Just curious if anyone's knowledgeable about Furnaces. I have a Coleman Evcon DGU10020UB (gas, forced air) made most likely in 1999. It's heating the house fine but I've noticed the past week or so that when the blower kicks on it has a gotten pretty loud for the first 2-3 seconds before it just starts blowing air like normal.
Anyone with any guesses? Blower going bad maybe? Normally I can find most information via google and diagnose/fix myself without having to call a serviceman but I'm not having much luck this time.
