Lennox SL280V

If you’re one of the many homeowners looking for a brand new furnace, you have come to the right place. Marsh Heating and Air Conditioning is a heating company in Champlin MN that is licensed by Lennox Industries to offer its full line of residential gas and oil furnaces.

A good combination of comfort and efficiency is what you should look for in a new heating system — and consider a unit that incorporates a variable-speed fan.


New furnace models have a lot of benefits to offer. However, having a variable-speed blower is one of the most functional.

If you have a low-efficiency furnace, its blower motor only works at one speed that is pre-programmed before the furnace is even installed. The air handler will operate constantly at a high speed even if your airflow needs are much different.

On the other hand, a variable-speed furnace works at different speeds and is able to match your home’s airflow requirements at any given time. The blower will always operate at the lowest possible speed and adjust to a higher setting only when more airflow is required.

How the Lennox SL280V Will Benefit You

Lower Energy Consumption

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.

Greater 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.

Quieter Operation

Operating your fan at a lower 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.
