Groundbreaking Technology and Efficiency Defines The Lennox® Comfort System When you’re searching for the latest HVAC technology on the market that delivers exceptional energy efficiency, look no further than WM J Kraus & Son in Keokuk. We’ve got some of the most advanced heating and cooling products and features you can find, and they're all bundled into one system: The Ultimate Comfort SystemTM from Lennox. The Ultimate Comfort System is comprised of innovative pieces of technology that all work together to take your comfort to an incredible new level, with outstanding efficiency. Take a look at some of the features below. 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 your ideal temperature and level of comfort 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 personalizes your comfort by room and floor. The iComfort Wi-Fi® touchscreen thermostat makes iHarmony Zoning easy to use. The most advanced thermostat Lennox has ever created, the iComfort Wi-Fi thermostat lets you monitor and change your temperature—and save energy—from anywhere, using your smartphone, tablet or laptop. Climate IQ® technology allows the Lennox Home Comfort System to adjust to your needs and your climate. In warmer areas, it changes airspeed to allow greater humidity control. In cooler climates, the system starts more slowly, letting the air absorb more heat before circulation. SunSource® solar modules can power your heating and cooling AND route any extra energy it generates into your home to run small appliances and electronics. This can dramatically lower your energy cost—potentially lowering 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 can 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.
