Ductwork inspection

I am having a big problem with air circulation from my HVAC system. In trying to troubleshoot this problem I purchased an inexpensive inspection camera to see if I could check out the inside of the ductwork to see if there is some kind of restriction in the ducts. The camera works fine, but the 16 foot cable is too flexible and gets hung up when I try to push it into the ducts. When I push it very far into the ducts, it starts to double up on itself and won't go far enough to get a good look. Any ideas how I could maybe attach this cable to something else that is more rigid, like an old piece of garden hose or something else. At my age and large body, crawling under the house to inspect the ductwork is not an option. Any ideas or suggestions would be appreciated.

You could try attaching it to fish sticks.

What type duct do you have? Is it a metal box or round metallic pipe or is it flexible plastic?

Where is your air filter located? 've seen duct problems caused by a dirty filter getting sucked into the ductwork. I have also seen flexible ducting collapse or pinch shut. And, occasionally someone hiding things (drugs, porn, alcohol...) inside the duct.

Use anything you have on hand to make it work. Get creative with duct tape. You can tape long straight things together with the camera taped to the end. Just make sure you tape it together well enough that it doesn't come apart in the duct. I've used paint roller extension handles, broom handles, flexible duct cleaning rods. Just look around your house and think of what might be useful. Unfortunately, bends will limit how far you can view. Sometimes it's just easier to take the duct down and look.

Ductwork inspection

Thanks for both of the responses. I had not heard of fish sticks. Looks like that may be a good idea if I can't find something else. Whatever I use needs to be flexible due to bends, curves and joints in the ductwork. I have plenty of duct tape as suggested so its just a matter of finding something flexible to attach the camera to.
