can i just bring in cold air from outside rather then running an ac unit?

a timer would work if it matches the load settings of the a/c if not it will just burn out the timer or maybe worse fire so be sure to use a neavy dutty timer like the one on your hps light.

its just a timer that has a thermostat on it.i would think that it would work fine with an a.c. unit. im just using a normal timer 4 now,but b-4 winter hits,ill be using one with a thermostat on it. (andy) you get them thermostat timers right by the duct fans and stuff at home depot or menards.theyre like 30 bucks.the same one Timefortokin posted.
