Who we are

MID-OHIO Air Conditioning Corporation (formerly called Keen Air Service Division) was established in 1967 as an HVAC servicing contractor.   As an employee owned company, Mid-Ohio service technicians are not only qualified repairmen and installers; they are stakeholders in the growth of their company.  Mid-Ohio takes pride in it’s history of reliable service and fair pricing.  The company has relied on those attributes successfully for over 40 years, growing the customer base and expanding services as customer demand expanded.

We presently have over 30 fully equipped service and construction vehicles, a complete Construction Department with design/build capabilities, and a Service Department that provides preventive maintenance and repairs.


Facilities we work at

Mid-Ohio Air Conditioning offers single source responsibility for design and construction of heating, ventilating and refrigeration projects. Our professional engineering staff works closely with architects, building managers, general contractors and building owners to evaluate specific needs for each project. We then design the most economical and energy efficient system available, prepare and submit engineering documents, establish and maintain construction costs, and provide a quality installation by experienced craftsmen.

Mid-Ohio Air Conditioning’s engineering staff utilize their experience and expertise to analyze existing mechanical systems, identify problems and provide effective solutions. Our staff also provides energy analysis and retrofits and will work with building owners on indoor air quality to provide a healthy working environment.

From conceptual design, installation, start-up and maintenance our design/build team delivers the kind of top quality performance you can expect from a full service mechanical contractor.
