Precise Comfort® technology includes variable capacity and a variable speed motor, which work 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 improving overall efficiency. iHarmony Zoning® takes your comfort and energy savings to a new level. It helps the Ultimate Comfort System to direct air to specific rooms of your home while cutting back 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 advanced thermostat Lennox has ever created, the iComfort Wi-Fi thermostat lets you watch and adjust your temperature—and save energy—from anywhere in the world, using your smartphone, tablet or laptop. Climate IQ® technology allows the Ultimate Comfort System to accommodate your needs and your climate. In warmer areas, it adjusts airspeed to provide greater 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 push 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 conventional cooling systems, it may save you hundreds of dollars each year. Advanced variable-capacity technology makes the SLP98V one of the most efficient heating systems you can have. 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.
