I am really up in the air about this and about 2 weeks away from completion.  

The house has central air and we just replaced the A/C unit last summer.

This coverage will offer defense and claims settlement for alleged or actual injury caused by CO2 emissions from a heating or air conditioning source.You can add a "personal umbrella" to cover your personal liability exposures of your home and auto, if your net worth justifies it, but you should keep any income producing assets separate from your personal liabilities.There are very few companies who understand this and do it right but once you get set up right and realize how much easier it is to manage and scale your business up, you'll be glad you did.Ivan
