I bought my home 6 months ago. When we moved in last summer, we didn't hear this sound. Now when I step on particular spot on this one bedroom, I hear metal flexing sound. I am guessing the duct is installed too closely to the floor.
I don't use forced air heating.
A few questions:
- Is there a way to eliminate or reduce the sound?
- Why didn't i hear this in the summer? This is very loud noise so if it was there, I must have heard it but it started happening in October. I live in Seattle where winter isn't too cold like in Michigan.
