The answer to 'how to clean central air' is to regularly clean and maintain your HVAC system to ensure it operates efficiently and safely. This includes cleaning the condenser unit, replacing air filters, and inspecting the system for any issues.
Start by turning off power to the unit and removing any debris or vegetation around the condenser. Use a garden hose to gently spray down the coils, being careful not to bend the fins. You can also use a soft brush to remove any built-up dirt or dust. Next, replace the air filters according to the manufacturer's recommendations, typically every 1-3 months. Finally, visually inspect the system for any signs of damage or wear and tear, and address any issues promptly to prevent larger problems down the line.
