furnace noise

debd

Our garage was converted into a living room. The furnace is in here and a closet was built around it . It all looks very nice but the furnace is noisy. We can insulate the solid walls behind and to the side, but is there anyway to insulate the door. Its an accordion slatted door.

I will go ahead and say no. The reason for the slant door is for the furnace and water heater to to get air. The only way to sound proof the door would be to get a solid door but that would suffocate the furnace and water heater. Over here where I live you have to have a slant door or large slant covers on the wall going to the room. Sorry you might be S O L on this one unless someone else can chime in with a idea and let me know I'm wrong.

Can you install vents or louvers to the outside to give the furnace its air?

This would kill two birds with one stone: reduce noise, and not exhaust heated (interior) air to the outside as the furnace runs.

The louvered door would then be replaced wiht an insulated door.

The furnace is against an inside wall so the only place to put the vent would be through the attack and roof (which seems like a lot of work) or through the floor and vent it into the crawl space. Would this be a problem and how big would the vent have to be?

Might be best to ask on the HVAC forum. There are probably some pros there that can give a definitive answer....
