Is there a way for a HVAC technician to look inside HVAC trunks with a camera. The trunks were constructed with fiberglass duct board. Everything inside the walls is rigid sheet metal. I’ve heard some bad stories about duct board and mold accumulation.

Many choices for tools, access possible from the equipment end, or from vents.
It also is possible to make a small hole along the way, and seal after.
You also can get a mold test kit.
Never thought of that. Good idea. In any event It would be nice to replace ductboard with sheetmetal. In addition, the HVAC bulkhead takes up lots of headroom. I'm hoping their is a chance to resize the trunks without throwing the system off balance.
A careful analysis of your hvac system would be best if you want to rework the trunks to reduce intrusion into the occupied space.
You may find a local hvac place willing to help (there is work and time required, so expect to pay them), or you can climb the learning curve.
Yes, an HVAC technician can inspect inside the duct trunks using a duct inspection camera or borescope. These cameras are designed to navigate tight spaces and can provide a real-time view of the inside of your ducts. Since fiberglass duct board can accumulate dust, debris, and even mold over time, a thorough inspection can help determine if cleaning or replacement is necessary.
If mold or contamination is found, one effective solution is to replace problematic ductwork with a ductless mini-split system, which eliminates the need for traditional ducts altogether. Mini-split systems provide efficient heating and cooling without the risk of mold buildup inside ducts. You can find high-quality ductless solutions at https://minisplitsforless.com/, where they offer a range of systems to improve indoor air quality and overall HVAC efficiency.
