R2000 Home and humidity


Hello all, We recently purchased a 3 yr old home , it is 1,400.00 (apx) square foot on the main level and basement is unfinished, the house is equipped with an VanEE air exchanger , however we are not using it at the moment, we did just put in a 2 and 1/2 ton central air unit, ( according to the specs this is the apropriate size) we have been able to get the humidex reading down from 82 percent to 70 using the dehumidifer in the basement and the CA turned to 72 degrees, but* we cant get the humidex reading below 68 0r 69 percent,

is it acceptable to have humidex readings this high? and does anyone have any suggestions as to how to get it lower if it is not acceptable, at least the bed sheets and furniture does not feel damp now as it did when we moved in

also is this always going to be a problem with an air tight home?

R2000 Home and humidity


The HRV should be running always. An R2000 house is too well sealed for air exchange. That is why they install HRV in these homes.

2.5 ton sounds way oversized for the sq footage in an energy efficient house.
