I have taken the advanced HVAC
I am currently doing RESNET energy training
About to sign up for the Building Science
Still have a thermal course to watch.
I would like to do the log home course. (I lost one inspection a month or so ago because I did not feel comfortable inspecting a newer log home)
Nachi rocks for education.
Now if I could only get my free manuals.
