Replace only outside unit?

I am in Ca, and I was wondering, Can I just replace the outside A/C unit, seeing as the rest of the HVAC system is in good shape and working? I have an old Rheem system from the mid 80`s.
Just recently had a tech out to check the system, and the condenser is deteriorated, but not leaking...yet. He said a full system would run about 10k(not going to happen) And, do I have to replace it with a Rheem unit, or can I use Trane, etc.? And I would like to do this myself, but i do realize that i may have to get a pro to come out and flush my lines and charge with compliant freon.

it is possible to replace the outdoor unit only. since you live in california i imagine that you have a fairly large sysem (4 or 5 ton) so you can just replace the condenser(outside unit) if its a half ton or 1 ton smaller than the coil you currently have. 10K is only for top of the line blah blah blah, on average most companies will charge 4k-5k for a complete system. and yes you can replace it with anything not just rheem. condenser is deteriated but does it work? do you have dogs that pee on the unit lol

Shop around, a 4-ton condensor unit should be around $2500 completely installed. 10K is way toooo.. much, may be he is talking about the whole system (inside and out, new 410a system, including line set in the wall.)

CA has stricter regulations than many other states, therefore, you may be required to replace the indoor coil.

Going to 410A makes it more important to change the coil & it's good practice to use all new piping.

I would never install a new indoor coil without a TXV refrigerant metering device, also want a condenser with a Copeland Scroll compressor...
