Inspection Period - HVAC and Other?

[Chris V.]

We have our first two duplexes under contract and are completing inspections. After the general home inspections, a few minor issues were found like a couple of plumbing leaks, a roof leak, couple of venting issues, a split beam in the attic. One of the HVAC units didn't come on when tested, so that's a possible issue. Also one of the ducts has a tear, doesn't seem difficult to fix. The other three HVAC units didn't seem to have any issues, but the inspection company recommended we might want to have those inspected by an HVAC specialist. What do you guys recommend here? Should I pay to have all the HVAC units inspected? Other inspection we plan to have is for termites (in South Carolina). Any other suggestions or thoughts?
