Five Principles of Good Duct Design

When it comes to your HVAC system, the ductwork plays an integral part in keeping your home comfortable year-round. It also has a significant role in your home’s overall energy efficiency. HVAC installation companies understand this, which is why they follow five important principles when it comes to effective duct design. Here’s a brief overview of what you need to know.

Load calculation. Each house is different, with its own unique heat gain and heat loss properties. When calculating your home’s heating and cooling load, there are many factors that come into play, including the number of inhabitants in your home, sun exposure and even your individual habits. 

Choosing the right system. The design and size of your ductwork is determined by your HVAC system, as well as other related equipment.

Duct insulation. Air conditioning and furnace installation companies position ducts in a home’s conditioned spaces. If the ducts have to pass through areas that aren’t conditioned (such as attics and crawl spaces), they should be properly insulated.

Clear pathways. To maintain a neutral air balance in all the rooms in your house, it’s important for each room to have its own supply duct and dedicated return duct. If a dedicated return duct isn’t workable, a central return in a hallway or other common area is the best alternative. 

Sealing and testing. Each segment of your ductwork should be sealed and tested before being permanently connected to your HVAC equipment.
