I am about to have my existing 2-ton R22 condensor replaced due to what seems to be a bad (stuck) compressor. I am exploring the option of upgrading to the newer R410A. Is it as easy as swapping out condensors or does more have to be done in the conversion? In other words, will I have to make any changes in the inside unit as well? No, I am not doing it by myself. I've read that I should get one that has a Thermal Expansion Device (TXV) factory installed, and with a SEER rating over 14. Can someone recommend an affordable condensor that does this (R410A or R22). If conversion to R410A is much more expensive I would rather hold off for now. I'm in South Florida. Thanks.

First of all, do not make equipment decisions based on refrigerant. If you decide on an R-410a unit, do not pay more for it,not worth it.
1.Regardless of whether you elect to go with R-22 or R-410a AC condensing unit, go ahead and change your refrigerant lineset. Not worth an inexpensive shortcut.
2.If you stay with an R-22 unit and depending on condition, it is possible to keep and utilize existing evaporator coil or air handler. I would not recommend this as it is preferred to have a matched set for achieving comfort and rated efficiency.
3. If you elect to go with R-410a, the refrigerant lineset must be replaced along with your evaporator coil or air handler.
I do not like budget/builder model equipment.You should consider min 13-14 rated Seer units. Look at Rheem,American Std for quality. Most quality units have a built-in TXV in their evap coil or air handlers. There are cheaper units but you generally get what you pay for.
My opinion.
Good Luck!

How far south?? Im in west palm. You dont say what all is wrong here. If you get a new outdoor unit yes you need a new indoor coil also. Down here as much as we run the AC go for a seer of 16 or more. Also think of a hot water recovery unit on the AC thats free hot water for about 8 months here and kicks up the seer of the unit.
Now R410a Id say for now dont go for it. The cost of the freon is very very high. If you have a leak in it you cant just top it off like R22 you have to take it all out and put all new back in and you would need new copper lines for it also. They will make R22 till 2030.
Any more ??? post back in the same post here
