Your HVAC system is one of your building’s largest energy draws – consuming roughly 40% of your building’s energy expense. With a Daikin-designed energy audit, our team of experts will help discover where your opportunities lie: identifying energy conservation measures and spotting facility improvements may reduce your energy spend by 10 percent or more. The audit goes beyond the HVAC system to include an evaluation of lighting, occupant usage, and even windows and roofs. As a result of the process, you will gain perspective on potential energy savings and can see a steep change in building performance.


Unplanned repairs and escalating operations and maintenance costs can cause financial challenges for many buildings. Working with your team, we will provide the level of detail you need to be confident with the next ten years financial needs for your budgeting. Our Asset Management Assessment Tool includes a technical evaluation of your chillers, boilers, air distribution, pumps, and controls.


Our ventilation or load analysis will evaluate your current state, and our team’s counsel can help you achieve better building outcomes – for your budget, your building, and more importantly the people working, living, learning, and healing inside. If your systems are struggling to keep staff or customers comfortable – both in temperature and humidity levels—our team can help evaluate how to get your system to operate at optimal conditions.

Daikin System Services professionals help you get the most out of your building investment by optimizing your HVAC and other systems performance. Our service technicians can meet you where you are, with a suite of options customizable to your business needs. Connect with your local office today to identify the plan that’s right for you.
