About Us

RMB Mechanical is a woman-, family-, and minority-owned HVAC contracting company that provides air duct cleaning and light commercial installation services in St. Louis County, Missouri and its surrounding areas.

Our CEO, Rochelle Bonty, has been in the construction industry for more than 11 years. Through those years, she spent most of her time tackling everyday problems in the field. She saw the need for more women like her in the industry; hence, she decided to start her own company.

Rochelle worked diligently to receive accreditation in her profession, start a business and follow her dream. 

We love every minute of our journey.
