I have an Airease Ultra 5 Tec-80 downdraft furnace. I had water dripping off from inside the plenem in my crawlspace. The contractor thought that the high blower speed was blowing the water off of the a-coil so he decreased the fan speed. This sounds to me like a work-around. Is this right or was the a-coil/drain installed wrong? The contractor claims everything is installed correctly.
