I just put in a new 80,000 btu Bryant furnace & 31/2 ton heat pump(new 410 freon). This unit replaced a fifteen year old furnace and 3 ton a/c. I wanted a larger unit this time because the 3 ton didn't cool the house on really hot days. Here's the problem the trunk line under the house is flooding with condensation. I have wrapped the trunk line with bubble wrap insulation and it has filled with so much water that it's
sagging down. The blower speed is on high and the charge is ok on the heat pump. The duct start out as 10x18 and reduces down. The condensation goes about 15 to 20 feet before it stops. This thing really has me pulling my hair out. Any suggestions ?
