This is the first day of fall, and that means it may be time to pay attention to your HVAC system as the season changes. So let's talk air conditioning, not about using it, but rather about not using it and prepping it for the winter.

Jason started the conversation by asking dean what if we did nothing more than turn the air conditioner off... is that still okay?
