Advantages of Lennox Heating Products

Lennox has a long and well-deserved reputation as one of the HVAC industry’s most efficient heating brands. When you invest in a Lennox furnace, heat pump, or boiler, you enjoy many benefits, including:

  • Commitment to quality: Lennox furnaces are among the quietest and most efficient heating systems you can buy. Engineered for perfect warmth and savings, they save you money, feature state-of-the-art technology, and enjoy a long life span.
  • Quantum coil technology: Lennox heat pumps feature Quantum coils that protect against corrosion in indoor and outdoor environments. The specialized aluminum alloy weighs less than traditional copper coils, is more sustainable, and effectively reduces energy use during operation.
  • Indoor air quality: For family members with allergies, asthma, or other respiratory issues, Lennox manufactures air quality solutions that work with your HVAC system to clean your home’s air, giving you more control over its indoor environment.
  • Energy efficiency: Your HVAC system can make up to 50% of your home’s total energy use. Lennox offers ENERGY STAR®-qualified furnaces that boast an efficiency rating of up to 99%, meaning they convert nearly every last bit of energy they use into heating your home.

Experience the benefits of a Lennox system for yourself! Call (833) 232-4328 or contact us online to schedule an installation in the Evansville or Louisville areas.
