Why You Should Consider Buying the Lennox SL280NV Gas Furnace

Posted: 2020-12-29

The Environmental Protection Agency (EPA) is constantly updating its guidelines concerning “low NOx” equipment installed in residences. In some cases, contractors and distributors are not authorized to sell standard furnaces to consumers in certain areas.

NOx is the shortened form of nitrogen oxides, a category of reactive and toxic greenhouse gases. These gases are released when fuel is burned at high heat like in the heat exchanger of a furnace. NOx have significant impacts on the environment, and for this reason, the EPA had adjusted some of its regulations. The agency states that nitrogen oxides are the “chief causes of concern” because of their environmental effects, such as low water quality, toxic chemicals, ground-level ozone, acid rain, and global warming.

Features of the Lennox SL280NV Gas Furnace

This furnace is dubbed as “First-in-class, lowest emissions gas furnace”. It’s efficient and environmentally friendly, the SL280NV with our revolutionary design produces 65% lower NOx emissions than standard low-NOx furnaces. So you can feel good about your environment, inside and out.

This furnace comes with a 20-Year limited warranty on the heat exchanger. 10-year limited warranty on all remaining covered components.

Its low fan speed option efficiently controls humidity levels and provides continuous filtration for cleaner, healthier air.

Its durable steel cabinet is sleekly styled and made to last with a contoured design and high-quality paint finish.


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 SL280NV 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 SL280NV’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 SL280NV 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 SL280NV has a durable steel cabinet that is elegantly-styled with a 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.

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 SL280NV’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 SL280NV 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.
