Stay away from the outdoor units unless you live south of Dallas. I am just going to have to install the ****ing exhaust and intakes. BTW, gas is a LOT more powerful then the electric. Just check the manuals for how many gallons per minute they can heat, even a mid line gas kicks the shit out of a beast electric heater.
Hmm, I have installed many outside in Alaska and they have had I problem. They have internal frost protection that is good to -40 or so. You have to insulate the pipes or put heat tape on them but the unit will not freeze as long as it has power.
