I have a ten month old 13 seer hvac system with puron technology and all new ductwork. About four months ago I noticed an antifreeze like odor near the return. Now there is a heavy almost putrid odor coming through all of the vents. It is worse in the airconditioning mode. Does anyone have any idea what is causing this. Unit has been inspect twice by installer, can't find anything. Carrier, 38YXA, 5 ton.
