Firsthand Insights: What We Discovered
After a month of daily use, this unit excelled at rapid cooling—even on 90°F days, it brought our test room down to 72°F in under 15 minutes. During heating tests, the powerful heat pump maintained 68°F in a drafty living area with minimal noise. The Wi-Fi app was intuitive, letting us create schedules from our smartphones. Installation required a professional, but the modular outdoor compressor and indoor air handler fit snugly without bulky ductwork.
Energy Savings That Impress
Our meter readings showed a consistent ~1.1 kW draw at full blast—significantly lower than similar non-inverter systems. Over a 30-day summer trial, we recorded a 22% reduction in cooling costs compared to our old central AC.
