Why it Stands Out to Us

This wonderful unit is perhaps one of the best-designed gas furnaces in the market. Be it the user convenience or the quality of performance; it covers both grounds well. One of the most outstanding parts of this unit is its warranty service. 

The brand will replace the entire unit in case it fails in the first 10-years of its usage. Furthermore, there is another 10-year limited part warranty as well. 

In conjunction with the warranty, it also has an intelligent and convenient design. It has an Ion system control for intelligent and convenient diagnostics, which is remote controlled and Wi-Fi enabled. 

Bottom Line

All in all, this unit is a beauty. It is incredibly innovative and well-engineered. The design is new and equipped with technology to make usage, diagnostic, and performance better. Thus, it’s a great investment.

Why it Stands Out to Us

This highly innovative and intelligently designed gas furnace caught our attention with its impeccable design that caters to the comfort and convenience of the consumer. It features a two-stage gas valve operation which is reliable as well as energy-efficient.  

However, its most attractive feature is its quiet operation, which is made possible due to the noise-reducing features in it.

It also has a dual-fuel capacity with a compatible thermostat and heat pump. These further add to the energy efficiency of the model. Furthermore, it even has a 5-year hassle-free return warranty and a 1-year limited part warranty, making the unit an even more fruitful purchase. 

Bottom Line

Overall, this unit is very deserving of the runner-up position. It is incredibly well-designed and carries multiple features that promote a comfortable yet energy-efficient experience. It carries a superb warranty and high-quality construction as well.

Unit Warranty: Lifetime Heat Exchanger Limited Warranty

Why it Stands Out to Us

The G80CSU is a stunning gas furnace that is well-engineered and provides superior performance as well, which is precisely the reason why it caught our attention. 

The stand out feature of this unit is the reduced NOx emissions. Many states and places like California have a strict policy regarding air quality management, where this unit could be the perfect fit. NOx contributes to smog and acid rain, which is why this unit proves to be environment-friendly. 

Furthermore, it has a single valve and quiet operation due to the noise-reducing features. It even features variable speed and constant airflow ECM motor for superior temperature control. 

Bottom Line

In all, this incredible unit provides a great bang for the buck with its stunning design and superior performance. It is environment-friendly as well without reducing the comfort or convenience levels for consumers.
