Arrived to AC tuneup. Upon arrival I spoke with the customer who showed me the location of the furnace and air conditioner. I began by checking the systems static pressure. Here I found it to be extremely high so high that it had my magnahelic maxed out. Next I checked for proper temp split and blower operation. The blower wheel has started to develop debris build up. On the outdoor unit the compressor, fan, and capacitor performed within spec. The refrigerant temps and pressures showed proper heat transfer. I am having my supervisor out to solve the high static pressure issue. System running upon departure.
