A Spotlight on the Lennox SL280NV Gas Furnace

Posted: 2019-12-10

One may think that choosing the best furnace is all about the price — you’ll never go wrong with the most expensive unit. However, this is a myth. In fact, picking the right heating system is much more complicated than you might think.

Thankfully, you have your preferred heating company in Shoreview MN like Four Seasons Air Specialists to guide you through the process. Here are a few factors to consider:

Efficiency Rating

AFUE (Annual Fuel Utilization Efficiency) rating is one of the most important elements you need to look for. The general rule of thumb is that the higher the AFUE rating, the more efficient the furnace is. However, be mindful that high-efficiency furnaces cost much higher than low and mid ones. The U.S. government requires all manufacturers and dealers to sell furnaces with a minimum of 80 percent AFUE.

Proper Sizing

When it comes to heating systems, bigger is not always better. An oversized furnace tends to heat up the home too quickly, but is also prone to short cycling, which causes the system to fail to consistently provide your desired temperature. It also shortens the system’s lifespan.

On the other hand, an undersized furnace doesn’t have the heating capacity to evenly distribute heat in all rooms. As a result, the system is forced to work harder than normal, causing it to overheat. The main problems associated with furnaces that are too small include excessively high utility costs and abbreviated equipment lifespan.

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 a sleekly styled and made to last with a contoured design and high-quality paint finish.

Energy-Efficiency

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 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.
