Performing precision tune up service on 1998 Trane system (AC and Furnace). Good thing we came out because the blower cabinet insulation came off the wall and was completely blocking the blower motor on one side, which is now fixed. System was starving for air and causing pressure to build up inside the furnace. System running much better, cleared out dirty drain line and added hard start kit to protect compressor motor.
