our start


Marathon Mechanical HVAC started out as a one man team. Ralph Walter Vensel began a small-time HVAC company that worked with Property Management Companies around town. After three short years, he ended up with over 45 Service accounts and he expanded into residential work on referrals. Since then Marathon Mechanical has sustained itself with a hard work and a pride of workmanship mindset. In 2007 3 year employee Jeremy Moreno took over ownership he was mentored by a long time HVAC/R Technician and business owner Peter J Frigo. To this day Marathon Mechanical still services a good majority of those customers from 1992.
