DIY Vent Extender For Furniture

I will show you how to make an Inexpensive DIY Vent Extender For Furniture for only $2.00 using Dollar Tree Supplies. It’s a safe and practical alternative to spending $20.00 for one like this.

Why are all the Heat and Air vents in the exact place you want to arrange your furniture? There are Vent Extenders available for purchase, but we needed two, and $40.00 seemed like a lot for something hidden beneath the furniture. So here’s what we did.

What Is The Purpose of A Vent Extender?

The purpose of a vent extender is to redirect the airflow from a heating and air conditioning vent that may be impeded due to furniture placement. If the vent is under a sofa, dresser, or bed, the vent extender will direct the airflow from underneath the furniture blocking proper airflow.

Is It OK to Put Furniture Over The Floor Vents?

This is the question I asked my husband, and here is the result of his research. The second sentence in this article convinced us that YES, we needed a vent extender.

“The short answer to this question is, “No, it’s not ok to block the airflow.”

Vents are there to provide for a necessary free flow of air. Block that flow, and your home will run sub-optimally, and you may also cause damage to your HVAC system.” You can see more reasons to use an extender in this article from Hunker.


How To Make a DIY Vent Extender For Furniture

First, you will need to make a trip to The Dollar Tree, but measure the size of your floor vent before you go. Also, measure the distance from the vent to the edge of your furniture covering it.

Once you are at Dollar Tree, you will notice that they have multiple sizes of Aluminum Baking Pans for $1.00. In addition, they have Silver Duct Tape for $1.00. That’s all you need.

Just be sure the pan you purchase is long enough to extend to the edge of your furniture and wide enough to fit over the floor vent.

If you are working under a sofa or bed, you may need more than one pan to extend to the edge of your furniture.


How To Measure and Cut for DIY Vent Extender?

First, using the measurement from the back of the vent to the edge of the furniture, mark the baking pan at that distance.

You should be able to cut the pan with simple scissors.


How To Attach The Extender For The Vent?

Next, using duct tape, attach the pan to the vent securing three sides, as shown in the photos.

The rim of the pan fits almost perfectly along the edge of the vent.

Insert the Vent Cover with Extender Attached Over Vent Opening

Finally, making sure the vent is open, place the cover back into the opening.

Then, place your furniture back over the vent extender and make sure everything is aligned correctly. If you fail to cut enough off the aluminum pan, it’s easy to trim any excess.

You want the extender to be as close as possible to the edge of the furniture.

Here you can see how closely the extender fits against the furniture.

Thanks for stopping by. I hope you found this helpful. I look forward to sharing my next adventure with you.

Brilliant! I used your idea, except I swapped the silver duct tape for silver HVAC tape. That might provide a slightly better seal. Works perfectly!

Well done! I bought two $1 packs of two of cake pans at the Dollar Tree. I used all four and duct tape to extend 33" from my wall under my couch. It worked great and the heat is making it to the center of the room too. Cake pans were 2" so the support lips just spread to accommodate the 1.5" clearance. I prefer the aluminium over cheap meltable plastic sold for $10-20.
