Hearing loud Popping and Banging noises coming from your home’s heating and cooling system could mean an issue with the air ducts. Noises like popping, banging, and knocking indicate that something is wrong and should be addressed. To reduce or eliminate the noise, you can check the ducts for any signs of damage and make sure that they are properly connected and sealed.
Nobody can completely eliminate all of the popping and banging your HVAC system makes, but there are some steps you can take to make it quieter. These could include inspecting the system for loose parts, sealing ducts and insulation, and improving the airflow.
1. Seal and Insulate Ductwork
To address the issue of pressure differences in your duct system, it is recommended to hire a professional HVAC company to clean, seal, and insulate your ducts. This will help to reduce the expansion and contraction of the metal ducts and make them more effective. A good HVAC company can provide solutions such as acoustic duct liners, duct sealing, and fiberglass insulation to help with this. While it may be costly, this is the best option, short of replacing your entire duct system.
2. Change Air Filters
Replacing your air filter regularly is an important part of keeping your HVAC system working efficiently and improving the air quality you breathe. When you don’t change the filter, airflow becomes restricted, impairing the system’s performance. To ensure the best operation, it’s advisable to swap out your air filter every one to two months.
3. Get HVAC Maintenance
Having a well-maintained heating and cooling system is important to ensure your home is comfortable and quiet. Ensure your furnace and air conditioning are checked and serviced every season. Consider signing up for a home maintenance plan to make sure you remember to do this task and that your HVAC system is running efficiently. This will help reduce any unnecessary noise coming from your HVAC system.
4. Check Dampers and Actuator
A damper is a device inside a ductwork system that can be adjusted to control airflow. The damper can either be opened or closed. To reduce loud noises from the ductwork, you can check the dampers on the supply side and try opening them one at a time to see if it helps. You can also adjust the actuator inside the duct dampers to reduce the noise.
5. Choose Circular Vents
Circular vents generally produce less sound than their rectangular counterparts since the walls of rectangular vents are more flexible, allowing them to vibrate more easily. On the other hand, round vents have more structural support, so they tend to stay still, resulting in less noise.
Conclusion of Popping And Banging
The popping and banging of air ducts can be a nuisance for any homeowner. You can eliminate this problem by cleaning the duct, adding a vent, properly insulating the duct, or totally replacing the duct. Homeowners can also hire a professional to fix the issue if they cannot do it themselves. All these steps can help homeowners stop their air ducts from popping and banging.
