    • Utility

    For over four decades, Jim Abrams has been at the epicenter of every major change that has occurred in the HVAC industry… He’s known as the “Professor of Profits.” As a leading industry influencer and innovator, Jim has unprecedented experience throughout every inch of the world of contracting. He has taken his deep knowledge and understanding in contracting and business, and created a time-tested and proven 10-step formula for success. Now he has made this most closely guarded secret formula available to contractors everywhere seeking success via PRAXIS S-10™, the premier Success College for Contractors.


    In the 70’s, Jim led Trane’s entry into the residential HVAC business and took Trane’s “Five Saluting Men” nationwide. Perfecting the “Add-on” business, created a prosperous model for residential contractors.

    His unending entrepreneurial spirit led to the opening of his own business in the 80’s. They called him “The King of Replacements,” as he rapidly built the largest residential service company in North America. His innovations continued. Using unorthodox methods such as telemarketing, foot canvassers and direct mail he was the first contractor with over 10,000 service agreements.

    Next, Jim thought of a way to increase profitability. He entered the distribution business in order to supply his own company with equipment. Throughout this portion of his career, he shifted the marketplace from one that was considered too cold for heat pumps into one where heat pumps were a hot commodity. Jim was the first contractor to offer 10-year parts and labor, and the first contractor to private label HVAC equipment.

    In the 90’s Jim founded Contractors Success Group where he invented the contracting industry’s “Best Practice” concept. One out of two of the contractors that followed his wisdom, techniques and best business practices went on to become millionaires and multi-millionaires.

    Jim invented HVAC consolidation when he founded Service Experts. This was the first publicly traded HVAC Company, which grew to its peak of nearly a Billion-dollar residential service company. Then Jim took a very brief retirement – but he did not stay away for too long.

    Within the first decade of the 21st century, surpassing his first “Best Practice” organization, he launched what became the industry’s largest “Best Practice” organization, AirTime 500, Plumbers’ Success International, Electricians’ Success International and Roofers’ Success International.

    During this same time period, he built one of the largest residential service contracting companies in America, generating over $188 Million dollars in residential service revenue.

    Next, he introduced branding to the HVAC industry when he founded One-Hour Air Conditioning and Heating. With the rapid rise of this company, to his credit he has built two of the largest HVAC residential service companies in America.

    Almost all of the largest and most successful HVAC contractors in North America today have been clients and are using this business model created and developed by Jim Abrams.

    You can too, through his Guiding Principles for HVAC Success, now being taught at PRAXIS S-10™, the Success College for Contractors.
