Commercial HVAC system keeps restaurant comfortable

Knueve & Sons takes great pride in offering full service Commercial, Industrial and Institutional HVAC. We have over 43 years of experience and a reputation for integrity in the commercial and industrial market of Northwestern Ohio. We will help you choose the equipment that best suits your needs, and then engineer each system for optimum performance, cost savings, long equipment life, quiet duct design and ultimate energy savings. Knueve & Sons is your one source for design and construction of any building or renovation project that requires sheet metal, piping, building automation, humidification, air quality and ventilation, exhaust or refrigeration.

Commercial Inspection and Maintenance

Effectively maintaining existing commercial systems is just as important as properly installing new ones. Our commercial maintenance and inspection programs for new or existing systems ensure your equipment is operating safely and efficiently. Upon completion of our inspection, we’ll provide you a detailed report of your systems performance.

Planned Maintenance Agreements include scheduled inspections and routine maintenance on the systems you choose.
