Advantages of Lennox Air Conditioning Products

Lennox has a long and well-deserved reputation as one of the industry’s most efficient air conditioning brands. When you invest in a Lennox air conditioner, you enjoy many benefits, including:

  • Commitment to quality: Each AC unit Lennox offers is the result of years of research and fine-tuning. You can be sure the air conditioner you purchase and install is built to last and has state-of-the-art features.
  • Quantum coil technology: Quantum coils use a proprietary aluminum alloy that protects against corrosion in indoor and outdoor environments. And because they weigh less than traditional copper coils, they’re more sustainable, reducing energy use during operation.
  • Indoor air quality: If any household member has allergies, asthma, or other respiratory issues, Lennox offers air quality solutions that work with your HVAC system to clean your home’s air and give you more control over your indoor environment.
  • Energy efficiency: Your HVAC system can represent up to 50% of your total energy use. Lennox offers ENERGY STAR®-qualified AC units that meet or exceed energy-efficiency standards.

What Is a Lennox Premier Dealer?

Premier Lennox Dealers are much more than service technicians. They have specialized training and experience working on Lennox products, having gone through extensive training and testing to become certified in installing, repairing, and maintaining Lennox HVAC products.

To qualify as a Lennox certified specialist, a technician must display expert knowledge and technical proficiency in a wide range of Lennox products and systems. They attend classes and hands-on workshops so you can be confident their work at your home optimizes your unit’s efficiency and meets Lennox’s high standards. No matter what problem you have with your AC, they’ll solve it quickly, effectively, and courteously.
