Air Conditioning & Heating in St. Louis offers the most advanced heating and cooling products and features around, all used together in one system. The Ultimate Comfort SystemTM from Lennox® brings you pioneering HVAC technology that delivers exceptional energy efficiency. The Ultimate Comfort System is comprised of highly innovative pieces of technology that all coordinate to take your comfort to an incredible new level, with extraordinary efficiency. Find out more below. Precise Comfort® technology incorporates variable capacity and a variable speed motor, which function like your car’s cruise control to make sure the system maintains stable temperatures without temperature cycling. This keeps your home at your optimal temperature and level of comfort all day, while improving 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 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 designed, the iComfort Wi-Fi thermostat lets you monitor and adjust your temperature—and save energy—from anywhere you are, using your smartphone, tablet or laptop. Climate IQ® technology allows the Ultimate Comfort System to accommodate 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 push 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.* When compared to common 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 buy. 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.
