Lennox’s Merit 16ACX is an entry-level offering from the brand, but it’s the most sophisticated of their standard air conditioners.
One of the things that sets the Merit 16ACX apart from the brand’s other entry-level systems is its two-stage compressor, which translates to quieter operation, a higher efficiency rating, and better humidity control throughout the summer.
The Merit 16ACX is a great option for homeowners who want a more affordable air conditioner from a premium brand, and that provides a good balance between luxury and value.

The Bottom Line
The Merit 16ACX is a more affordable entry-level air conditioner with a more sophisticated two-stage compressor. This means it can operate on a lower speed for longer periods for more efficient and quieter performance while also delivering more even temperatures throughout the house.
Plus, it offers improved humidity control compared to single-stage compressors. Furthermore, when the model is paired with a variable-stage furnace, it delivers even better humidity control.
There are a few sub-models of the Merit 16ACX that have SEER ratings ranging from 14 to 17, so if energy performance is one of your main concerns, then pay attention to the efficiency rating of the specific sub-model you're looking at.
The Merit 16ACX has been designed to last and has many features that increase durability, but it’s also backed by a good warranty in case anything does go wrong.
In Depth Review
Lennox Merit 16ACX Product Specifications
- Compressor: Two-stage
- SEER: Up to 17
- ENERGY STAR certified: Yes
- Decibel rating: As low as 75
One of the great things about Lennox air conditioners like the Merit 16ACX is that they’ve been built to last. For example, they have things like special cabinet designs that are made to withstand years of being out in the elements.
The Merit 16ACX has also been designed with peace and quiet in mind, and along with the quieter two-stage compressor, it also has special fan and blade features that reduce noise while improving efficiency and air circulation.
Finally, this and other Lennox air conditioners have been designed for easy installation, and that means you could save on labour costs when you first buy the unit.
Other Key Features
- Direct-drive fan that’s both quiet and energy efficient
- Fan motor and blades that increase air circulation
- Special PermaGuard cabinet that’s rust- and corrosion-resistant for lasting performance
- Durable cabinet materials that will last through many summers
- Safe and easy to install
Like the other models in Lennox’s Merit line, the 16ACX is backed by a five-year limited warranty that covers parts and the compressor.
However, you can extend the warranty to 10 years if you register the unit online through Lennox. You typically have between 60 and 90 days to register a newly installed unit to take advantage of the extended registered warranty terms.
To register, you'll need things like the unit’s serial number, installation date, and the name and address of the professional dealer who did the installation.
Comparable Models by Lennox
Model Comparison by Price: Lennox Merit 16ACX versus Dave Lennox Signature Collection XC25
The XC25 is the most expensive model from Lennox because it’s their top-of-the-line unit. It’s a premium unit with a SEER rating of 26, so it falls into the $7,000 to $9,500+ range. Although this model is quite a bit more expensive, it does have more perks than the Merit 16ACX.
For example, the XC25 has a variable-speed compressor that can make incremental adjustments for even better performance, and that includes quieter operation, improved efficiency, better humidity control, and more even temperatures. Plus, this model comes equipped with all of Lennox’s additional features, including the SilentComfort and Precise Comfort technologies.
It should be noted, however, that while this air conditioner is extremely advanced, the 26 SEER rating is much higher than what we typically need for our milder Canadian summers, and the money you save on energy bills won’t necessarily justify the additional cost of the unit.
Model Comparison by Features: Lennox Merit 16ACX versus Lennox Elite XC20
The Elite XC20 is a model from Lennox’s mid-range air conditioner series. It has a SEER rating of 20, and the efficiency rating and tier put it in the same price category as the XC25, though the XC20 will be more affordable than the top-of-the-line model.
The XC20 also has a more advanced variable-speed compressor than the Merit 16ACX, so it’s quieter, more efficient, and promises steadier temperatures. It was also designated as one of the ENERGY STAR Most Efficient 2021, so there might be additional rebates it qualifies for.
Another feature that the XC20 offers is a longer warranty than the Merit 16ACX: the XC20 automatically comes with a 10-year warranty for the compressor, and the five-year parts warranty can be extended to 10 upon registration.
Finally, the XC20 has a decibel rating as low as 65, so it’s also quieter than the Merit 16ACX.
Model Comparison by Tier: Lennox Merit 16ACX versus Lennox Merit 13ACX
The Merit 13ACX is in the same tier as the Merit 16ACX, but it’s a much simpler and more basic air conditioner. For one thing, the 13ACX has a SEER rating of 13, which means it can’t qualify for ENERGY STAR certification. It also has a less efficient and noisier single-stage compressor.
At the same time, the Merit 13ACX has all the same durability features as the Merit 16ACX, has been rigorously tested for reliable and long-term performance, and comes with the same standard and registered warranty terms.
Another thing about the Merit 13ACX is that it falls into the $3,500 to $5,000 price range, so it’s cheaper than the Merit 16ACX.
