- Do-It-Yourself (DIY) air conditioner for my airplane using an ice-chest, small radiator, bilge fan, and wireless remote control. Also shows a custom power source that is separate from the aircraft's electrical system. The video has several sections:
1) Quick Description of the Problem Being Solved
2) Summary of the Usual Options
3) Photos and Summary Description of My Solution
4) Step-by-step build sequence followed, including parts, prices, and sources.
Enjoy!

I built one exactly like yours then made a couple of modifications you may find useful. 1) Put your fan inside the cooler. Knocks down the noise by at least 10 db. 2) Separate the water from the ice. I have a large aluminum bowl that sits in the ice with a lid and 50 feet of hose coiled up also in the ice. I put the pump in the bowl drill two holes in the bowl, stick the hose through the bowl and include the radiator in the tube loop. Yea put water in the bowl. It gets just as cold and the Ice, without the water current, keeps at least 30% longer. 3) Insulation blanket over the ice will keep it away from the air current which also melts the Ice faster.
If you buy into the closed loop water pumping system you can also use gallon milk jugs filled with salt water and approximately 5 feet of tubing stuffed inside (a pain but worth it). Drill holes in the cap and added tubing connectors and freeze them. Hook your milk jugs together and you will saves a tone of money on ice. If you do milk jugs make sure you get all the water out of the tubes before freezing or use food grade glycol as an antifreeze.
Great video. I just watched a similar video by Make Everything. The major difference is that he used a piece of foam to separate the air compartment from the ice compartment. If I were building one, I would definitely do that. If you can put the ice chest on a stand to raise it up, you can shorten your air duct. The shorter the duct, the cooler the air. I appreciate your details with pictures and part numbers. Very helpful!
thank you so much for the effort for putting this video all together, amazing job. I'm wondering how the cooler worked at the end?, and if it is efficient ?
Very nice build and great narration on how it was constructed. I plan on making a portable unit like this with the trans oil cooler as well. Thanks for sharing your idea much appreciated.
Awesome. Looking to make this for our sailboat for these hot Texas summer nights when at anchor.
That is great. Do you have temps of cabin vs outside or delta temp from inside to out? Look forward to your test results.
Thanks for the great DIY. Maybe i missed it but how long a run time do you get ie. battery and ice time of actual use?
This was so cool to know love your voice
Thanks for sharing 👍
Hi Ron - can you do a video or just post the results on if it made much of a difference? Did you adjust/change anything now that you have used it for a while?
It works great…really makes it bearable to fly here in Phoenix in the summer. Didn’t change anything since the video.
PSS. You left off the type of charger that you used. and then again, I would think you used a standard 12v/24v battery charger, or was it a Trickle charger, while the air conditioning unit was on.
Nice video and well presented with lots of detail. What is the total weight of the system when filled with ice? Is it possible to put a variable speed control on the fan?
What do you think about the idea of using an electric cooler that can be set to 0 or even -7? Seems it would avoid the ice melt restrictions and just keep water in the bottom.
I suspect the volume of cold air is very limited. It's all a matter of getting enough volume of cold air into the cabin.
Great video. Question, wouldn’t you want the radiator to be isolated from the iced air in order to prevent humid air from entering the cabin? Maybe mount the radiator on the outside of the lid? Then the only reason for the protective grates would be to keep fingers out of the fan.
I could be wrong, but as long as the water is colder than the air passing over it, the water *shouldn't* evaporate into the air and will instead collect condensation from the air.
Excellent !!! Thanks for sharing... .
It's a cool build, very detailed video. How much was the total of all the parts used? Also curious to know how much temp you lose from the cooler to the end of the tubing. It looks like a six foot run, so hopefully not that much.
Thanks Bill. Approximate total cost was a few hundred dollars. It's less than a six foot run, and there's not much temperature drop at all.
How did you wire the switches? I need to wire from the power source to the switch and also a speed control and pump. My brain is fried
Here's what I did: 1) Ran power and ground from aircraft battery to cooler (battery is behind baggage area in my plan)....used a quick connect/disconnect, 2) Bought a high-amperage (20A I think) power switch box with wireless remote. Wired that per the instructions that came with the switch, 3) split the outgoing power from the switch box to two toggle switches on the cooler (one switch for the fan, one for the pump). So basically the switch box sends power to both toggles - always. The wireless remote turns on/off power to everything re. the cooler. But when on the ground and wanting to drain the water out of the cooler, the two toggle switches let me turn on the pump while keeping the fan off. Hope this helps.
Oh, and I don't have a speed control for the fan or the pump....both are either just on or off.
Nice job Ron, check out this build for the airplane, dont any of the ships power and dont need a battery box etc. utube The BEST DIY Off Grid Air Conditioner-Super
This was just an excuse to brag about your aeroplane 😆
Painful to watch
