I inspected a house on Wednesday and the gas furnace was located in the garage. I wrote this up as being a safety hazard because the furnace could draw carbon monoxide into the house via the fan cabinet and around the filter. Was I correct.

Gas furnaces are quite commonly located in garages. If the units distribution system is sealed properly, there is no danger of mixing conditioned air with “garage” air.

Hello,

What about leaks where the filter is inserted into the furnace and around the access door to the blower cabinet. I know with my furnace, there is a gap between the filter and the edge of the slot.

Thanks for the info.

Your right John. In my area the unit can not be in a garage unless it has been put into a separate enclosed area (with a fresh air source of course) and the door must be properly weather stripped. icon_smile.gif
