When it comes to the maintenance of ductwork, many people think they are beyond their capabilities. This article will provide some basic tips on repairs and installations. You’ll also learn how to clean the duct board and fix torn flexes. You’ll also learn about how to repair and install a splice connector. Fortunately, you can do a lot of this work yourself if you have the right tools and the right skills.
Repairing a splice connector
The CoolSplice connector is a wire-to-wire splice that combines ease of termination with reliability. Its unique insulation displacement crimp technology eliminates the need for specialty tools or professionals.
The clear sidewall confirms the connection, while the cool, durable insulating body of the connector prevents moisture from seeping into the connector. The CoolSplice connector, otherwise known as the twist-on wire connector, has a portfolio that now includes connectors suitable for 22 to 12-AWG wire, with blue, yellow, and red color-coded termination buttons to identify the wire.
To repair a splice connector, first, clean the hole. Then insert the new splice collar. Then, use duct tape to secure the new part. After the duct liner is properly secured, you may apply mastic using a caulking gun, putty knife, or squeegee. Lastly, tighten the new splice collar with a self-tape sheet metal screw.
Repairing a torn flex
The outer covering of the flex duct can tear, causing energy loss and moisture accumulation. The problem is worsened when the damaged section is exposed to rain or snow. In extreme cases, a section of the ductwork needs to be replaced. However, minor flex tears can be repaired by sealing the torn section with 15-mil butyl tape and mastic.
It is important to ensure that the discharge grille facing does not touch ceiling joists or wall studs. To repair a torn flex on air-duct and cooling units, start by locating the affected area. To do this, use a probe to locate the affected area.
In most cases, it will be a metal or plastic flex pipe. To repair the interior of a duct, use a non-serrated knife blade to slice the wet section. The serrated blades will grab the reinforcement threads on the foil backing. These triangle-shaped lines can be seen on the outside of the duct.
You should check the flex duct annually for cracks or tears. If there is any asbestos on the ducts, you should replace them immediately. Asbestos is hazardous to health, so it should only be removed by certified companies. New flex ducts can be installed by any duct repair company.
Cleaning a clogged duct board
If you’re heating or air-conditioning system is not working properly, it may be due to clogged ducts. Check the airflow in each vent to determine the problem. If there is weak airflow in one area, the problem is likely a clogged duct. If it is, it may be time to replace the ductwork.
While cleaning the ducts may improve the air quality, it is important to address the problems that led to the clog in the first place. Cleaning the ducts yourself will not fix the problem, so hiring a professional like Redwood Heating and Air LLC can help you do it safely and effectively. For example, if rodents or mold are the culprits, it is necessary to address the issue that allowed them to grow in the first place.
By cleaning the ducts alone, you may only make the problem worse and will have to pay more money for the same service in the future. There are many reasons why ducts are clogged, including the accumulation of dirt and debris. Dirty ducts can reduce the efficiency of HVAC system components, reduce airflow and create a breeding ground for microbial growth.
These contaminants can affect the quality of indoor air for all occupants, but they are especially harmful to people who have respiratory or cardiovascular problems. When hiring a duct cleaning service, make sure the company is registered with NAIMA and has experience in dealing with your specific system.
Ask to see a microbial count on your duct board and have a lab test to confirm the problem. Once the cleaning is completed, call your EPA-certified service provider for a quote and schedule. Make sure the company has a good reputation, has the experience, and is licensed in your state.
Repairing a leaky duct board
If you have a leaky duct board in your ducted and cooling unit, you can do so yourself in a few ways. First, you need to expose the leaking seam. To do this, you can remove the panel from the wall and loosen the hanging straps and brackets on either side of the leaky area.
Then, you can inspect the duct board for large gaps. If the duct board has large gaps, this could be due to improperly installed S-locks. Moreover, a damaged / leaking duct board can increase your utility bills. Hot air and cold air from a leaky duct can result in a higher utility bill.
Getting a professional to repair the duct board might be expensive, especially if the ducts are located in difficult locations. Nonetheless, with the right tools, guides, and experience, duct cleaning and repair can be done by you. If you can locate the leaking ducted board, you can cut it with a non-serrated knife.
Next, you can apply foil-backed duct tape over the duct board and press it with a squeegee. Alternatively, you can apply a mesh by using 1/8 inch thick duct mastic. This method will prevent air from leaking into the duct. After identifying the leaking duct board, you can proceed with the installation. Ensure that the duct board is connected correctly so that air can pass through.
Once it has been connected properly, you can then apply duct tape to the joints. It is important to be aware of the dangers involved when installing duct boards. If you can avoid such dangers, hiring a professional will help you to avoid any legal issues and safety problems that may arise with no training.
