I had a technician install my outside condenser. Model # gsc140421ac . I want to change the inside air handler because its an older ruud unit. What is the model number for the unit I am looking for? If the outside is a goodman I'm assuming it would be best if the inside is a goodman match right?

How old is the outdoor unit? How old is the indoor? Is the new ac 410 or 22? Why not have the same guy put in the indoor unit?

The outdoor unit is a 2008 r22 model and the inside is 2002 ruud.

If you change you will get better eff out of your unit. Right now you have a 10 seer indoor and 13 seer outdoor. Any brand will work, but mite as well go with goodman if that is what your ac is. Plus it will be cheeper.
