ABOUT US


Geostar Mechanical is a commercial contractor serving Northern IL and Southern WI that specializes in Heating, Cooling, Refrigeration and Plumbing. Why worry about calling one company for your plumbing needs, another company for your heating and cooling, another for your walk-in cooler and finally another company to test your backflow preventer devices. Geostar Mechanical is here to service all of your mechanical needs.

Geostar Mechanical was founded in March of 2008 by Wayne Blocker and his wife Jenny. Wayne had worked in the mechanical industry for multiple years and saw an opportunity to build a business on the philosophy of providing exceptional service at a fair price. Jenny is a successful Certified Point Accountant that manages the books for the business and is also a partner at The Benning Group managing payroll, tax documents and audits for companies across IL and WI.

As the business has continued to grow over the years there was also a need to bring in someone to help manage customer relations while also working on continuing to promote the company. Wayne hired his brother,Dan Blocker, to help fill this need and also become a partner in the business. Dan is the person you will talk to when you call Geostar Mechanical, so give him a call today.
