When the house was built, I opted to insulate my attached garage. It paid off during the winter. With no climate control, the space stayed well above freezing. But during the summer it is kicking my butt. I don't like leaving the doors open since it invites insects and debris in to work their way into the house. I have come out in the morning to find the garage still holding 90+ degrees when the outside temps are down around 70.

There are windows on the one end of the garage (it is a side entry garage, so the windows are on the "front" of the house/garage elevation). I also have a pull down attic access and have played around with leaving that open to allow heat to rise up through natural convection. I have tried only opening the windows (and attic access) after the sun goes down to try to flow the cooler air through. I have tried leaving them all open all of the time.

My 2 main concerns with the heat in the garage are:

1- Heat load against the house. Although the walls between the garage are well insulated, it is clearly counterproductive to have a hot box attached to an air conditioned house.
2- I have our spare fridge/freezer in the garage and store other dry goods out there. Keeping these items at 85-100 degrees all summer is not a good idea.

My secondary concern is that I do occasionally get to work on a project in the garage. Right now, I grab tools and run outside where it is cooler (day or night).

And yes, this is a small issue. But I have seen you all offer some very good input to other trivial topics so I thought I would see what you think.

Thanks,

Lee

Try a mini split heat pump,heat in the winter air con in the summer very well suited for your climate as it works off the outside inside heat curve differential.And they are ductless and cheep and easy to install.

A Whole House Fan, installed in the garage. Easy, cheap and really effective.

Canadian Kook - I would love the heat pump option. But I forgot to mention how cheap I am. :lol: Initial investment is one thing, paying to run it is another challenge!

Gizmo- I was wondering about a whole house fan. I have to do some learning on that. Where would it vent to? I assume I put in the ceiling of the garage, but how does it vent outside? I was also considering an attic fan in the garage attic. But honestly, I don't want to look at it on the front view of the house. The garage attic has ridge and soffit vent but nothing forced at this moment.

It's my understanding that the whole house fan forces the "hot" air into the attic and the air escapes through the roof and soffit vents. I've also thought about an attic fan as a way to cool the attic of our house after the heat of the day has gone.

I'm also very interested in this topic as I have the same issue with my garage. In the winter we have a 220 heater that keeps things in the mid to upper 40's when we just park there, but can easily heat it to 70 in an hour or so. As for cooling I've looked at an A/C unit and also various shop cooling methods. A "swamp" cooler being one. In a completely neck fashion I took an old garden hose and added it to a box fan in an effort to see what kind of difference a red neck mister would make. It did help, but also made things around it damp. Not really that safe either. With our high humidity it also looses some of it's effectiveness. With 2 box fans and the doors open it wasn't bad in there. Once the doors closed and the fans were turned off it got hot quickly....

I definitely like the idea of something that is thermostatically controlled. I would have to find a small one due to the limited amount of ridge and soffit vents as part of the area over the garage is actually living space. Doing a quick search, they seem to start in the $200-$300 range plus the price of the vent cover (louvers) for the ceiling.

Definitely has my gears turning.

To remove heat is easy simply try an over size cfm bathroom fan and duct it to the attic and out ...insall the bathroom fan at floor level to recover heat also install one at ceiling level off an other switch and vent it to floor level.Cheap Cheap

Jason (dieselshadow) just installed a mini-split in his garage, maybe he can advise on how much it cost's to run...

Have you even seen the screen doors for your garage door? Let in lots of air and keep the bugs out. Depending on your area could even leave it open all night.

Here's a link to the install thread over on Workshop Addict. So far it's close to about $10 a month to keep my garage at a constant 70. I don't turn it off. It's too efficient to not use it 24/7. My master suite which is above my garage is noticeably more comfortable as well. :thumbup1gif: A bit more expensive up front, but well worth it. My garage is very comfortable to work in now. Both the indoor and outdoor units are super quiet. I highly recommend it. :good2:

Boy I'd like to look at that but I cannot see the pictures, just registered.
Never mind I had an "rgd" moment there.

The pics work for me. You should be able to see them as a guest as well. Did rgd set you up for failure? :mocking:

My first question is whether or not you put a ridge vent on the roof to let the warm air vent out ? My other suggestion would be for an attic ventilation fan or something similar.

That was a GREAT read!

This is a good thread. I wouldn't mind cooling down my garage but not at a monthly expense. I have heated floors so the garage is really nice about 80% of the year. But when the temps are 100 degrees like right now its warm. I have ridge vents throughout and an attic hatch in garage. Thinking an attic fan that replaces hatch cover might help !!

I too am happy to see all of the feedback here. I would love to heat/cool the space but also can't justify the expense right now. DieselShadow, do you open the garage door often in your space? With us taking 2 cars in and out twice per day (plus taking the dog out the service door) I suspect I would not get by with $10 per month. It also appears as though your space is partially below grade. All of mine is above grade. My only saving grace is the portion of wall that is attached to the house and a portion of the ceiling that has living space above.

RRMCCABE, with ridge and soffit vents, I was hoping that having that attic access open would give me some convection relief. Not so lucky. With this discussion, I was leaning towards trying to find a huge bathroom fan or a small whole house fan and cutting another whole in the ceiling. But you make an interesting point. I could leave the attic stairs down and put a drop in fan into that opening. Then in the winter, just put that fan off to the side up in the attic and close the stairs.

Thanks again for all of the input guys.

Lee
