about us

I am an HVACR Master License Holder and a Licensed Teacher of HVACR, Sheet Metal, and Building Maintenance in the State of New Jersey. I taught HVACR in the Technical High School to adults and High School students. I have over 16 years of experience in the field and also own an HVAC Contracting Business. I created AC Service Tech LLC as a means to provide technicians with in-depth training in a way that is relatable and useful for in the field.


I have seen what it takes for my students to understand and apply the many procedures in our trade and I have used this knowledge to build resources for new and seasoned techs. I want all technicians to have a deep knowledge of our field so that they can grow quickly and have confidence in their skill sets. I will always do my best to present you with the most accurate information available as well as to provide you with up to date processes and procedures. I also make it my goal to explain the relevant information that you are seeking in a manner that is both technical and easy to understand.
