Please note, there is a known issue with this site caused by setting both the heating system and the cooling systems to none. A temporary work-around is to enter a minimum system in either category, then ignore the specific energy/cost adjustment. For example, you could enter a room air conditioner and disregard that category when you receive the results customized for your home.
