The number of women in the workforce reached a record high in 2023. Yet, the U.S. Bureau of Labor and Statistics reported that only 10% of mechanical engineers and only 2.3% of HVAC mechanics and installers are women.

As the HVAC industry continues to evolve, Johnson Controls believes a diverse workforce that empowers women is crucial for continued growth.

women STEM graduates

"As a woman business pioneer and engineer, it is extremely exciting to see the increasing numbers of women STEM graduates,” said Lei Schlitz, vice president and president of global products, at Johnson Controls.

The industry has made significant advancements in recent years, but as we look to the future, we need to continue to tap into the greater pool of talented women professionals who are our next-generation business and functional domain pioneers.

Women advancement initiatives

Rise Up: Women in Leadership Program, which explores the unique issues women face

To support the advancement of women in HVAC, Johnson Controls has launched several initiatives, including the Women’s Global Network and the Rise Up: Women in Leadership Program, which explores the unique issues women face in the workplace and aims to enhance women’s leadership skills through sessions focused on personal development.

These sessions cover topics including “Rocking Your Confidence,” “Owning Your Career” and “Networking.” 

Women in Engineering and Women in Controls

The company’s Women in Engineering and Women in Controls programs also target opportunities to bring women into the field and provide resources for long-term career growth.

Additionally, Johnson Controls believes peer-to-peer support plays a powerful role in carving a path for women’s success. In honor of International Women’s Day, Johnson Controls is celebrating a few of the incredible women who are inspiring inclusion within the HVAC industry.

Mentorship in career development

Christyn believes mentorship is paramount to career development, especially for women

Christyn believes mentorship is paramount to career development, especially for women. It’s a resource she credits with advancing her career.

Christyn notes, “As a mother of three, I did not believe I could have a fulfilling career. It was my long-term mentor who showed me that being a mom did not make me less of an employee, but rather it provided me with experiences I could use within my work situations.”

Work experience

Paying this advice forward, Christyn became a member of the Johnson Controls Ducted Systems Mentorship Program Committee and joined both Women in HVACR and the Johnson Controls Women’s Global Network. She also leads the North American cohort of the Women in Leadership program.

She is passionate about connecting with other like-minded women who are working to make a difference within the industry. Outside of work, Christyn is thoroughly enjoying her current season of parenthood, especially when it leads to a great vacation.
