You should also run the air conditioner regularly, even in the winter, so that it lubricates itself and keeps the seals from drying out. The seals can crack and that leads to leaks. Your owner’s manual will have recommendations for how often to service your air conditioner. Some Glendale automotive service centers also have this information as part of their computer databases. A service advisor at Kerry’s Car Care can give you more information. Call (623) 939-9491 to schedule an AC check.
