Professional AC technicians can clean the condenser coils, repair refrigerant leaks, and refill the refrigerant to the proper level. If the compressor is damaged, they can either repair or replace it, depending on the severity of the issue.

4. AC Leaking Water

Water leakage is another common AC problem that Delhi residents often face. This issue can occur both indoors and outdoors and is typically caused by:

• Clogged Drain Line: The AC’s condensate drain line can become clogged with dirt, algae, or mold, causing water to back up and leak from the indoor unit.

• Frozen Evaporator Coils: If the evaporator coils freeze due to poor airflow or low refrigerant levels, they can cause water to leak when they eventually thaw.

• Improper Installation: If the AC unit is not installed correctly, it may not be level, leading to water leakage.

How Professional Repair Services Can Help:

Professional AC repair services in Delhi can clear clogged drain lines, preventing further water leakage. They can also address the underlying causes of frozen evaporator coils, such as cleaning air filters or repairing refrigerant leaks. Additionally, if improper installation is the issue, they can re-install the unit to ensure it is level and functioning correctly.

5. Strange Noises from the AC

Unusual noises from an AC unit can be alarming and may indicate underlying issues. Common noises include:

• Grinding or Squealing: These sounds often indicate a problem with the motor bearings or a loose belt.

• Hissing or Bubbling: These noises may suggest a refrigerant leak, which can be hazardous if not addressed promptly.

• Banging or Rattling: Loose or broken components, such as the fan blade or motor mount, can cause these noises.
