I'm having to replace my A/C, both outdoor unit and indoor components because they're freon based and apparently that's hard, if not impossible to find. The new unit will be a 4 ton 13SEER. The guy told me my current A/C unit was so old it didn't even have an efficiency rating. Well for the cost I'm going to be very good about remembering the tips above and any others anyone might care to share.
I've noticed other A/C units out by the street waiting pickup recently. Is 14 years about the life expectancy of an A/C system?
