Lennox Introduction

Lennox International is over a century old, founded in the United States in 1895. Mr. Lennox was the owner of a railroad repair business and built the first riveted steel furnace. In 1904, he sold his furnace business to D.W. Norris, who created the Lennox Furnace Company.

The company also created the first residential heating appliances using a forced-air furnace. Since then, the company has assembled some of the best air conditioner units in the country. Lennox has its headquarters in Texas. Yet, it has factories, dealers, and representatives in all states. 

In 1984, the Norris family created Lennox International Inc. This parent company oversees the Lennox Industries activities. Soon after, the brand expanded its production to commercial refrigerators as well. Nowadays, it manufactures a wide variety of HVAC products, including smart home appliances.

American Standard Introduction

The company was born in 1922 from two other companies: American Radiator and Standard Sanitary. The name “American Standard” came in 1967. Yet, the international name of the company is “Ideal Standard.”

In 1984, the company expanded further, acquiring Trane. In 2007, it became Trane, although it kept its old brand. Later, in 2008, Ingersoll Rand bought the company.

They build heat pumps, air conditioners, and furnaces using oil, gas, or electricity. This brand is recognized for manufacturing energy-efficient appliances. Units from the top lines rank up to 21 SEER (Seasonal Energy Efficiency Ratio). Those air conditioners are among the most energy-saving appliances on the market.

This brand uses several proprietary parts, which are famous for quality and durability. Because they manufacture most of their parts, they can offer longer warranties. They offer the most extended warranty for an air conditioner part at 12 years for its compressor.

Air Conditioner Parts

What American Standard Does Better Than Lennox

Their compressors have more speed options than Lennox. They build their own compressor, called Duration, a reputable compressor for its lifespan and capacity. Trane manufactures this compressor, and it deserves its name. This compressor can work at only 30% of its power. In comparison, Lennox compressors can’t work at less than 35% of their capacity.


Both brands offer a 10-year warranty on their appliances. Yet, some of American Standard’s parts are covered for 12 years under their warranties. This is the case for its compressor, Duration. Most American Standard’s components are manufactured by Trane, which is a very reputable manufacturer. Because they use many proprietary parts in their units, they offer longer warranties.
