Our History

Quality 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.

But the family’s care and interest in the HVAC business didn’t end in that generation. After graduating with his Bachelors and Masters degrees in Mechanical Engineering from SMU, Jamal’s son, Mohammad, now runs the day to day operations at Quality Energy Systems. We strive for personal relationships with each and every one of our customers and ensure you will be speaking to either an owner or family member whose job is to take care of and make you happy every time you call. As a trusted air conditioning company, we are staffed by highly trained, NATE-certified technicians and Trane Comfort Specialists, some of which have been with us since day one. We are unique in providing 24-hour service, indoor air quality services, exceptional customer service and more. We guarantee customer satisfaction on the most energy efficient residential/commercial systems on the market today. From diagnosing a problem to creating custom heating and cooling solutions, Quality Energy Systems does it all.
