Duct assemblies are like pipes for plumbing, and veins and arteries for our circulatory system. Their function is to convey the air for HVAC systems. Duct’s are made of different materials according to their function in a given design. Galvanized metal, aluminum and sheet metal are common materials found in the commercial sector, while fiberglass panels and flexible ducts are more present in residential premises.

Duct design is maybe the most important part when designing an HVAC system. Many factors are to be taken into consideration and calculations made to efficiently move the amount of air needed to obtain a properly balanced and confortable environment.

The importance of air is extremely undervalued when designing and troubleshooting a system. Air pressure, speed, weight, and volume are factors that need to be properly balanced, and once the air exits the air handler unit, it is the ductwork responsibility to handle them. A common issue found is a broken section of duct in a ceiling, which unbalance the whole system resulting in high electric bills, rooms cooler than other ones, high humidity and allergies.

Please contact us if you are experiencing higher electric bills than usual, rooms difficult to cool or heat, often sneezing or running nose, musty or stale odor; all these are symptoms and signs of a possible duct issue.
