    Old High velocity AC system

    We have a customer who has an old Dunham Bush / Spacepak High Veocity AC system installed in 1971. Can just the condenser be replaced? Can just the Condenser, Air Handler/coil be replaced without changes to existing distribution systerm? The existing system has been relativly trouble free since installation probably should be in a museum.

    Depends

    The RIGHT way would be a new air handler and outdoor unit. That also could mean additional supplies for increased airflow. But if they refuse, you could find a "dry 22" condenser and slap it on that relic and hope for the best.

    1971 ?

     For an evap coil//blower , 40 years is RARE ! Let me say again, RARE!!! .Now,the system ducting,is a different story,depending on a few things.The " SEER " rating of the evap would be real low ! Maybe 6-8 ?  Was SEER around in 71' ? Was it EER?  O.K. now, the SEER of the "dry charged "  is 13 and thats not good math !
