Lee from Air Towne came out to have a look a my furnace and humidifier that quit working. He brought a circuit board for the furnace as its a common problem and replaced it which solved the furnace issue. As well, Lee determined the solenoid was the issue on the humidifier. He sourced a part and came back for a 2nd visit to replace it. The bonus was that Lee took the time to deal with Lennox and had the circuit board for the furnace covered under warranty. It was a great experience dealing with Lee and Air Towne and I would definitely recommend them.
