there is a banging noise in heating duct shortly after furnace comes on it
only happens once. Is this due to the expansion of the sheet metal? |

When the fan goes on the pressure in the ducts change and some of them may flex in or out. You may notice that larger panels are often creased to provide a little more strength to prevent this problem. If you hunt down the specific part that is flexing you may be able to shim or stiffen it to eliminate the sound. -- Joseph Meehan 26 + 6 = 1 It's Irish Math |

Sounds like a demon. Better call TAPS.

I watched that show last night.... finally was forced to turn the
channel when I saw em flashing that $10 temp probe around and being astounded when it went from 60 to 50 to 45 to 60..... Well, um.... DUH. The every 15 minute adverts for roto rooter don't do much for me either. |
