I have concerns about replacing fresh air to my central forced air furnace after installing exhaust fan system
Renovated the basement in my bungalow (1425 sqft). I have installed an exhaust system in the basement that has 4 vent diffusers (2 in games room, 2 in the home theater) this is powered by an inline exhaust fan (438 cfm) and ducted to the exterior of the house with 6″ ductwork.
My concern is am I removing too much air from the house and impacting the combustion air required for the furnace? There is a 6″ freshair intake to the return air of the furnace and the house is 35 years old and has typical “natural leakage”. Should I upgrade the intake (bring in more) or am I worring over a marginal amount of air loss.
