Meet Mike Lorenz Polino

Mike Lorenz Polino, owner of Lorenz Plumbing, Heating & Air Conditioning grew up in northwest Springfield and graduated from Hillcrest High School. He began working part time in the plumbing industry when he was 15-years old. While in high school he also attended the Graff Vo-tech plumbing program which led to his first full time job after graduation with a local plumbing contractor. A few years later, he was fortunate to start working alongside his family at Lorenz Plumbing, Heating & Air Conditioning which led him to where he is today. Mike is happily married with four grown children, one of whom has worked in the HVAC division since high school. The entrepreneurial spirit and commitment to customers that started Lorenz over 40 years ago still lives strong today.

As Springfield grew, Lorenz benefitted from that growth in new construction. Over the many years, Lorenz has done plumbing and HVAC work on custom homes, apartments, retail centers and warehouses. Their success was because of the exceptional network of friendships with local contractors that still run deep.

Now, Lorenz is bringing that success and experience back to where it began, direct to customers to focus on plumbing heating & air conditioning needs in their homes and businesses. After all, they know the ins and outs of plumbing, heating and air conditioning after 40-years’ experience. If there’s a problem you have, they’ve probably seen it…. a lot. And that’s why they’re your friends in plumbing, heating and air.

Our client stories

"Prompt, friendly, courteous… Everything you could want from a plumbing company! I will definitely call them next time I need plumbing services!"

"They were able to come out the same day I called to repair my furnace. The repair tech was friendly and finished the job quickly. Price was reasonable. I highly recommend and wouldn’t hesitate to call again."

"I was originally scheduled for the following day, but Lorenz worked me in on the day I called. They installed a garbage disposal and fixed a leak. Ryan was knowledgeable, pleasant and professional. He is an asset to the company – as is Chelsea, who worked me in."
