Breathe Better, Live Warmer: Why the Lennox SL297NV Furnace Is the Clean Comfort Upgrade Your Home Needs

, , , , ,

In Minnesota, heating isn’t optional—it’s essential. But comfort in your home isn’t just about staying warm. It’s about breathing clean, healthy air while maintaining a cozy, energy-efficient environment. If your current furnace is loud, inconsistent, or simply outdated, it might be time for a system that does more than just heat your space.

Enter the Lennox SL297NV Variable-Speed Gas Furnace—a next-generation heating system designed to deliver not only superior warmth but also exceptional air quality, energy efficiency, and quiet operation. At Marsh Heating & Air Conditioning, we believe your HVAC system should work harder so you don’t have to—and this model is proof.

Let’s take a closer look at why the SL297NV isn’t just a furnace—it’s an air quality solution for comfort-conscious homeowners.

Meet the SL297NV: Silent, Efficient, and Exceptionally Clean

The Lennox SL297NV is part of the Lennox Signature® Collection, a line known for best-in-class performance and smart energy use. What sets this model apart is its SilentComfort™ technology and its compatibility with Lennox’s Healthy Climate® air filtration systems.

That means while it’s keeping your family warm through subzero temperatures, it’s also working quietly and effectively behind the scenes to improve the air you breathe.

💨 Quiet Operation That Won’t Disrupt Your Life

Tired of the constant hum, clank, or roar when your furnace kicks on? The SL297NV uses variable-speed airflow and sound-absorbing insulation to minimize operating noise. The result? One of the quietest furnaces in its class.

The system doesn’t blast on and off like older models. Instead, it ramps up and down slowly, delivering consistent, gentle heat and maintaining a more even temperature throughout your home—all while keeping your peace and quiet intact.

🌬️ Cleaner Indoor Air with Every Cycle

What truly sets the SL297NV apart is its ability to improve indoor air quality. It’s the first furnace from Lennox to feature their innovative “SureLight®” ignitor and compatibility with the PureAir™ air purification system.

This means:

  • Less dust and airborne particles floating through your vents

  • Reduced allergens and airborne pollutants

  • Cleaner, healthier breathing environment for families with asthma or allergies

When paired with a Lennox air purifier or advanced MERV-rated filters, the SL297NV becomes more than a heating system—it becomes the foundation of a healthier home.

🔥 High-Efficiency Comfort with Up to 97.5% AFUE

The SL297NV boasts an impressive AFUE (Annual Fuel Utilization Efficiency) rating of up to 97.5%, meaning nearly every dollar you spend on energy goes directly into heating your home.

Here’s what that means for you:

  • Lower utility bills compared to standard furnaces

  • Less energy wasted through the flue or ductwork

  • Long-term savings that add up quickly

This furnace is ENERGY STAR® qualified, making it an excellent choice for eco-conscious homeowners or anyone looking to reduce household operating costs over time.

🚀 Smart Integration with iComfort® Thermostats

The SL297NV seamlessly integrates with Lennox’s iComfort® smart thermostats, giving you app-based control over your home’s heating system—even when you’re not there.

With features like:

  • Remote access

  • Programmable schedules

  • Weather-responsive automation

  • Maintenance alerts and system diagnostics

…you’ll never be left guessing if your system is running efficiently. It puts complete climate control at your fingertips.

Perfect for Minnesota Winters—and the Families Who Brave Them

For Minnesota homeowners, staying warm is more than comfort—it’s a safety issue. The SL297NV is built for extreme conditions, with durable construction and precision temperature control that delivers comfort even during polar vortexes and subzero nights.

But beyond the performance specs, this furnace stands out because it cares for your indoor environment holistically—reducing allergens, lowering noise, and ensuring consistent warmth from room to room.

Top Reasons Your Heating Bill Is So High—And What You Can Do About It

, , , , , , ,

If your energy bill seems to skyrocket every winter, you’re not alone. For homeowners in Minnesota, staying warm during long stretches of subzero temperatures is essential—but it doesn’t have to come at a steep cost. Often, the causes of high heating bills are avoidable or easily fixable. A few strategic changes can significantly reduce your energy use while keeping your home warm and comfortable.

Here’s a breakdown of the most common reasons your heating bill may be higher than it should be—and what you can do about it.

🔍 Why Your Heating Bill Might Be Too High

1. An Outdated Furnace

If your furnace is over 15 years old, it’s likely operating at 70–80% efficiency, even with regular maintenance. That means for every dollar you spend on energy, 20–30 cents may be going to waste.

Older models lack the modern features that newer systems have—like variable speed blowers or modulating heat—which help regulate comfort without constantly running at full power.

