Cooling With Window Unit and Gas Generator

Although the hot weather is winding down, it's still really hot some places (like Laredo where I'm at right now) and I thought I would give some specific information about using a gas generator and window unit to stay cool.

I use a Honda EU2000i 2000 watt generator, which can be found for $859 (shipping included) on the internet. Mayberry's is where I got mine. This generator is VERY solid and those of you who have them know what I'm talking about. It is also compact and quiet. Its gas tank holds a little over a gallon, which will run a 5,000 btu window unit for about 9 hours. This should answer a big question about whether the generator will run the A/C for an entire night and it will.

5,000 btu window units can be found lots of places (Walmart, Home Depot). They cost about $80. While you're at Home Depot, look in the trash can section and you will see a blue plastic recycling bin. These bins make nice travelling containers for the small window units. The bin also keeps any water in the air conditioner from making a mess when you are putting it away.

Use the passenger window. I secure my window unit with rubber straps using my mirror bars. I use Reflectix material around the unit to seal the cool air in/hot air out.

Get an air conditioner extension cord. They are about 8 to 10 feet long and make the setup easier to use. Use duct tape to permanently attach the extension cord to the window unit's cord. Get a combination cable bicycle lock and lock the generator to your truck. You will need to put the generator outside while using it since it is air cooled.

I got a fancy 5 gallon safety can, DOT approved, very high tech. Unfortunately, it's heavy and I don't like carrying it around, so I got a 2.5 gallon plastic can that I like a lot. I can walk over to the gas islands and fill it up and it will let me run the generator for 2 to 3 days. Not a big hassle. Look into the rules regarding transporting gasoline. This is not a big deal, but be aware of the issues.

Cool your truck down with the truck's A/C before turning on the window unit. This works well. A small fan inside the truck is needed to get the cool air into the sleeper.

This setup is not perfect and it is a little bit of a hassle, but it's not a big hassle. The total cost is under $1,000 and the system is portable and servicing it is no problem at all. If the A/C breaks just buy another one. The Honda generator is very reliable. I think it is an appealing alternative to the $5,000 to $10,000 setups that still seem to have many frustrations built into them.

The Honda generator also has a battery charging output and cable, which is handy if you ever have dead batteries. The Honda will also power the block heater on your truck.

Sounds like a workable idea. I spent $2500.00 for a gas generator installation. 4000w Generac, located in an under hung storage box.
Didn't use it for a/c, but kept the batteries charged and the block hearter working. It was was all wired to the inside of the cab, and started from the cab.

Had many problems,(overheating, caught on fire once, unit was in the repair shop once); By the time we had all the probs worked out it crapped out again. And now it is stored in the garage, and after it is fixed again, we'll probably only use it for the house.

Your setup sound much more simplified, and if I was to do it all over again, thats probably the route I would take. After all, I now have an empty box to store it all in...
