Commercial Retrofit & Installation Services in Charleston, West Virginia

Retrofitting old systems makes your equipment more energy efficient. By adding new technology and modernity to your systems, you bring your equipment up to current building codes and standards without the need to replace existing working equipment

Does your system use R11 or R22? Don’t be caught in the phase-out! 

At Casto Technical Services Inc., we help building owners get the most out of their aging systems. When it’s time to replace equipment that has become too expensive to maintain and cannot be counted on to provide reliable service. Our contracting team specializes in designing an upgrade that solves the problems of reliability and maintainability. Many mechanical systems were built into the facility and were never intended to be upgraded or replaced. We have the expertise and knowledge to meet the challenges of your building’s systems.

By partnering with multiple manufacturers and system suppliers, we are pleased to deliver building owners the best solutions for their needs. We base our solutions on value, reliability, energy efficiency, and of course, the needs of our clients. However, the value we deliver doesn’t stop after construction and installation. We partner with clients to provide training, support, and service to ensure your system is reliable, efficient, and lasts beyond it’s expected life.
