Lennox Residential HVAC announced the launch of the Elite Series EL18KSLV Side Discharge Heat Pump, combining efficient performance and space-saving design.

The EL18KSLV Side Discharge Heat Pump features a narrow cabinet designed for easy installation in space-limited areas, such as zero-lot-line homes. Its variable-capacity design adjusts output to align with household comfort needs while supporting energy efficiency. With ratings up to 19 SEER2 and 10 HSPF2, the unit is built to help reduce energy use and may contribute to lower utility costs throughout the year. A precision-balanced, direct-drive fan enables sound levels as low as 54 decibels, comparable to an electric toothbrush.

The EL18KSLV Side Discharge Heat Pump is compatible with multiple Lennox smart thermostat product lines, allowing users to manage settings through various smart home platforms. The unit qualifies for the Energy Efficient Home Improvement Credit, a federal incentive for high-efficiency home upgrades. Additional utility or regional incentives may apply. The EL18KSLV Side Discharge Heat Pump is available to purchase through local Lennox dealers. For details, visit www.lennox.com.
