Micro-channel heat exchange refers to the use of flattened tubes with tiny internal channels to increase the surface area for refrigerant cooling. This specialized engineering allows our Bravo Milano 24,000 BTU Universal Floor/Ceiling models to achieve higher SEER ratings. For homeowners utilizing a Dual-Zone configuration, this means faster cooling times even during high-noon sun exposure. Ensuring these channels remain clean and free of debris is easy when the unit is mounted on a Wall Bracket away from lawn clippings. Furthermore, our Installation Kits are designed to complement this flow by providing the exact copper diameters required. It represents a significant leap forward in thermodynamic efficiency for residential heat pumps. Optimized heat exchange is what allows our systems to provide such powerful heating and cooling.
