No heat from living room floor vents;

[nwirt74@gmail.com]

We’re getting heat from the bedroom and bathroom floor vents while using the gas furnace. No heat from the two living room floor vents. I checked the ductwork at the furnace and everything is attached? This happened to the bedroom vents before and I was able to reattach the ductwork to the plenum to the vents. I’m thinking that I am going to have to drop my coraplast to see where it has come loose?

I think you are on the right track, unfortunately. You may not have to remove much of it to find the separated duct.

ok, I had this same issue and found my vent line was collapsed under the floor.. I took it to a guy I knew who did RV HVAC and he reconstructed the vents. I'll post some pictures below of the before and after..
before:



and the finished line after:

Before the bedroom and bathroom vents would be blowing ALL of the hot air, with no air at all coming from the vents down stairs..

Now, you can't hold a match anywhere near those vents as it will blow out.

So I checked it out, the ductwork is connected on the furnace and it’s connected where it goes into the floor. So it’s disconnected somewhere between the vent adjacent to the kitchen island. I dropped my coraplast and I didn’t see any ductwork. It’s between the coach floor and the subfloor? Any ideas would be helpful? Thanks

go to a Harbor Freight and pick up a cheap scope on a flex cable... I think I paid $55.00 for mine... This tool will allow you to look into the ducts, remove the register closest to the front, mine was blocked between the kitchen and plenum which was about 6'.

Look into the ducts with the scope, you may have to shine a flashlight intuit as well.... I am NOT sure how my guy replaced it, I do know he did NOT drop the belly...

How did he access the area?

From the basement I THINK... He did NOT go from underneath due to the tanks being there... He is no longer in business as he retired and got a large boat and is on the water 12 months...
