Hospital and Healthcare Facility HVAC Systems

Hospitals and Healthcare Facility HVAC systems

Spaeder understands that a well-functioning HVAC system isn’t just about comfort; it’s about creating an environment that fosters exceptional performance. In hospitals and other medical facilities, it is imperative for medical personnel to receive proper ventilation to help create a clean environment for their patients. To ensure the highest quality of air within a hospital, we adhere to the latest requirements of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). These systems are carefully engineered to meet infection control criteria, while also being reliable, efficient and low-maintenance. Furthermore, we know it is imperative for hospitals–especially in the middle of an emergency–to be firing on all cylinders. This is why Spaeder offers 24/7 emergency service to help keep hospital HVAC systems up and running, 24/7.
