Did you know that HVAC systems cannot work their magic if installed correctly? Also, good quality ductwork is necessary for proper HVAC functioning. The ends of your house’s ducts link to vents. These vents can be adapted to regulate airflow in every space. So, if the ductwork is loose or completely detached from the vent, then the air can escape, leading to an energy loss. Also, damaged ductwork can significantly hinder the HVAC’s functioning. Hence, this article will focus on how to fix a disconnected air duct by yourself.
What Are the Problems of Ductwork?
You will typically find the ductwork shielded behind walls or within crawlspaces. Regrettably, it implies that damage caused due to home renovation projects and wear and tear can go unobserved. The issue with damaged ducts is that it interferes with your furnace and AC’s capacity to heat and cool your home. Also, fissures and torn seams in ducts allow the dust in and let the conditioned air outflow. Moreover, damaged ductwork surges the strain on your heating and cooling system, which can eventually lead to a severe breakdown.
Duct Seepage and Energy Loss
You must firmly seal the HVAC ductwork to retain conditioned air and the energy it comprises of. So, loose connections, holes, impaired duct sections, and detached duct runs enable conditioned air to exit the ductwork system before it reaches your indoor environment and wastes energy.
Typically, 25% of the air escapes via leakages. In other words, one-fourth of the conditioned air is not delivered to the rooms in your home. Else, an average home loses 20-30% of the energy via duct leakages leading to high utility bills.
How to Test HVAC Ductwork for Leakages?
When you test ducts for leakages, you must use a specialized method for a highly accurate analysis. This procedure uses professional equipment connected to the ductwork system, and then airflow measurements are listed to determine if leaks are present. Apart from specialized testing methods, there are a few ways that homeowners can identify leakages.
Visually examine all the ductwork you can access. You should also peep into your attic, basement, or crawlspace to see if ducts are visible. You should examine everything for apparent gaps, detachments, and tears. Also, know the duct regions that have fixed duct tape. It indicates duct leakages that have been repaired before. You should closely inspect these sections, as duct tape is not ideal for sealing leakages.
You should turn on your HVAC system and access the regions where you can easily access the ductwork. Next, you need to check the connections in every duct section and place your hand on the metal. So, if you feel the air against your palm, it means the duct connection is loose, and there is air leakage. The commonest place for leakage is the duct joint.
While your HVAC system is turned on, you can steadily carry out an incense stick or smoke pencil along with the ductwork and observe the duct for movement. It indicates air escaping from the duct system.
And if you identify any region with an evident or assumed duct leakage, mark them by making an arrow on the duct using a grease pencil to know where the leakage is. After testing the leakages, you can return to these problematic areas and seal the leakage.
Signs of Ductwork Problems
Though your ductwork is not visible, it can be problematic to identify damage. So, you must be aware of some of the signs that hint at the problem:
- Unusual Noises
If you hear an intake of roar to life, it is not something normal. It indicates a problem, and you must contact for air duct cleaning Duluth GA.
- Unbalanced Air Temperature
It is not a good sign if cool and warm air emerges from the vents and hints at a ductwork problem.
- Decreased Airflow
If you notice decreased airflow coming out of the vents, it indicates damage to one section of the ductwork.
- Cold or Warm Spots
If you notice cold and warm spots forming on your home floor and walls, it indicates an air seepage from the impaired ducts.
So, once your HVAC system conditions the air, it needs to move through the ductwork before it cools or warms your region. So, damaged ductwork steals the indoor comfort and makes the HVAC system spend more energy to maintain an ideal indoor environment. In this case, you must contact air duct sanitizing in Duluth.
How to Connect Ducts?
Step 1: Tuck One End
Choose standard duct pieces for the connection that have curly or straight ends but beware of the rigid dryer ducts. If one end is not curled, you must curl it using a tool. Keep the sheet metal within two blades of the device. Crush, release and eliminate the tool. Then, move the tool along with the ductwork opening, and replicate the procedure.
Step 2: Insert Ductwork into Next Part
Insert the curled end of the round duct into the straight end of the following round duct.
Step 3: Seal the Seams
Seal the seams using tape.
Step 4: Fasten the Pieces Together
Insert a half-inch-long tape sheet metal screw at the position where the two ducts overlay to make a solid connection. Insert two extra screws along the seam, keeping equal spaces between the three screws.
Step 1: Connect the S-Cleats
Connect the S-Cleats on two opposing raw metal edges to connect one duct. Ensure that the S-cleats are smaller than the side length that is connected.
Step 2: Streamline the Pieces
Streamline the two rectangular ducts of the same size.
Step 3: Attach the Pieces
Move the two raw edges of the next ductwork into the S-cleat inserted on the adjoining duct.
Step 4: Organize the Drives
Move the drives on the two remaining sides of the ductwork. Make sure to move it one at a time.
Step 5: Seal the Seams
Then, you need to seal the seams among the two ductworks using tape. Make sure to make an airtight connection, as it will ensure high HVAC efficiency.
