Which is better round or square ductwork?

Round air ducts are best suited for high-pressure HVAC systems. Their design creates less friction, allowing air to flow easier throughout the building. Rectangular ducts aren't as efficient with their airflow, which means they can create more harm than good in a high-pressure system.

What shape of duct is most efficient?

Air Duct Shapes Round – typically the most efficient in transporting air. They utilize less material than rectangular ducts and still handle the same amount of air. Rectangular – these ducts are made to fit building construction.

What is the most common way of joining ductwork?

Ducts are commonly joined together by two means – the simple, anchoring Drive Cleat and the reinforcing connector. They are also used in combination, where desirable.

What are the three types of ducts?

Should ductwork joints be taped?

Parts of the air delivery system that also require sealing with tape include: duct joints, seams, junctions, and the area where the ductwork meets the air vent. The main trunk line is the primary delivery system for conditioned air and will require tape for the smaller duct lines that branch off of it.

Should you tape ductwork?

The whole purpose of sealing ductwork is to cut back on air leaks notorious for raising your energy bills. If you use duct tape on ducts, the savings will last only briefly. Once the tape fails, it no longer seals ductwork leaks and you lose heated and cooled air through these holes.

Is it better to undersize or oversize ductwork?

Oversized Ducts Larger than normal ducts are certainly capable of handling more airflow. But your HVAC system may not be equipped to pump that much air. In fact, your system needs a specific air pressure in the ductwork to properly distribute air.

What is the main problem with flex duct?

Too often, flex ducts are not installed properly, and they end up kinked, bunched up, undersized, or sagging. These issues can cause increased resistance in the duct system, resulting in too little airflow reaching a building's heating and cooling equipment.
