Reply to comment by usedTP in Gable Vent in Unfinished Garage? by AggravatingTart7167

Thank you both. Going to drill out some soffit vents (wood trim) and put in the gable vent. Probably looking at a new roof in the next two years anyway, so just trying to get things going in the right direction. No pun intended.

Put two in the attic in my old house for HVAC, it set the one at 120ish and seemed to run nonstop from June-October.

But do you have a flat soffit or a sloped soffit?? Sloped makes venting more complex and it’s completely untrue that you need soffit and roof vents for venting to work well.

Also it’s way way more complex to size all of this. Look in the IRC there is an entire code section on how to calc and what’s required Chapter 8
