How Faulty Ductwork Affects Your HVAC System

When most people think about heating and cooling in their homes, they are only thinking about the equipment that they can actually see. Oftentimes the ductwork is overlooked due to being hidden out of sight. This can be an expensive mistake!

Ductwork is the tubing that circulates the air through your home. It allows the air from inside to be pulled through the return and is also the pathway that brings conditioned air into your rooms. If your duct system is faulty, your HVAC system is working harder than normal which leads to high electric bills and premature breakdowns of your equipment. The three main types of failures we see are poor duct design, leaking ducts, and ducts that have been crushed or torn.

Types of Ductwork Problems

Poor design: If your ductwork is not sized correctly, you could feel the effects in many different ways. You may have rooms that are too hot or too cold, vibrating or rattling noises from the duct, and high energy bills.

Leaky ducts: Ductwork, like anything else, can deteriorate over time. Small cracks form that allow the conditioned air to escape into your attic or crawlspace. Also, the insulation on your ducts lose their R-value overtime. According to the Department of Energy, up to 30% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts.

Damage: Animals like cats, birds, and rodents may seek refuge in your nice, cozy ductwork. Lucky for them but not so much for you. Ducts can also become crushed or torn due to humans. Storage boxes are sometimes placed on ducts in the attic (NEVER DO THIS) or duct may be stepped on while work is being performed in the attic or crawlspace.
