Good afternoon and happy holidays! I just had a Trane RunTru 5 ton ac unit installed. The air handler tilts towards the back and to the right. The drain is in the front left. The installer said that the tilt is OK because the drain pan is angled forward. The installation manual says to mount the air handler level or tilting up to 5° forwards. Does Trane make their air handlers with the drain pan at an angle facing forwards? And even if they do, shouldn’t the air handler at least be level? Thank you!!
