I completed a diagnostic and found round duct not hooked up to anything. Just dumping cold air into the basement. Showed customer and customer put duct tape over the supply. I also found the filter extremely dirty and right up against the blower. Compressor is getting old and showing. Amps are high because of the age. Condenser is from 2006. I recommended replacement to customer. Customer does agree to replace because of the age. Customer is going to wait till next spring to replace.
