The cannabis industry is growing quickly as more states legalize marijuana for both medicinal and recreational use. And the industry has a high demand for HVAC services. More and more contractors are stepping forward to meet that need, and as with any new field, contractors need to make sure they are prepared for the specific needs and challenges it requires.

Advance Air in Freetown, Massachusetts, entered the cannabis industry a few years ago. The state fully legalized marijuana use in 2016. Advance Air President Karen DeSousa said the firm had a long history of commercial work, serving food distributors, specialized manufacturers, and surgery centers. This gave them experience in meeting specific environmental parameters — such as temperature, humidity, and air quality — in order to avoid negative impacts to patient health, product, income, and time.
