One of our customers recently asked for advice regarding an offer for a free air conditioning check at a local auto repair chain. This happened to be a popular chain of muffler shops, but I've seen similar offers at all kinds of shops. She was wondering whether these offers were tricks to charge you for something or if she could actually have her system looked over for no charge. The answer is yes, you can leave these shops with a free AC inspection. Of course they're going to try to sell you something, but that doesn't mean you have to buy it. Remember this however, if your AC was blowing cold, you probably don't need any additional freon. Of course the best way to assess the condition of your system is to test it yourself. A quick and inexpensive check will tell you if you have enough freon and if your system has a leak.
