Star Energy maximizes airflow through your HVAC system by identifying leaks, holes, punctures, and damaged or disconnected ductwork. Over time, the consistent push and pull of an HVAC system turning on/off can cause your ductwork to become disconnected. Up to 30% of your building's heating and cooling energy is wasted through inefficient duct systems. Air can leak out of ducts at all the connections in the system. Leaks on the supply side of the system cause heated or cooled air to escape into ceilings or other unconditioned spaces. Finding and sealing leaks in your duct system can result in significant energy and cost savings, while also improving indoor comfort. Tighter ductwork means air is delivered where it is needed. Star Energy can inspect your ductwork and seal it at no cost to you.
