Hello, if you shop around extensively you can probably get the furnace replaced for $3,500 or less.
The problem may or may not be with the smart valve, it will take me an hour or a lot longer to step you through a diagnosis. You will need a multi meter for that.
Let me know if you are interested in that, I will submit a $40 'additional service' offer in that case.
