Why Should I Retrofit My HVAC System

Retrofitting provides enormous benefits to you and your building. Retrofitting enables you to improve your HVAC system without committing to a total replacement project. The benefits of retrofitting a chiller, cooling tower, or boiler include:

Energy Savings

Retrofitting an aging HVAC system is a quick way to resolve chronic high energy consumption. You can reduce your building’s energy consumption by up to 40 percent.

Increased Lifespan

Whole system replacements are not always feasible for our clients, but retrofitting can still extend the life of your HVAC system for several years.


Building occupants change all the time, and their needs change with them. Retrofitting old or damaged parts allows you to adapt to evolving tenant needs without a new system.

Improved Performance

Whether you need a high-performance HVAC system to keep customers and employees happy or to keep valuable assets in good working order, retrofitting is an excellent way to do so.

Prevent Issues Before They Arise

Disruptions in heating and cooling can be catastrophic for your business. Retrofitting older parts with new ones can help head off any potentially disruptive issues.
