However, just as ductless mini-split systems make it possible to customize temperature settings in individual rooms, HVAC zoning services allow homeowners with central HVAC to enjoy this level of convenience, too. HVAC dampers are an important part of HVAC zoning. What HVAC Dampers Are Dampers are crucial components of zoned HVAC systems.
