We are remodeling our 70 year old home. We want to move a door way
Over 6 feet, the problem is the cold air duct is located where we need to
Put the door. After the door way is opened up & the duct is located can
We use a floor grate instead of the standard wall opening for the cold air
Duct? We actually like the idea of using a floor grate as it would definitely
Look like it belongs in our home. If so is this a safe alternative?

Thanks

I worked as furnace installer and can tell you a few simple rules about it

When heat ducts are installed, they are placed by the windows

The return air usually is on inside wall as is the thermostat

Warning: Some older ducts have asbestos insulation and,,

Require special handling, government regulations!!

Even though our house is 70 yrs old the furnace was replaced
About 15years ago. So asbestos is not a problem. Can we
Install a floor grate for the cold air duct grating. I know the usaul
Is a wall grate for the cold air return, But that would be a problem
So I need to know if it is feasible to put a floor grate instead of the
Wall grating?

They were quite common in older homes as you mentioned. You may need to look a little to find a big enough one.
