The Ultimate Comfort SystemTM from Lennox® brings you pioneering HVAC technology that delivers remarkable energy efficiency. The Ultimate Comfort System is a collection of advanced pieces of technology that all work as a team to take your comfort to an awesome new level, with extraordinary efficiency. Learn more below. Precise Comfort® technology incorporates variable capacity and a variable speed motor, which operate like your car’s cruise control to see that the system maintains consistent temperatures without temperature cycling. This keeps your home at your preferred temperature and level of comfort all day, while enhancing overall efficiency. iHarmony Zoning® takes your comfort and energy savings to a higher level. It allows the Ultimate Comfort System to direct air to specific rooms of your home while cutting back airflow to other areas. This adjusts 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 made, the iComfort Wi-Fi thermostat permits 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 fine tunes airspeed to give you more 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 lower 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.* When compared to conventional 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 find. Like the XC25, this furnace may markedly 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.
