Inspecting an air conditioning system twice a year is advisable to ensure optimal performance and longevity of the equipment. This frequency typically aligns with the demand placed on the system during the cooling season and prepares it for potential strain during high-use times, such as summer.

The first inspection ideally occurs in the spring, before the system is put into full operation, allowing for any necessary maintenance and repairs to be addressed. This proactive approach can help identify potential issues early, such as refrigerant leaks or electrical problems, which can lead to more significant breakdowns if not resolved promptly.

The second inspection is recommended in the fall, focusing on preparing the system for any off-season conditions and ensuring that it's ready for any unexpected warm spells. Regular evaluations can enhance the unit’s efficiency, reduce energy costs, and extend the service life of the air conditioning system.

While varying suggestions exist for how often to check air conditioning systems, the twice-a-year guideline strikes an effective balance between ensuring thorough maintenance and being practical for most homeowners. Other options, such as annually or less frequently, could lead to missed issues that might develop within the system.
