Just replaced a 10 year old 10 Seer Trane system with new 12 Seer Trane system in my upstairs system. Both the compressor(1.5 ton) and the Air handler(2 ton) were replaced.
The upstairs part of the house still will not cool down.
While there are many things to consider, what bothers me the most is the lack of condensation on the freon lines at the new compressor. It appears to me that the new compressor just isn't getting the freon cold enough. This is true even at night when the heat gain is substantially less.
The compressor for the downstairs system(4 tons) sits next to the new compressor and its freon line is cold and wet. The freon line connected to the new compressor is warmer(to the touch) and dry.
Day or nite, the large downstairs AC system is draining a good amount of water while the smaller upstairs system is dry.
I am thinking that since the upstairs system cannot cool the freon sufficiently to produce condensation, it isn't working properly.
Thanks for any insights
