What Goodman Does Better Than Lennox in Air Conditioning

In this section, we’ll show where Goodman has some clear benefits over Lennox.


Goodman products are a popular to-go option for homeowners looking for affordable replacements for their damaged AC units. They come at cost-effective prices, and even though some may be slightly more costly, they’re worth all their extra features.

On the other hand, Lennox has slightly higher prices due to its many incorporated features.

AC Units

Goodman is one of the best air conditioning unit producers. The brand uses various universal components such as Copeland compressors. They also use Ultratech, the most well-known compressor in air and heating conditioning.

Although the quality components aren’t the best and the warranty might just suffer, the brand has improved massively over time. The overall ratings are very good.

Goodman’s parent company Daikin has lined up Goodman’s models to five air conditioners from 14 to 19 SEER. These models are stage one and stage two, giving you a performance choice.

The brand has included new features such as the ComfortBridge communication technology, which can be equipped into the split system’s furnace.

Communication technology makes use of algorithms for great performance and efficiency.

Lennox uses proprietary parts (parts designed for that particular unit) which slightly puts them at a disadvantage.

The parts are hard to get and if ever your HVAC unit has problems you might wait for some time before it gets to you, which is inconvenient to any customer.

These factors are best considered, but they don’t set the brands apart in a big way. Certain aspects can be worked around, so it’s about deciding what will work best for you.

What Lennox Does Better Than Goodman in Air Conditioning

Next up, let’s see where Lennox has the advantage and why many consumers prefer its products.


Efficiency is considered one of HVAC’s most essential features. This shows a unit’s ability to last in the long run, their convenience, and the occurrence of minimal losses long term. 

If any HVAC product is used daily, it should be able to last the minimum warranty term without costing much in repairs. Well taken care of units even last longer than expected.

Compared to Goodman products, Lennox products have the most advantages due to their units having the highest Seasonal Energy Efficiency Ratio (SEER) ratings in the market. With high-efficiency ratings, Lennox products are worth the investment because they can save on utility costs.

High Quality

Lennox produces superior models with meticulous performance and high quality. The company boasts about providing only the best for its customers and offering exclusive benefits.

The Lennox brand has industry-leading (up to 26) SEER ratings and SunSource units that are built to harness solar power.

Even on the hottest days, Lennox air conditioners have Precise Comfort technology that gives you full control of temperature in your workspace or home. When you purchase from the Lennox Signature collection, you gain access to a system that can modify your AC’s cooling ability to suit your local climate. 

Through the use of Silent Comfort technology, Lennox products are among the quietest, making them well built for efficiency.

Lennox also offers services like the following:

  • Installation services

  • Upgrading or replacing systems

  • Affordable repairs

  • Long-term warranties for long-term investments

  • Year-round maintenance plans

Goodman: 90%+ AFUE Furnaces

The best gas furnaces come in compact sizes, making them easy to store when not needed. You hardly think about them and pull them out only in winter. They run through quietly and perform effectively to your needs for years to come.

The majority of Goodman gas furnaces are designed to be energy efficient and have more to offer for their customers’ convenience:

  • They are designed from aluminum steel to withstand heat and wear over the years.
  • They have a multi PSC blower instead of a single-speed monitor. This reduces energy consumption and lowers noise production.
  • Available slope heat exchange design for optimal drainage.

Lennox: SLP98V

Lennox has furnaces that run on gas oil and with the two two furnace types, different features are offered to fit different customer needs.

The different models offer stage two furnaces, variable speed, and ultra-low emission. 

The SPL98V is Lennox’s number one flagship product. It has an industry-leading AFUE rating of 98.7 percent and was amongst the Energy-star certified products in 2019.

The unit:

  • Produces almost no noise.

  • It has two heat exchanges as well as condensing technology providing highly effective heat disbursement.

  • Has increased reliability and durability with its silicon nitride ignitor.

  • The systems work well with Lennox smart thermostat and run on natural gas

  • Venting options that are expanded unlike most base model units

  • Sealed blower compartment

  • Power-saving motor that helps reduce utility bills

  • An AFUE that is 96% and is Energy Star qualified.

Both budget model brands offer a great solution to consumers seeking low-budget units.

There are differences in both the brands such as Energy Star ratings.

Goodman: GSX13

The GSX13 provides efficient cooling with a SEER rating of 13. The unit is best for budget-conscious consumers as it’s affordable and still equipped with great features. Despite the low budget, it’s a well sought out choice by most consumers. The product is a single-stage and isn’t Energy Star rated.

Lennox: Lennox Merit ML296V

Due to its variable-speed blower and two-stage operation, the Lennox ML296V is the go-to choice for most consumers.

The Lennox Merit ML296V features are:

  • An AFUE of 96% and is Energy Star rated
