Help needed. I recently brought a brand new raised ranch with nobasement. The second floor is taking about 3 hours to raise 2 degrees (68F to 70F) even when the outside temperature is around 20C
Where as the first floor takes only 1 hour to raise 10F
(ie. from 60F - 70F).
I had talked to installer about this he is saying this is normal.
