@topcatGive Charlie a call, dude.... That's who put in our new unit, insulation, etc, just last year as well, and he made it clear that if we ever experience any type of issue, or concern, to call him ASAP - he's actually always on-call, and should answer.... And no, he should NOT charge you, as your unit's still under warranty....Charlie # 281-772-5595 (This is his direct cell number....) 4951
