Comparison between Ducane and Lennox, Ducane Vs Lennox: Which To Choose?

Ducane Vs. Lennox Comparison

Purchasing HVAC for your home is a major decision because of the high cost of the equipment and installation. It is important to be guided with the right purchasing decision to ensure you will be using the unit for years to come.

Two of the most talked-about HVAC brands on the market today are Ducane and Lennox. Both have some of the most reliable, efficient, and durable HVAC systems designed to keep your home warm during cold winter days and cool during the hot season.

If you are trying to decide between one of these brands, consider the following points to make your choice easier.


Ducane is a subsidiary of Lennox and is the more economical product line. Although a lesser-known brand, it is slowly building its name by association with Lennox and through good reviews. Its relatively lower price compared to Lennox is what makes it attractive to the average consumer.

If Ducane is cheaper, does it mean it is less durable and reliable? Not necessarily. Ducane produces high-efficiency units, which means they use less power but deliver the same cooling and heating capacity as other standard-efficiency HVAC products.

Ducane's product lineup includes: 

  • Gas furnaces
  • Oil furnaces
  • Air conditioners
  • Heat pumps
  • Air handlers
  • Mini-split systems
  • Packaged units (all-in-one heating and cooling unit)
  • Traditional and Omniguard coils

When compared to Lennox products, the price range is a significant difference. For instance, a Ducane 13 SEER air conditioner can cost $1,649 at Walmart, while a fully installed Lennox 13 SEER starts at $2,300 in Lennox dealers. (Note, these costs may fluctuate.) 

As a side note, SEER means Seasonal Energy Efficiency Rating, which is the measurement of cooling efficiency. When looking for the SEER rating of air conditioners and heat pumps, the higher the better. Each US state has different SEER requirements, so it's best to ask your local dealer about the standard minimum in your location.

What makes Ducane different from Lennox products? Here are some of its significant features:

SEER Rating

The current minimum requirement by the government for a SEER rating is 13 but Ducane's air conditioners and heat pumps offer up to an 18.0 SEER.

Annual Fuel Utilization Efficiency (AFUE)

AFUE is the rating used for a furnace's heating efficiency. The U.S. minimum requirement is 78% but Ducane offers furnaces with an AFUE of up to 96%. This means more efficient heat for your home with less energy consumption.

Omniguard Technology

All Ducane units feature Omniguard Total Corrosion Protection Technology to guard against outdoor corrosive elements, extending the product's life. Ducane developed a new coil that is protected with Omniguard technology to resist corrosive elements coming from both outdoor and indoor air.

Longer Warranty

Ducane offers a default limited warranty of 5 years on parts, and 20 years on heat exchangers and other equipment. This covers your equipment for a longer period compared to other brands.

You should choose Ducane if:

  1. You're looking for a practical HVAC unit at a reasonable price
  2. You're looking for a furnace with a high AFUE at a fair price
  3. If you're looking for an air conditioner with a 13-18 SEER rating at a fair price
  4. You're looking for a practical and straightforward unit, without complex features but will get the job done
