There is no one-size-fits-all with air conditioning comfort. Some people like the AC extra cold, while others prefer milder temperatures. The problem is easily solved when you install a zoning system, which let you vary temperature settings throughout the house. You can divide your home into two or four zoning areas, depending on the system you purchase. You no longer need to heat or cool unoccupied rooms, or change the setting to suit the needs of one family member.
