Since then I have noticed a remarkable difference as far as my comfort. However, the humidity is still on average around 55%. Generally it's lower at night 51% or 53% and can stay as low as 55% during the day depending on what temp I set the thermostat and the rh outside. Today the rh outside is 65%...so in order to keep the rh around 55%, I have to set the thermostat lower. I went ahead and switched the fan speed back to medium after I did the vents. It didn't seem to affect the humidity levels in the house. When rh was running low (35%) here for a few weeks, the internal rh stayed around 55% with the thermostat set on 71 or 72. When the rh gets higher outside, it seems to become more uncomfortable for me and my wife.
I called Beco services today. I talked to Bruce. He seemed nice and competent. I'm sure he is totally worth what he is asking. He said that in this area I shouldn't need a whole house dehumidifer. So that leads me to believe that my unit could be too big. After some research, it is estimated that around 50% or more of homes out there have some type of AC issue whether it be too big...leaking systems. Bruce said he couldn't be sure about anything until he comes out and looks around.
I have to ask a question at this point....I am in a 4 year old house and i am looking at the possibility of changing my unit. I thought by buying a newer home, I would avoid having to pay a lot of money on issues like this. With all due respect to all the professionals on this board....What are the training schools for AC doing? It's no wonder so many people are skeptical of AC people if many guys can't even get a brand new install right. I just spent $$$ on this thing in January. Now I'm looking at possibly changing my unit. I've looked up in the attic and I don't see any bad practices as far as flex ducting going on.
I'm just totally at a loss about what to do....new unit....whole house dehumidifier....$$$$ here....$$$$...there....on a 4 year old house.
