Marcraft
Founded in 1921, Johnson Heater Corporation began as a mechanical contractor. From 1921 to 1950 we manufactured and installed HVAC systems for our customers. Between 1950 and 1970 we invented, perfected, patented and trademarked technology which is now known as the Johnson Air Rotation® System.
In the early 1970's, MarCraft® began producing highly Custom Air Handling Equipment. Johnson's knowledge and experience in air moving principles and temperature distribution, combined with the custom engineering expertise and manufacturing flexibility of MarCraft, gives us the ability to continually improve the technology and products that our founding engineers developed nearly a century ago.
