Daizuki is a relatively new brand compared to HVAC giants like Trane and Goodman, but customer reviews are positive across the web. According to the company’s website, Daizuki was created “to offer green technology and beautiful design in Air Conditioners worldwide.” In pursuit of this goal, Daizuki offers a line of ductless mini-split systems run on only clean R-410a refrigerant. Blue Fin anti-corrosion technology—an air-dry coating providing protection to coils within the product—extends equipment life of every unit and maintains operating efficiency. All Daizuki products are certified through the Air-conditioning, Heating and Refrigeration Institute, and all products bear Intertek’s ETL Mark. This indicates that Daizuki units have undergone extensive independent testing and comply with all North American safety standards.
