How can I reduce my energy costs?Lennox carries a variety of HVAC products with high efficiency ratings, which can help cut back the amount of energy they require to run. Aside from selecting products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can consider the following: Maintenance – ensuring your system obtains regular maintenance by a trained expert can keep your system running at its peak performance. Zoning – zoning systems enable you to only heat or cool only specific areas of your home, so you won’t have to pay to heat or cool spaces that you don’t typically utilize. Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home according to your schedule. They can be programed to provide the comfort you desire when you’re home, and increase or decrease the temperature while you’re gone, helping you save on heating and cooling costs.
