How Long Can an Air Conditioner Sit Without Being Used?
An air conditioner can generally sit unused for a significant period, such as several months to even a year, without serious issues. However, proper maintenance and preparation before and after long-term inactivity are recommended to ensure it functions correctly when needed.
In the fall, you should clean and cover the outside unit to protect it from winter weather. Throughout the winter season, we also encourage homeowners to clear the area around their outdoor unit, checking to make sure there is no debris buildup and that no animals are attempting to nest or roost in the unit.
Risks of Prolonged Inactivity
Prolonged inactivity can pose several risks to your air conditioning unit. One common issue is the accumulation of dust and debris, which can clog filters and coils, reducing efficiency and increasing energy consumption. Electrical components may become corroded, especially if exposed to moisture, potentially causing shorts or failures upon restarting. Additionally, stagnant moisture within the unit can contribute to mold growth, leading to unpleasant odors and potential health hazards.
Before using your cooling system in the spring, you should uncover it and ensure everything looks clean and in good condition. This is also a great time to replace your air filters. Then, you should test your system, noting any signs of trouble.
