The Hidden Key to Efficiency

Your AC and furnace are only as good as the ductwork connected to them. In many High Desert homes, old, leaky, or crushed ducts are responsible for up to 30% of energy loss. This means you are paying to cool your attic, not your living room.

Our Duct Services

Duct Repair & Sealing

We locate leaks and seal them with professional mastic or tape. We also repair crushed or disconnected runs that restrict airflow.

Full System Replacement

If your ducts are over 20 years old, the insulation may be crumbling. We design and install brand new, properly sized R-8 duct systems for maximum airflow.

Airflow Balancing

Fix hot and cold spots by installing dampers and properly sizing your registers to ensure every room gets the right amount of air.

Ductwork FAQs

How much does duct replacement cost?

It depends on the size of your home and the accessibility of your attic. We provide free estimates to give you an exact price.

Can you clean my old ducts?

We can clean them if they are structurally sound. However, if the inner liner is torn or brittle, replacement is the better option to prevent fiberglass from entering your air.

What is R-8 insulation?

R-8 is the current California standard for duct insulation value. It resists heat transfer much better than the older R-4 or R-6 ducts found in many AV homes.
