About Us

Our History

Quality 1 Energy Systems was established in 1989 by Jamal Gharbieh, licensed professional mechanical engineer with the help of his two brothers, Basem and Saad. Focusing on exceptional customer service and superior quality, they were able to grow and advance for more than 20 years. Through word of mouth referrals and community-based projects, they gained the trust and loyalty of customers throughout the Dallas/Fort Worth area.
