New range hood question

1285 Views 5 Replies 3 Participants Last post by  jordy3738
Hey Gang,

We are going to install a new range hood in our kitchen. The ones we are looking at are about 600 cfm. It is likely more cfms that we need.

However, I have been told we don't want to rob our furnace of combustible air.

We have a high efficiency furnace. I thought most of the combustible air is brought in from the outside.

Do we still need to be concerned with this?

Should I just contact our local HVAC gurus?

Will do Chemist.


I am concerned that the range hood can pull enough air out of the home and take combustible air away from the furnace and/or hot water heater.

I don't know exactly what can occurs when that happens, but I think it leads to higher levels of carbon monoxide in the home.
