Is the fan in the garage or is this vent on the exterior of the garage?

Why was this done in a wall at all. Venting works best when it takes care of the fumes that rise to the ceiling.

The fan is in the garage and the vent on the exterior of the house. We just wanted to have a fan for the heat to escape, no fumes. The vent is also rectangular not square.....therefore covering a portion of the fan blades. I’m not understandong why he didn’t cut more drywall and move the fan up for better placement. This is so frustrating.

No it’s not just you millworkman. It’s a very poor attempt at an installation. There is so much wrong with this. I am in the process of canceling this install and finding a more qualified company.

Drywall is not an exterior product at all. Falls apart when it gets wet. Why is that even there then?

That picture is from the outside looking in. The drywall you see through the vent is on the inside of the garage.

It’s not confusing; I see exactly what they did...I think. They cut out a section of drywall between two studs and plopped a fan over it. And now the wall cavity is open to the elements because they did not frame the opening nor did they take any measures to weatherproof the opening. The opening should have been treated like a window or door opening and properly finished. Also, that grille (and probably the fan) is the wrong product for that application.

FWIW, even if they do a perfect install, I don’t see you getting the benefit from this setup that you’re looking for. Are there supply openings somewhere? What climate is this?

I would like to the statement of work the installer used.

I would like to see The OP’s instructions to the installer.

I think the OP hired a Home Depot parking lot quality guy, and the OP did not do due diligence.

Sammy you are 100% right. I had the fan removed and plywood put over the opening until I make other arrangements with a different company. He also did not put an intake vent on the other side as promised during the consultation. The climate is hot....Arizona.

What’s above the garage? If there’s attic space, you could install the fan (not this fan) there and exhaust the hot air through the roof. There’s a specific product/system I’m thinking of that I believe has a network of “certified” installers. But, like I said before, I’m not sure you’re going to end up with a cooler garage since the air you’re pulling in to the garage is 100° +.

That grill looks like it is meant for interior installation, not exterior. But I see that you have put a halt to the project.

I think the whole concept needs a re-think anyway.

It’s a two story house, so no attic above the garage Sammy. The concept/idea ci_lantro is to keep air circulating and continue running the fan to cool the garage through the night. The heat stays in the garage all night right now unless you leave the garage door open a few inches, which I prefer not to do. If the fan keep air moving and cools the garage down in the evening/at night then I would be happy.

Oh--so no attic above the garage. Yes, I understand wanting to get the heat out. Used to live in western OK--it gets HOT there too.

I was thinking on the order of a passive system...a large intake near the floor, preferably on the side of prevailing breeze and a gable vent/ cupola--which won't work for you.

Maybe something like a shutter fan mounted close to the ceiling & w/ adequate air intake near the floor?

They come in a lot of sizes, different CFM's and are relatively inexpensive.
