Protect residential and small-building HVAC systems with the latest requirements in National Fire Protection Association NFPA 90B, Standard for the Installation of Warm Air Heating and Air-Conditioning Systems, 2024 Edition. This essential code helps contractors, engineers, inspectors, and facility professionals ensure heating, ventilation, and air-conditioning (HVAC) systems are installed and maintained safely to reduce the spread of fire, smoke, and hazardous gases.

Modern heating and cooling systems improve comfort and indoor air quality, but improperly designed or installed HVAC systems can contribute to rapid fire and smoke movement throughout a structure. NFPA 90B provides comprehensive guidance for the construction, installation, operation, and maintenance of warm air heating and air-conditioning systems, including ducts, filters, air distribution systems, controls, and related equipment.

The standard applies to indoor HVAC systems in one- and two-family dwellings and buildings with volumes up to 25,000 cubic feet, making it a critical resource for residential and light commercial applications.
