A micro-channel coil is a type of Condenser Coil made of all-aluminum flat tubes with small internal channels. This design offers superior heat transfer and a smaller footprint compared to traditional copper-tube designs. We utilize these in some of our Central Condensers to help achieve high SEER2 Ratings. They are also lighter and require less refrigerant, making them more environmentally friendly. You can learn more about our coil technology on the Series Info page for our ducted systems. However, they require careful Coil Cleaning to avoid damaging the small fins. This advanced design is a hallmark of Professional Grade equipment. It is one of the many ways we maximize the efficiency of your Heat Pump System.
