How can I reduce my energy costs?Lennox offers a number of HVAC products with high efficiency ratings, which can help reduce the amount of energy they require to work. Aside from picking 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 receives regular maintenance by a trained expert can keep your system running at its best performance. Zoning – zoning systems allow 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 use infrequently. Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programed to offer you the comfort you desire when you’re home, and increase or decrease the temperature while you’re not around, helping you save on heating and cooling costs.
