How can I reduce my energy costs?Lennox has a host of HVAC products with high efficiency ratings, which can help reduce the amount of energy they require to operate. 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 think about the following: Maintenance – making sure your system obtains regular maintenance by a trained technician can keep your system working at its top performance. Zoning – zoning systems enable you to only heat or cool only certain 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 give you the comfort you desire when you’re home, and increase or decrease the temperature while you’re away, helping you save on heating and cooling costs.
