High Standards: Why Quest Climate Dehumidifiers Are Essential for Quality Indoor Grow Operations

Coleman Retzlaff is Quest Climate’s National Director of Sales for Indoor Agriculture. With nearly two decades of experience in technical, operational, and sales roles, Coleman has been instrumental in shaping Quest’s reputation as a leader in dehumidification. His blend of technical expertise and customer-focused philosophy has helped Quest transform from an emerging brand to an industry benchmark.

“Resin-ating” with Cannabis Cultivators

Coleman began his career with Quest’s parent company, Therma-Stor, in 2006, where he worked as a technical advisor before transitioning to quality management and service roles. His ability to adapt quickly became a hallmark of his career. When he joined Quest Climate nine years ago, the company was still exploring its identity.

 “When I joined Quest, we were experimenting with the application of our technology in various industries, trying to find where we could provide the most value. It wasn’t until we turned our focus to agriculture that things really came together.”

That shift led Coleman to his first agricultural trade show—a moment he remembers vividly. “A young grower came up to me, excited, and said, ‘Quest — you guys are awesome!’ I thought, ‘This guy is thrilled about a dehumidifier?’ It was then I realized how deeply Quest resonated with the cannabis industry.”

Growing Green: Smart, Sustainable Savings

Quest Climate is dedicated to providing sustainable dehumidification solutions for its customers; it’s the principle that has guided the company’s growth. Coleman explains that efficiency in dehumidification boils down to a simple, but critical question: how much water can be removed per kilowatt-hour?

“That’s the number that matters,” Coleman says. “It determines what growers pay the power company every month. The less electricity our equipment uses, the more our customers save—not just financially, but environmentally too.”

This commitment to efficiency has made Quest synonymous with quality in indoor agriculture. Products designed with our patented Multi-Coil Refrigerant Recovery (M-CoRR) technology, for instance, have improved energy efficiency by about 30%. Advancements like these keep Quest at the forefront of the industry.

Quest’s reputation as a premium brand comes with a price tag, but Coleman is quick to point out the long-term benefits. “We’re not the cheapest, and we don’t try to be,” he says. “But when you look at the return on investment—energy savings, better crop performance, and reduced risk—the value is clear.”

He acknowledges that some customers initially choose lower-cost options, only to return to Quest when they encounter issues with performance or reliability. “It’s common for people to say, ‘We’ll upgrade later,’ but that often ends up costing them more in the long run,” Coleman notes. “Once they see the difference Quest makes, they’re ready to invest in quality.”

Pioneering the Future of Cultivation

Quest is not only meeting today’s demands, but also positioning itself as a leader in the future of indoor agriculture. Recent advancements include the adoption of EPA-compliant refrigerants and the integration of digital interfaces that simplify operation and troubleshooting.

“Our technology allows us to pull more water per kilowatt-hour than anyone else,” Coleman says. “And our new digital controls make it easier for customers to monitor and maintain their equipment. It’s about combining cutting-edge performance with ease of use.”

Coleman also sees an opportunity for Quest to influence sustainable building practices in agriculture. While certifications like LEED haven’t yet fully adapted to cultivation facilities, Quest is ahead of the curve, ensuring its products align with broader environmental goals.

“We’re early adopters,” Coleman says. “When the industry catches up, we’ll already be there.”


Guiding Customers to Success

Unlike many companies, Quest takes a collaborative approach to sales. Coleman and his team act as partners to their customers, helping them select the right equipment and optimizing its use for their specific needs.

“We’re not here to sell you more equipment than you need,” Coleman emphasizes. “We’re here to make sure your operation thrives. When our customers succeed, we succeed.”

This approach is especially critical in agriculture, where environmental control can make or break a harvest. Beyond preventing issues like bud rot, Quest’s technology allows growers to fine-tune conditions—improving yield, flavor, and quality.

“It’s not just about removing water,” Coleman explains. “It’s about creating the perfect environment for plants to thrive. With proper humidity control, growers can enhance oil production, terpene profiles, and even the color of their plants.”

Building a Legacy of Growth

For Coleman, Quest’s success is deeply personal. He’s proud of the company’s role in helping customers achieve their goals while advancing sustainability in agriculture. “We’re here to help people grow—literally and figuratively,” he says. “When our customers succeed, it validates everything we’re working toward.”

It’s this commitment to partnership, innovation, and efficiency that has cemented Quest Climate as a leader in the industry—and with Coleman Retzlaff’s guidance, its future looks even brighter.
