Complaint furnace making buzzing sound Upon arrival tested system operation and did not hear any clicks or buzzing, inspected all wiring connections and tightened them up. Found mouse or mole fried on capacitor, this is most likely the cause for buzzing. Cleaned up connections at capacitor and tested system operation in cooling, heat pump, and emergency heating modes and found no issues System is heating at this time

I appreciate Daniel taking the time to figure out what caused the problem and coming up with a solution. Also, I was not home when the solution was installed but Daniel took the time to leave a note stating what work was performed and further instructions for me regarding maintenance. Thank you.
