A Company is only as good as its People!

Grelak Mechanical has been a mainstay in Western New York State for more than 25 years.  The company was founded and operated by Randy Jasulevich from 1988 until the middle of 2014.  Randy used his decades of HVAC and Commercial Refrigeration experience to build the company into one the region’s largest and premier sales and service organizations.  From it’s modest start as a company with only a couple of trucks and servicemen, the company now boasts a multi-faceted team with the capabilities to handle even the largest rooftop and commercial installations.

A Changing of the guard...

In 2014, Grelak Mechanical saw its first leadership change in more than a quarter century as Randy began transitioning the company to its new ownership team of Paul Sullivan and Mike Reygers.  Together, Paul and Mike bring their 50+ years or experience in the field, committed to expanding the business while carrying on the company’s stellar reputation for superior quality and unmatched customer service.


With Randy’s ongoing guidance, Paul and Mike will lead the transition to the next phase of Grelak Mechanical’s evolution.  Their entire team is confident that its current customers will continue to enjoy the service levels they’ve come to expect, while new customers learn why Grelak Mechanical is the only name you need to know for all of your Commercial Refrigeration and HVAC needs.
