I have a newer Rheem RGTM10EBRJS down flow configured system. The in-slab duct work in my 2100 square foot rancher home appears to be small and the system itself is oversized for my home. Consequently, when the blower kicks on the system is very loud. Short of relocating the duct work (which is expensive) what can be done to alleviate the noise?
Thanks in advance.
