In-depth Comparison: Lennox vs. American Standard

Below is an in-depth comparison of Lennox vs American Standard;

Performance is the ability of a unit to do the job it is supposed to do. We are looking at how well the unit can heat or cool space in this case. Both Lennox and American Standard units are some of the most efficient on the market. Their appliances have a high SEER rating, resulting in lower energy bills and eco-friendliness.

However, due to a higher SEER rating of 28, Lennox units offer more efficiency than American Standard. This means that they can save you more money on your energy bills in the long run.

On the other hand, American Standard units are designed to perform well even under adverse weather conditions. They have a tough construction that can withstand high winds and freezing temperatures. This makes them a better choice for people who live in areas with extreme weather conditions.

2. Energy Efficiency

Energy efficiency is the ability of an appliance to convert energy into useful work. Lennox units are some of the most efficient on the market, while American Standard falls short in this category.

Lennox flagship scores a SEER rating of up to 28, making it one of the most energy-saving appliances. On the other hand, American Standard’s best model has a SEER rating of 22. This makes Lennox units up to 30% more efficient than their counterparts.

3. Compressor Options

When it comes to HVAC, the compressor is one of the most important parts. It is responsible for circulating refrigerant through the system. Lennox compressors come in two types; variable and modulating compressors.

The variable compressor is the most common type. It has two stages that can be turned on and off as needed. This makes it quite efficient. On the other hand, the modulating compressor is designed for precision cooling. It has an infinite number of speeds that you can adjust to meet the exact cooling needs of your home.

American Standard offers single, two, and variable compressor options. This gives you less flexibility when choosing a unit that meets your needs.

4. Noise Level

A noisy unit can be quite a nuisance, especially if you are trying to sleep or concentrate. American Standard air conditioners are some of the quietest on the market, with most models operating at less than 54 decibels.

Lennox units are also quiet, but they don’t match up to the noise levels of American Standard. Most of their models operate at around 59 decibels which is slightly higher than the industry average.

5. Condenser Fan Options

The condenser fan is responsible for circulating air over the outdoor coils. This helps to dissipate heat and keep the coils from freezing. Lennox offers two types of condenser fans; single and double fans.

The single-speed fan runs at a constant speed regardless of the weather conditions. This makes it quite noisy. On the other hand, the double-speed fan motor has two speeds; high and low.

This makes it more efficient as it can be adjusted to meet the cooling needs of your home. American Standard also offers two condenser fans; single and variable speed.

6. Warranties

HVAC systems are expensive, and you want to be sure that you are covered in case something goes wrong. Both brands offer a standard warranty of up to ten years on their units. This is quite good as it covers most of the major components of the air conditioner units.

However, the American Standard warranty edges over Lennox. The warranty covers the units for up to 12 years. The warranty is two years longer than the standard warranty offered by Lennox.

7. Price and Cost

Lennox units are some of the most expensive on the market. The high cost is because they are energy efficient and offer many features. American Standard units are also quite expensive, but they are not as pricey as Lennox. This makes them a good choice for people who want to save money on their purchases.

The price of a Lennox unit ranges from $1,475 to $3,775, while that of an American Standard ranges from  $1,235 to $2,625. However, when it comes to the installation, an American Standard unit’s cost is higher than that of a Lennox unit.

Lennox installation costs between $3,110 to $7,340  while American standard cost $5,800 to 8,000. The installation cost also depends on the unit’s size and type, making them vary. To ensure proper installation, look for a licensed HVAC installer.

8. Maintenance

Maintenance is also a factor you need to consider when making your purchase. American Standard units are easier to maintain as they have fewer parts that require regular replacement.

The only downside with American standard units regarding maintenance is the outdoor AC spine fin coil. The coil is difficult to keep clean and free of debris.

Lennox units are also easy to maintain. However, their parts are more expensive to replace than those of American Standard units. The expensive parts increase the overall cost of ownership.

9. Tax Breaks

A tax break is an incentive the government offers to encourage people to purchase energy-efficient products. Tax breaks are available for a variety of products, including HVAC systems.

Lennox and American Standard both offer tax breaks on their units. However, Lennox offers a larger tax break of $500 than American Standard, $300. This is because their units are more energy-efficient.

10. Durability

Your ac units should be able to serve you for a long time without the need for repairs or replacement. For this reason, durability is an important factor to consider when making your purchase.

American Standard units are more durable than Lennox units. This is because they are made from high-quality materials like heavy-duty steel panels that can withstand the elements. Additionally, the units undergo vigorous testing to meet the highest standards.
