Geostar was founded in 2008 primarily as a mechanical contractor offering HVAC, plumbing, and refrigeration services throughout Northern Illinois and Southern Wisconsin. The company now has a fleet of 24 vans operating within the education, healthcare, government, and hotel markets. In 2019, Geostar decided to start a controls division to align with their HVAC/R side of the business, and since that time, Jacob Blocker and Dave Baker have run that part of the business.

Shaun Lenz and Ronnie Schaeffer are business partners that met in 2013 and started Premier Energy Controls, based out of Rigby, Idaho in 2016. They predominantly install and service energy management systems in large campus applications, with a focus on higher education as well as commercial and industrial facilities. Lenz says he expects they’ll be expanding into the municipal and healthcare markets in the near future as well. In addition to Idaho, their service area also includes Montana, Wyoming, and Utah.

Based out of Detroit, Michigan, Brain Estes and his team at Mechanical Temp have been providing repairs and maintenance on HVAC and refrigeration systems for the past 9 years. Brian himself has been working in HVAC and refrigeration for over 19 years serving South Eastern Detroit, Northern Ohio, and Western Michigan.
