Do you know why it is essential to fix draining flexible ductwork? You can save money and not be bothered by extreme temperatures. However, this repairing task is pretty easy if you have a guide on how to repair flexible ductwork. So, here are the steps to teach you how to do it.

 

What are the Steps to Fix Ductwork?

 

Step 1 – Identify the Leakages

The initial thing that you need to do is to identify the point of leakage in the ductwork. It is pretty easy if you have access. You need to switch on the temperature and inspect for air leaking through holes or cracks. Also, you need to see if any ductwork has been completely ripped off. The majority of the time, you may find a fully damaged section that you will have to replace.

 

Step 2 – Repairing Ductwork

If you want to repair flexible ductwork, there are several ways to do it. However, the method you choose depends on what needs to be fixed. Suppose, if there is an unfastened connection, you can use a Panduit strip to repair it. You will have to tug back the external layer and fasten the strap to it. For this, you may want help from someone to keep it firm. After this, you may have to use sealant and a paintbrush to ensure that it is secure.

 

Another method to fix the ductwork is to use mastic tape. If you identify a small tear, you can use duct tape to join the tear together. After this, you can use a paintbrush to apply a small mastic sealant and press the sides together. After everything is dried, you can apply the mastic tape to secure it.

 

And if you find that there is a hole that you cannot repair, you can use a caulking gun and mastic caulk to fix it. Let it dry for some days before you use the ductwork again so that dust and debris don’t get stuck.

 

Step 3 – Inspect

After you are done with repairing, you may have to inspect the ductwork to ensure everything is functioning perfectly. Allow the duct to be set for at least a day, and then you can test it. You can vary the temperature up and down so that air can run through. After this, ensure that there are no leakages.

 

If you have shredded and damaged flex ducts, it will majorly compromise your HVAC unit’s efficiency. And you will have to pay high energy bills. Also, hiring an Air Duct Repair and Replacement in Atlanta is quite expensive.

 

You might be amazed to learn that you can quickly fix your ducts and save money even in the worst scenarios. For repairing, you may require an HVAC duct tape, mastic tape, paintbrush, mesh, cutter, wire, Panduit straps, and metal collar.

What are the Tips to Repair Any Holes or Fissures in the HVAC Ductwork?

 

You should know that the efficiency of your heating and cooling unit depends on the quality of your ductwork. And if there are any holes or fissures, it can allow conditioned air to escape, thus reducing the entire system’s efficiency.

 

Even more, the holes and fissures allow germs, contaminants, dust, dirt, mold spores, chemical fumes, insulation fibers, and filth to enter the system. Hence, it will pollute your indoor air quality and increase your risk of health problems. Also, it will overburden you with high energy bills. While repairing the damage is a simple task. You may not even have to invest in hiring an Air duct cleaning expert in Atlanta. So, why not save big and protect your health by following these tips:

 

Seal the Minute Holes

For this, you need to thoroughly wash the entire ductwork with soapy water, rinse with fresh water and allow it to completely dry. After this, you need to seal the duct hole using the underwriter’s laboratory 181 foil-backed tape.

 

It is a safe tape and is entirely safe to withstand high-heat conditions. However, if you use any tape that is not safe to use, there might be a risk of smoke and fire hazard. Take a 6 inches long tape strip, stick the edge right above the side of the hole and cover the tape over the duct. And when you come to the initial point, slightly overlay the tape and make another spread the duct. Keep doing it until the entire gap is sealed.

 

Cover the Bigger Holes

After you clean the ducts:

  1. Take the hole’s measurements (height and weight).
  2. Add one inch extra to each measurement.
  3. Using a marker, measure off these measurements on an area of 26-gauge sheet metal and remove the section with sheet metal clippers.

 

Spread the metal patch sheet on the gap. If you are repairing the sheet metal duct, you can use a power screwdriver to drive a self-tapping piece of the metal screw into every corner of the area. For a fiberboard duct, protect the area with a foil tape strip on each side. Eventually, run a blob of silicone caulk around the corners of the patch to prevent any air seepages.

And if you want to enhance the HVAC ductwork efficiency further, make sure that the joints are secure and covered with mastic or foil-backed adhesive tape, and the duct is insulated on the unconditioned areas.

 

Conclusion

Ductwork passes through areas of your home like open-ended air spaces in the attic, basement, crawlspaces, or even the outer side of the home. Hence, any damaged or ripped insulation can cause heat gain or loss (depending on the time of year). If there is a heat loss, it will place pressure on your heating system, and if there is an increase, then your air conditioner functioning will be compromised. Besides, during summers, the temperature differential can cause condensation in the pipe, which can cause water damage to the adjacent material. And when you fix the damaged insulation by following the simple steps and tips mentioned above, you can enjoy great benefits and a comfortable environment.
