Without quantitative measurements, your just guessing
Why not? You got the same attitude.
Apparently not, your still screwing around with stuff you don't know anything about.
You "licensed" installer is an idiot, and the evap coils should always be dry except when the system is running in cooling mode.
Then if ignorance is bliss, you must be euphoric.
How do you *KNOW* if its working or not without actual measurements?? The accepted method is to call somebody who actually knows WTF they are doing and not just the lowest bidder.
FWIW, the ideal indoor humidity levels are very specific. Too high or too low will promote groth of viruses and molds. There is a very narrow bell curve of temperature and humidity level where viruses and mold will not grow.
Guys correct me if I am wrong here, I am going off the top of my hear from one of Lew Herimans seminars a couple of years ago.... Summer indoor temp 75-78 with 45% - 55% RH Winter indoor temp 68-72 with 40% - 50% RH Here in south Mississippi, I design for summer cooling temp/humidity 75 degrees @ 50%RH.
