I was called to replace an indoor coil in a residential home. The customer was not home, so I had to wait for them to return. When I arrived, the temperature inside the unit was 90 degrees, and the supply air temperature was 67 degrees. I removed the old coil and installed the new one, ensuring a proper seal. I also checked the electrical connections and tested the system to ensure it was operating correctly. Finally, I cleaned up the work area and made sure the customer was satisfied with the job before leaving.
