Nice and cool in my basement shop. Too bad I can’t spend some time in it. :\

Gerry, I am in the same boat as you… I live next door to you in MI and I have the same problem with my shop, the attic is not yet insulated. I have also found the shop temp to be even hotter then the outside. Even with the garage door open and fans going I just cant seem to cool it down in there… I have been toughing it out as best as I can but when its no fun being uncomfortable in the shop…

I live in NC and my shop is my unfinished two-car garage. Morning starts at 85F and I give up ten degress later in the afternoon. The biggest problem is sweat dripping on the cast iron of my tools.

Hot? not so sure I’d call it hot the complete opposite, a whopping 70 degrees in my shop and as some have already mentioned I have an AC in mine to grins big, 8K BTU window unit and I keep it on 70 for the simple fact that the DC is located in a seperate room outside the shop with a window port between shop and room for the wart, it draws the cold out and sucks heat in through the hidden cracks in the shop.

I considered putting AC into the new shop, but ruled it out. We get cool breezes off the bay, and our average daytime high temps in July (the warmest month of the year) is only 81 degrees.

Neighbor bought a new AC. The one he had purchased was too big for his window. He asked if I would mount the new AC in the window. In exchange he’d give me the one that wouldn’t fit.
So, I have this big honkin AC in a 24×24 shop. Cool as i want.

My shop is above the kitchen and is a secondary form of attic space with no insulation in the eves, 2 very tiny windows of which only 2 open and no insulation but lots of direct sunlight. The other day when it hit 98* here I tried going in the shop, I started sweating the moment I opened the door and was hit with a wave of heat. Half hour later my shirt was drenched and I was becoming dizzy from the heat. Had no choice but to give up, only thing I managed to do was make my first pen. Took three trips to the shop despite only taking a total of about an hour to make one.
The one upside is that the applewood I sliced up back in april that is stickered in my shop has to be practically dry with the last 2 weeks worth of heat.

It’s only been around 24degrees here so I don’t know how it is this summer but in previous years somehow the garage manages to keep itself cool. The insulation must work really good.
Now that I have those nice 20amp(All four equal 20) halogen lights in the shop, it might get a lot hotter. If so I have a wall air conditioner that with a little bit of work can be mounted.

I put a portable AC unit in my shop last week; the temps here have been in the high 20’s C, which compared to other parts of the country is not too bad. I like being cool though! As well, I live right on Lake Superior, so it gets very humid, I wanted the additional benefits of dehumidifying the shop with the AC.

Gerry, you mentioned that you thought about putting in an AC but ruled it out, why not go ahead and put it in? The ole saying it’s better to have it and not need it then to need it and not have it, what can it hurt? Put one in and only use it when you need it, you could also get one with a heat pump so as to knock out two birds.

Being here in Tx, AC is a must, we only have roughly 3 months of cold weather a season, though this year isn’t as bad as it was last year.

Randy—I ruled it out for 2 reasons … we only get a few days of high temperatures and humidity here every year, and I didn’t want to give up the wall space to accomodate a window/wall unit. Cost was also a factor.

I think once the insulation is installed, the shop will be a lot more livable during warmer months.

It hasnt been too bad in my shop. It’s mostly underground so it stays pretty nice as long as you dont open the main garage door and let the heat in. On the hottest and most humid days, it has been running in the low 80s. The shop is insullated too so that helps.

Uninsulated, OOOOLD detached 2 car garage in full sun all day with really old windows that do not open and only 1 door opens. It gets to be about 100 in there. This summer has been brutal in the North East. I really don’t care though. Heat doesn’t bother me when i am working outside. If I am trying to relax or socialize at a cookout or something, it really gets to me. I just stay well hydrated and plug away.

Bonus – some of my sympathetic baby weight gain is shedding off

Edit, b2rtch, I did the same thing all winter, No heat. Fortunately we also had a very mild winter here, and on average the temps were low to mid 40’s

My 7000BTU air conditioner and one of those floor fans mounted in the ceiling and I cah hold 76’-78’ inside, 102-104’ outside. Oh, and my garage door has 3/4” rigid foam in it, but the aluminum framing gets hot.

HA! 112-115 on average the last 2 weeks in the afternoons. I live in Phoenix and the afternoon sun hits my shop (garage). No insulation, no AC, just a fan. I typically do any work if I am working out there in the mornings when it’s only 85-90.

But basically this is my winter and I don’t do allot out there this time of year. So when you guys are complaining about the cold I am out there working away in the 70 degree shop :)

For my 20 X 28 shop I bought a portable 9K BTU AC unit at HD and hung it up on a wall about 6’ off the floor with the exhaust going into the attached uninsulated garage. My windows push out at the bottom so a conventional AC was not going to work. I’m in central MN and this past couple of weeks have been extreme for us so I decided to do something about it. If I go out to the shop in the morning and fire up the air it seems to stay ahead of the heat and makes it comfortable to work out there. I also run my ceiling hung air filter to move the air around.

my shop is in the finished basement of the add’n we put on the house 5 years ago… (and my wife still thinks I built it for her ;^)

without running any AC, it’s the most comfortable room in the house….

I just started running the dehumidifier on the other side of the basement every so often a few weeks ago, and that makes it even better.

about a 1 degree temp rise for every step up from the landing…

oh well…. I have to eat!

The way to keep cool in your shop is to have as much air circulation as possible. If you have A/c, that’s great, but with large shops, A/c can run up your electricity bill quickly. Insulation is the #1 way to keep cool; that and sealing air leaks. A pretty comfortable environment can be obtained with fans; not just one big fan, but several medium size fans, strategically placed to keep the air moving. My shop is 1200 sf. It has A/C, but I don’t use it because my insulation is not up to par and there ae too many leaks. I have a smaller 100 sf room that is my machine shop and I keep it cooled by A/C, due to the nature of the tools within. The room is kept cool with a 5500 btu A/C, which is more economical to operate than a 1-1/2 ton A/C. When I upgraded the A/C in my house, I used the old A/C unit in the shop. Until I get all the insulation work done, I rely on fans to keep cool. Temperatures here are usually 90° or more and humidity above 50%.

It’s been overcast and rainy for the last 2 weeks, but I have been sick as a dog too…

On the few occasions I have been able to get out to the shop, I have found the temps to be in the high 80s / low 90s. I kick the A/C on and the temp nosedives into the mid 70s quickly…

I am in the progress of a project to run a sub panel and finish insulating my shop. (insulation and radiant barrier in the ceiling, nothing in the walls, overhead doors have R10 ridgid foam with radiant barrier).

I figure when all is said and done, and this project is over, I will be able to enjoy a nice warm winter in my shop. I will likely have to wait until next May before I can tell if the AC will be able to keep up without running me into the poor house…

FWIW, we did something similar with a friends garage that he rigged for auto repair. About the same size as mine, but with 10’ ceilings. He has the exact same A/C as I do. 30 minutes to cool down to 72 degrees, and then it kids on for a few minutes every 45 minutes or so… Scary part will be the freezer in my shop. it WILL dump heat by the bucket out there… But it’s the trade off I agreed to in order to get my sub panel and insulation done… Likewise, she agrees, I need a shed to get all the lawn and garden, and, well non workshop stuff OUT. Maybe I can talk her into letting me put the freezer out in a shed too!

Before I insulated the shop doors and ceilings, in 90 degree weather the shop would REGULARLY get to around 120, and be basically unworkable. With just the doors and ceiling insulated, it rarely gets over 95 without the AC going. I expect to see uncooled high temps in the mid 80s when I get the insulation done…
