I see ultra aire has one really effecient one out but it is way to big for my house. I would really like to get a whole house dehumidifier and have dedicated ducts for basement ventilation. Anyone know of something in the 90-100 p/day range with an effieiency of around 3 p/kwhr or more. Everything seems to still be r22. Most contractors around here still perfer r22 for everything.
