Inverter technology allows an HVAC system to vary its motor and compressor speeds in real-time rather than just turning "fully on" or "fully off." This results in much more consistent temperatures, quieter operation, and significantly lower energy bills. Our ACIq and MrCoolDuctless Mini Splits utilize this technology to provide exactly the amount of cooling needed at any given moment. By avoiding the high-energy "spikes" of traditional startups, inverter systems can save up to 50% on electricity costs. This technology is the key to the high SEER2 ratings found in Multi-Zone Systems. It also allows for much better humidity control because the system can run at low speeds for longer periods. You will find inverter-driven components across our Light Commercial Mini Splits and high-end central units. It is the single most important advancement in HVAC efficiency over the last decade.
