Our garage had two vents hooked up to our AC/Heater. We did not want to pay to heat and cool our garage, and even with those two vents closed we were still wasting air.
So I ventured into our cramped attic and found the spot where the duct branches off to the garage. It takes about 15 minutes of army crawling across 2X4s and dodging air ducts and insulation to get there. I had planned everything out ahead of time, but of course nothing went like I expected. I ended up having to crawl over there twice, and the second time I spent about an hour and a half removing the duct and sealing it off. The duct on the right splits into two and goes to the two garage vents.
