Hi, I’m Andrew Coronado, owner of Al Coronado Plumbing and founder of Coronado Home Service Institute. I know firsthand what it takes to build a profitable, customer-focused home service business-because I’ve done it.
My journey started with a Psychology degree from ASU and a career in Social Services, where I learned the power of communication and human behavior. But when the state slashed our budget and my paycheck overnight, I knew I needed a career with more stability and opportunity. Growing up in the trade made plumbing a natural choice.
I worked my way up from technician to field trainer at a nationwide plumbing franchise before joining my family’s business in Tucson. Over time, I transformed Al Coronado Plumbing—growing it from $2 million to over $6.5 million in revenue and boosting our Google rating from 4.0 to 4.9. How? By focusing on process-driven service, not high-pressure sales.
Now, I’m bringing that same proven approach to home service companies through Coronado Home Service Institute. My training program is built for technicians and CSRs who hate pushy sales tactics but still want to drive higher revenue. It’s a research-backed, battle-tested system that makes it easy to educate customers, provide real value, and naturally increase ticket averages—without losing trust.
If you want a team that delivers exceptional service, earns more, and leaves customers saying, “WOW!”, this program is for you. Let’s change the way home service businesses train—and win.
