1 Do & Don'ts of Duct Fittings

In this video we will go into depth about why your duct fitting choices matter. We will cover the two things inside your ducts that make the blower push against more pressure, thus reducing air flow or increasing energy use, depending on blower type. They cut the amount of air that is delivered to the rooms. And they can be reduced but not eliminated. Do you know what they are? We will cover the types of fittings you should use, some tips on making the air in the ducts flow easier, why you shouldn’t use dead head and Bullhead tees, why you shouldn’t tie in your return drops in a square throat manner, and more. Also, there is an actual laboratory air flow demonstration video that shows air flowing through ducts and how certain types of fitting either pass air well or restrict it.
