A couple of furnace questions.
1) I have a 5 year old high efficiency furnace. Does it need annual cleaning and checkup? I am think that once every 3 years should be fine. Also, does $100 for cleaning and checkup sound like a fair price?
2) My furnace has a built-in humidifier. I changed the pad. I noticed that there is a little plastic tube at the top of the pad that is suppose to feed water into the pad but the tube didn't have any water when I disconnected it to change the pad. How do I know if the humidifier is working and that water is being fed into the pad?
