    • “We live at the beach and had new AC installed but still could not figure out a way of keeping the humidity down. Reliable Ducts took several hours just to diagnose the issue and come up with a solution that was tailored to our needs and our budget. The installation was timely and professional as well as clean and fairly priced. We installed a whole house dehumidifier, ultra violet light to maintain mold free air and added vents to create air movement. It all works perfectly now. Thank you!”
