Imagine this scenario happening to you: It is a hot summer day, and you are planning on getting away for the weekend. Your drive is about 3 hours away and you can’t wait to reach your destination because it involves a lake or a beach and a whole lot of fun. Right as you go to turn on your car, you notice your A/C system is not cooling. Now you have to decide whether you want to drive 6 hours round trip in the smoldering sun or cancel your weekend plans to take your car in to an A/C technician. All of a sudden the weekend getaway you were looking forward to is not so exhilarant.
You vehicle air conditioning system is pretty dependent on all the parts in the AC system. If something isn’t working, then you can bet you are going to know it on those hot, hot summer days. Your AC expansion valve is a pretty simple part in concept, but it has a very important job when it comes to whether you just get air instead of cool air.
