I have a bryant up furnace. The blower works fine, but the air coming out of the vents is weak. The copper line going into the top of the furnace has ice on the outside and water is dripping on my filter inside. When I pull back the rubber ring around where the copper line goes into the furnace it has ice on the end as well.
Do I have a clog in my drip line or has the system just been working overtime? If a clog, where do I unclog?
Thanks a lot
