I'm afraid I don't understand all of what you are trying to say. What is the context?
- and take a chance on: ??
- and need your help: why do you need help, and what kind of help?

You could say this:
Our company is to perform maintenance on a compressor between November 12th and November 17th (or from ... to ...?). We will be cleaning the cooler, but we need your help to inspect it with a borescope in order to find potential obstructions or other problems.
