Protect lives and property from fire, smoke and gases spreading through dwelling and small buildings by designing and constructing them to the updated edition of NFPA 90B.

NFPA 90B: Standard for the Installation of Warm Air Heating and Air-Conditioning Systems provides the most up-to-date requirements to keep fire, smoke and gases from originating in and spreading through indoor HVAC systems in small buildings and 1- and 2-family dwellings.

The requirements cover construction, installation, operation, and maintenance of systems for warm air heating and air conditioning, including filters, ducts, and related equipment to protect lives and property from fire, smoke, and gases resulting from fire or conditions having manifestations similar to fire.
