A Granada Hills homeowner contacted LA Air Dept after years of uneven cooling, high energy bills, and an HVAC inspection that revealed severely deteriorated fiberglass ductwork throughout the attic. The entire duct system needed to be replaced to restore comfort and efficiency.
LA Air Dept removed all original ductwork and installed a fully redesigned insulated flex duct system throughout the attic, restoring proper airflow to every room in the home.
The project was completed in two days, with the home's HVAC system tested and balanced before the crew left the property.

"The difference is night and day. Every room in the house is finally the same temperature and our AC bill dropped significantly the very first month."
Before any work began, our technicians performed an airflow analysis to identify the root causes of the imbalance. The new duct layout was designed to correct those issues, with all connections fully sealed and insulated for maximum efficiency.
