Ensure safer HVAC system design and installation with the latest requirements in National Fire Protection Association NFPA 90B, Standard for the Installation of Warm Air Heating and Air-Conditioning Systems, 2021 Edition. This essential standard helps protect lives and property by reducing the spread of fire, smoke, and hazardous gases through heating, ventilation, and air-conditioning (HVAC) systems.

Heating and cooling systems are a vital part of modern buildings, but improperly installed or maintained HVAC systems can contribute to dangerous fire conditions. NFPA 90B provides comprehensive provisions for the construction, installation, operation, and maintenance of warm air heating and air-conditioning systems, including ducts, filters, air distribution systems, controls, and related components.

The standard applies to indoor HVAC systems, components, and air distribution systems in one- and two-family dwellings and buildings under 25,000 cubic feet in volume, making it an important resource for residential and light commercial projects.
