An unprecedented amount of regulatory changes has led to a host of challenges for the HVAC industry. Regulators want the industry to decrease greenhouse gasses and increase efficiency, but have left it to manufacturers to figure out a solution. Micro-Channel coils are that solution. These coils use less refrigerant, reducing the risk of greenhouse gasses leaking into the atmosphere. And, they transfer heat more efficiently across a smaller surface, allowing for smaller system footprints than their tube-in-fin counterparts.
