Trane VS. Lennox ‑ Which AC Brand Is Better?

AC Unit

In South Florida, central air conditioning isn't a luxury — it's a necessity. Miami, FL routinely sees temperatures around 90 degrees and tops that off with plenty of humidity. A cool oasis at home is a must to make Miami life comfortable. Installing an HVAC system isn't as expensive as it used to be, particularly since many homes already have the needed infrastructure to support central cooling. With ductwork running throughout a home, the unit is the major price point.

So, how do you choose the right unit to cool your home? Take a look at some of the most used brands in the cooling business and find one that meets your budget without sacrificing on quality.

Trane and Lennox are two of the most commonly installed central cooling unit manufacturers in the United States. Both meet a very high standard for quality and have a lot to recommend them. You really can't go wrong with either of these premium brands, but there are some distinctions that may help you make a decision. Keep reading to get an idea of the differences in:

Comparing Trane vs. Lennox units, the prices are fairly comparable when looking at similar tiered options.

Trane single-stage units start at about $5,400, though that doesn't include installation costs. More efficient two-stage units from the same company start at $8,400.

Lennox doesn't offer pricing information directly to consumers since professional installation is required. However, many sites list the price range for the units at approximately $3,500-$5,500 for their most affordable options.

It's important to note that these are only the starting prices for the most basic style of unit. If you have a larger home or need higher energy efficiency, the cost of the unit goes up. It's not uncommon to pay more than $10,000 for a unit to cool a larger, single-family home in Miami.

If you want to update your AC and aren't sure about the expense, contact our team at Freezing Mechanical to talk about 13 SEER units that may be available at a discounted price. New regulations mean that all air conditioning installations in 2023 and on will need to have at least a 15 SEER rating here in South Florida, so it might be a good time to make the leap.


In the Trane vs. Lennox comparison, Trane is the clear industry leader. It beats out every other brand when it comes to quality.

The spine fin coil design is unique and plays an important role in the brand's ability to deliver consistent cooling over the long haul. In general, a Trane unit can be expected to last much longer than the 10-15 years that apply to most other units.

While Trane beats out Lennox for durability, that doesn't mean Lennox units aren't solidly built. Like Trane, Lennox uses an all-aluminum coil for a corrosion-resistant build. It also has premium tier units that are comparable to the best that Trane has to offer.

Where Lennox drops off in quality is in their mid- and lower-tier lines, the quality drop is accompanied by a price drop. Like in many industries, you often get what you pay for.

Energy Efficiency

In a head-to-head comparison of Trane vs. Lennox, Lennox wins in the energy efficiency category. Lennox units come in a range of SEER ratings from 13-28. That 13 SEER rating is being retired to comply with new minimum standards, but a rating of 28 is the best the industry has to offer. Lennox is the best at providing energy-efficient solutions for cooling.

By comparison, Trane produces air conditioning units with a SEER range of 14.5-22. While their lowest tier option is more highly rated than the lowest offering from Lennox, Trane can't compare when it comes to high efficiency.


When looking at maintenance, the cost of parts is the biggest hurdle when it comes to determining the cost of owning one of these air conditioning units. When parts are readily accessible and inexpensive, it makes it easier and more affordable to keep up with maintenance on your air conditioning unit. Unfortunately, parts accessibility and supply chain problems have been a consistent issue for Lennox, making the brand's units more expensive to keep in good repair. Lennox also uses the highest proportion of proprietary parts, so when something breaks, if we don't have the part in stock, you might have to wait while we order a replacement.

Trane also has some proprietary parts installed in its units — the spine fin coil, for example — but it also has plenty of standardized parts making it easier for repair technicians to get things up and running. Plus, Trane has a history of reliable delivery for parts that must be ordered directly from the company.


Trane offers one of the best warranties in the business for its premium line of HVAC units. With 10 years of coverage for parts and 12 years on the compressor, top-tier Trane air conditioners have the most comprehensive coverage. In fact, 10 years on parts and compressor is standard for all Trane units unless they offer an extended run. On the downside, to get these long and robust warranties, you must register your purchase within 60 days and all maintenance must be performed by a factory-authorized repair company.

With Lennox, their top-tier units come with the same 10-year warranty on compressors and parts, but their mid and lower-tier options may only have 5 years of coverage. The Merit line comes with only 5 years on both the compressor and other parts, while the Elite line offers 10 years on the compressor but only 5 years on any other parts.
