After pricing inverter generators large enough to run the AC. I had sticker shock to say the least.
My wife and I decided to go this route.
This size Champion generators are quieter than traditional open frame generators on their own. And with the addition of the sound deadening box. It is as quiet as my dads Honda whisper.
The box is made of 1/4" plywood, caulked seams, furnace filter material, and two electric fans to draw air for cooling.
I have found this combo to be a great way to save money on the generator, and have plenty of quiet power.
