Installed Goodman 13 SEER 3 Ton Heat Pump System Refrigerant is R410A. Air
Handler is located in a half-basement-it is an upflow unit. The air handler is sweating on the inside-have checked returns in basement & crawlspace-all are sealed. Trap was added to condensate line-thinking unit was pulling water
back inside-trap did not help. Air-Handler is a Goodman ARUF 4236. Would appreciate any suggestions-Help!
