So I am getting ready to start building my walk in cooler. I have two of the smaller (probably 5000 btu) AC units that my brother is giving me for the project. They are older units so by using two I won't lose total cooling if one goes down and I want the temps down around 36F so I figure also with two units going they will have an easier time maintaining temps.
My question is that it seems the easiest solution as far as temp control is the either get the AC thermostats outside the cooler or put a light bulb or similiar heat source on them to trick the AC into running and use a Johnson or similiar temp controller to turn the AC off and on as needed.
Is this right?
