Maintain Your Buildings the Right Way Through the ANSI/ASHRAE/ACCA Standard 180 for Quality Maintenance

The ANSI/ASHRAE/ACCA Standard 180 for Quality Maintenance established proper practices for inspecting and maintaining commercial building HVAC systems. The American National Standards Institute (ANSI), the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), and the Air Conditioning Contractors of American (ACCA) developed and support these standard practices for inspecting, maintaining, and optimizing the energy efficiency, thermal comfort, and indoor air quality delivered by your commercial HVAC systems. The Standard 180 for Quality Maintenance outlines inspection and maintenance tasks that are designed to allow proper accommodation to the size, design, scope, and complexity of a system serving each facility.

Diagnostic Tool

Participating contractors with the NYSERDA HVAC Business Partners use a specialized diagnostic tool that allows them to specifically measure, diagnose, and remedy refrigeration charge and airflow. This testing and measurement is included within a complete Quality Maintenance checklist for your condenser, compressor, evaporator, coil, heater, and electric wiring in your rooftop units.

Benefits

A properly maintained commercial air conditioning unit not only optimizes your unit's performance but also keeps building occupants comfortable and safe. Properly inspecting and maintaining your AC unit makes it run efficiently, reduces your energy costs, extends the lifespan of that unit, and decreases your risks and costs for emergency service calls and repairs. A clean, optimized system minimizes risks of airborne contaminants, mold, mildew, and dust. Most importantly, a properly maintained unit gives you peace of mind.

In particular, the ASNI/ASHRAE/ACCA Quality Maintenance provides all of these benefits to you:

Incentives

Incentives [PDF] are available to offset additional costs associated with the purchase and installation of approved equipment. NYSERDA promotes the Consortium for Energy Efficiency (CEE) Tier 1 energy efficiency specification for commercial HVAC units. These efficiency levels are approximately 22% higher than the current federal minimum standards. Installing equipment that reaches CEE's Tier 2 specifications provides even greater energy savings for your building. The Equipment Availability Table Link opens in new window - close new window to return to this page. also includes a number of AHRI approved models.
