I would - and add broken, cracked, and/or rusted out (or deteriorated if cardboard - yes I did say cardboard ducts similar to Sonotubing, useda lot in the 60's-80's especially. I would pay the $100-150 typically cost of having a Duct Cleaning company or Heating and AC contractor (your two Search the List categories) run a duct camera through them to see what the materials and condition are.

If not rigid pipe (Schedule 40) plastic or fiberglass commonly are pretty shot within 5-10 years. If unable to find a local vendor with duct camera, a sewer cleaning company with sewer camera (really same camera, sewer ones just usually have 100' cable on them instead of 25 or so and are waterproof) - be sure he disinfects cable before running it so owner can't say you contaminated his ducting. So obviously better to use a duct cleaning/HVAC company if you can find a local one with camera.

In some cases, if you are lucky, you can just remove grating over the duct and use a mirror to look through the ducts, if straight or maybe only one bend (looking from both ends).
