EL18KSLV Heat Pump

Mid-efficiency, slim-design, variable-capacity, cold climate heat pump

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.
