Great Service, monet saving advice




this was the fall service. am part of the maintenance plan. Pricing for new parts was very good but even better was advice to shop for part on Amazon and the instruction of how to change the light bulb myself. Always advised of new options to install in case of an accident or flood.

I had 18 volts line voltage at the furnace. This told me that the furnace had two on/off switches instead of one dedicated switch and that one of the 2 was off. Flipped the switch on the ceiling and the unit cycled normal. Unit less than 2.5 years old and no other concerns mentioned by the customer.

Continued to test and furnace continued heating sequence until satisfied. Tried running furnace again and it faulted on code 45 control circuit fault.
