In this episode of Building HVAC Science, Eric Kaiser and Bill Spohn welcome Craig Migliaccio, the creator of AC Service Tech, author, educator, and industry influencer. Craig shares his journey from teaching HVAC in high school to becoming a prolific author and content creator, driven by a passion for making practical, hands-on learning accessible to HVAC professionals and students. With over 60,000 copies sold of his first book and a rapidly growing suite of resources, Craig has made an indelible mark on the industry.

Craig discusses the challenges and rewards of writing technical books, the value of bridging the gap between theory and practice, and the immense effort involved in producing educational materials. His team-driven approach and dedication to quality are evident in his books, training tools, and YouTube channel, which boasts over 500,000 subscribers. Craig also emphasizes the importance of work-life balance, family, and faith, encouraging listeners to prioritize their well-being alongside their professional goals.

Craig’s motivation to write came from gaps he observed in existing HVAC textbooks, leading him to create step-by-step, procedure-focused resources.

Building a robust educational platform requires collaboration, persistence, and a willingness to iterate and improve.

Craig’s advice to technicians: prioritize family, invest in knowledge and skills, and focus on meaningful connections in the industry.
