The photo shows both a larger heating/cooling duct and a disconnected dryer lint duct... Can you spot the concerns?
During the inspection, it was noted that the soil was very moist.. That the large duct is not supported off the ground... And is in contact with the moist ground.
There can be moisture and rodent intrusion, that could lead to health issues.
Flexible clothes dryer lint ducts are not permitted for use in a crawlspace and are prone to lint buildup. The open lint duct discharges warm, moist air into the crawlspace making the wood framing susceptible to fungus growth...Lint accumulation under a house is a potential fire hazard, as line is flammable.
Lint ducts in a crawlspace are to be rigid, smooth-wall ducts without sheetmetal screws penetrating the duct, supported every 10 feet, taped at the duct sections, and terminating at the exterior.
There’s a brown silt mark on the white flexible duct... an indicator that water has accumulated. Standing water and water intrusion into ducts is not a good thing.
Recommendation was for further reviews by a licensed HVAC contractor and a drainage expert.
