Troubleshooting Common AC Problems
Fluctuating temperatures and salty air demand a robust air conditioning system. When issues arise, understanding the root cause is key to effective troubleshooting. Common AC problems often manifest as decreased efficiency or outright failure, impacting comfort and energy bills. Recognizing these signs early can prevent minor issues from escalating into major repairs.
Common AC issues to watch out for include:
- Warm air: Insufficient cooling often points to a refrigerant leak, where low levels hinder heat absorption or a failing compressor, the AC's "heart," which circulates refrigerant. Thermostat miscalibration can also lead to inaccurate temperature readings.
- Loud noises: Banging indicates loose internal components like fan blades or a failing compressor. Rattling suggests debris in the fan or ductwork. Hissing usually signals a refrigerant leak, a potentially hazardous situation.

Professional AC Repair Procedures
Efficient AC operation relies on precise repair procedures. Our technicians prioritize restoring system functionality and longevity. From identifying subtle refrigerant losses to replacing essential components, we adhere to rigorous standards for every repair.
The following outlines typical AC repair procedures our team performs:
- Refrigerant leak detection and repair: Specialized tools are used to pinpoint leaks, often employing electronic detectors or UV dye. Once located, the leak is repaired, and the system is recharged to the optimal refrigerant level.
- Compressor replacement: A faulty compressor necessitates careful removal of the old unit, followed by the installation of a new, compatible compressor.
- Fan motor repair and replacement: Fan blades and motors are inspected for damage or wear. If repairable, issues are addressed. Otherwise, the motor is replaced with a new one.
- Thermostat calibration and replacement: Thermostats are calibrated for accurate temperature readings. If calibration is unsuccessful, the unit is replaced with a new, compatible thermostat, and proper wiring and settings are verified.
- Ductwork inspection and repair: Ductwork is inspected for leaks, damage, or blockages. Repairs entail sealing leaks with mastic or tape, repairing damaged sections, or clearing blockages.
- Evaporator coil cleaning and repair: Evaporator coils are cleaned to remove dirt and debris, improving heat transfer. If coils are damaged, they are repaired or replaced.
