Upgrading an older HVAC or refrigeration system does not always mean a full replacement. Retrofitting adds new, energy-efficient components to your existing setup, dramatically improving performance and lowering your utility bills at a fraction of the cost of buying new. Our team specializes in identifying retrofit opportunities that deliver the same benefits as a new system—better efficiency, reduced energy consumption, and fewer breakdowns.

This service is ideal for building owners and facility managers in Montana who want to modernize their equipment without a major capital investment. Our process begins with a detailed energy audit and system analysis. We look at your current equipment, energy usage patterns, and operational needs. Then we recommend specific retrofits such as adding variable frequency drives, upgrading controls, installing more efficient compressors, or improving heat recovery. Our technicians handle the entire installation, testing, and commissioning.

Choosing CAS for your retrofit means you get experienced control specialists who understand both digital and pneumatic systems, so we can seamlessly integrate new components with older infrastructure. The result is improved system reliability, lower energy bills, and a smaller carbon footprint. Many of our clients see payback within months, not years. We proudly serve Billings and all surrounding areas. Contact us today to see if a retrofit is right for your business.
