    Arrow Putting a fan in a garage vent

    Hello everyone.. noobie here... I have a question.. Iíve been trying to cool off my garage for a while now.. a lot of HVAC companies told me thereís no way to add any more ducts to the 1st story of my house (2 story house).. so I was thinking if there was any alternatives I could do with this vent? A fan/some type of cooler? (not trying to spend a lot of $$) I donít know if itís considered a crawl space vent because it goes directly into my garage (no crawl space in my home that Iím aware of except the attic) Iíve researched foundation vent fans and crawl spaces ventilations but Iím not sure what exactly to look for.. thanks for any help I appreciate it a lot! 👍 sorry if the pics are bad uploading and typing from my phone!

    Is the space insulated? If not I would start there. A fan might not be able to overcome the load from the walls and roof.
    A fan won't introduce anything but hot outside air and the possibility of drawing cool air from the house. If a fan is used I would blow into the space rather than try to draw the hot air out.
    Big box stores here rent machines that blow insulation into the walls. They work ok and are better than nothing.
    Give me a relay with big enough contacts, and I'll run the world!

    You can be anything you want......As long as you don't suck at it.

    If a person wants to create a machine that will be more likely to fail...Make it complicated.

    I think the walls are insulated not 100% though..as far as the airflow goes the only airflow it gets really is when I open the garage door (maybe once a week) and the foundation vents.. I was actually thinking about placing a fan (in the foundation vent) to blow the outside air in garage.. I know it would probably be cold air at night and hot air during the day.. but it would most likely be better than it is now because during the summer days it tends to be hotter in the garage than it is outdoors.. I just donít know what kind of fan/device to really look for.. the only thing I came across that was similar was the crawl space ventilation fan.. but Iím not sure if that would work being that itís intended to blow the hot air out I believe right?

    It looks like a good idea.

    I am not sure it is legal or safe to install a vent or connecting duct from the house to the garage.
