"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!"
