Top Features of the 4SCU23LX
Up to 23 SEER Efficiency Rating*
The highly energy efficient cooling mode on this heat pump can deliver more than 39% greater energy efficiency than a conventional 14 SEER single-stage air conditioner unit. SEER (Seasonal Energy Efficiency Ratio) rates the energy efficiency of your cooling equipment. The higher the SEER rating, the more efficiently your unit operates, saving your money on utility bills.

True Variable-Capacity Cooling
Rather than running at one or even two speeds, the 20LX Inverter-Driven Scroll Compressor changes its speed in small, precise increments and adjust cooling up and down like a dimmer switch. So temperatures are held exactly where you want them, even in extremely hot weather.
Omniguard® Total Corrosion Protection Technology
Our outdoor units feature Omniguard Total Corrosion Protection Technology, offering improved corrosion protection compared to traditional coils and preserving the life of your system for years to come.
MHT™ Technology helps transfer heat in and out of your home more efficiently. Featuring lanced coil fins for greater coil-to-air contact, rifled tubing for enhanced refrigerant flow, and a fan venturi cover to focus air flow over the coils to more efficiently remove heat in cooling mode and absorb heat from the air in heating mode. That means our air conditioners and heat pumps are designed to last longer and help ensure your home stays consistently comfortable.
Integrated Compressor Protection
The combination of both high- and low-pressure switches give additional reliability to each of our outdoor units. The high-pressure switch prevents operation if refrigerant pressures exceed safe levels, protecting the compressor. If your unit does not have enough refrigerant, the low-pressure switch prevents the unit from drawing in moisture and other contaminants while operating.
Heavy-Duty Compressor Blanket
Greatly reduces operating sound so your outdoor entertaining is not interrupted.
