Air Duct and Attic Insulation Installation

Whole-Home Energy Control

Air Duct and Attic Insulation Installation in Chatsworth, CA

At ELM Insulation and Sound Solutions, we recently completed an air duct and attic insulation installation in Chatsworth. The homeowner was experiencing inconsistent temperatures, high energy use, and reduced HVAC efficiency due to aging ductwork and worn-out attic insulation.

Our team removed the old fiberglass batt insulation from the attic, installed new insulated air ducts, and upgraded the attic with fresh fiberglass batts to restore comfort, efficiency, and proper airflow throughout the home.

ELM Insulation and Sound Solutions did a fantastic job replacing our old ducts and attic insulation. The airflow is so much better now, and now the AC doesn’t run 24/7!

The Concern

The home’s existing air ducts and attic insulation were no longer performing effectively, allowing conditioned air to escape into the attic and making it difficult to maintain even temperatures in living spaces.

Old fiberglass batts had settled and thinned over time, reducing their insulating value. Combined with inefficient ductwork, this caused the HVAC system to work harder, leading to higher energy bills and noticeable hot and cold spots throughout the Chatsworth home.

The Solution

Our skilled crew began by removing the outdated fiberglass batt insulation from the attic to clear the space and prepare it for upgrades.

We then installed new air ducts with integrated insulation, ensuring airtight connections and proper thermal protection so conditioned air could move efficiently throughout the home without loss.

After the duct installation was complete, we installed new fiberglass batt insulation across the attic floor, restoring proper R-values and creating a strong thermal barrier between the living space and the attic.

This coordinated approach improved both airflow and insulation performance, allowing each system to support the other.

The Result

The new ducts and attic insulation immediately improved comfort and energy efficiency. The homeowner experienced more consistent indoor temperatures, improved airflow, and reduced strain on the HVAC system. Energy use dropped as the attic now helps retain conditioned air instead of letting it escape.
