Performed AC cool checks on three systems. Checked the electrical, mechanical, safety, and performance of the systems. I cleared the condensation drain lines and flow tested the drains with water. I also treated the drain lines. The air filters were replaced with client supplied filters. The blower motor for the system in the laundry room/kitchen had failed. The motor was receiving power and signal to run however it would not run at the correct RPM’s and was stuttering while trying to run. Options for repair were presented to the homeowner. She chose to have the blower motor replaced. I left and picked up a replacement motor and returned to the job. I replaced the blower motor and function tested the system. The blower motor is now operational and the system is running normally. All three systems were running at the completion of service.
