The brands use “iQ Drive” technology in their top air conditioners. The “i” stands for inverter compressor technology, the same technology used in mini-split air conditioners that are the quietest and most efficient ACs next to geothermal heat pumps. Other brands call this variable-capacity or modulating technology.
Most Maytag and Frigidaire AC models use micro-channel coils manufactured from aluminum. The aluminum coil is more resistant to corrosion than steel coils.
