There are four places where problems with HVAC systems originate:

  • At the Design Table
  • During Installation
  • During/Following Maintenance & Repair
  • As a Result of Lack of Maintenance

If the HVAC system isn’t properly designed, the system will never run properly.

If the HVAC system isn’t installed properly, it will never run properly.

If the Maintenance & Repairs to the HVAC system are not performed correctly, the system will never run properly.

If the HVAC system owner doesn’t hire an experienced, knowledgeable and competent HVAC Service company to perform manufacturers’ recommended procedures/practices, then the owner should not complain when the system fails, and fail it will.

Protech HVAC, LLC, in Center Sandwich, NH Designs, Installs, Repairs and Maintains all HVAC systems types, including the systems that don’t fall under Heating, Ventilating, Air Conditioning (HVAC). We also Design, Install and Maintain & Repair Humidity Control, Air Filtration, Refrigeration, Exhaust Fans, Commercial Ranges/Burners, Snow-melt, Fur Closets, Wine Cellars, Pool Heaters, Whole-House Fans, Bath Exhaust, Water Filters & Shallow Well Pump Repair, Fuel Tanks & Lines & Gas-Piping and anything else in the Indoor Climate Control aspect of the building trades.

Here’s a brief list of actual things we do:

  1. Design all Indoor Climate Control Systems
  2. Install all systems
  3. Maintain & Repair:
    • Oil-fired burners, furnaces and boilers (steam and forced hot water) and water heaters
    • Gas-fired burners, furnaces and boilers (steam and forced hot water) and water heaters
    • Fuel tanks/lines
    • Gas Piping
    • Forced Hot Water Heating System water PH & Cleaning
    • Incorrectly-designed duct and piping systems
    • Heat Pumps
    • Water Filter Changes

    • And a whole lot more!

We also troubleshoot all systems to determine what is or isn’t wrong. Just as we do failure analysis to determine not only what is wrong, but who-dunnit.

And when others have failed at these things, we help legal teams create a big picture of the case and then provide the fine details in consulting and on the witness stand in Small Claims, District and Superior Courts as “Expert Witness.”

In other words, if it involves water, air or fuel, we do it all, all over New Hampshire!

John Rocheleau has served in several different roles in the Indoor Climate Control industry, often referred to as "HVAC" since Tech School, in 1980. He started his 45-year career (as of 2025) in the filed as an oil burner service technician and systems installer at Tenney Fuels, Inc. and Ferns Energy Centers, both in Concord, New Hampshire. He also delivered Kerosene and #2 Fuel Oil at Ferns. From 1987 to 1988, John had 7 job changes as he looked for something meaningful, rewarding and worthy of career status. Finding nothing that suited him, he went in business for himself. https://protechhvac.com From 1996-1999, John invented virtually everything that connects to forced hot water circulators in residential and light commercial applications - flanges and valves - that he licensed to Taco, Inc. in 1999. These inventions have become known as "Webstone Valves" and were also produced, and/or sold by Watts, Legend Valves, Nibco and too many others to mention. John is writing a book about these inventions, the industry players involved with bringing them to market, and millions of dollars owed to John. https://maverickinventor.newhampshireconnections.com John went on to invent his own mechanical product line, digital and printed business systems. https://rite-forms.com Becoming a beekeeper in 2017, John has invented beekeeping equipment, including the most advanced beehive ever created and the only bear-proof beehive in the world. John has likely done more in beekeeping product development than anyone in modern times in the beekeeping equipment industry. https://beefortressusa.com John has also developed numerous designs of dog, cat, monkey exercise and play toys - https://doggyskeet.com John also involves himself with property management and maintenance and assisting residential and commercial building owners with myriad projects. https://go-to-guy-nh.newhampshireconnections.com John is a consultant to independent inventors and speaker on such topics.
