Manual D Duct Design
We map your floor plan and size every duct run. That prevents dead-end branches and high static pressure that make systems loud and uneven.
Ductwork Installation — Sacramento, CA
Adding central HVAC to a home with no ducts is a different job than replacing old ducts. Fresh Air designs and installs new duct systems for Sacramento homes from scratch.

Some Sacramento homes never had central heat or air. Others added a room and need duct extensions. Both jobs need a new duct design, not a patch to an old layout. Fresh Air starts with a Manual D duct design for your floor plan. We size each run for the load in that room. The result is a system with good airflow in every space, not just the rooms near the air handler.

If your home has never had central air, we design the full duct network from scratch. We work around existing structure to keep the job clean.
Adding a room? We extend the existing trunk or add a new branch sized for the added load. We test static pressure after the extension to confirm airflow balance.
A full central HVAC install with new ductwork in Sacramento runs roughly $10,000 to $19,000 for a 3-4 ton system. That range covers equipment, duct material, labor, and permit. Duct-only jobs for a room addition are smaller. We give you a line-item price at the free estimate so you see exactly what you are paying for.
