Air conditioners typically do not spoil or degrade if they are not used for an extended period of time. However, there are a few considerations to keep in mind:
Dust and dirt: When an air conditioner is not used for a while, dust and dirt can accumulate on the filters, coils, and other components. This can potentially affect the unit's performance when you start using it again. It is recommended to clean or replace the filters before using the air conditioner after a long period of inactivity.
Moisture and mold: If the air conditioner is stored in a humid environment or not properly protected, moisture can accumulate inside the unit. This can lead to the growth of mold and mildew, which can negatively impact the air conditioner's performance and indoor air quality. It is advisable to store the unit in a dry and well-ventilated area to prevent moisture buildup.
Mechanical issues: While not using an air conditioner for an extended period is unlikely to cause mechanical problems, it is possible that existing issues may worsen during the period of inactivity. For example, if there was a minor refrigerant leak or a small fault in a component before the unit was not used, it may become more apparent or cause further damage over time. Regular maintenance and inspections can help identify and address such issues before they worsen.
To ensure optimal performance and longevity of your air conditioner, it is generally recommended to run the unit periodically, even if it's not needed for cooling. This helps to circulate the refrigerant, prevent component dry-out, and keep the unit in good working condition. If you anticipate long periods of inactivity, it's a good idea to follow the manufacturer's guidelines for storing the air conditioner properly and consider scheduling maintenance before and after the idle period to ensure it is in optimal condition when you start using it again.
