Precise Comfort® technology incorporates variable capacity and a variable speed motor, which operate like your car’s cruise control to ensure the system maintains stable temperatures without temperature cycling. This keeps your home at your ideal temperature and level of comfort all day, while enhancing overall efficiency. iHarmony Zoning® takes your comfort and energy savings to the next level. It helps the Ultimate Comfort System to direct air to specific rooms of your home while lowering airflow to other areas. This tailors your comfort by room and floor. The iComfort Wi-Fi® touchscreen thermostat makes iHarmony Zoning simple to use. The most evolved thermostat Lennox has ever designed, the iComfort Wi-Fi thermostat allows you to evaluate and adjust your temperature—and save energy—from anywhere, using your smartphone, tablet or laptop. Climate IQ® technology allows the Ultimate Comfort System to adapt to your needs and your climate. In warmer areas, it adjusts airspeed to provide better humidity control. In cooler climates, the system starts up more slowly to allow the air to absorb more heat before circulation. SunSource® solar modules can power your heating and cooling AND move any surplus energy it generates into your home to run small appliances and electronics. This can dramatically reduce your energy cost—potentially reducing bills by up to half. The XC25 is the world's first residential air conditioner rated at 26.00 SEER.* Compared to common cooling systems, it could save you hundreds of dollars each year. Advanced variable-capacity technology makes the SLP98V one of the most efficient heating systems you can buy. Like the XC25, this furnace may significantly reduce utility bills. *SEER, or Seasonal Energy Efficiency Ratio, measures the cooling efficiency of your air conditioner or heat pump. A higher SEER rating means greater energy efficiency and more savings for you and the environment.
