I was called to a home to repair a unit that was not running in good condition. Upon arrival, I found that the unit was not producing any heat. After inspecting the unit, I determined that the pilot light was out. I replaced the pilot light and tested the unit to ensure it was working properly. I also checked the gas pressure and adjusted it as needed. After completing the repairs, I tested the unit again to ensure it was running in good condition. The customer was very satisfied with the work and paid me for the service.
