Yes, the car AC compressor can wear out faster when it is not used for an extended period, such as during the winter season, compared to using the AC regularly throughout the year. This is due to several factors:
Lubrication: The AC compressor relies on refrigerant oil for lubrication, which helps reduce friction and wear on moving parts. When the AC is not used for an extended period, the refrigerant oil may settle and not circulate properly throughout the system. This can lead to inadequate lubrication, causing increased wear on the compressor when it's eventually used again.
Seals and O-rings: The AC system has seals and O-rings that keep the refrigerant contained. When the AC is not used, these seals can dry out and lose their elasticity, making them more prone to leakage and potential compressor damage.
Corrosion: Lack of use can allow moisture to accumulate in the AC system. Over time, this moisture can cause corrosion in the compressor and other components, leading to reduced efficiency and potentially early failure.
On the other hand, using the AC regularly throughout the year can help maintain its components in better condition. Regular use keeps the refrigerant and lubricant circulating, preventing potential issues caused by prolonged inactivity. Additionally, using the AC regularly can help identify any problems early on, allowing for timely maintenance and repairs, which can extend the compressor's lifespan.
To minimize wear on the AC compressor during periods of non-use, it's a good idea to run the AC for a few minutes at least once a month, even during the winter season. This helps keep the system lubricated and can prevent some of the potential issues that arise from extended inactivity. If you live in an area with milder winters, occasional use of the AC during the colder months can be even more beneficial for the system's longevity.
