Air Conditoned Tent for Those Hot Months





Introduction: Air Conditoned Tent for Those Hot Months

Well for those who live in areas where it is almost impossible to tent camp during the hot part of the year this is should be a welcome cost efficient solution. Hot camping is no fun, epically in places where it does not cool down very much at night and is humid like Florida. So I was looking for ways to air condition my tent since I have a 5000btu window mounted air conditioner at my disposal. After looking I found 2 methods which look very promising. The AC Boot ( and this nice creation by Andrew Davis ( I decided to build something like the ac boot since I needed to travel light and didn't want to bring along all that ducting required for the second idea.

Step 1: Gather Materials

- 1 Tent (Cost: free hopefully)
- 5000 BTU Window Mounted Air Conditioner Arpox. (Cost Variable)
- 2 Yards of Ripstop Nylon which will be more than enough (Cost: Aprox. $14.00)
- 1 Bottle of Fabric Glue INSERT NAME OF GLUE HERE (Cost: $6-10)
- Bungee Cords (Cost: $3-5)

Note: Sundays a lot of the craft stores have 40% off coupons which can save you some money on the glue or fabric.


Step 2: General Plan

First measure the size of the air conditioner, and then apply this to the tent and ripstop fabric with a marker. Use spray on glue or Beacon fabric glue to apply the re enforcing fabric to the outside of the tent. Once done with outside the ducting part of the project needs to be created by measuring the size of the air conditioner unit and leaving a few extra inches on that end for easy fitment. On the other end the duct will need to fit the size of the hole which has been reinforced already and the duct will be adhered to the inside of the tent (see diagram below).

The black is where the hole will be for the ac, the white is the duct which is cut out to fit to the tent. The tent is the gray part while the red will be a piece of fabric like on the outside to reinforce over the top of the duct connection point.

EDIT: After using the unit sticking the A/C unit so it was in the tent was better than having the connecting tube, better flow of air.

Step 3: First Step

Clean the tent if it has been sitting around, the glue will work much better on a clean surface water and a rag will work good.

Then you need to select an area where you want to put the A/C unit, you need to take into account how high up the unit will be off the ground and not to have to cut through the lower tarp like moisture barrier. I have some simple diagrams below to help in choosing a proper location.

Measure the size of the A/C unit so that you can have it fit when you cut out your reinforcing material and the tube to connect the A/C.

Step 4: Trace and Cut Material

Apply the sizes which you took of the A/C unit to the ripstop fabric with a marker. Use spray on glue or Beacon FABRI-TAC glue to apply the re enforcing fabric to the outside of the tent. NOTE: its easier to collapse the tent and pull it taught so there are less wrinkles when gluing the fabric on, I used some heavy lead I had laying around. This reinforcement will help so when you cut the hole out of the tent it will not start to rip the tent (thus the name Ripstop)

Once the fabric is applied and the glue is set well you can cut out the tent material in the middle of the reinforcer.

Now you could put the Ac unit in the hole if the fit is right, Mine fit perfectly with small gaps around the bottom and it cooled off the tent very fast, the OAT (Outside Air Temperature) Was approx. 89 F and the inside was below 75F within 2 Minutes.

The next step we start to build the A/C tunnel.

Step 5: Creating the Connecting Tube

Ok so you need to measure the distance around the A/C unit at its longest points so the tunnel will fit around the unit without ripping. My Unit was About 64 Inches around, So i had about 66-70 inches for the circumference of the tunnel fabric. It is up to you for the length of the tunnel but longer will only make it easier to cut down or just fold over later. Mine was more than enough so I folded it back a few times to make it shorter.

Make sure when cutting and measuring the fabric for the tunnel to account for a few inches of overlap when you glue the tube together. 2 to 3 inches should be more than enough overlap to make a strong bond, press and make sure the glue does not bond to the bottom part of the tube.

Now you need to measure the 4 corners in the hole of the tent and apply them to the tunnel to make flaps to connect to the tent. I used about 3 to 4 inches of flap length to secure the tunnel to the tent.

Once everything is done you can use bungee cords to secure the tunnel to the A/C unit and then roll the tunnel up to fit better, the tunnel should be stretched so it does not sag and reduce air flow but do not pull too tight.

EDIT: Once again the tube could be shorter since I ended up having the actual A/C unit poking into the tent (see picture).

