Diagnostic & Checkup
Visual Inspection:
Outdoor Unit:
Check for physical damage, debris, or signs of water damage.
Inspect the condenser coils for dirt and obstructions.
Verify the fan blades are clean and rotating freely.
Indoor Unit:
Inspect the evaporator coils for dirt and debris.
Check the air filter for cleanliness.
Verify the blower fan is operating correctly.
Examine the condensate drain pan and drain line for clogs.


By systematically checking these components and performing the necessary tests, you can accurately diagnose the problem and determine the appropriate repair or replacement. For complex issues or if you're unsure about any step, it's best to consult with a qualified HVAC technician.
