I just got a new 2 ton Trane system for our upstairs. The air handler is a Hyperion (GAF2 series). I have a few issues I'd like to run past the pro's for comments. This system in a vertical installation in a walk in attic and has a strip heater installed.
1.) This system is louder than the old contraction grade Carrier system it replaced. Seems to be moving more air and/or the air is more turbulent and causing more noise.
2.) When the system turns on, the contactor (relay) is really loud. Sounds like someone is closing and latching one of the doors upstairs. When my wife heard it she thought someone was actually upstairs.
3.) It leaks a considerable about of air around the middle door that covers the coil. Specifically around the point where the condensation drain exits.
The build quality of both the inside and outside units seems very good, but I'm not happy that the system is louder than lesser quality system is replaced. The loud contactor is probably the most annoying, but the added "air noise" isn't too pleasant either. The air leak could obviously be fixed with some foam and tape, but it would sure look cheesy to put foil tape on a system that tries to look so good (not the end of the world I know).
From reading the installation guide, looks like the unit ships from the factory with the fan motor set up on tap 2 (medium speed). My thought was to lower the fan speed, but I read in the installation manual that you're not supposed to do this if the unit has a heater installed. Is this correct? Any chance the installer would have set it up for tap 3?
Any advice would be appreciated. Are there any service bulletins on the contactors? From reading other threads it seems there are some on the door leaks.
