Common AC Faults
Insufficient Cooling
Usually caused by low refrigerant (gas), dirty evaporator coils, or a clogged air filter hindering airflow.
Water Leakage
Occurs when the condensate drain pipe is blocked or the evaporator coil freezes due to low gas levels.
Strange Noises
Grinding, buzzing, or rattling sounds often point to loose fan blades, motor failure, or compressor issues.
Short Cycling
The unit rapidly turns on and off, suggesting a thermostat malfunction or an oversized AC for the room.

Always ask for a post-repair warranty on both parts and labor to protect your investment.
Cost Transparency
