A Spotlight on the Lennox SL280V Two-Stage Gas Furnace

Posted: 2019-11-19

Do you notice a steady rise in your heating bills? Has your old furnace been in need of continual repairs? If so, you may need to consider investing in a new heating system. That’s because older furnaces tend to lose their efficiency as they become old. If your furnace reaches this point, not only is it inconvenient, it is also impractical since you are wasting energy and money at the same time.

Here at Four Seasons Air Specialists, we take your home comfort very seriously. We want you to have the best comfort while keeping your home energy-efficient. That is why we partnered with Lennox to provide you with some of the best high-efficiency furnaces available on the market today. We are your trusted heating company in Grant MN.

Features of the Lennox SL280V Two-Stage Gas Furnace


A variable-speed furnace does not tend to overwork because it can control its operation to match your heating needs. Since your fan isn’t set at maximum all the time, it uses less power, which results in lower energy bills.

Its dual-fuel capability can be merged with an electric heat pump to create a dual-fuel system that maximizes comfort and fuel efficiency by seamlessly alternating between electric and gas heat, optimizing energy use and minimizing heating costs.

The SL280V has an efficiency rating of up to 80 percent AFUE, which can save you hundreds of dollars in heating costs per year, compared to older, low-efficiency furnaces.

When installed with the user-friendly programmable iComfort Wi-Fi thermostat, the SL280V’s iComfort technology will enable the furnace to swap information and make accurate adjustments to optimize performance and fuel efficiency.

To minimize heat loss and maximize comfort and efficiency, Lennox created a sealed blower compartment for this model.

When matched with a Lennox air conditioner or heat pump, the SL280V can enhance your cooling Seasonal Energy Efficiency Ratio (SEER), which leads to greater energy-efficiency and lower energy costs.

To further decrease heat loss, the SL280V has a durable steel cabinet that is elegantly-styled with high-quality paint finish.

Temperature Control

A variable-speed furnace can maintain indoor air temperature with an accuracy that traditional single-speed furnaces can’t match. A conventional furnace pushes a predefined amount of hot air into a room until a certain temperature is met. Then, it shuts off until the temperature decreases again while a variable-speed furnace is able to effectively circulate enough heated air into a space to keep a specific temperature.

The SL280V has a Duralok Plus heat exchanger, which is constructed from patented ArmorTuf steel that captures waste heat, and a stainless steel secondary heat exchanger that allows the unit to achieve industry-leading efficiency levels. This solid component exceeds industry requirements and extends the furnace’s life.

Its variable-speed motor provides a quiet and consistent flow of air for an ideal balance of temperature and humidity throughout your home, giving your home enhanced comfort.

The SL280V’s ultra-low continuous fan speed provides a quiet, constant flow of air and optimizes indoor air quality devices.

Operational Sound

Operating your fan at a slower speed when the top speed isn’t necessary means a much quiet overall performance. You wouldn’t hear a constant loud noise that accompanies the blower going on when the temperature has dropped. One innovative benefit of variable-speed operation is that it continuously circulates air. This is also beneficial for you in terms of indoor air quality because the air passes through your furnace filter more often, removing more airborne contaminants.

The SL280V is regarded as the quietest furnace in its price range. With its SilentComfort™ technology that utilizes advanced engineering and special sound-absorbing materials, it is up to 4 times quieter than comparable models.
