"We strive to be a highly professional, technically superior, family of mechanical companies dedicated to excellence in delivery and execution for each of our valued customers."

Founded in 1974 as a small sheet metal shop, Interstate Mechanical grew over the last fifty years to become one of the largest and most well-respected full service mechanical subcontractors in Arizona. In 2024, Interstate Mechanical restructured by creating distinct companies for each of its three operating divisions - Construction, Facility Services and Maintenance. Each former division is now a separate company, and now called Evolution Mechanical Construction, LLC, Evolution Mechanical Projects, LLC, and Evolution Mechanical Service, LLC, with each company continuing to do business as "IMCOR". This change represents a significant milestone in our journey and reflects our aspirations for the future. Our goal is to maximize our strengths, resources, and expertise to create a more robust and competitive organization.

IMCOR Core Values


Our core values are the fundamental beliefs and guiding principles that define our identity, culture, and behavior. These values serve as a compass, shaping decision-making, actions, and interactions. IMCOR’s core values are deeply ingrained and have been part of our DNA for more than 50 years.


Safety is not just a priority; it's a shared mission that unites us in our dedication to creating a workplace free from accidents.  We are unabashedly committed to the well-being of our team and the success of our projects. We emphasize a culture where vigilance, communication, and proactive measures are integral to our daily operations. By taking personal responsibility for safety, we prioritize a safe working environment. Through ongoing training, awareness programs, and a steadfast focus on best practices, we are determined to achieve and maintain the highest safety standards.


We believe that success is the tangible outcome of meaningful teamwork. We place immense value on our connections with fellow employees, customers, subcontractors, and suppliers. It's not just about project success; it's about building enduring partnerships based on mutual trust. By connecting the right people, capital, and opportunities, we not only meet expectations but exceed them. This commitment to collaboration and synergy extends beyond transactions; it forms the foundation of long-lasting relationships that have stood the test of time.


Respect is not just a concept; it's a currency that we earn through transparency and trust. We believe that mutual respect fosters openness and honesty. We prioritize and embrace ideas with genuine consideration, creating an environment where every voice is heard and valued. Open and honest communication is the bedrock of our approach, fostering a culture where respect is not just a word but a shared experience. Our commitment to respect extends beyond interactions; it's a guiding principle in how we collaborate and seek improvement.


Integrity is consistency in actions, values, methods, measures, and principles. It involves a commitment to truthfulness, sincerity, and trustworthiness in one's words and actions. We firmly believe in the principle that no individual, no deal, and no client is greater than our collective commitment to integrity. Our dedication extends beyond any singular aspect— whether it be ourselves, a specific project, or a particular client. What stands paramount is our mission and our commitment to the values that define us, the success of our companies, the well-being of our community, and the principles for which we stand.


Our mission is to deliver unparalleled value in every project we undertake, a commitment to delivering tangible benefits that align with our customers’ goals. We offer cost-efficiency, reliability, innovation, tailored solutions, transparent communication, and a sustainable approach. We believe that success is a shared journey powered by value and quality and we endeavor to add measurable value to everything we do.


We are not only builders, we embody a philosophy of "Building Things" with passion and expertise. Our emphasis on zero accidents, together with the relentless pursuit of zero defects, underscores our dedication to safety and quality assurance. Our shared goal is to execute every project flawlessly from start to finish. Our combination of craftsmanship, innovation, and unwavering commitment to excellence sets us apart in the industry, establishing IMCOR as a trusted partner for clients seeking exceptional mechanical and plumbing solutions.
