Lennox Furnaces

Efficient furnaces that save you money on heating bills.

Replace your furnace with a more efficient model for better, quieter heating and more cost savings in the future. Your furnace’s efficiency has a major effect on the amount of your monthly energy bill. U.S. If you plan on staying in your home for a few years, investing in a new, high-efficiency furnace will improve your comfort and your finances.
U.S. Department of Energy statistics show that heating and cooling account for about 56 percent of a typical home’s energy costs. The measurement of furnace fuel efficiency is called an Annual Fuel Utilization Efficiency (AFUE) rating. This is the ratio of a furnace’s annual fuel converted into usable heat. As of 2013, the Department of Energy requires new furnaces have an AFUE rating of at least 80 percent. Some of the better new models have an efficiency rating of up to 98.5 percent.

Aggressive Mechanical is proud to be a Lennox Premier Dealer, one of the top 100 Lennox dealers in the United States.
