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?

Depending on how old your inside unit is or if you don't plan on staying at your current house long, then it is almost always a good idea to change both the outside and inside units at the same time so that they match and then you get a much longer warranty as well.

410A would most likely need an evaporator coil replacement ($1500.) unless your coil is less than 10 years old. If you have a gas furnace in your attic it would be the box above your overflow pan. If you have electric heat it is probably part of your coil/blower and, if not available, you would need to change the electric air handler unit($2200.)...unless less than 10 years old. If you go with the dry charge or freon 22 unit there would be no retrofit needed later on ....just change the coil and possibly the metering device and you are good to go.
The advantage you have with the 410A system is efficiency....you can reach up into the 20 SEER (seasonal energy efficiency rating) as opposed to the max of 13 you achieve with the freon 22 system. This means a smaller utility bill each month...but unless you are ready to spend the money to go to at least a 16 seer system....go with the freon 22 or dry charge condensing unit and save the money.
