Trane A/C System Capacity Reduction
My five year old Trane HVAC system includes an XV90 (UY100R9V4w) with a 5 ton Condenser (2TTB0060A) and coil (2TXCC060AC3HCA).
It is oversized for my home. The A/C short cycles and humidity is not well controlled.
Also, the ducts are too small for even the lowest A/C airflow setting and there is quite a roar from turbulence in the return air duct and thru the grill.
I would like to reduce the A/C to a 3 ton capacity (which is adequate for our mild climate).
Two questions, please:
1) Can a new 3 ton condenser work with the 5 ton coil I have now (guessing no)?
2) If I swap the existing 5 ton single stage condenser for a 5 ton two stage unit (Xl16i), will that work with the existing 5 ton coil?
