Upon my arrival I checked into the concerns of the system not heating. Performing my diagnostics I found that the heat pump is performing to specs but the auxiliary heating system has a failed heating element. When the comfort control was installed and the auxiliary heat wired back in there is no proof that it was tested to verify they were working at that time. Today I waived the service fee since if it was checked at that time we could have made corrective actions. I will be emailing over the repair estimate and the customer will get back with us whether they wish to move forward or not.
