Dampers are attached to the heating and cooling ducts in your home, and conditioned air is then distributed to different parts of the house as needed. This system is perfect for homes that have large open areas either in the floor plan or near the ceiling, such as a loft or atrium. It can be very expensive to heat or cool these large areas at all times, so having a system to switch off heating or cooling in these areas can save you money on your energy bill.If you're interested in determining whether a zoning system would be right for your San Antonio home, contact Chahat Enterprises Air Conditioning Repairing Services.
