About us

Cryptic Air is a US-based manufacturer of premium linear slot diffusers and mud-in diffusers for residential and commercial HVAC projects.
Founded by Ben, a third-generation HVAC professional, Cryptic Air was built to solve the problems contractors deal with every day - long lead times, overpriced products from middlemen, and suppliers who don't understand the trade.

We design and manufacture every diffuser in our US facility in Florida using premium aluminum and airflow-tested engineering. Our product line includes the Cryptic Slot, a framed linear diffuser for standard installations and the Cryptic Pro, a mud-in diffuser for high-end projects where the HVAC needs to sit completely flush with the ceiling.

We work directly with HVAC contractors, general contractors, builders, and architects across the United States.
Our team offers free takeoff services, custom sizing at no extra charge, in-house engineering support, and 4–8 day shipping nationwide. Whether you need 10 diffusers for a retrofit or 500 for a commercial buildout, we handle the project from plans to jobsite.
