Just out of curiosity, I stuck a bucket under the condensate drain and found the system is wringing out about 5 gallons per day from our 1800 sq ft home in central Florida. Now, admittedly, it's humid outside, but should it be that humid inside? Is this a normal condensate volume?
However, I have the feeling that when the system is running, the house is slighty depressurized -- I can detect the smell of chimney when walking by the fireplace. I have no idea why that might be. The house is reasonably well sealed (I thought), and the ductwork inspected visually for leaks and sealed up with duct sealant at all joints, registers, etc. The house and AC should be an essentially closed system, but I must be actively sucking outside air in and pushing conditioned air out. Looking for ideas.
