Duct design is one the most critical parts of the system, without the proper sized and installed duct system the equipment can not operate at peak performance, as a matter of fact undersized ducts are on the vast majority of houses out there. Rarely do we see a system moving all the airflow that it’s designed to do, which means that your energy efficiency drops.
The Air Conditioning Contractors of America (ACCA) have a book called Manual D, this book is everything about duct design. Its a technical manual covering all different kinds, sizes, turns, fittings, lengths, materials, velocities, friction rates, everything needed to design a system so that it can actually move the necessary air for its energy and comfort rating.
We can run tests on your system to determine if it is moving all the air it is designed for.
