Jack & Dede O'Farrell - Founders
Jack and Dede are from Chicago, Illinois, where they both graduated from Loyola University. After five years in the Air Force, living and traveling all over the country, they decided they wanted to relocate to the East Coast. So in 1972, Jack, Dede and their four children moved to Vermont. Jack worked for two local HVAC contractors as a service technician and service manager. In 1985, Jack and Dede decided to start their own HVAC service company, and thus, Mountain Air Systems, Inc. was born.
Originally Jack had two partners, Joe Monty and Toby Buxton. Toby's involvement with the company was brief, but Joe remained active with the company until 1992. By then, Tim and Liam were full-time employees and the groundwork for the family business was set. Business was good; Mountain Air had a trusted reputation, loyal customers and a workforce of skilled, happy employees.
At the end of 2005, Jack and Dede were both proud and happy to turn over the operations and ownership of Mountain Air Systems, Inc. to their capable and dependable sons, Tim and Liam. Jack and Dede remain on the Board of Directors and are active as consultants for the company. Most importantly, the culture of customer service that they established lives on and forms the foundation for the company that Mountain Air Systems is today.
Tim began learning the HVAC trade by working alongside his father during summers off from school. After high school, Tim attended the State University of New York at Delhi where he studied HVAC/R and electrical controls and graduated with an Associates Degree in Occupational Studies.
Tim joined the family business full time in 1988 as a service technician and HVAC/R installer. Later, Tim moved inside the office as the Service Division's dispatcher and coordinator.
In 2005, Tim, along with his brother Liam, purchased Mountain Air Systems from Jack and Dede. Tim ran the Service Division from 2005 until his untimely passing in 2011. Tim played a large roll in the formative years of Mountain Air Systems and helped grow the company to what it is today. Tim is greatly missed by his entire family and all of the employees at Mountain Air who worked alongside him.
