While your AC unit can perform great and keep your home cool if installed properly, there is always room for error. Some reasons for nonperforming units include incorrect installation, poor service quality, and inadequate maintenance. At Bold City Heating & Air, we want to help you understand how issues arise and how we can fix them. Call (904) 379-1648 for the best air conditioning service in Jacksonville, FL.
Some Common AC Problems
Refrigerant Leaks
If your AC is low on refrigerant, it could have a leak or was undercharged when installed. Adding refrigerant won’t solve a leak — our technicians fix the leak, test the repair, then recharge the system correctly.
Electric Control Failure
Compressor and fan controls wear out over time, especially when the system cycles frequently or is oversized. We check electrical connections and terminals for corrosion during every service visit.
Sensor Inaccuracies
The thermostat sensor measures air entering the evaporative coil. If mispositioned or touching the coil, the unit may cycle constantly or kick on randomly.
Poor Drainage
Humidity can cause units to drain poorly. Check the condensate drain for clogs or debris. Room units may not drain if incorrectly mounted and not level.
Bad Wiring
Poor wiring restricts power to the condenser motor, blower motor, and compressor. Faulty wiring can trip the circuit breaker and become a fire hazard.
Dirty Evaporator Coil
A dirty coil restricts airflow, overworks the compressor, and eventually freezes up. Have coils cleaned every 2 years and change filters regularly to prevent buildup.
Contactor Closed
When cooling is called for, the contactor closes to pass high voltage to components. Melted or broken pads on a faulty contactor will block that voltage entirely.
Humming Compressor
A distinct humming noise often signals a faulty compressor, commonly caused by low charge of Freon R-22 or Puron R-410a refrigerant.
