HVAC ducts are used in all construction. It is important to have proper air circulation in buildings.
The Center for Disease Control does not give any input on how often HVAC ducts should be cleaned. This means they do not pose as a threat if they aren't cleaned. While all HVAC are of various sizes, use your best judgement.
To effectively connect air ducts in your HVAC system, you should first ensure that the ducts are the correct size and type for your system. Use metal screws or duct tape to securely fasten the ducts together, making sure there are no gaps or leaks. Additionally, seal the connections with mastic or foil tape to prevent air leakage. Regularly inspect and maintain the ductwork to ensure optimal performance.
Normaly that is not needed.

Cleaning the AC vent ducts can improve the efficiency of your HVAC system by allowing air to flow more freely, reducing strain on the system. This can help lower energy costs and improve air quality in your home.
Cleaning air ducts can have several potential benefits, such as improving indoor air quality and enhancing the efficiency of your HVAC (heating, ventilation, and air conditioning) system. However, the actual amount of energy you can save by cleaning air ducts will vary depending on various factors. Here are some considerations: Accumulated Dust and Debris: Over time, dust, dirt, and other debris can accumulate in air ducts, potentially obstructing the airflow. If there is a significant buildup, cleaning the air ducts can help restore proper airflow and improve the overall efficiency of your HVAC system. Efficiency of HVAC System: If your HVAC system is already operating efficiently and the air ducts are relatively clean, the energy savings from cleaning may be minimal. On the other hand, if your HVAC system is older, poorly maintained, or the air ducts are heavily contaminated, you might experience more significant energy savings. Air Leakage: Air ducts can develop leaks or gaps, which allow conditioned air to escape into unconditioned spaces like attics, basements, or crawl spaces. These leaks can result in energy wastage as the HVAC system works harder to compensate for the lost air. Cleaning the air ducts alone won't fix air leakage issues, but during the cleaning process, you may identify leaks that can be sealed, thereby reducing energy consumption. Overall Maintenance: Cleaning air ducts is just one aspect of HVAC system maintenance. Regularly changing air filters, ensuring proper insulation, and maintaining other components of the system (such as coils and fans) are also important for energy efficiency. A comprehensive approach to maintenance can lead to greater energy savings. It's challenging to provide an exact figure for energy savings as it depends on the specific circumstances of your HVAC system. If you suspect that your air ducts are dirty or your HVAC system is not performing optimally, it's a good idea to consult with a professional HVAC technician. They can assess your system, identify any issues, and provide recommendations on cleaning or maintenance to help improve energy efficiency.
To improve the energy efficiency of your home by properly insulating air ducts, you can use insulation material specifically designed for ducts to prevent heat loss or gain. This helps maintain the desired temperature in your home, reducing the workload on your HVAC system and lowering energy costs. Insulating air ducts can also improve indoor air quality by preventing dust and debris from entering the ducts and circulating throughout your home.
Perhaps a stuck door in the HVAC system or a blockage in the ducts.
There are many online HVAC part suppliers that carry duct work. http://www.americanhvacparts.com/ has a huge selection, great prices, and reasonable shipping charges.
To effectively repair HVAC ductwork for optimal performance and efficiency in your home, you can start by identifying any leaks or damage in the ducts. Seal these leaks using duct tape or mastic sealant. Insulate the ducts to prevent heat loss or gain. Ensure proper sizing and layout of the ductwork to improve airflow. Regularly clean and maintain the ducts to prevent blockages and improve air quality. Consider hiring a professional HVAC technician for complex repairs or maintenance.
