A new standard from ASHRAE and the Air Conditioning Contractors of America aims to ensure a consistent minimal level of HVACR maintenance and inspection to preserve system integrity.

“Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems” is the first standard to address inspection and maintenance of HVAC systems, according to the American Society of Heating, Refrigerating and Air Conditioning Engineers.

 Robert Baker, chair of the committee that wrote the standard, noted that inconsistencies exist within the building industry when it comes to inspection and maintenance of HVAC systems, with some facilities following rigorous policies while others have adopted a “run-to-failure approach.”

“Consistent maintenance ensures that energy efficiency remains at design levels,” Baker said. “Where maintenance is neglected, energy costs rise significantly and equipment life drops dramatically. With HVACR systems responsible for about 60 percent of site electrical energy use, it’s imperative that we provide consistent maintenance and inspection to improve energy efficiency along with thermal comfort and indoor air quality. When systems are not maintained, indoor air quality, occupant comfort and energy efficiency all suffer.”
