7 Hazards Air Duct Sealing Can Protect You From

Like many people, you probably don’t think of air duct sealing and the hazards it can avoid when scheduling HVAC maintenance. Properly sealed ducts ensure your heating and cooling system works properly and increases efficiency. Duct sealing also has safety implications. Several hazards can be encountered if you have leaky ducts. As The Greater San Francisco Bay Area’s leading air sealing specialists, we’ll explain the top safety concerns of poorly sealed ducts.

1. Backdrafts

Furnaces, water heaters, clothes dryers, and other gas-using appliances normally vent noxious gases out of your home. However, gases like carbon monoxide and sulfur dioxide can enter poorly sealed air ducts and “backdraft” into your home. Breathing these in can get you very sick or be deadly. Therefore, air duct sealing can save your life.

2. Poor Air Quality

Aside from toxic and combustible gases, poorly sealed ducts can allow various other pollutants into your home that reduce indoor air quality (IAQ). These include dust, particles from deteriorating insulation, and fumes from cleaning chemicals. You’ll breathe these in all day and while you sleep. A local HVAC contractor should test for them and other indoor air pollutants before and after sealing your air ducts to ensure any underlying issues are resolved.

3. Health Issues

Poor IAQ, which can result from leaky ducts, may impact your health significantly. The symptoms persist as long as your air is contaminated and are most prevalent while you’re at home. You and anyone in your household can get very sick if nothing is done about it. Therefore, consider air duct sealing whenever you experience the following symptoms:

• Eye, nose, and throat irritation
• Coughing and sneezing
• Sinus congestion
• Shortness of breath
• Headache
• Dizziness
• Nausea
• Fatigue

4. Pests

The tiniest air duct leak is enough for roaches, ants, spiders, and other bugs to get into your home. Rodents and other small animals can also get through holes, gaps, and tears in ductwork. Pests aren’t only something you don’t want to see. They can also cause harm to your health and home. Fortunately, well-sealed ducts can prevent them from getting inside.

5. Moisture Damage

Air duct sealing can protect your valuables. If your ductwork leaks, indoor humidity can become out of control, leading to moisture damage to wood furniture, flooring, antiques, and everything from books to appliances.  Drywall and other building materials can also be damaged. Moisture issues combined with other problems related to poorly sealed ducts can impact your home’s infrastructure and reduce its long-term value.

6. Mold

The presence of moisture increases the risk of mold growth. Mold can grow in the dark confines of air ducts and spread uncontrolled while releasing spores into the air. Since many types of mold are toxic, it’s important to address the issue quickly. 

To make matters worse, the moisture entering air ducts will reach conditioned spaces. This provides mold with the right environment to continue growing and spreading. It can grow on walls, ceilings, furniture, carpets, and just about any surface if there’s enough moisture.

7. Discomfort

Significant air duct leaks can allow outside air in or let conditioned air escape. When either of these issues happens, your HVAC system must work harder. But no matter how overworked it becomes, heating or cooling your home is more difficult. 

Poorly sealed ducts can leave your family too warm or too cool. Setting and resetting the thermostat does not help, and you end up being uncomfortable all the time. This makes it hard to be productive, enjoy your home, or even sleep.

Can Air Duct Sealing Present Hazards?

Sealing air ducts is safe when done by a professional. Consider hiring a contractor when your HVAC system is installed, you move into a new house with an older HVAC system, or when maintenance is scheduled. They have the knowledge and tools to work safely and seal your air ducts properly.

The risks mostly pertain to DIY air duct sealing. Trying to save on the costs of hiring a professional can do more harm than good and lead to more expenses. If your ducts are insufficiently sealed, air leaks can still occur. Improper sealing can also cause harmful chemicals to be released into your home, especially if you have little knowledge of sealant materials.

You also risk causing damage to ductwork, creating air pressure imbalances, and triggering issues with home heating and cooling.
