Outdoor unit hums for 10+ seconds but compressor and fan don't spin. Classic capacitor failure — the start winding can't kick the compressor over. $185–$285 repair, takes 30 minutes.
Worn blower or condenser fan motor bearings. Replace the motor before it seizes and burns out the windings. $385–$695 depending on motor type.
Loose fan blade hitting the housing, broken compressor mounting bolt, or refrigerant slugging (liquid in the compressor — serious). Shut the system OFF and call us.
Failing contactor, loose 240V connection, or arcing relay. Fire hazard — shut the system OFF at the disconnect immediately and call us.
Refrigerant leak at the indoor coil or line set. Hissing = gas leak; bubbling = liquid leak. Both need EPA-certified repair.
Relay chatter from a failing control board, or a thermostat short-cycling the system. We diagnose with a multimeter on the 24V circuit.
Panels loosened by vibration, debris in the condenser fan, or a failing condenser fan motor. Cheapest possible call — usually $145 total.
Blower wheel touching the housing, bent blade, or motor mount failure. Doesn't fix itself — eventually destroys the motor.
“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.”

Some noises (banging, screeching, electrical buzzing) signal failures that can damage the compressor or start a fire if ignored. Turn the system OFF at the thermostat if you smell burning or hear electrical buzzing — then call us.
A loud hum from the outdoor unit that doesn't start within 10 seconds usually means a failed capacitor or seized compressor. Hard-start clicking followed by silence indicates internal compressor failure.
Common causes: loose fan blade, debris in the condenser, failing motor bearings, refrigerant overcharge, or a panel that's come loose. Most are 30–60 minute repairs once diagnosed.
