The Ultimate Comfort SystemTM from Lennox® gives you pioneering HVAC technology that delivers exceptional energy efficiency. The Ultimate Comfort System is comprised of advanced pieces of technology that all work as a team to take your comfort to an amazing new level, with extraordinary efficiency. Find out more below. Precise Comfort® technology incorporates 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 your ideal temperature and level of comfort all day, while increasing 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 reducing airflow to other areas. This customizes your comfort by room and floor. The iComfort Wi-Fi® touchscreen thermostat makes iHarmony Zoning a snap to use. The most technologically advanced thermostat Lennox has ever created, the iComfort Wi-Fi thermostat permits you to monitor and adjust your temperature—and save energy—from anywhere, using your smartphone, tablet or laptop. Climate IQ® technology allows the Ultimate Comfort System to adjust to fit your needs and your climate. In warmer areas, it changes airspeed to allow 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 route any surplus energy it generates into your home to run small appliances and electronics. This can noticeably 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 has the ability to 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 greatly 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.
