Precise Comfort® technology includes variable capacity and a variable speed motor, which work like your car’s cruise control to ensure the system maintains consistent temperatures without temperature cycling. This keeps your home at an optimum comfort level all day, while enhancing overall efficiency. iHarmony Zoning® increases your family’s comfort and energy savings. It helps the Ultimate Comfort System direct air to specific rooms of your home while reducing airflow to other areas. This personalizes your comfort by room and floor. The iComfort Wi-Fi® touchscreen thermostat makes iHarmony Zoning nearly effortless to use. The most advanced thermostat Lennox has made, the iComfort Wi-Fi thermostat lets you monitor and adjust your temperature—and save energy—from any location, using your smartphone, tablet or laptop. Climate IQ® technology allows the Lennox Home Comfort System to adapt to your needs and your climate. In warmer areas, it changes airspeed to allow greater humidity control. In cooler climates, the system starts up more slowly to enable the air to absorb more heat before circulation. SunSource® solar modules can power your heating and cooling AND route any additional energy it generates into your home to run other appliances. This can significantly decrease your energy cost—potentially lowering bills by up to half. The XC25 is the world's first residential air conditioner rated above 26.00 SEER.* Compared to standard 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 buy. Like the XC25, this furnace may significantly decrease utility expenses. * 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.
