Hello
I have a 3 story (not including basement) home. The second floor has 3 bedrooms and a bathroom, the 3rd floor is a finished attic. One of the bedrooms on the 2nd floor does not receive any air or heat through the vent. I've looked inside and cannot see anything blocking it, however I can only see what I can see from the bedroom. I've had an HVAC guy come look at it. He checked the dampers and looked into he vent from the bedroom as I did. He concluded there must be something blocking the ventilation to that room or the ducts may be crushed somewhere along the line.
My question, is there any way I can find out where that obstruction is? All of the other vents on that floor and in the house are fine.
Thanks
