adding a vent to an unheated room


Hi there everyone,

i have a laundry room/mudroom which is unheated. I'm not sure why a vent was never put in this room, but there isn't one. I'm contemplating adding one since i do have water pipes in there (inside of an exterior wall).

It's easy enough to add the vent. my question is will adding this vent compromise the airflow or the way the system works? i don't really know anything about HVAC stuff.

not sure what info if any would be helpful, but here is some. my house is about 900 sq ft. 7 vents (1 in bed#1, 1 in bed #2, 1 in bed #3, 1 in bathroom, 1 in kitchen, 1 in dining, 1 in living room). i have 2 returns - 1 large 14x14ish and one small. not sure how long the main trunk is, but i'm guesstimating it to be 25'.

thanks for any input you can give.

Jamie

A small 4" to temper the mudroom should not cause any problems, as far as the ductwork.

Does the outside door have a good seal. If not. Replace it, so you don't blow conditioned air outside.

Why wasn't one you ask. That would be, because if a fire started in the dryer in the Laundry room, the smoke, and what comes with it, would be able to spread through the house quicker.

Lots of utility rooms with washer dryers have a supply in them. many also have a return.
