The answer to how to maintain an air conditioner is to perform regular cleaning and inspections. This includes cleaning the outdoor unit, changing the air filter, and inspecting the system for any issues. Proper maintenance can help extend the life of your air conditioner and ensure it runs efficiently.
Start by cleaning the outdoor unit every few months, removing any debris or vegetation that has built up around it. Use a hose to gently wash the coils and fins, being careful not to bend the fins. Change the air filter every 1-3 months, depending on usage and indoor air quality. Inspect the system for any leaks, unusual noises, or other signs of trouble, and address any issues promptly. It's also a good idea to have a professional HVAC technician service your system annually to ensure it's running at peak performance.
