Paying for HVAC zoning in your home is a great way to lower your spending on energy. In many households, HVAC use accounts for nearly half of the monthly energy bill. With zoning, heating and cooling systems are streamlined to only deliver conditioned air where it’s needed. HVAC zoning is far cheaper than paying to heat or cool an entire home uniformly. Moreover, it doesn’t require a major overhaul of your existing ductwork or the installation of a brand-new heating and cooling equipment. Instead, much of this upgrade will be accomplished through the installation of HVAC dampers.
HVAC Dampers Section Your Ductwork Off
When residential HVAC systems are zoned, dampers are installed at various intervals throughout the ductwork. Dampers section duct systems off to create individual service areas or zones. Dampers open to allow air delivery and close to inhibit it. When a single zone or room reaches the desired temperature, dampers to this space will seal shut, and conditioned air will be routed solely to those areas that require it.
Bypass Dampers Prevent the Build-up of Air Pressure
Using HVAC dampers to create separate service areas in homes with central HVAC systems is not the same as closing individual air vents in unused rooms. While professionally zoned HVAC systems provide a higher level of efficiency, closed vents do not. Instead, closed vents cause air pressure to build within HVAC ductwork. This puts undue stress on heating and cooling equipment, lowers its lifespan, and ultimately increases home energy bills.
HVAC dampening systems are designed to prevent this from happening. When zoning homes for customized comfort, HVAC technicians install bypass ducts and bypass dampers. When too much air starts building in ducts, bypass dampers open so that excess air can escape. This is a common air pressure relief technique in homes that have their HVAC systems zoned post-construction. If HVAC zoning is completed during the actual construction of a home, oversize ducts can be used for air pressure relief instead.
The System’s Comfort Control Box Tells Dampers What to Do
In zoned residential HVAC systems, dampers are always automated. These components are opened and closed according to the commands issued by the system’s control box. Also referred to as a comfort control box, this unit determines how much heating or cooling is needed in each zone or area throughout the home. It then opens or closes dampers as required. It also leverages bypass dampers to provide air pressure relief whenever excess air pressure exists.
