I have seen a lot of commercials for AC company specials on a "tune up", which they recommend doing annually. They advertise it for $50-$80. It basically sounds like they just check your system for something wrong.
I have never done any maintenance other than changing the air filter unless the AC isn't working right. I did have an AC problem recently and had a blower fan that needed replacing and they had to add some refrigerant. Would annual ture ups prevent bigger problems? I have been assuming that a tune up is just an excuse for these companies to "find" something wrong that costs you a lot more and is more profitable for them. Like when I had recall work done on my car at the dealership and recommended $800 worth of maintenance items, most of which I know were unnecessary (like changing the transmission fluid at 30K when the manufacturer recommends it at 120K, an alignment every 15K even though my alignment was fine, and tire rotation every 5K).
Does anyone do regular A/C maintenance tune ups and what is the benefit?
