Groundbreaking Technology and Efficiency Defines The Lennox® Comfort System When you’re searching for the most cutting-edge HVAC technology on the market that delivers exceptional energy efficiency, look no further than Alan Heating Air Conditioning, Inc. in Elmhurst. We offer some of the most advanced heating and cooling products and features you can find, and they're all combined into one system: The Ultimate Comfort SystemTM from Lennox. The Ultimate Comfort System is comprised of innovative technological assets that work as one to take your comfort to an incredible new level, with excellent efficiency. Check out some of the features below. Precise Comfort® technology includes variable capacity and a variable speed motor, which operate like your car’s cruise control to ensure the system sustains consistent temperatures without temperature cycling. This keeps your home comfortable all day, while increasing overall efficiency. iHarmony Zoning® increases your home comfort and energy savings. It allows the Ultimate Comfort System to direct air to specific rooms of your home while limiting airflow to other areas. This personalizes your comfort by room and floor. The iComfort Wi-Fi® touchscreen thermostat makes iHarmony Zoning simple 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 anywhere, 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 allow the air to 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 substantially reduce 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 traditional 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.
