My furnace is making a somewhat loud humming noise. I first noticed it a week ago but then it stopped. Now it's doing it again. Any ideas why?

I think it's hungry.

I could say it doesn't know the words but I won't. Tow probables........There is a low voltage transformer used to power the thermostat and control board. Also the fan motor if out of alignment or about to expire will hum.
 
It could be the belt between the fan pulley and the motor has stretched and is starting to slip. A simple tension adjustment would fix that.

That would be a squeal not a hum
 
It could be some humming birds that accidently flew in. Save the birds please.
 
When was it cleaned last ?

If you want cheap forced air gas heating

I can look at it for the low, low price of 45 roses per hour...........But i only offer incall :p
 
Bearings in the furnace motor.

My advice: Direct Energy will sell you all of the protection you could possibly want. They come in they clean your furnace they "analyse" it and you pay two hundred bucks. Then; nooooo problems for you.
