Maytag’s PSA4BI air conditioner with the IQ Drive Control is Maytag’s top-of-the-line central air conditioner and part of the brand’s M1200 series. When paired with the proper furnace or air handler, it can achieve an efficiency of up to 24.5 SEER. The PSA4BI was rated a “Best Buy” by Consumers’ Digest and is one of Energy Star “Most Efficient” air conditioners for 2014.
All central air conditioners use a compressor to pump refrigerant through the system, and to increase the pressure on the refrigerant to raise its temperature. Most high-efficiency air conditioners use a type of compressor known as a scroll compressor. The PSA4BI is different — it uses a rotary compressor, which was originally designed for window-mount and mini-split air conditioners. Most central air conditioners cycle on and off frequently as they try to maintain the temperature in your house. This frequent cycling is inefficient. The inverter-driven rotary compressor design used in the PSA4BI runs (almost) continuously, allowing it to run more efficiently.
IQ Drive Control
The IQ Drive Control is Nordyne’s software for communicating between different components of your home’s heating and cooling system. When connected with other IQ Drive-compatible components, the IQ drive can track diagnostics (should a problem develop) and increase the efficiency of the entire system through better coordination.
Noisy vs Quiet
The PSA3BI is considerably quieter than many of the units that it is compared to, emitting as few as 59 decibels of noise.
