Comparison between Lennox and Carrier, Air Conditioner Vs. Carrier: Which To Choose

Comparison of Lennox and Carrier Air Conditioners

Lennox and Carrier have been at the top of the air conditioning game for decades.

According to consumer research, both companies have consistently produced durable and reliable cooling units that rank high in efficiency, quality, and variety of features.

However, there are qualities in which one brand outshines the other. Knowing which brand pulls ahead in the particular factor that weighs the heaviest in your decision-making is important.

Let's explore the similarities and differences in several aspects between these two brands.

Energy efficiency

The basis for determining energy efficiency in different AC models usually comes down to their SEER rating.

SEER stands for seasonal energy efficiency ratio, which is the ratio of the cooling output for the entire cooling season to the electricity input.

Simply put, the higher the SEER rating of an AC unit, the less electrical energy it needs to operate. This is important when it comes to saving on electricity bills and having eco-friendly appliances in the house.

When it comes to energy efficiency, Lennox is ahead of the competition.

The company is extremely invested in this area, boasting the most energy-efficient AC model in the market: the Signature Series Lennox XC25 has a 26 SEER rating. Nine of their models are also Energy Star certified.

Carrier also has energy-efficient models in different price ranges. They have:

  • the Carrier Infinity 21 with a 21 SEER rating,
  • the Carrier Infinity 17 with a 17 SEER rating,
  • and the Carrier 24ABC6 with a 16 SEER rating.

Every air conditioner unit comes with a variety of features depending on whether you get a basic, mid-range, or top model. Here are some of the most important features that both Lennox and Carrier offer:

1. Humidity control

This feature removes humidity from warm air, making the home feel more comfortable in hot weather. The Infinity Touch model from Carrier and the Climate IQ technology from Lennox offer this feature.

2. WiFi

Lennox only offers WiFi function for its top models, while Carrier offers it for all models - even ones on the lower price range.

3. Smart thermostat

With this feature, you can track and control your HVAC system through an app on your phone or tablet. Carrier offers the Infinity and Côr thermostats, while Lennox offers the iComfort S30.

4. Compatibility

The AC system can also integrate with other smart automation systems and devices in the home, giving you easy access and control.

Carrier is compatible with both Côr™ Smart Home and Alexa while Lennox is only compatible with Alexa.

5. Communicating technology

This advanced feature allows different components in the HVAC to communicate, resulting in more balanced temperatures, more energy conservation, easier maintenance,  and increased comfort at home. While Carrier was the first brand to offer this feature, Lennox's top models also have it.

6. Variable fan

Unlike one-stage or two-stage systems, a variable fan can operate at different levels and increase or decrease its speed based on your desired temperature. Both Lennox and Carrier have this.

As you can see, there are only slight differences in the features each brand has to offer. Carrier does have the advantage in this aspect since it has more compatibility and offers WiFi function across all models.

Both brands have models with three types of compressors that are responsible for how the AC system operates, namely:

  • Single-stage -  Gets activated when the indoor air reaches a higher temperature than that of your thermostat's setting. Runs solely at full capacity.
  • Double-stage - Runs at both full capacity and at 60-70% capacity with both high and low-speed settings; saving more energy than single-stage compressors.
  • Variable-stage - The most energy-efficient option. It can run at as low as 25-30% of its full capacity and has three or more speed settings.  Depending on your home's cooling needs, a variable-capacity unit can adjust its speed and capacity in small increments.

Lennox offers a wider range of compressor types for different budgets. Its most efficient variable-stage unit, Lennox XC25, has a capacity range of 35% to 100%. It also has 65 speeds, meaning it changes capacity in increments of 1%.

Compared to Lennox, Carrier has fewer options when it comes to compressor types. Its best variable-stage unit isn't quite as impressive as that of Lennox. It has a capacity range of 25% to 100% and five speeds, changing capacity in increments of 18.75%.

Like any other equipment, it's inevitable that your air conditioner will need repairs and maintenance. So convenience should definitely factor into your choice.

While it's popular for its energy-efficient models, Lennox also has a reputation for making units that are difficult to repair.

When your unit needs repairing, you'll have to find Lennox parts exclusively, or the job can't be completed. This means repairs take longer, and parts typically cost more.

On the other hand, you can find parts for Carrier unit repairs almost anywhere. They're also much cheaper, so you should have no trouble having them repaired.

With Carrier's Infinity® series and Lennox's Dave Lennox Signature® Collection, both brands offer state-of-the-art cooling systems with advanced technology.

However, Lennox has gained the upper hand with their Ultra Comfort System™ which has precision sensors to keep your home at the ideal temperature all throughout the day, in every area of the house.

Price & Warranty

It's tricky to compare costs for these brands since you won't be spending on the unit alone. You'll also have to factor in installation costs, and these vary according to different factors, such as your location.

On average, however, Lennox tends to be on the pricier side compared to Carrier. Its top models are around 10% to 20% more expensive than that of Carrier.

In addition, a unit from Carrier may cost around $1,400 to $4,700 to install, while a unit from Lennox can cost around $3,110 to $7,340.

Carrier also offers a longer warranty than Lennox. All Carrier models have a warranty of 10 years, while Lennox only offers 10-year warranties for units in the Signature Series. Units in the Elite and Merit series have a 5-year warranty.

This depends on your needs and budget range. Two of the highest-rated Carrier ACs according to experts and consumers are:

  • Carrier 24VNA (Infinity Series) - This Energy Star-certified model with a SEER rating of 19 is one of the most energy-efficient units on the market, equipped with five speeds and an ability to run at 25% to 100% capacity.
  • Carrier 24ANB7 (Infinity Series) - With two-stage compression, this model provides comfortable cooling when needed but can also operate when it's in low-stage.
