How to Add a Return Air Duct?

Add a Return Air Duct

Do you know what a return air duct is? It is one of the significant components of your air furnace that travels back to the heater after it is distributed throughout the building via the supply duct. So, if your heater does not have return ductwork, it won’t correctly circulate air, leading to high energy costs. So, you must know how to add a return air duct?

Typically, the return ductwork uses the ceiling joist spaces as the actual “duct” that moves back towards the heater. Hence, these joint spaces empty into the actual ductwork that moves perpendicular to the way the joist runs into the furnace side. So, you must have the right tools to install the ductwork the right way.

What are the Ways to Resolve Return Duct Problems?

If your ductwork is installed in the basement, here is how you can resolve return duct issues:

Expand the Return Drop

The ideal upgrade is to enhance the return drop size. The majority of the return drops are usually undersized, so enlarging them allows turning vanes to the elbows to enable smooth airflow.

Enhance the Return Trunk Duct Size

The second commonest return upgrade is to enhance the size of the return trunk to the equipment. So, a right-sized return drop is useless if air cannot travel back from the return grills to the equipment.

Improve Return Ductwork Size

Sometimes, there is less chance for the air to travel back to the equipment. So, the ideal solution is to redo the return trunk to manage the apt airflow amount. As per the style of the building, you might not require a complete return trunk rebuild. Only a few sections need Air Duct Repair and Replacement Smyrna, GA

How to Add Return Ducts?

A few times, even a right-sized return drop and the trunk does not deliver the required amount of air. Hence, you must look for alternative ways to acquire extra returns to the system in such scenarios. Some house layouts are favorable for installing a floor return in an open region, while others might demand more ingenuity.

If you find tight access in your furnace system, the best way to deal with this issue is to include a return grill to the toe kick of the staircase.

So, when you add a return vessel, always make sure it is not pulled apart from the region with natural draft gas-sourced equipment in it. The reason is that it might create a hazardous situation and probability of CO poisoning.

Things to Remember

While you are focusing on the return side of the furnace, you should not forget the supply side of the heating system. Usually, many supply issues and repairs are necessary for proper air delivery and not the equipment. So, always examine the entire system.

How to Install?

Step 1: Determine The Route of the Ducts

Identify where you want your return canals of the heater. Then, make a hole low in the drywall, where you wish to place your return air grille. And if you are cutting your new return registers into the current dwelling, be careful not to cut any pipes or wires in the wall during the hole-making process.

After this, make a tiny hole with your hand to peep inside the wall before proceeding. Please measure the size of the hole correctly so that it matches a grill size. Then, cut through the floor via the hole. Your hole should be through the basement ceiling beam space. Continue repeating the steps unless you have the desired number of air holes. So, you need to possess at least one per room apart from the toilet.

Step 2: Start Adding Panning

Move into the basement to identify the holes. Begin your work from the furthest hole back, and install the return panning back to the point where your heater is. Pin the panning to the lower extremity of the ceiling joists. So, mark the panning to fit at the furthermost hole, then flex it up and connect it to the floor to shut off the space.

By the heater, halt all the panning in the beams at the same spot. Mark this side also, and move it up to the floor. A perpendicular track to the joists makes holes in the panning. It will be how the air moves from the panning into the return channel to the heater.

Step 3: Hem in New Ductwork

After this, you need to install the square return channel perpendicular to the joist. You want to move it, so it encompasses all the holes you have created in the panning. Then, make holes in the top side of the return pipe to match the panning holes. It enables the air to move into the return ductwork.

You have to fuse the return ducts using s-slips and drive cleats and install them firmly to the bottom side of the ceiling joists so it attaches tightly with the panning. You can consider insulating your ductwork using a foil-faced duct wrap to improve energy efficiency. Using a galvanised peg strap, you can secure the ductwork to the ceiling joist.

Step 4: Add New Air Return Duct to Furnace

Make a hole in the bottom side of the duct, right next to the furnace. It is the point where you will have to connect another duct that will move down to the heater. Make a hole in the furnace that is precisely equal to the hole in the filter rack. Then, connect it from the bottom of the return hole to the filter rack, and connect to the heater. Adjust the duct as required.

Step 5: Installing a New Air Filter

You need to install an HVAC filter in the filter rack, as it will save your money for Air Duct Cleaning Smyrna, GA
