Today I arrived in Lincoln and met with the homeowners regarding HVAC System. I evaluated the concerns and found the Defrost Control System is faulted. I also checked the other electronics and found the Voltage Enhancement System is rated at 80 but is dead at 0.0, the system has original components and my main recommendation today was a complete Outdoor Renovation. In the mean time customer signed up for comfort plan, customer would like to have the price of unit replacement prior to approving repairs so Karl and his wife can weight the pros and cons.
