Question: I am needing an air conditioner in the shop for the heat here in Houston. Are the portable air conditioners worth the money? Also, do they need to be vented to the outside?

they do need to be vented outside.
i installed a ceiling fan above my lathe. kit kinda just pushes the hot air around, but it least it's moving air.
 
Good question, I'm thinking about doing the same thing.

I saw one at Lowes that had a exhaust port that you could hook a 4" tube to and port the hot air outside.
 
Bill,
I posted a thread here about the same thing. I got one last week from my father-in-law for fathers day....( I have no children and have often wondered why I get a fathers day gift from him, but why fight it right?) He is sensitive and gets ticked when you return stuff, so I kept it. I was told I needed an 18,000 BTU unit. This is 12,000 and is truly inadequate. I saw one yesterday at Lowes just like it, it was their largest unit. I used it Sunday, it was 92 outdoors and the shop was kept at 83 all day. It did go up when I ran the DC and air cleaners...but it took the humidity out of the space, and was somewhat comfortable.

It comes with a 4 foot hose that needs to be vented to a window, and uses a DC type hose.
Again, it was free to me, and did help some..I am going continue to mess with it....

I decided to go with a window mount as my understanding is they are more efficient. If I had it to do over again, I would get wall mount hardware to go through the wall rather than take up window space. How large is the shop?
 
I use a 12'metal building , took some heavy canvas and split it in half , got a little ac in the window, it will keep the lower part coool but my head is about 1-2'from ceiling, It really makes a difference,last year i could not of dont anything without it, ,I use a big floor can and put aircondioner filters behind it to catch the little dust floating andit works

My shop is basically a 3 car garage. I would like the portability of the stand alones. I need something as it is just too dang hot even with fans, just blows hot air.

I have one of the portable units and vent outside through the 4" hose. For me it is worth it. Works best when you can position it near you so cold air is blowing on you. Only pain is you have to drain the water that accumulates inside the unit, but cool is better than hot and worth the minor inconvenience.
 
My 30x50 shop has a 12x16 turning room inside and I have a window a/c that vens into the big shop. no problems, keeps me super cool in hot summer days.......
 
I bought a window unit and mounted in through the wall at one end of my shop. Then mounted a box fan to the ceiling on the other side of the shop, blowing in the opposite direction from the AC. This sets up a circulation through the shop and keeps all areas pretty much the same temp. The shop is well insulated, including the garage door. Before this, the afternoons were unbearable, now I can work all day any day, no matter the outside temp.

yes they work great if you get the right size. they are actually more efficient than central are power wise. my wife keeps trying to get me to put one in my garage for the summer months.

I put one in my garage - I worked out there this weekend finally getting the power hooked up.

the garage is not insulated...yet...but the a/c did make a noticeable difference.

I think mine is 18,000 BTU
 
Morning here Bill,

I wondered if you use an air con in your workshop would you be continually clearing the filters from my experiences their is a fair bit of dust not collected.

What I have done cheap as a second hand barrell fan or Air Con Duct through fan, minor power cost, efficient air flow to outside vent through the roof with a suitable cover on the vent as my pic shows. I use this summer and winter as well, now our extemes are winter
bit below 30 degrees to summer 100,s.

Kind regards Peter.

When I was in Texas I had two of them. I would position one about 4' on each side of me when standing at the lathe or adjacent workbench. On 100+ days they worked OK but would never come close to cooling the entire shop and as mentioned above, taking out the water pan every few hours got to be a pain.

If I were ever in the same position again, I would opt for a larger window mounted unit that would cool the entire shop.

They are both sitting in my storage area now since I don't need A/C here. If anyone wants to come get them I can make a fantastic deal on them!

I have a 10x12 shop that is insulated. In the spring I install a small window AC in one of the window. I have had for about 4 years. On a 108F day a couple of summer ago it was 75F in the shop. Right it is 98 outside and 76 in the shop. Granted we don't have the humidity the rest of you have my $99 Home Depot AC make it nice out in the shop on hot days.
 
Not to steal this thread, but as mentioned I was told here I needed 18,000 unit and mine is 12,000 can I buy a 8 or 10,000 unit and it will work well?
Thanks
 
It looks like the window unit is the way to go. I can see both the positives and negs of the stand alones. Now, figure out where to put it. Got so much junk on the walls.
 
I have one in my basement. Now, being below ground, I think I break the BTU requirement for space. My recommendation is try it for a bit and see how it does. If it makes it bearable then you should be ok. But then 2 units can't hurt can it? I turn mine on about half an hour before I plan on playing and also turn on my air filter to make sure MOST of the airborn particles are gone to keep the filter clean.
