Energy Efficiency
It’s not an exaggeration to say that Lennox furnaces are the HVAC industry’s gold standard for energy efficiency. The brand is known for innovations that cut running costs, with its most premium furnaces approaching near-complete conversion of fuel into heat.
Looking at the Lennox SLP99V — the brand’s flagship furnace — the system offers an impressive 99% AFUE rating, which means only 1% of your fuel is wasted during operation. However, this alone isn’t the only reason why Lennox furnaces are so efficient. They also feature:
- Variable speed technology that adjusts heating output more precisely
- Advanced motors that minimize electricity consumption
- Dual-fuel capability to switch to a heat pump when it’s more efficient
The Carrier Infinity 98 furnace is the closest comparison to the Lennox SLP99V and offers a near-equivalent 98.5% AFUE rating.
However, many furnaces from Lennox’s mid-range Elite series offer 96% or 97% AFUE ratings. Although Carrier has some equivalent furnaces with 96% efficiency ratings, most of this brand’s mid-range furnaces feature 80% AFUE ratings. This means you get better efficiency with Lennox furnaces across most price points.
Innovative Features and Technology
Lennox and Carrier furnaces both gain innovative features all the time, so if you’re seeing signs you need to replace your furnace, remember that an upgrade brings higher efficiency and new technologies.
The most significant change a modern furnace brings is the ability to connect with smart home devices through Google or Alexa. Lennox offers this through its iComfort thermostats, unlocking features such as:
- Remote temperature changes via smartphone
- Maintenance alerts to cut the risk of breakdowns
- Real-time energy monitoring and automatic efficiency adjustments
- Weather-based optimizations based on local forecasts
Many Lennox furnaces feature Precise Comfort, which allows 1% temperature adjustments to maximize efficiency and create the ideal warmth for any space. Premium systems also feature SilentComfort, which uses noise-canceling shielding and an optimized fan ramping to cut sound by up to 50%.
Although Carrier has several similar features, Lennox offers more user-friendly smart integration, a slightly wider temperature adjustment capacity, and better energy-tracking capabilities. These qualities often make it the more approachable furnace brand for families.
Durability and Reliability Comparison
Furnaces with a long lifespan represent exceptional value for homeowners because the initial purchase cost goes further.
When comparing a Carrier vs. Lennox furnace, there are a few differences in longevity. Most importantly, Lennox goes above and beyond in the construction of its heat exchangers — a component that frequently fails in older furnaces. High durability is especially vital for heat exchangers, as they’re also one of the most expensive parts to repair or replace.
Both Lennox and Carrier offer a lifetime warranty on the heat exchanger but not the labor to install a replacement. You also get a 10-year limited warranty on other major components and can access extended warranty options for some forms of labor.
However, Lennox receives many positive reviews for its more comprehensive and responsive customer care, making the brand potentially easier to work with than Carrier if something goes wrong.
Why Choose Lennox for Your Home?
Furnaces can be expensive, so you want your chosen system to last many years and consume as little fuel as possible. With this in mind, Lennox is a clear winner, but the brand also edges ahead through innovative features, durability, and exceptional aftermarket care. Just make sure you get a reliable company to install your furnace for maximum performance.
