John began his Indoor Climate Control ("HVAC") career at New Hampshire Vocational Technical College, in Manchester, New Hampshire, in 1980. With his completion of a 400-hour Oil Burner Technology program he was hired by a ‘Mom & Pop’ legacy fuel company: Tenney Fuels, Inc., in Concord. Tenney’s focus was sales of quality fuel products and exceptional oil burner installations and service.
After 3-1/2 years at Tenney, John returned to school full-time at New Hampshire Technical Institute, in the Fall of 1984 and worked part-time for another legacy fuel company in Concord: Ferns Energy Centers. Both companies were founded in the late 30s and 40s as coal dealers, and fuel oil and kerosene was added to their products offering in the '70s. John expanded his job description at Ferns to include fuel delivery and was capable of delivering as much as 10,000 gallons per day.
By the end of 1988, John had worked for 2 other ‘HVAC’ companies, Desmarais Refrigeration and Bill Trombley Plumbing and Heating, but needed greater challenge, so started his own heating contracting company, Best Heating Corp.
In 1996, John became an independent inventor and in 1999 signed 2 License Agreements with Taco, Inc., a manufacturer of heating components, for his flanges and flanged valves associated with forced hot water heating system circulators. A few years of royalties allowed John to take a hiatus from HVAC work to finish the Business Management degree with Mechanical Engineering studies at NHTI. He graduated with a 3.92 GPA.
In 2002, John took his first sales job at Dowling Corp., in Portsmouth, the namesake of the town he grew up in in the 1960s, in Rhode Island. Within a year, Dowling sold the company and John took the valuable air conditioning and refrigeration experience he'd gained and returned to self-employment as Protech HVAC, LLC, offering residential and commercial HVAC system installations, maintenance and repairs.
As the economy began to turn down in 2008, Thayer Corp. (Auburn, ME) contacted John making an offer that he couldn’t refuse. As a Sales Engineer at Thayer, John had 2-3 times more sales estimates than any of the 6 other Sales Engineers due to his own Job Estimating system with origins dating back to Lotus 123. Having converted his system to Microsoft Excel, his estimating system became more efficient than Thayer's, hence, his greater sales success. In 2009 the recession had forced closed the doors of Thayer’s New Hampshire operation, so John returned to self-employment, again, under the name Protech HVAC.
In 2021, John’s revisions to his billing system were completed and Quote-Rite and Bill-Rite became their official names and have expanded to become Job Estimating, Job Costing and Job Billing systems that are highly accurate, precise, honest and professional.
Since 1998, John has received 10 patents on heating systems, hand tools and flanges, flanged valves, pipe fittings and valve components, and he enjoys the bragging rights of having the 2nd-greatest number of products by brand installed on his forced hot water heating systems. Only pipe & fittings makers can claim the 1st position.
Today, John still offers a complete spectrum of Heating, Ventilating, Air Conditioning, Refrigerating, Air Quality, Humidity Control, Gas & Oil tanks and Piping, Pool Heaters, Combustion Venting and Combustion Air and a plethora of other Indoor Climate Control mechanical systems, maintenance and repairs.
John also serves as a freelance Sales Engineering and Consultant to building owners and attorneys and as Expert Witness in District to Superior Courts, and Consulting to Independent Inventors.
John has also invented numerous honey bee equipment designs, including the only bear-proof bee hive in the world.
