Groundbreaking Technology and Efficiency Defines The Lennox® Comfort System When you’re looking for the most cutting-edge HVAC technology on the market that delivers exceptional energy efficiency, look no further than Hammack Service Company in Richardson. 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 innovative technological assets that work as one 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 run like your car’s cruise control to ensure the system sustains consistent temperatures without temperature cycling. This keeps your home comfortable all day, while improving overall efficiency. iHarmony Zoning® increases your family’s comfort and energy savings. It allows the Ultimate Comfort System to direct air to certain rooms of your home while reducing airflow to other areas. This individualizes 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 any place, using your smartphone, tablet or laptop. Climate IQ® technology allows the Lennox Home Comfort System to become familiar with your needs and your climate. In warmer areas, it changes airspeed for 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 additional energy it generates into your home to run other appliances. This can dramatically decrease your energy cost—potentially reducing bills by up to half. The XC25 is the world's first residential air conditioner rated above 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 around. 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.
