I own an HVAC company and as stated it is illegal as well as dangerous for you and your family to run any ducts into the garage. You NEED a separate system for your garage, look at a ductless mini split which is what I will use for my garage.
Just read the rest of the posts, all they did was zip tie the vents shut? Wow! You have a bad home inspector, if any of my crew found that we would red tag(shut down the furnace) immediately because it would be a liability for my company since we found a potentially fatal issue and did nothing about it.
Maybe I am just paranoid, but when a competitor was surd for millions over something like his after killing a family and when my fathers friend had a son that had carbon monoxide poisoning due to a faulty HVAC install that my company found you will know why I am so against these ideas that others are saying. You add air to the garage now your garage has a positive pressure and the house a negative, some air from the house will make it back in.
