A/C & Cooling
Depending upon where you live and how your house was built, your home may have any of several different types of home climate systems. Houses may be cooled by central air conditioning, room air conditioners, heat pumps, or a relatively old-fashioned way--with ceiling fans. And in some areas where too much or too little humidity is a problem, the interior air is brought into balance with the help of humidifiers or dehumidifiers. A good barrier of insulation helps maintain your home's energy.

Two important facts about heat movement: First, heat seeks a balance. Warm air always moves from a warm place to a colder one and vice versa; the greater the difference, the faster the flow of heat. Second, heated air rises. Unless it's stirred up, the air in a room tends to stratify--warm air gathers near the ceiling and cool air moves toward the floor. helps to keep hard-won heated or cooled air inside your home, where it belongs.
