Today I discovered the system in terrible shape the blower wheel has broke free from the motor doing so damaged cap the electrical housing and wiring. This is a r22 lennox heat pump. I can replace the wheel and housing but I can not cerntinly say this will fix the system because of the age of all this. It may be the case that the cooling side or even the heat pump don't operate or barley operate. This is something I can't know until the system is at least functional. System is down. They want to talk to ca this Monday 10 am about replacement
