I was a home service technician who was responsible for maintaining and repairing various household appliances. One day, I received a call from a client who reported that their air conditioner was not cooling properly. I arrived at the client's home and performed a thorough inspection of the unit. I found that the condenser coil was dirty and clogged with debris, which was preventing the unit from cooling effectively. I cleaned the coil and replaced the air filter, which resolved the issue. The client was very satisfied with the service and thanked me for my prompt and efficient service.
