I am a highly skilled home service professional. I recently completed a job replacing an idler pulley on a residential HVAC system. The pulley was worn and had begun to make a loud noise, indicating that it needed to be replaced. To replace the pulley, I first removed the old pulley and inspected the shaft for any damage. I then measured the new pulley and purchased the necessary hardware. I installed the new pulley and secured it with the appropriate bolts and nuts. To ensure that the new pulley was working properly, I tested the system to ensure that the fan was running smoothly and that there was no noise coming from the pulley. I also checked the electrical connections to the motor to ensure that they were secure. After completing the job, I cleaned up the work area and made sure that the customer was satisfied with the results. I also provided them with instructions on how to maintain the system and prevent future issues. Overall, replacing an idler pulley on a residential HVA
