Retrofit & Control Upgrade

No matter how well HVAC equipment are maintained, it will eventually need to be replaced or upgraded, either because they reach their end of useful life or they simply no longer meet the requirement of the conditioned space. Oftentimes, retrofit projects do not meet owner’s expectation in performance, especially energy performance since installing contractor does not commission or optimize its operation after installation.
