Waibel Energy Systems, Inc

Waibel Energy Systems has operated from Vandalia for more than three decades, delivering HVAC, plumbing, building automation, and security services to commercial and institutional clients across the Dayton region. With a rating of 4.6 stars drawn from twelve customer reviews, the company employs a team of over 120 associates and manages more than eight million square feet of building space for clients in healthcare, education, manufacturing, and property management. The contractor maintains a commercial parts distribution operation that stocks components typically unavailable to homeowners without contractor licensing, and offers twenty-four-hour emergency response for clients with service agreements.

The contractor distinguishes itself through an analytics division that has generated twenty-five million dollars in combined energy savings and utility rebates for client facilities. Their building automation expertise centers on Niagara software implementations, with more than one thousand active instances monitored across their service territory. A healthy-building division addresses indoor air quality through specialized testing and consultation services, a capability that proved particularly relevant following the COVID-19 pandemic. The company also operates a commercial plumbing division and provides integrated security systems including door access controls and camera monitoring.

Customer feedback highlights responsive emergency service, with multiple reviewers noting that technicians arrive same-day during urgent situations. Jessica N. specifically praised the team's willingness to go beyond standard repairs, and Brad Stumpf's review emphasizes the company's quick turnaround on requests. Rebekah Fairhurst's unexpected encounter with two Waibel employees who stopped to assist with a flat tire illustrates the company's culture beyond commercial transactions. Jason Shafer and J Klenke separately mention the staff's competence in energy management and general HVAC knowledge as primary reasons for their five-star ratings.
