Features
Variable capacity, constant efficiency
This product offers variable-capacity operation, meaning it can adjust cooling output like a dimmer switch to perfectly match your energy use to your comfort needs. This also helps control humidity more accurately.
Class-leading heat pump technology
Our advanced cold climate technology delivers a greater amount of heat compared to traditional heat pumps, resulting in a feeling similar to the rich, warm comfort of a gas furnace—even during the coldest outdoor temperatures.
Use Less Energy. Save More Money
With efficiencies of up to 19.00 SEER2 and 10.00 HSPF2, the EL18KSLV can deliver significant energy savings. In fact, it can help cut your energy bills year-round. It may even help you qualify for energy rebates.
Small footprint with quiet comfort
The slim-design cabinet of the EL18KSLV allows for installation in even the tightest areas, making it perfect for space-constrained environments such as zero lot line homes. The side-discharge design also reduces sound levels for quiet, compact comfort.

System replacement with Lennox heat pump.
August 24, 2026Our old r22 system had a slow leak so we had to replace the entire system. The old system was very loud when we used the back deck and pool area and ran nearly continuously. The Lennox system is amazingly quiet and runs far less than the old one. In fact the attic fan (mushroom type near the peak of the roof) is much loader than the compressor. The house is kept very comfortable and the smart thermostat works great with the Lennox app on my phone. The entire system is recommended.
