Our Story

Cal-Neva Environmental Systems is a licensed mechanical and electrical contractor that specializes in commercial and industrial, wet and dry side HVAC installations and electrical projects. We carry many mechanical and electrical licenses as well as a general contractor classification. 

Cal-Neva Environmental Systems handles all aspects of HVAC construction from design to installation, commissioning of equipment and controls. We are a diverse firm that handles most of the construction in house, typically subcontracting less than 10% of the work to other trades, such as carpentry, roofing, insulation and balancing. 

Since Cal-Neva Environmental Systems started in 1976, our goal has always been Pride, Dedication and Quality and has a staff that is proud to support these goals.
