BTU tiering is a product strategy that offers different cooling power levels within the same model family to suit diverse room sizes. For instance, the Bravo Milano series spans from a 9k BTU unit up to the much more powerful 24k BTU Universal Floor/Ceiling model. This tiering allows customers to mix and match capacities within our Multi-Zone packages for a tailored fit. A common tiering choice for master suites is the 18,000 BTU Universal Floor/Ceiling indoor unit. All tiers are compatible with our standard Installation Kits, ensuring a uniform setup process regardless of power. By offering these specific increments, we ensure customers never pay for more cooling than they actually need. It simplifies the selection process for both homeowners and professional contractors.
