I don’t believe in global warming, but right now it is some bloody hot! I was turning some ash on the lathe and I realized I was soaking wet. AC units are cheap but I would have to cut thru cement block walls to install it. If I put any more fans in the doorways, I’ll get sucked right outside.

Take a look at a portable A/C unit. The heat duct is a flexible hose like a dryer vent that you run outside.

Look up Mini split. There are many brands and flavors, but they only require a small hole or 2 to get the refrigerant lines through.

This is my “comfort cart” I move to where ever I need it. I have a large fan (exaust) in a window at the rear of the shop and leave the door open to move the hot air away. New AC units do not need a drain line and milk jug to collect the condensation. For turning it is about 6’ behind me and the air stream through the shop (window & door) is behind that. Yeah when I need to tough up the grind I have to go to the hot side but it not for very long.

The heater works fine in the winter if I run the terpodo kerosene heater for about 15 minutes first to bring the shop up.

Lee you don’t have a location listed in your profile but if you use that cart and are at all happy with it I guarantee you are in a new year with a very dry climate. I suspect the majority of us are in a more humid environment and that would be a terrible idea. It is acting as a dehumidifier and you are getting a side effect of a small breeze of cool air. I am in south Georgia and can promise you my air-conditioner drips all the time as it is removing moisture from the air. And the way you have your cart set up it wouldn’t surprise me if your shop temperature actually nets an increase but as you said it is a comfort car and I have no doubt it does provide comfort

Yeah, I put in a portable unit. I am pretty happy with it. One small hole in the wall (~4” round), but it could have been vented through a window. It is a combination AC, heat pump, and dehumidifier.

Go with a mini split extremely efficient, 28 seer for mine, not terrible $ up front. Mine is a heat pump that is good to at least 10 below zero, and it has internet control for when I am heading home to the shop. There are many online suppliers if you can do it yourself. I bought my LG from supply house .com. Be sure to get a high efficiency rating, it will pay for itself. And do not oversize the unit, you will be cool, but damp.

please explain to me just how this AC cools with the exhaust in the shop :<))))

Looks to me like an interior heat pump, just moves the heat to the other side of the shop while blowing cool air. In winter, turn it around and move the cold to the other side while blowing warm air. If he is happy, that is great for him.

I am in Charlotte NC now but my first 27 years were spent in Valdosta; don’t get much more south GA than that without having one foot in FL. Here are the average humidity levels for morning & afternoon; GA 91M 54A, NC 87M 57A. https://www.currentresults.com/Weather/US/humidity-by-state-in-summer.php Glad to have it work as a dehumidifier when I am finishing.
My old one also dripped all the time and I had to run a drain tub from it to a milk jug on the bottom shelf. The new ac is drippless.
The other areas of the shop stay about the same as outside because the additional heat is pulled out with the large exaust fan.

I’m confident you’d be happier with performance and energy usage if it were mounted as intended though. They may just not be feasible in your situation. Carry on

Not used in the winter. In the winter I use the heater on the the bottom shelf. In summer the cool air from the AC falls and in the winter the heat (from heater) rises.
Works for me with my shop layout and what I do. May not work for anyone else.
Easy to relocate and used it last weekend with my Gson to make a display rack for his karate belts. Other than just a few minutes at the table and radial arm saw 95% of the time was at the workbench with the cool air blowing on us.

Y’all still have the rose festival? Mom wanted to go most every year (60’ -70’s).

Mounted as intended (window) it would do no good at all cooling a 16×30 uninsulated area. Does fine for the little 6X6 area I need for turning.

The portable units as Earl described may work better. This unit is dripless and was rated for a higher area (Sq F) than the portable for the same $$.

Ahh yeah like I said maybe not feasible for your space, 16×30 with no insulation I think you’ve got the best thing going

Yep still have the rose show which draws a crowd every year

I use a portable unit in my garage. I cut 2 holes in the garage door for intake and exhaust and installed exhaust ports like mechanics use to route a hose from the tailpipe through the door. Works great. The ports are a little smaller than the A/C hose so I had to adapt them using semi rigid dryer vent hose but it doesn’t seem to affect the A/C performance. I lay the drain hose in the slight gap between the door and the lip of the garage and it seeps under the door just fine. If you need to heat your shop too, I would look for one with a heating mode. It makes the shop usable year round but on particularly cold days I use a space heater. Also look for a unit that has 2 hoses. Mine does but I initially just vented the exhaust through the door and let the intake just pull air from the inside space and it pulls in so much air around the door that it definitely did not heat and cool as well. After adding the second port I also installed extra weather striping around the door to get an almost airtight seal. When I open the door into the house, the suction actually causes the garage door to move a bit.

Another option might be one of these Climate Right portable units that put the unit outside. You would still need 2 ports to pull and push air through but at least the noise is outside and you don’t have to sacrifice the space in the shop.

BTW, if you run any AC without venting the exhaust, you may be able to create a small zone of coolness where you point it but you will get a net increase of heat in the shop.

Thanks for all the great ideas. A portable unit makes sense. I do not need ” living room comfort” just cool enough to work in.
