If you’re in the Charlotte area, I’d prioritize firms that understand CEA/grow-room humidity loads, rather than a conventional residential HVAC installer. A greenhouse can generate enormous latent loads from plant transpiration, so the system needs to be sized and controlled around crop conditions.
For a CEA-specific engineering partner, I'd also look at borlaug-usa.com. They explicitly offer climate-control design, installation and commissioning, including heating, cooling, humidification and dehumidification, with crop-climate assessments.
For a serious commercial greenhouse, I'd ask installers about systems from manufacturers such as Desert Aire and Munters, rather than simply installing several residential-style portable dehumidifiers. Desert Aire specifically has CEA/grow-facility expertise, while Munters specializes in engineered air-treatment systems.
My first call would be SC DRYAIR, followed by UTR Systems or a CEA engineering firm such as Borlaug. When requesting quotes, give them greenhouse square footage, ceiling height, crop type, lights/heat load, irrigation rate, desired temperature/RH, and whether you already have HVAC. That lets them calculate the actual latent moisture load instead of guessing at tonnage.
If you tell me your greenhouse size, crop, target RH/temperature, and Charlotte-area location, I can narrow this down to 3–5 installers and tell you what type/capacity of dehumidification system I'd ask them to quote.

Dealing with fungal growth (like powdery mildew or Botrytis) means your humidity and Vapor Pressure Deficit (VPD) are out of balance. For controlled environment agriculture (CEA) and commercial greenhouses, industrial dehumidification isn’t handled by standard HVAC companies—you need agricultural-specific environmental control contractors, turnkey greenhouse builders, or specialized commercial mechanical contractors.
Options for system sourcing, engineering, and installation include:
If you need an end-to-end solution (design, structural integration, and equipment installation), specialized greenhouse engineering firms handle large-scale climate control retrofits:

Installing an industrial or commercial dehumidification system in a greenhouse or Controlled Environment Agriculture (CEA) facility is rarely a DIY plug-in job; it requires specialized mechanical engineering. Because greenhouses have massive latent heat and evapotranspiration loads , systems must be precisely calculated based on square footage, plant density, and local climate.
The types of professionals and companies who design, supply, and install these industrial systems include:
To help me point you toward the right type of contractor or system size, could you share:
- **AMS Industries, Inc.** - 9341 Adam Don Pkwy, Woodridge, IL 60517, United States - **Cooling Equipment Service Inc** - 141 Garlisch Dr, Elk Grove Village, IL 60007, United States - **Munters Moisture Control Service** - 615 Lunt Ave, Schaumburg, IL 60193
Yes. For a greenhouse with a significant moisture load, I’d look for a CEA/greenhouse climate-control integrator, not a conventional residential HVAC installer. The system needs to be sized around crop transpiration, irrigation load, nighttime conditions, dew point, airflow, and the existing heating/cooling system.
You may also want the installer to quote equipment from a specialist such as DryGair. Their systems are specifically designed for commercial greenhouses, indoor farms, propagation facilities and other CEA environments, with high moisture-extraction capacity and air circulation intended to prevent condensation and humidity-related disease.
YAKE is another specialist manufacturer focused on greenhouse and controlled-agriculture dehumidification. They emphasize engineering around the actual crop, moisture load, temperature/RH conditions, airflow, drainage, controls, and available utilities rather than simply selecting a unit by square footage.
Desert Aire is also worth putting on the bid list; it has substantial experience with CEA/grow-room dehumidification and works through HVAC/project partners.
Illinois even has a current technical-reference measure specifically covering stand-alone dehumidifiers for indoor agriculture, recognizing them as a distinct commercial/industrial application.
When you call, ask specifically for a site assessment and latent-load calculation, rather than a quote based simply on greenhouse square footage. Give them:
The goal should be to control dew point/RH and condensation at the crop, not merely make the air "feel drier." DryGair and YAKE both specifically address this distinction in their CEA engineering guidance.
If you tell me the greenhouse size, crop, location, and current temperature/RH (day and night), I can narrow this to 3–5 installers that are appropriate for your actual moisture load, rather than generic HVAC contractors.

Yes. For a greenhouse with fungal growth, I’d look for a CEA-specific HVAC/dehumidification engineer or contractor, rather than a standard commercial HVAC installer. The system needs to control humidity/dew point without simply overcooling the crop.
Dr. Greenhouse, Inc. — Probably the best starting point for a greenhouse/CEA project. They specialize specifically in HVAC and climate-management design for controlled-environment agriculture and report nearly 200 greenhouse, vertical-farm, and indoor-growing projects.
Desert Aire — Their GrowAire/GreenAire systems are purpose-built for indoor agriculture, combining cooling, dehumidification, airflow and controls. They have an independent-representative network that can help with system design and sizing, including California.
Anden — Focused on grow-environment humidity control. They explicitly provide design, delivery, installation, setup and service through HVAC/distribution partners.
The local search also surfaced some potentially useful mechanical contractors, although I would confirm CEA/greenhouse experience before hiring them:
If your greenhouse is in California, have the designer account for the California Energy Code's controlled-environment horticulture requirements. The current CEC guidance addresses dehumidification equipment and, for certain systems, integrated HVAC/chilled-water systems with heat recovery or desiccant systems.
My recommendation: start with a CEA engineer such as Dr. Greenhouse to calculate the moisture load and target dew point/VPD, then have a qualified mechanical contractor install and commission the selected system. Don't simply add several portable dehumidifiers—the moisture load from plants can be enormous, and poor placement/control can leave wet microclimates where fungus continues to thrive.
If you tell me your greenhouse size (sq ft), crop, typical temperature/RH, and whether it's in East Rancho Dominguez/another Southern California location, I can narrow this to 3–5 installers who are realistic candidates for your project and compare their specialties.

SC DRYAIR, LLC — South Carolina
Specifically listed for industrial dehumidification equipment, installation and field service. They're farther away, but their specialization is much closer to what you're describing than ordinary HVAC.
DryGair specializes specifically in greenhouse and controlled-environment agriculture dehumidification, including large-scale horticultural facilities. Their systems are designed around high moisture loads and air circulation throughout the growing area.
Desert Aire has substantial CEA experience and specifically works with grow-room/indoor-agriculture dehumidification. Their equipment can be engineered around temperature and humidity loads rather than simply adding a consumer-grade dehumidifier.
Surna provides facility design, equipment and support specifically for controlled-environment agriculture, including integrated temperature/humidity systems.
Dramm/Griffin CEA is another route worth investigating; its CEA materials describe engineered VIFRA greenhouse dehumidification systems and sizing around the facility's needs.
Since you're in the Charleston/James Island area, I'd start with Carolina Heat Pipe + Guimarin, while simultaneously contacting DryGair and asking for their recommended installer/integrator in South Carolina.
When you call, don't just say "I need a dehumidifier." Tell them:
"I have a greenhouse with excessive RH and fungal pressure. I need an engineered CEA dehumidification system, including moisture-load calculation, air distribution, condensate management, and integration with greenhouse temperature/VPD controls."
That will get you much closer to the right engineering group.
If you give me greenhouse square footage, ceiling height, crop, current RH/temperature, location, and whether it's sealed or naturally ventilated, I can narrow this down to the 2–3 installers most appropriate for your specific greenhouse and estimate the dehumidification capacity you'd likely need.
