Per Teddy Bear's recommendation, when I install my new Carrier Infinity system into my home, I am going to add a dehumidifier and some ventilation.
TB recommended an Ultra-aire dehumidifier, but my contractor has no experience with that and wants to go with an Aprilaire dehumidifier. Are there any advantages to one over the other?
Also, for ventilation, my contractor plans on just having a fresh air duct go from the outside to just before the filter on the return side, with no additional motor or anything special to move the air. Just a plain duct, with a damper in it, and the plan is for the blower motor on the furnace to do the work to draw the air in. But I see on the Ultra-aire that they have a "ventilating dehumidifier" that does both dehumidifying and ventilating at once. Why would these two things be combined? What makes the unit "ventilating?" If you have a duct from the outside draw air to the point right before ANY dehumidifier, doesn't that make it "ventilating?" Am I missing something here?
