The EcoAir X Series 1220SD is the 12000 BTU indoor wall unit from EcoAir's R32 WiFi inverter split air conditioner range, bringing low-GWP R32 refrigerant, a SEER of up to 6.1 and a top-tier A+++/A++ energy rating to medium-sized rooms. As a split air conditioner indoor head, it cools and heats spaces of around 20 m² (roughly 600 BTU per m²), making it a versatile pick for medium living rooms, bedrooms and home offices. The X Series is engineered for quiet, hands-off comfort: ultra-quiet operation with a dedicated sleep mode suits bedroom use, while a 24-hour timer, memory function, intelligent defrosting and auto restart automate the everyday. WiFi connectivity and the supplied remote give precise app-based control. At just 9.5 kg, this is one of the lightest heads in the X Series indoor range, so wall mounting is straightforward. The move to R32 over older R410A lowers the global-warming potential, and the inverter compressor can save 30-50% on energy versus a non-inverter unit. Important scope note: this is the indoor unit only, so a matching X Series outdoor condenser and pipe kit are required to complete the system, fitted and commissioned by an F-Gas certified installer under UK rules.
