We Make Buildings Work... Better!

Casto Technical Services has ended its relationship with Trane Company after more than 50 years of association. Soon after Harry N. Casto passed away on January 17, 2014, Nate Casto began discussions with Trane that ultimately ended with each company electing to go to market independently. As of February 1, 2015, Casto Tech will no longer be the Trane Commercial Sales Office.

Casto Tech will continue to focus on our core businesses of HVAC Service, Mechanical Contracting, Energy Services and Building Automation Systems (BAS). The knowledge and expertise of our associates remains our most valuable asset, and we look forward to providing our clients with the service and solutions that they have come to expect.

Casto Tech is a local, family owned business serving customers throughout West Virginia, Southeast Ohio, Eastern Kentucky, Southwestern Pennsylvania and Western Maryland. We are the market leader in commercial HVAC systems and service, and we will continue to invest in our associates to serve our existing clients and to gain new ones.

We are committed to the Vision - We Make Buildings Work...Better! To deliver on this mission we will partner with the best suppliers and manufacturers to bring our customers the most energy efficient solutions they need to own and operate their facilities.
