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.
A refrigerant that’s better for the environment.
This product is compliant with 2025 EPA regulations for lower global warming potential (GWP) refrigerants. The Lennox choice of 2025 Compliant Refrigerant has a lower GWP than its predecessor and is formulated to provide excellent, reliable performance of your system for years to come.

5/5
Very happy
November 23, 2025I'm really impressed with how quiet this unit is. Our 20 year old Coleman unit was sitting outside of our master bedroom, and it was very loud every time it turned on. We were just kind of used to it. The Lennox unit is installed in the same spot, and we literally can't even hear it when it's running. I didn't expect it to be THAT much quieter, but it's really nice. The A/C and heat both work as expected. I haven't seen a utility bill yet since it's been installed, but I expect that this will be much cheaper to operate than the unit it replaced.
Yes, I recommend this product.
