I arrived at the client's home to perform a routine maintenance check on their heating and cooling system. Upon arrival, I ran the unit in heat mode to ensure it was operating correctly. The unit stayed on and checked the operations, and the gas valve was at 2.6, which I turned to 3.1. The unit had a temperature of 133 degrees coming from the furnace. I noticed that the unit was not turning off, so I checked the thermostat and found that it was set to "auto" mode. I reset the thermostat to "on" mode and the unit turned off as expected. I also checked the air filter and found that it was dirty, so I replaced it with a new one. After completing the maintenance check, I tested the unit again to ensure it was operating properly. The unit was running smoothly and efficiently, and the temperature was within the desired range. The client was satisfied with the service and thanked me for my help.
