Our History
Founded in 1985 by Curtis Scheetz, Total Environmental Management, Inc. (TEM) began as an emergency and temporary air conditioning provider in Southern California.

Today, headquartered in Anaheim, TEM operates the largest HVAC rental inventory on the West Coast. Our facility includes in-house welding and custom fabrication, allowing us to deliver tailored, turnkey solutions for clients across the western U.S.
With more than 40 years of experience, TEM has tackled everything from earthquake response to cooling the Olympic torch—always with customer service at the forefront. Our 77-member team remains focused on finding, engineering, or building the right solution for every project.
