Lennox SL25XPV Heat Pump

The most precise and efficient heat pump you can buy, now featuring Lennox TruHeat Performance

Lennox SL25XPV Heat Pump

Truer, Richer Warmth

Lennox TruHeat Performance 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.

Consistently Perfect

Precise Comfort® technology adjusts heating and cooling output in precise and minute increments to perfectly match your energy use with your comfort.

Our Uncontested Quantum™ Coil

With years of rigorous testing under the most extreme conditions, our Quantum Coil—featuring a proprietary aluminum alloy exclusive to Lennox—is designed to weather the harshest elements.

Beyond Quiet

This heat pump has been engineered with a variable-capacity compressor which allows it to primarily run in low speed—drastically minimizing the sound of air kicking on or off inside the home. Add in a special sound-dampening system to absorb outdoor noise and you can be assured it operates at a noise level that is, quite simply, unheard of.

We have higher standards.

Year after year, leading institutions choose to award Lennox for its innovative initiatives in product design which helps homeowners define what perfect air means to them. Below you’ll find a recognition this product has received.
