"I really enjoy following Craig on his AC Service Tech channel. He is an excellent source for demonstrating the proper techniques to follow for servicing and installing HVAC equipment. His teaching is extremely concise and easy to understand."

-Thomas S., Colorado

"Professional A/C work takes time and patience, something Craig amplifies throughout his videos.  His videos are more thorough and exact on the topics discussed.  Another reason you should pay attention to his videos is his number one concern is safety.  How many videos do you watch where a tech who made a "home made" video is NOT wearing gloves. Not with Craig's channel.  When it comes to times when refrigerant could escape and be dangerous, HE'S WEARING GLOVES LIKE A PRO!  Sure it's an inconvenience to do the job without shortcuts, BUT it's the only way to do it  and Craig does it right!" 

-James S.

"I thank you for the time that you have  invested in this channel to help those of us have a better understanding of what we need to look for in order to find a problem quickly and repair it in a short amount of time." 

-Todd P., Illinois

"Craig has taught me a lot about HVAC. I  came across one of his videos when I was going to school. Anyone looking into getting into this trade should start watching his videos and learn as much as you can. As long as you are eager to learn and willing to grow you can excel in this career. Thank You Craig for helping me advance in my career!"

David W.


"These amazing tutorial videos provided by AC Service Tech are PRICELESS"
