Here are my final options. Appreciate any feedback on which system sounds like the best one.
Comfort series condenser
Performance series variable speed fan air handler
Vision Pro digital thermostat
Prestige series (RPQL-JEZ) condenser
Prestige series (RHPL HM 3621 JA) variable speed fan air handler (I think the air handler is a 16 SEER)
Not sure about thermostat for this one
Thanks for your help!
