I am a highly skilled and experienced home service professional. I recently completed a job replacing a blower motor and squirrel cage system for a furnace. The old motor was noisy and not working properly, so I replaced it with a new one that is quieter and more efficient. I also replaced the squirrel cage system, which is the part of the furnace that moves the air through the vents. The new system is up and working great, and the customer is very happy with the results.
