An air conditioner that is running but not providing sufficient cooling can have several possible causes. Common causes may include dirty filters, blocked coils, restricted airflow, dirty blower assemblies, refrigerant issues, condenser problems, fan motor faults, thermostat problems, drain-related issues or compressor-related faults. Instead of simply adding refrigerant without identifying the reason for poor cooling, our technicians can inspect the AC system and determine the underlying condition. We check the relevant components and recommend servicing, repair or replacement where required. AC WATER LEAKAGE REPAIR Water leakage from an indoor AC unit should not be ignored. AC water leakage can occur due to blocked drain pipes, dirty drain trays, drain pump problems, improper drainage, frozen coils, insufficient airflow or other system-related issues.
