Meet Michael Heppler

Owner, Step Up Plumbing | Certified Tankless Specialist | 30+ Years of Plumbing Experience

Plumbing has always been a part of my life. I was born into it—my father was a Master Plumber, and our family ran a retail shop in Mountain View, CA, called Home Plumbing Supplies. Long before big-box stores existed, we were helping homeowners choose fixtures, lay out remodels, and learn how to fix their own plumbing—30 years before Home Depot. While studying at Chico State, I even wrote a paper about turning our shop into a franchise.

Over the last 30+ years, I’ve worked as a Licensed Journeyman Plumber in California, Washington, Texas, and Arizona. From new construction and remodels to service plumbing and running my own businesses, I’ve seen nearly every aspect of the trade. I even spent time working at Rice University in Texas.

But a few years ago, I decided to focus my expertise on what I believe is the future of plumbing: tankless water heaters and water treatment systems. I made this shift for a few important reasons. First, I wanted to get out of attics and crawl spaces and focus on smarter, more sustainable technology. Second, I recognized how the internet changed the industry—people now replace instead of repair. And third, I saw that tankless water heating had finally evolved into a reliable, space-saving solution perfect for homes in the U.S.

Living in Arizona, I also know firsthand how hard our water is. Calcium buildup can wreak havoc on plumbing systems, so I made it my mission to offer high-quality water softeners and filtration systems that protect homes and improve water quality.

Today, I’m proud to be a Certified Navien Tankless Installer—so much so that Navien themselves send me out to fix systems that other plumbers didn’t install correctly. I also install Green Fusion Water Softeners and Whole House Filters, made right here in Mesa, specifically designed to handle Arizona’s water challenges.

I’m not just a plumber. I’m a specialist with decades of real-world experience and a commitment to doing things right the first time. If you’re ready to upgrade your home’s plumbing or just have questions about what’s possible, I’d love to talk.

 Trustindex verifies that the original source of the review is Google. Michael at Step Up Plumbing was the third plumber I called to fix my Navien tankless water heater.  His expertise in both plumbing and the Navien product was evident from the moment we started to communicate.  Michael was able to identify the issue quickly and contacted the manufacturer.  The entire unit (only 2 years old) was under warranty and the replacement was located at a nearby warehouse for same day pickup.  My home has been without hot water for 7 days due to inept and deceitful plumbers.  Red Eagle plumbing was inept and had no idea the entire unit was under warranty which resulted in a 5 day delay for a part that was not needed to repair the unit since the entire unit needed replaced.  Parker and Sons were called on day 6 to get the unit fixed and they graciously agreed to replace the unit for a mere $9800 and could do so the same day.  This company was deceitful in not mentioning the fact the tankless water heater was under warranty with no out of pocket expense to obtain the unit.  This was blatant deceit on their part and I will not do business with this company again.  They were 'happy' to help me out but wanted to charge for the unit which is still under warranty.  I couldn't be more grateful for Michael and his company.  He has saved me thousands of dollars in unnecessary expense repairs.  Michael is an honest and trustworthy plumber whom I am happy to refer friends and family too.

We didn’t end up having Michael do the work because he was so proficient in determining what the previous plumber had done wrong with our electric water heaters. Not only did he consult with the manufacturer of the heaters, he also told the previous plumber what he had done wrong and without both of those things we wouldn’t be getting our $7k issue resolved at no cost to us. This is what I call honest business. Hard to find honest people in any industry anymore and I can tell you all of our future needs will be brought to him first going forward.

 Trustindex verifies that the original source of the review is Google. After our old water heater rusted out and started leaking, we decided to make the jump to a tankless. After speaking with Mike, he had us scheduled for an appointment right away. We got lucky, as he had the unit we needed on hand, and installed it in a single day. We are very pleased with our new unit, as hot water hits the bathroom on the far side of the house very quickly, and we don't have to worry about running out! The tankless unit takes up so much less space in the garage, and is much more efficient than our old one. He even took away the old water heater so we didn't have to deal with getting rid of it. A great experience overall, and would highly recommend giving Step Up Plumbing your business!

 Trustindex verifies that the original source of the review is Google. Our old water heater was close to rusting out. We decided to drop the hammer and go tankless, and all I can say is wow! It has been almost a year now. It is nice having hot water whenever and however long we need it. About a week after it was installed, we ran all three showers at the same time and nobody got cold water. My kids sometimes take very long showers; that is no longer a problem, as we will never run out of hot water. It has run flawlessly. Mike was fantastic. He was on time and very communicative about the whole process. Thanks again Mike!
