Carrier builds reliable equipment — but Florida is brutal on HVAC systems. Salt air, 80% humidity for six months, daily lightning, and 95° heat compound failures that wouldn't happen in a milder climate. Here's what we see most often on Carrier systems across the Treasure Coast.

Heat is the enemy of capacitors. A 370V/440V dual-run capacitor in a Florida condenser cabinet hits 140°F+ on a summer afternoon. They're rated for 65,000 cycles but Florida heat shortens that to 5–8 years. When the capacitor fails, the compressor or fan motor won't start. Cost: $200–$450 installed.
Florida lightning + frequent cycling pits the contactor's silver contacts. Eventually they weld closed (compressor runs nonstop) or fail open (won't run at all). We replace contactors at maintenance when we see >0.3V drop across them. Cost: $250–$500 installed.
Formicary corrosion eats microscopic tunnels in copper coil tubing. It's caused by VOCs (volatile organic compounds) in indoor air — cleaning products, new carpet, paint. Florida homes are sealed up for AC use, which traps the VOCs. Carrier's aluminum coils (post-2015) resist this much better than older copper coils.
Within 1/2 mile of the ocean, salt aerosol coats the condenser coil. Without monthly coil rinses, the fins corrode and airflow drops. The system runs longer, hotter, and the compressor eventually fails. Carrier's WeatherArmor Ultra coastal coatings help, but rinsing is non-negotiable.
Florida humidity means heavy condensate production — a 3-ton system can produce 20 gallons a day. Algae and biofilm grow in the drain line, clog the trap, and trip the float switch. The system shuts down (correctly) to prevent water damage. EZ-Trap tablets every 6 months prevent this.
Carrier Infinity control boards are sensitive electronics. A nearby lightning strike can fry the outdoor inverter board ($600–$1,100) or the Infinity Touch thermostat ($450–$700). A $150 surge protector at the disconnect prevents 95% of these failures.
Restricted airflow (dirty filter, dirty coil, kinked duct) or low refrigerant causes the coil to drop below freezing. Ice builds up, melts when the unit shuts off, and floods the pan. Most service calls labeled 'no cool' are really 'frozen coil from dirty filter.'
“My highest recommendations for Devon and the Maritime Air team — thorough, honest, and on time. They explained everything in plain language and didn't push any unnecessary upsells.”
“Devon has provided thorough maintenance and excellent service. Truly family-owned care — they treat your home like it's their own. Highly recommend for Treasure Coast homeowners.”
“Working with Devon on my HVAC system was a great experience from start to finish. Fair, clean install, and the system has been running perfectly through Florida summer heat.”

Florida heat. A capacitor in a 140°F condenser cabinet on an August afternoon ages faster than the same part in Ohio. Plan on a capacitor every 5–8 years and you'll never be surprised.
Rinse the condenser coil with fresh water monthly (a garden hose is fine — no pressure washer). Replace the filter every 60–90 days. Get the system maintained twice a year. Install a surge protector.
Yes — a properly sized system will run 60–80% of the time on a 95° afternoon. If yours rarely cycles off, it's working hard but not necessarily broken. If it never reaches setpoint, that's when to call.
