My name is Tim De Stasio. I've been working with HVAC systems for over 25 years. I've worked as a service technician, installer, designer, business owner and instructor. I've learned a lot over this time, and have made a few mistakes too. But what I know, and what I've learned can propel your HVAC career to the next level. Join me as we take the science of HVAC and break it down in to practical knowledge that you'll use every day.
