Why do HVAC Systems for grow operations cost so much?



Why do I have to pay twice as much for HVAC from Manufacturer B compared to Manufacturer A?

We got a call from a prospective client the other day.  After 30 min on the phone they couldn’t grasp the importance of HVAC Systems for grow operations?

I really should just rephrase the question do you really want to risk million-dollar operation to save a few thousand dollars?

I think newbie commercial growers don’t understand the importance of HVAC Systems.  As cannabis consultants who been involved in 500+ cultivation operations.   We often see the tragedy that occurs when clients take shortcuts with their grow environment.

The environment is 70% to 80% of cultivation success.   I would say HVAC System and Good System Design is extremely important to commercial cultivation operation.

When growing high valve crop,  You want the following things in your system:

  • Reliability
  • Redundancy
  • Customer Service
  • Designed and Sized Correctly
  • Efficiency

Without going into much technical details.   In general, higher priced units will work much better in grow rooms.   Often the weakest link in most systems is HVAC Systems.   How many times have you seen HVAC go out in commercial buildings?   Plenty of Times.

Imagine HVAC failure when you $200,000 worth of crop growing in the room.  Do you really want to risk that?

Many newbie commercial growers often see HVAC units as typically same. They compare BTU tonnage and go with the cheaper unit.   This is a recipe for disaster.

Once you’re in production, you really can’t afford a failure, you got massive monthly overhead which needs to be paid for every month.

So how much time do you have to fix a broken or malfunctioning HVAC Unit while in full production?  A few hours at the most.


The best practice

Spend the time and money get the system designed correctly would professionals with years of experience.

Make sure they test the units thoroughly before entering production.

Always factor in your dehumidification needs.

Design for redundancy.

Plan for emergencies.
