Success Stories


Hale Farm and Village

Hale Farm’s HVAC units were dated and inefficient. CLS Mechanical Services replaced those units with high-performing equipment on time, on budget, and with no interruption to operations.

Game Entertainment-Freeway Lanes

The Parma facility had experienced unusually high natural gas bills for several months. CLS Mechanical Services was tasked with investigating the problem, recommending a solution and implementing that solution.

BDO Cleveland

BDO Cleveland’s former mechanical contractor recommended replacing problematic heating and cooling units at its Solon, Ohio offices. CLS Mechanical Services recommended a better way forward, saving BDO thousands of dollars.

Crossroads Adolescent Counseling

CLS Mechanical Services replaced a hard-to-find condensing unit, providing superior response time and better quality repairs at a better price.

What Others Say


“The professionals at CLS Mechanical are very personable, honest and see it through to the end that everything is done right. I like their personal consultative approach—they come out here and spend time working with me, rather than just communicating by phone. Lastly, CLS is highly responsive to any issue that may arise. That’s high on our list, and CLS is top-notch in that regard.”
