Founded in 1986 by Richard and Christine Schrader, Pro Heating & Air Conditioning, Inc. developed into a multi-million dollar corporation based on the principles of hard work, integrity and reliability.

Over the past two decades Pro Heating grew revenue from annual sales of $500,000 to more than $10 million in 2009. By year end 2010, Pro Heating included a full sheet metal and fabrication shop, construction division, service department, controls division and offers MEP CAD and design consulting, thus making us one of the most diverse companies in the industry.

Pro Heating & Air Conditioning was acquired by Jon J. Vanos in October 2010 and now operates as Pro Mechanical Services, Inc. Jon, longtime employee and former Vice President of Operations purchased the company from the Schrader’s, fulfilling the succession plan Rick and Jon had set forth years earlier. As Pro Mechanical moves into its next phase of evolution, we do so with a renewed commitment to excellence and customer service. Our offerings have expanded and will continue to grow in our newly formed Energy Group, Security Group and new Marketing Team. While the name may have changed, the core beliefs and values of the company have not.
