We've got two 22 year old Trane units that are still using R-22 (man that's a lot of 2s). Reached out to my AC guy and while does suggest replacing them, he's advising we wait till 2025 for the manufacturers to roll out new systems using a new refrigerant due to something to do with new systems will be laid out/installed and manufacturer coverage/support for compressors changing with the refrigerant change.

Any validity to this?

Makes sense. He's coming by this week to check out the system to see if there's any minor repairs needed to make it last another year or see if it needs replacing now but I'll ask then.

Now I just need to find a quote on replacing all the insulation in the attic and seal up any leaks.

Previous owner had installed awnings around the house and both units are underneath them like below



I've read conflicting information about this affecting efficiency both positively, because it's shaded which I doubt, or negatively because the expelled hot air can't escape as easily. Should I go ahead and remove the roof panels over them?
