Seems like he was having some remorse and when confronted with a viable solution came up with an excuse.

I would love to confront the issue head on but want to do so in a way that does not cause them to retaliate by smoking more or cause further damage to the unit.Thank you in advance for your suggestions!

I know, most people are scared when confronted by a little math.

Confront him directly.
