Our Legacy of Expert Care
Duree HVAC is a professional heating and cooling company serving residential and commercial customers across Southern California. Our mission is simple — deliver reliable, safe, and efficient HVAC solutions with honest service and high-quality workmanship.
Founded in 1992, Duree HVAC built its foundation on hard work and technical craftsmanship in Sai Gon, Viet Nam.
After years of hands-on experience in the HVAC industry, the founder immigrated to the United States with a vision to continue that legacy and create new opportunities through honest, high-quality work.
Â
Like many immigrant families, the journey began with determination, long hours, and a strong belief in building a better future. With industry knowledge gained in Vietnam and real-world experience in the U.S., Duree HVAC was established to serve local communities with dependable heating and cooling solutions while upholding the values of responsibility, safety, and professionalism.
Â
Today, Duree HVAC proudly represents the spirit of immigrant entrepreneurship — combining international experience with American standards — and is dedicated to delivering reliable HVAC services to homes and businesses across Southern California.
