The client called me to fix their air conditioner. I arrived at the house and found that the unit was running in fair condition. I checked the thermostat and found that the temperature was set to 78 degrees. I adjusted the thermostat to 72 degrees and tested the unit again. The air conditioner was now running in good condition. I made sure to clean the air filter and check the refrigerant levels. The client was happy with the service and paid me for the work.
