How does the Duct Design Serivce Work?

We use the Professional Standards set by the ACCA Manual D HVAC Duct Design Criteria. ACCA is the Air Conditioning Contractors of America. They are responsible for setting and maintaining most of the quality and design standards established for HVAC contractors across the country.

The Manual D Design criteria are the only recognized standards for duct design in the US.

First, your duct layout design expert will work from a drawing of your home that you provide. Then he/she will calculate the individual air requirements of every room in your home using custom industry formulations that ensure comfortable and balanced air delivery throughout your home.

Special attention is given to rooms with large window areas and other points in your home that have lacked proper airflow.

Next, he/she will formulate a view of the duct system as it will look when completed, including main trunk lines, transition points, and ducts to each room.

Then, we will review the layout with you to ensure that it will fit all aspects of your home and answer any questions you may have.

Simply follow this "map" of your duct system to complete the installation and you're done!

Please allow 48-72 hours to complete the service. You'll receive a copy of the preliminary layout for final review and any questions you have can be answered at that time.

Hot and cold spots are a thing of the past when you have your system custom engineered by AC Direct.
