Who We Are
Core Mechanical Services is a commercial and industrial mechanical contractor serving Northern Indiana. Our team supports facilities across manufacturing, food processing, healthcare, education, and commercial environments and often in settings where uptime, safety, and precision are non-negotiable.
At Core, the work we do matters and so do the people doing it. From technicians working through extreme heat or winter storms to office and operational teams keeping projects moving behind the scenes, our people show care, passion, and pride in their work.
Our work ranges from complex system installations and custom mechanical builds to planned maintenance programs and emergency service response. Across every scope, our approach remains consistent: start with understanding, communicate clearly, execute with discipline, and stand behind the result.
Our Guiding Principles
We hold ourselves to more than standards; we live by values. Core Mechanical is built on accountability, teamwork, and respect. These principles guide how we work, communicate, and make decisions both internally and with our clients.
These are not marketing statements. They are standards we hold ourselves to on every job, every day.
