Lennox Debuts Space-Saving Side Discharge Heat Pump for Compact Homes

Lennox, a leading US HVAC manufacturer, has launched its innovative EL18KSLV Side Discharge Heat Pump—a compact yet powerful solution designed for homes with limited outdoor space. Ideal for zero-lot-line properties, urban residences, and narrow yards, this heat pump packs high efficiency and smart climate control into a space-saving design.

Key Features & Specifications

✔ Space-Saving Side Discharge Design – Fits in tight spaces where traditional heat pumps won’t
✔ Ultra-High Efficiency – Up to 19 SEER2 & 10 HSPF2
✔ Eco-Friendly Refrigerant – Uses R-454B (lower global warming potential)
✔ Variable-Capacity Operation – Adjusts output for optimal comfort & energy savings
✔ Wide Capacity Range – 2 to 5 tons (cooling: 22,000–56,000 Btuh, heating: 23,600–56,000 Btuh)
✔ Quiet Performance – Operates at 54–60 dB (comparable to moderate conversation)
✔ Warranty Coverage – 10-year compressor warranty (5-year parts warranty, extendable with registration)

Why This Heat Pump Stands Out

1. Perfect for Tight Spaces

Many urban and suburban homes struggle with limited installation space. Lennox’s side-discharge airflow eliminates the need for extra clearance, making it ideal for:

• Zero-lot-line homes

• Small backyards or side yards

• Properties with strict zoning regulations

2. Top-Tier Energy Efficiency

With ratings of up to 19 SEER2 and 10 HSPF2, this heat pump reduces energy bills while maintaining consistent comfort. The variable-speed compressor adjusts output to match demand, avoiding energy waste.

3. Future-Proof Refrigerant (R-454B)

R-454B is a lower-GWP alternative to traditional refrigerants, aligning with new EPA regulations and sustainability goals.

4. Reliable Performance in All Seasons

• Cooling Capacity: 22,000–56,000 Btuh

• Heating Capacity: 23,600–56,000 Btuh

• Handles extreme temps while maintaining efficiency

Warranty & Longevity

• 10-year limited warranty on the compressor

• 5-year limited warranty on covered components

• Optional 10-year extended warranty with product registration

Final Thoughts: Who Should Consider This Heat Pump?

The Lennox EL18KSLV is a game-changer for homeowners with space constraints who still want high-efficiency heating and cooling. Its sleek design, smart climate control, and eco-friendly refrigerant make it a strong contender in the residential HVAC market.
