How can I control my energy expenses?Heating and cooling can make up a significant portion of your utility costs. The innovative and high efficiency heating and cooling products available from Lennox® can help decrease these costs. If you’re looking for a new heating and/or cooling system, look for products with high SEER ratings for air conditioners and AFUE ratings for furnaces. SEER and AFUE are a measure of system efficiency, and the higher the number, the more efficient the product. Other than purchasing a new home comfort system, consider these factors: 1. Is your product regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will work more efficiently after regular maintenance checks. 2. Do you need a zoning system? If there are parts of your home that are rarely used, a zoning system will allow you to heat or cool only the commonly used parts of your house. 3. Are you taking advantage of a programmable thermostat? According to the U.S. Department of Energy, programmable thermostats could reduce your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
