Great Guys is the Denver Metro Area’s Premier Choice for Heating, Cooling, & Electrical Service, Repair, & Installation
Who We Are
Nothing gives me more pride than taking excellent care of our employees and community. My daughter works harder than most men I have ever met, Great Guys, should’ve been called heroic women – in a male focused industry having a COO that is a woman, brings a great advantage to our company and the community we serve.
-MARCUS FAUTH, FOUNDER

Maddy Fauth co-founded Great Guys Heating Cooling and Electrical in 2018. She serves as the Chief Operations Officer of the family owned and operated business based out of Littleton. She grew up in Colorado and graduated from Grandview High School in 2010. Maddy has previously held operations related positions in hospitality and cannabis. These positions have created the foundation of success for her in a male dominated industry. Maddy has developed a strong sense of devotion to supporting her community through volunteering and supporting fellow members of the LGBTQIA+ community. This experience has given her a deep devotion for how nonprofits seek to improve lives for everyone in Colorado. She prides herself and Great Guys on building long lasting relationships with clients to address their property needs. With a focus on consumer education, service integrity, fair pricing, employee satisfaction and customer retention Great Guys has now become one of the fastest growing companies in the industry.
