Hello, I've had luck with these type of forums for cars and motorcycles and when I was looking for info on a Gallo gun I found this place. Seems like it would be a good resource so I thought I would sign up. I've been a HVAC tech for about 5 years now, I started out with new construction installs and replacement installs. Worked my way up, learning everything I could from anyone willing to teach and lately I've been getting the new techs doing they're ridealong training with me, not saying I know it all ha far from it. Looking forward to getting into the pro section.
