I was called to a home to change the air filters, clear the condensation drain, and clean the coils. I arrived at the house and began by changing the filters. The air filters were dirty and needed to be replaced. I then cleared the condensation drain, which was clogged with dirt and debris. The coils were also cleaned, which helped improve the efficiency of the air conditioner. After completing the job, the customer was happy with the results and thanked me for my service.
