The Lennox 4–5 Ton Side Discharge Ducted Heat Pump System is a high-capacity, energy-efficient solution designed for large residential homes and demanding comfort needs. With a flexible 4–5 ton (48,000–60,000 BTU) capacity, this system delivers powerful heating and cooling performance while maintaining consistent indoor comfort.

Built on Lennox’s advanced side discharge platform (Elite Series EL18KSLV), this unit features a compact horizontal airflow design, making it ideal for space-constrained installations such as narrow side yards or zero-lot-line homes.

The system is powered by a variable-capacity inverter compressor that continuously adjusts output based on real-time demand. This ensures precise temperature control, improved humidity management, and significantly lower energy consumption compared to traditional systems.

With efficiency ratings up to ~19–19.5 SEER2 and 10 HSPF2, the unit offers excellent energy savings and may qualify for ENERGY STAR® incentives.

Designed for quiet performance, the system operates at sound levels as low as ~54 dB, making it one of the quietest options in its category.

It uses next-generation R-454B refrigerant, which reduces environmental impact while maintaining strong performance.
