About Us

At Quality 1 Energy Systems Heating & Air Conditioning, we strive to build lasting relationships based on trust and clear communication. We love getting to know the people we serve, so it’s only right that we share a little about ourselves.

Family Is Our Foundation

Our story began in 1989, when Jamal Gharbieh joined forces with his brothers Basem and Saad, to establish Quality 1 Energy Systems. From the beginning, our goal has been to provide other families with the same level of service we’d expect for our own. In an industry sometimes known for questionable ethics and business practices, we pledged to do things differently.

Using his expertise as a licensed professional mechanical engineer, Jamal Gharbieh quickly established rigorous standards for quality, workmanship, and service. We’ve upheld those standards by hiring talented, ethical people and partnering with the industry’s premier manufacturer to become a Trane Comfort Specialist.

A Business Built on Service

For decades, we’ve built up Quality 1 Energy Systems Heating & Air Conditioning without gimmicky marketing or advertising. Instead, we’ve focused all our efforts on serving local homes and businesses and contributing to community-based projects. We firmly believe in letting the quality of our work speak for itself.

In fact, we’re proud to say that we earn most of our business through direct word-of-mouth referrals. Gaining trust and building relationships takes hard work, but we’ve never been inclined to cut corners. Whether it’s earning customers or installing a new HVAC system, we’ve always been committed to doing things the right way. That includes offering speedy response times, prompt and professional service, and a 100% satisfaction guarantee on all our work.
