no problem... would still be glad to help out with suggestions....not all A/C companies are just in it for themselves. Most of us want to help out and raise the standard of the industry.

I don't have a price yet, but he told me if I want to go with 14a, he'll have to change the coil in the attic. What exactly is the coil (i.e. a whole new box or just a part inside of a bigger unit), and is that an expensive thing?
He still sells one unit that uses the old freon, but would have to retrofit it (~ $300) later if the inside unit went out.

Does all of that make sense, and do you recommend changing to the 14a?
