Indoor Climate Control Expert, John Rocheleau is the sole inventor of all beekeeping equipment on the website: https://www.beefortressusa.com, including the Stainless-Steel and Hardwood Fortress Beehive and The Varroa Destructor Mite-Killing System.

John’s Background

John began his 43-year career in all-things-HVAC (Heating, Ventilating, Air Conditioning). That acronym is not comprehensive, since there are other elements of Indoor Climate Control that include:

  1. Humidity Control
  2. Refrigeration
  3. Air Cleaning
  4. Combustion Gas Venting
  5. Fuel Systems Storage & Delivery
  6. Other

John has been involved with all of these aspects of Indoor Climate Control (ICC), in design, installation and service/maintenance. While John does a comprehensive set of ICC systems work, and specializes on consulting, design and installation of upscale systems for high net worth building owners, he also serves as a legal consultant and Expert Witness up to the Superior Court level, and is an avid creative problem-solver and inventor of numerous hand tool, heating system components design and business systems designs. John is also a consultant to building owners and to independent inventors and a former president of New Hampshire Inventors Association that met at, then, the top Intellectual Law School in the world, Franklin Pierce Law Center, in Concord, New Hampshire.

John became a beekeeper in 2017 when his friend offered to pay for everything that he would need to keep honey bees, and he accepted. The same year, John’s first and only colony froze to death when it was -15-degrees F. Being a Heating systems expert, John solved this problem with his second prototype of a radiant-heated shelter for a single beehive, and it proved amazingly effective at keeping the bees warm and boosting brood by raising the temperature in March to incite the queen to lay eggs.

Since then, John has invested nearly $250,000 dollars on beekeeping equipment designs, culminating in the most recent deign, the Fortress Beehive and The Varroa Destructor Mite-Killing System that kills the majority of mites in a colony without a single chemical.

Letters of Recommendation

To whom it may concern,

I am writing a letter of recommendation on behalf of John Rocheleau. I’ve known John for about two years, he revised the HVAC system for my home and subsequently for my office. 

I’ve dealt with a number of people in construction including Architects, HVAC, Painters, Electricians and other members of industry. I have found that nearly all of them failed to perform up to the standards that they claimed they were capable of. John has been the lone exception to this.

As a Physician, I have spent many years in Academia. I think of John Rocheleau as a Professor of HVAC at an Ivy League University. Whenever I speak with him, he provides an in-depth lecture about various topics in the field of HVAC. I appreciate how he can dissect other people’s work and point out the mistakes they made and the reasoning behind their mistakes. I understand that John has designed and holds patents for many of the valves and other vital connections used in HVAC. To me this is extremely impressive not only because he was able to achieve this but also because he felt the motivation to do this. Simply put: John is brilliant and brings his work to an extraordinarily high standard. 

I believe most people have no idea about HVAC systems. Whenever my wife and I look at houses and ask the Real Estate agents about the home’s HVAC system, we always get the same blank stare followed by, “I can look into that for you.” Being able to control your environment at home or at work is crucial; not only for personal comfort, but also for productivity. Thanks to John, our home is far more live-able and our office is far more productive.

I recommend John Rocheleau to your attention without reserve, without constraint, and with my complete enthusiasm.
