Whole House Dehumidifier – Is it worth while?
I’m building a new home in Climate zone 6 (central PA). It will be well insulated and air sealed. While I’m still wrestling with the ERV vs dedicated bath exhaust fan decision, my HVAC contractor has just further muddied the water. We are going with a closed loop geothermal heat pump. He has recommended we install a whole house dehumidification system (with outside air capability). Specifically he recommends installing a Honeywell DR90. In theory this makes sense for those days that are not hot, but still humid. Any thoughts or opinions? Is it worth the net installed cost, $1400 net.
