I arrive the thermostat was just seen off. I was able to get it to run properly however customer opted to replace the thermostat to make sure that the furnace wasn’t going to stop working. I replaced the thermostat and showed customer how to use it. After getting the thermostat set up re-went down to the furnace area to make sure the humidifier works. The saddle valve is completely clogged up and so we need to replace that with a quarter turn valve so the humidifier has water. Customer would like to be called to schedule the furnace, tuneup, and allow for enough time to fix the humidifier as well.
