Derrick is exceptional!

Derrick was absolutely a pleasure to work with. He treated me like I was a member of his family. It was clear that he was not just concerned about getting the account; he was concerned about my health. Specifically, I have a significantly amount of black mold, which could do great harm. Thank you, Derrick! You are a class act!

The customer called to report that their propane fireplace was not working. I arrived at the customer's home and found that the pilot light was out. I checked the gas line and found that it was not connected properly. I reconnected the gas line and the pilot light came on. I tested the fireplace and found that it was working properly. The customer was happy with the service and paid me for the service.

I performed furnace maintenance on a residential property. I verified the operational performance of the system, cleaned the carbon buildup on the flame sensor, and assessed the amp draw of the blower and inducer motor to ensure they were operating within acceptable parameters.
