Run your vehicle and home air conditioning every now and then even in the winter. This circulates the freon and PAG oil in the system, preventing o-rings from drying out which reduces leaks that can lead to problems in the summer when you need it to work. Avoid several hundred dollar repairs by cycling the A/C even in winter.


....a good reminder; however, I've long made a habit of cycling the AC at least once a week whether it needs it or not.
