Building Commissioning & Retro-commissioning

Risk assessment and management are extremely important in the business world these days. Commissioning and retro-commissioning are two ways of monitoring a building for potential problems with the HVAC system. Just as you would take your vehicle in for a tune-up every so often, the same need goes for buildings. DiMarco & Associates, LLC can take care of both commissioning and retro-commissioning for you.



Commissioning an HVAC system is the process of verifying that the installation meets designer and manufacturer standards. It involves a visual inspection and operational test. Count on our commercial HVAC contractors for reliable commissioning and retro-commissioning services in the Twinsburg, Mayfield Heights, Cleveland Heights, Aurora, Beachwood, Chagrin Falls, and Solon, OH areas. After a new air conditioner or furnace installation, we will help put your mind at ease about the quality of the investment you just made as well as the assurance of safety and energy efficiency moving forward. For units that have been in use for some time, retro-commissioning will also help identify if any HVAC repairs are needed before they become a serious issue.