Step 6: Testing

Well i'm leaving for the Florida Keys tomorrow for 5 nights and last few times I was tent camping there over the summer it was hell at night sweating and waking up multiple times because of the humidity and the heat. So I will add pictures and info on how the tent held up.

Update, Back from Bahia Honda State park and it worked really great, ended up not using the tunnel like previously intended but the tunnel was more of a weather shroud which kept water out and cold air in. Condensation which drips out of the unit needs to be taken in account ours just dripped off the side which was next to the tent, it never got anything important wet. The A/C really made sleeping comfortable, it got pretty cold and turned the temp down a lot of the time, and it kept us in bed longer than we wanted to since it was so nice in there. But once the sun was directly on the tent in the afternoon it was impossible to cool down, so if you want to use it during the day I suggest getting a tarp over the tent which I saw a lot of others around us do. There were many other people who had Air Conditioners in their tent with duct tape. They used wood stands for their units like 2x4's and plywood any of those would seem fitting as long as the weight is not too far to one side.

I'm looking forward to tent camping in the summer again now, and I hope that this is helpful to some of you even though the summer is winding down already.

     When i first saw this I honestly thought it was a joke. I mean seriously,  un- environmental.
    If your hot open the doors!, or better yet just use the mosquito mesh without the fly
    never been to florida but i did spend 3 months in the amazon living in a hammock underneath a $2 tarp and slept like a baby. 

    We live in West Texas and go camping every summer where the daytime high is 120F and the nights get down to a chilly 80F. So yes, a/c is not optional if you plan on surviving the fun.

    Well not all of us are hippies that don't want to use power when we go on a trip, i wish that i could sleep in the high humidity and heat but its not fun.

    Haha, yea the 95% humidity and 105F weather can be kind of harsh with no A/C...

    I'm so glad you can do that and I could too when I was a lot younger but now in my mid fortys I dont tolerate the Alabama heat and humidity very well at all so in order for me to breath and be healthy I need AC and I have long ago fashioned one for my tent because I love to be outdoors and considering that my electricity comes from renewable energy I am quite green thanks to hydroelectricity but regardless of how the electricity is generated, I would choose being able to breath over smotheing in the humidity of the South!

    thanks I thought I was the only one thinking this was a crazy idea...

    was thinking why the tunnel version didn't work for the air flow. the front of the ac as 2 parts, the air intake at the bottom and air vents at the top. intake get the warm air in, and the top lets the cooled air out.. look into splitting the top and bottom in the tunnel itself... i'm thinking a box that fits over the intake at the bottom, with a flexible air duct (like a plastic coil tube for a dryers or bigger) comes out, and hang at the top to suck the hot air in... while the vent can just push the cool air out, as it doesn't get sucked back in the unit... OR the opposite, push the cool air at the top (make the vent for the output instead of input..).. just a tought...

    I followed your directions almost exactly and just spent a very enjoyable long weekend in Curray Hammock State Park (Marathon) in early September. I don't think I've ever slept so well in a tent in the Keys: thanks for posting such a great idea!!

    By the way, someone asked about portable units: they can be pretty expensive: I picked up a GE window a/c for less than $100 at Walmart. The ripstop and glue set me back another $50 or so. Plus, I don't really give up any interior space.

    Glad to hear how well it worked out for you, I havent used my setup since I first built it but I'm hoping to get down to the keys this summer again.

    Love the comments about the "Modern Day RV's"---we are looking to move into one in a few years and they are hysterical! What if I don't WANT an indoor/outdoor TV? Or a FIREPLACE??? Seriously! We would need--ROOM not frills. Plans now to buy older non-frill unit and re-hab.

    I too thought this was a funny but I remember the days of camping in tents and--it was NOT fun if it got hot n humid. Great idea!

    We have a floor AC unit and it does vent thru our houses LR vertical window---it comes with a panel or two for this--and it works really well even tho the entire front of the house gets full Eastern sun til late afternoon--then the entire BACK of the house gets---well you get the pic! The unit cost about $300 at Lowes this past summer. We have three asthmatics so this became a need---we also run two small window units in BR's. Our power bill has not gone up that much--and we pay a LOT for power in NY. It does work better if you keep an eye on the vent and there is a small drain that you need to keep an eye on too--but this is very minor compared to comfort and no ER bills for us!

    For those who are thinking of adding a window -house AC unit to an RV--or a pickup truck camper---some snooty campgrounds won't LET YOU IN with these. Just be aware and check in advance! They claim it is too "Low Class" for them.
