the likelihood of the next failure, and a replacement scope with equipment, efficiency, and permit work spelled out. Reported central AC installation near Stuart runs $5,800–$11,200, so a repair that buys three reliable years is often the smart money — and a repair on a corroded, R-22 system sometimes isn't. You get the facts without the sales pitch.

Our AC Repair process
Test first, document everything, and get your sign-off before the work happens — no guesswork, no surprises.
- 1
Listen and inspect
We start with your symptoms — when they started, what they sound like, what's already been tried — then verify the thermostat, filter, and power.
- 2
Test electrically
Capacitors, contactors, motors, and controls get metered. Amp draw is compared to nameplate so a failing part is caught before it dies completely.
- 3
Check refrigerant and airflow
Pressures, saturation temperatures, and temperature split tell us whether charge, airflow, or the metering device is at fault — and whether a leak exists.
- 4
Quote in writing
You get the failed part, the cause, and the fix with a line-item price. Nothing starts until you approve it.
- 5
Repair and verify
After the fix we re-measure: charge, split, draw, and drain. The system leaves verified, and the visit goes in your file with photos.
