For me, I keep a spare humidifier solenoid valve, since my hard water seem t gum mine up annually.
I always have extra humidifier evap pads around too, since new pads are cheaper than CLR to clean them.
I should probably keep a water tank thermocouple on hand, although I don't have it yet.
If we all get organized, we can save the group some real dollars through this heating season. What parts and procedures do YOU use?
