Our advanced defrost logic uses a reverse-cycle method to melt ice from the outdoor coil in minutes, rather than hours. This is critical for the Bravo Milano 18,000 BTU Universal Floor/Ceiling during cold snaps. In a Multi-Zone system, the indoor heads will briefly pause their fans to prevent blowing cool air during this cycle. Using a Ground Stand is highly recommended to allow the melted water to drain away from the unit and prevent re-freezing. Our Installation Kits provide all the necessary components for a successful winter setup. For extra-cold regions, check our Other Accessories for heated drain pans. This defrost capability is why Bravo Milano is a top choice for primary heating in many northern homes.
