I'm thinking of buying some sort of portable air conditioner/heater for an outdoor snake shed. I've been looking into this but none seem to have an automatic on/off system that will turn on the air conditioner at a certain temperature and turn on the heater when temperatures dip. They all either have timers or thermostats that do not go by degree of temperature. Since not all days are hot, I don't want to run an air conditioner on timer. All I need is to maintain a good ambient temperature for about 120 square feet. Any ideas on how I can do this?
