Groundbreaking Technology and Efficiency Defines The Lennox® Comfort System When you’re trying to find the most cutting-edge HVAC technology on the market that delivers outstanding energy efficiency, look no further than Keystone Heating & Air Conditioning Co., Inc in Racine. We offer some of the most advanced heating and cooling products and features you can find, and they're all packed into one system: The Ultimate Comfort SystemTM from Lennox. The Ultimate Comfort System is comprised of very innovative pieces of technology that work as one to take your comfort to an amazing new level, with remarkable efficiency. Take a look at some of the features below. Precise Comfort® technology includes variable capacity and a variable speed motor, which run like your car’s cruise control to ensure the system keeps consistent temperatures without temperature cycling. This keeps your home at an optimum comfort level all day, while improving overall efficiency. iHarmony Zoning® increases your comfort and energy savings. It helps the Ultimate Comfort System direct air to individual rooms of your home while decreasing airflow to other areas. This customizes your comfort by room and floor. The iComfort Wi-Fi® touchscreen thermostat makes iHarmony Zoning simple to use. The most advanced thermostat Lennox has available, the iComfort Wi-Fi thermostat lets you monitor and adjust your temperature—and save energy—from any place, 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 alters airspeed to allow greater humidity control. In cooler climates, the system turns on more slowly, letting the air 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 dramatically decrease your energy cost—possibly reducing bills by up to half. The XC25 is the world's first residential air conditioner rated higher than 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 available. Like the XC25, this furnace may significantly lower energy costs. * 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.
