You can accomplish this balance by ensuring the return flow has the same airflow capacity as the supply. You will also need to ensure every supply register has a route to a return register. To accomplish this, either include a return register in every room, or install wall and door grilles to supply a suitable route.
The Science Behind Duct Sizing
Upgrading existing duct systems includes thoroughly evaluating the current performance and identifying potential areas for improvement. Upgrades can encompass resizing ducts to better suit the system’s requirements, enhancing the insulation, or sealing any leaks to boost overall efficiency.

If your ductwork doesn’t already have them, consider installing manual or motorized dampers. These dampers can be used to fine-tune airflow in different parts of the building, helping to balance the system and improve comfort in each area. Things like air pressure, static pressure, the cubic feet per minute (CFM) that are moved through your ductwork...all of this should be different for you than it is for your neighbor. If a room lacks a return air duct, for example, it doesn’t matter how much cool air you pump into it during the summer. It’s going to struggle to stay cool, and will often be muggy and uncomfortable. At Home Performance Group, we continue to invest in technical training and up-to-date software so that we can correctly layout and accurately size our customer ductwork systems.
A Duct System Distributes Air Throughout Your Home

Setting these preferences at the beginning of your design process can prevent you from running into issues further into the drawing and quoting process.
Remember I mentioned earlier, all the diffuser neck size is 150mm (6″) and thus, all the flexible duct size is also 150mm (6″). After I went through the diffuser selection process, I decided to use 2-slot 1200mm (48″) linear diffusers with a neck size of 150mm (6″) for both the supply air and the return air. Once you got the HVAC unit, diffuser and grille sorted out, get ready a layout plan drawing or sketch it out. Your overall ducting size comes from combining the size, CFM, and friction loss of your home—meaning it ends up being a pretty complicated calculation. Because of this, HVAC professionals and amateurs alike typically don’t calculate the final HVAC ducting size by themselves.
Designing Ductwork Systems Doesn't Have to Be Hard
By addressing these issues, you can optimize the duct system for efficient performance. In order to design an efficient and reliable duct system, it is important to accurately calculate the requirements. This section will delve into the calculations and formulas used to determine the appropriate size and capacity of ductwork for different HVAC systems. Regular maintenance and proper sealing techniques are crucial to prevent leakage and maintain system efficiency.
If ductwork is installed properly, it is an efficient means of keeping you comfortable and regulating the temperature in your home. Aluminum tape is used to seal the seams between duct pieces, and insulation is used to separate the ductwork from areas such as attics or crawl spaces. Professional ductwork design services help maximize cost and energy savings. By designing an efficient duct system, they minimize energy losses, reduce utility costs, and optimize system performance. Additionally, their expertise ensures that the ductwork is properly sized and balanced, avoiding costly issues such as equipment inefficiency or premature wear and tear. Accurate air supply and return is critical for maintaining even air pressure throughout your home.

The high velocity in the main duct which is caused by the sharp turns and sudden bends, reduces the flow into the 3 branches on the left. We know all the values for this so we can calculate the mass flow rate (how many kilograms per second of air needs to enter the room). If we look at the calculation for room 1, we see it requires 0.26 kg/s.
Flexible ducts are typically made of a wire coil covered with a bendable, durable plastic, and surrounded by insulation. This type of ductwork is easy to install and can be useful in tight spaces where rigid ducts cannot fit. However, they should be installed with care to avoid kinks and bends, which can restrict airflow and reduce system efficiency.
However, this is obviously a very complicated measurement—and becomes all the more complicated depending upon the size and shape of your ducts. For this reason, it is usually best to leave friction loss rate calculations up to a professional contractor. But you can find a general number using an online friction loss calculator. My team and I at The AC Therapist are passionate about understanding the intricacies of ductwork design and are committed to ensuring that your system operates at its best. However, achieving this level of ductwork perfection requires more than just knowledge – it demands experience, precision, and a deep commitment to quality.
Proper air flow ensures that each room receives an adequate amount of conditioned air. To limit the noise in this section we’ll specify that it can only have a maximum velocity of 5m/s. We know that this duct also requires a volume flow rate of 0.79m3/s so we can use the velocity and volume flow rate to find the missing data. At the far end of the main duct the air is divided into two branches through a gentle, curved tee section.
Still, you should always at least consult with a knowledgeable professional when you’re designing an HVAC duct system. The size of your ductwork can massively alter the comfort of your home—and the amount you spend every month to keep your house heated or cooled. HVAC units represent the largest portion of your home’s energy use, so getting those numbers right is imperative in order to save the most money on utility bills. At The AC Therapist, we believe that every homeowner deserves a living space that is comfortable, efficient, and healthy. Our approach to ductwork design is centered on this belief, and we strive to offer solutions that are not only effective but sustainable and environmentally friendly. By choosing The AC Therapist for your ductwork design needs, you’re choosing a partner who is dedicated to enhancing the comfort and quality of your home.
