Need Help Buying Air Conditioner

Hi Guys:

Hope everyone is doing ok.  I know this is completely Off topic but I need some help.  I'm going to be replacing my central air conditioning system.  I've been looking at  a Goodman Heat Pump,
4 ton.  That's What I have now but it is 15 yrs old and not efficient anymore.  My question is; do any of you have a Goodman System that isn't more then a couple of years old?  Could you tell me if you have had any problems with it since it was installed?

I would really appreciate any and all responses about Goodman Air/heat Heat Pump units.

Thanks for your help.

Sincerely,
Susan G.
