Manufacturing Flexibility 
Flexibility is our key to satisfying a rapidly changing market. We meet this challenge using vertically integrated manufacturing. With less than 20% of our products' components being supplied by vendors, we have created a level of autonomy unparalleled in the industry. The results are timely deliveries, precise quality control, and competitive prices. ENVIRO-TEC products proudly carry the blue production label of the Sheet Metal Workers' Association, of the AFL-CIO, CLC.

Engineering and Research
For us, product integrity is a top priority.  That's why we've invested in one of the most sophisticated design and research laboratories in the industry.  All ENVIRO-TEC products are developed using the finest test equipment and sound evaluation facilities available.  As an AHRI participating manufacturer, our products are also tested and evaluated in strict accordance with AHRI standards.
