Top 9 Companies Advancing HVACD, CO2 Enrichment, and Climate Control in Vertical Farming & Greenhouses

Discover the top 9 companies revolutionizing HVACD, CO2 enrichment, and ventilation in vertical farming, greenhouses, and controlled-environment agriculture (CEA) for optimal crop yield and sustainability.

Indoor agriculture is reshaping modern food production, providing sustainable, high-efficiency alternatives to traditional farming. From HVACD systems and CO2 enrichment to advanced ventilation and climate control, industry leaders are driving innovations that help farmers optimize yields, reduce energy consumption, and maintain stable growing conditions.

With controlled-environment agriculture (CEA) becoming a cornerstone of urban farming, greenhouse cultivation, and vertical farming, selecting the right HVAC, CO2, and air circulation solutions is crucial for maximizing productivity. These technologies ensure that crops receive ideal temperature, humidity, airflow, and CO2 levels, preventing common issues like mold, plant stress, and uneven growth.

Below, we highlight nine industry-leading companies specializing in HVACD, CO2 systems, dehumidification, and smart environmental controls, making indoor farming more profitable and sustainable.
