ONE TEAM. FOCUSED ON YOU.

At Hartwig Mechanical, our One Team goal starts with what matters most—our customers.

Across Harvard, Rockford, and Mokena, we bring together Plumbing, Mechanical, HVAC Service, Special Projects, and Building Controls to support your facility. Behind every project and service call are field professionals, warehouse teams, and office staff working toward the same goal: delivering quality work and an experience you can count on.

For our customers, that means shared expertise, clear communication, and coordinated support—from routine maintenance and unexpected repairs to system upgrades and new installations.

We’re investing in our people, strengthening collaboration, and building lasting partnerships to keep your facility running and your business moving forward.

Three locations. One team. Focused on you.

Let’s talk about how Hartwig can support your fac

Dear Justin,

Thank you so much for joining us for Sporting Clays for Scouting at Camp Lowden. We appreciate the Hartwig team joining us for some fun and friendly competition on the course!

Sporting Clays for Scouting makes a tremendous difference in the lives of our Scouts and families by helping Blackhawk Area Council keep the Scouting program available in northern Illinois and southwestern Wisconsin. Your time on the sporting clays course helps us deliver out-of-school learning opportunities, career education, leadership skills instruction, ethical decision making, and so much more to young people.

We hope you and your team enjoyed Sporting Clays. I have attached a team photo as a small memento of the day.

Please save the date for next year’s Sporting Clays for Scouting at Camp Lowden, September 10-11, 2027. We will also hold a Sporting Clays for Scouting Shoot at Northbrook Sports Club in Hainesville, Illinois in June of 2027.

Thank you again for your support!

Respectfully,

Alice M. Roby
Development Director

Today, Hartwig Mechanical pauses to remember the lives lost on September 11, 2001, and those who have passed in the years since from illnesses related to that day.

We honor the courage of the first responders, the selflessness of ordinary people who stepped forward to help, and the strength of survivors and families who continue to carry the loss.

Behind every name is a person, a family, and a story that deserves to be remembered.

We will never forget. 🇺🇸
