I was called to a home in Tucson, Arizona, to perform winter maintenance on a 6-year-old carrier split unit. The unit was not cooling properly, and the customer was concerned that it might need to be replaced. Upon arrival, I performed a thorough inspection of the unit and identified the issue as a dirty air filter. I cleaned the air filter and replaced the blower motor. After completing the repairs, the unit was cooling properly again. The customer was very pleased with the service and expressed gratitude for the quick and efficient repair. I explained to them the importance of regular maintenance and how it can help prevent costly repairs in the future. Overall, the job was a success, and the customer was happy with the results. I am proud of the work I did and the positive impact it had on the customer's home.
