Protech HVAC, LLC

Design, Installation, Service, Consulting, Expert Witness for virtually all "indoor climate control" and commercial refrigeration.

The owner of Protech HVAC, LLC, John Rocheleau, is a master HVACR system designer, service/installation technician, consultant to building owners and attorneys, expert witness in civil cases for building owners and their legal counsel in Small Claims, District and Superior Courts, and an independent inventor who has created industry-standard products that his competitors install. John became a self-employed HVAC contractor in 1988, and in 1996 began creating inventions of tools, flanges and valves for the trade which lead to several years of receiving royalties from 2000 to 2003. Protech HVAC was founded in 2004, after John worked for a year as a Sales Engineer for a larger company on the NH Seacoast. John took a position for a much larger company again in 2008, but the economy forced the company out of business and John returned to business as an HVACR contractor and consultant. In 2009, John began his 2nd invention development campaign and created many new products that he now uses on his own HVAC systems, which can be seen in the images above and at: www.protechhvac.com/inventions. Protech offers highly skilled and professional service to residential and commercial building owners.
