Heating, ventilation and air conditioning systems, otherwise known as HVAC systems, are changing the way maintenance and engineering managers think about their facilities long term needs. With recent advancements in technology, HVAC systems are not better at improving the quality of air while also saving energy costs. According to Healthcare Market Leader Clay Seckman, “Decentralized HVAC systems might make more sense as an alternative to traditional centralized systems being replaced due to technological advances in controls and components.” HVAC systems are clearing the air about how to solve the energy needs of facilities growing demands for reliability and energy efficient air quality.
