Redundant chimney problems.

I'm having problems with a potential leak or condensation problem in an external chimney chase that no longer has hot air running through the exhaust venting. I've not had any luck with the contractor that made the chimney redundant and need some advice.
So two years ago we had our furnace and water heater replace with newer efficient models. The new units had venting installed directly outside rather than using the old chimney. The contractors capped the old exhaust vents, which run through an external chimney along the outside of our two-story house.
In the fall we had the old gas fireplace on the ground floor replaced, with a newer more efficient model that vented directly to the outdoors. Again, the contractors capped the old exhaust, which used the same chimney system as the old heater and water heater.
Now that the weather is finally starting to warm up, we’re starting to hear an infrequent dripping noise in the second story section of the now unused chimney system.
We’ve checked with both of the companies that installed our new equipment and they are assuring us that the capping process was for both the top and bottom of the disconnected vents and that the dripping wouldn’t be from the old vent lines. We’ve also checked with a couple of roofing companies and they say they don’t handle anything related to chimneys and that the infrequent dripping doesn’t sound like a problem with the flashing.
My questions are:
Other than ripping open the wall to look into the old chase way, is there anyway for me to track the source of the leak?
What type of contractor should I be contacting to track down and solve this leak, if it is something I can’t handle myself?
