Ductwork is a vital component of your home’s HVAC system, used for distributing conditioned air throughout your rooms. While ductwork usually operates without a problem, issues can occasionally arise that may reduce your HVAC system’s efficiency and could require an unexpected air conditioning repair. Here's a guide to a few of the most common duct problems and how they can be fixed.

What Are Common Ductwork Issues?

1. Leaks

As much as 30% of conditioned indoor air can be lost due to leaks and holes in the ductwork. This can lead to higher utility bills and a less efficient system as your HVAC equipment consumes more energy to cool wasted air.

Leaks have a variety of causes, including deteriorated sealant on connection joints, damage from rodents chewing through duct materials, and added strain if a house's foundation has shifted. An air conditioning repair specialist will pinpoint the location and severity of the leak using specialized diagnostic tools and then repair the puncture to minimize wasted energy.

2. Dirt & Dust Buildup

As air passes through your HVAC system, it carries with it dust particles, dirt, mold and mildew spores, and other contaminants, which can then settle in your air ducts. In fact, research has shown that indoor air is often two to five times more polluted than outdoor air. This is both harmful for your health and can reduce your HVAC system’s efficiency since the system can get clogged with heavy buildup. To eliminate the accumulation and keep your system functional year-round, schedule professional air duct cleaning every three to five years. 

3. Insufficient Airflow

If you notice reduced airflow coming from your vents and registers, it may be due to a broken blower motor or another mechanical component. However, this issue is also commonly caused by kinked, twisted, or crushed ductwork or by an obstruction within your system. Although this problem is more often seen in flexible ducting, solid metal ducts can also become blocked or damaged, leading to inadequate airflow. If your home's airflow has been low, an air conditioning repair technician can inspect your ductwork for signs of blockages or failed mechanical components to restore your system's normal functioning.
