Al Lenz

General Manager

I am an Iowa native who has worked in the Heating and Cooling Industry in the Des Moines metro area for 26 years. I’ve been married to my wife, Jenny, since 2019. I have a daughter and son of my own and two bonus daughters through marriage.

I graduated from Lincoln High School in 1991 and enlisted in the military immediately thereafter. After serving my country in the Marine Corps for four years, I attended DMACC for Plumbing, Electrical, and High and Low Pressure Boilers. I continued my education at Vatterott College where I studied Heating, Cooling, and Refrigeration. I graduated at the top of my class with honors. I then worked my way up through the ranks; Service Technician/Installer, Service Manager, Operations Manager, and finally General Manager. Over the years I’ve acquired a wealth of knowledge in business, HVAC, and my personal favorite, customer service.

In 2009, I embarked on my mission: To own and operate the BEST residential heating and cooling company in the state of Iowa. I carry an Iowa Masters License in HVAC, Heating and Cooling, Refrigeration, and Hydronics. I am Licensed, Bonded and Insured.

I am proud to be the owner of one of the fastest-growing residential heating and cooling companies in the Des Moines area. All I ask for is just one service call or one invitation to your home. I strive to earn your trust before I earn your business. When you choose Lenz, you will soon realize that we focus on building lasting relationships to acquire lifelong clients.
