Tape for duct work?
 
I have duct work in basement that I am 99% sure is from my cold air return. There are seems that have little gaps in it that are supposed to be covered with tape. The tape that is currently on it I can not find at a hardware store. Here is a picture of the tape and how it should look if it is doing it's job:

Here is another picture of what it looks like normally:

My question are:

Does it even matter since it is a cold air return?

If it is a problem can I use regular duct tape or should I get the same stuff?

Thanks for your help.

Hi Willie5566

The type of duct work you are seeing is called duct board. The proper tape to use on this is called foil tape. As far as sealing the seams, if the filter is at the furnace this would only cause a problem with the airflow in the house. If the return has leaks in it it will pull the air from the path of least resistance. This can and ususally will effect the overall comfort and operation of the system. My reccomendation is to get a roll of foil tape and seal your seams. Hope this helps.

Good luck
Rusty

Thanks for the help. SHould I be able to buy foil tape at a hardware store? I would have thought it would have been with the duct tape.

Hi Willie5566

Most hardware stores have small roles of foil tape. The tape they generally carry is only about 1 1/2" wide and doesnt stick very well. If you have a HVAC company in your area with a sheetmetal shop, they should have the good stuff. If not if you have a HVAC supply company you should be able to find it there.

Good luck
Rusty

Your other option is to go to www.grainger.com, search for foil tape and they have about fifteen options 2in-4.5in, differant weights, etc. I'd go to the HVAC supply first though as it's going to be about the same price (after shipping ordering will probably be more) and at the HVAC place you can talk to someone who knows what they're doing and get exactly what you need.