Solution: Consider upgrading to a high-efficiency model like the Lennox SLP99V, which boasts up to 99% AFUE (Annual Fuel Utilization Efficiency)—one of the most efficient furnaces available today.

2. Poor Home Insulation

Even the best furnace can’t do its job if your home is leaking heat. Drafty windows, gaps under doors, and poorly insulated attics or basements let warm air escape and cold air seep in. As a result, your heating system has to work harder and longer to maintain your desired temperature.

Solution:

  • Seal gaps with weatherstripping or caulk.

  • Insulate attic spaces, rim joists, and crawlspaces.

  • Use thermal curtains or window film in older homes to retain heat.

Not only will this help reduce your heating costs, but it also improves overall home comfort.

3. Dirty or Clogged Air Filters

A dirty air filter can restrict airflow throughout your home, causing your system to run longer and work harder to distribute warm air. In fact, this one simple issue can increase your heating costs by 10–15% and contribute to uneven temperatures in your home.

Solution: Replace or clean your furnace filter every 1–3 months, depending on usage and household factors like pets or allergies. It’s a low-cost habit that pays off in both efficiency and indoor air quality.

4. Inefficient Thermostat Use

Many households set their thermostats too high—or leave them running when no one is home. Heating an empty house wastes energy and money, and frequently adjusting the thermostat manually can lead to inefficient cycles.

Solution: Install a smart thermostat, such as the Lennox iComfort® model. These devices learn your patterns and automatically adjust temperature settings based on your daily routine and weather conditions. Some models even use geofencing to reduce heating when you’re away and increase it just before you return.

💡 Smart Ways to Lower Your Heating Bill

🔧 Schedule Regular Maintenance

Routine furnace maintenance ensures your system runs as efficiently as possible. Technicians can identify worn parts, calibrate settings, and clean components that affect performance. A well-maintained system uses less energy, lasts longer, and delivers more consistent heat.

🏠 Seal and Insulate Key Areas

Draft-proofing your home doesn’t require major renovations. Start small with:

  • Door sweeps

  • Window film

  • Foam gaskets for outlets on exterior walls

  • Insulating your attic and exposed ductwork

These improvements may qualify for utility rebates or energy incentives, saving you even more.

🔄 Upgrade Your Heating Equipment

A modern high-efficiency furnace like the Lennox SLP99V offers:

  • Variable-capacity heating

  • SilentComfort™ technology for whisper-quiet operation

  • Smart integration with iComfort® thermostats

  • Outstanding efficiency that helps reduce heating costs year after year

While upgrading is an investment, the long-term savings on energy bills—and the increased home value—make it worthwhile.

📱 Install a Smart Thermostat

Beyond convenience, smart thermostats help automate energy savings. Features like:

  • Remote access from your phone

  • Learning schedules

  • Energy usage reports

…make it easier to monitor and control heating costs in real-time.

Heat Pumps vs. Traditional HVAC Systems: Which Is Right for You?

, , , ,

When it comes to heating and cooling your home, choosing the right system can have a big impact on your comfort, energy efficiency, and utility costs. Heat pumps and traditional HVAC systems each have their own advantages, and the best choice depends on your climate, budget, and specific needs. Since Minnesota experiences bitterly cold winters, selecting the most effective heating system is crucial. Here’s a comparison to help you decide which system is right for you.

How They Work

  • Heat Pumps: Transfer heat rather than generating it. They extract heat from the air or ground and move it inside during the winter and outside during the summer.
  • Traditional HVAC Systems: Typically consist of a furnace for heating and an air conditioner for cooling. Furnaces generate heat by burning fuel, while AC units remove heat from indoor air.

Energy Efficiency

  • Heat Pumps: More energy-efficient in moderate climates, but in extreme cold temperatures, their efficiency drops, requiring supplemental heating.
  • Traditional HVAC Systems: Furnaces, especially high-efficiency gas models, provide consistent and reliable heat even during Minnesota’s harsh winters.

Climate Considerations

  • Heat Pumps: Best suited for milder climates, though cold-climate models have improved, they may still struggle in subzero temperatures without backup heating.
  • Traditional HVAC Systems: The best option for extreme cold climates like Minnesota, where a powerful furnace ensures dependable heat throughout winter.

Installation and Upfront Costs

  • Heat Pumps: Generally have a higher initial cost but offer lower operating expenses over time in moderate climates. However, in extremely cold regions, supplemental heating costs may negate those savings.
  • Traditional HVAC Systems: Furnaces and air conditioners have a lower upfront cost and are the more practical choice for Minnesota’s long, frigid winters.

Lifespan and Maintenance

  • Heat Pumps: Typically last around 15 years with proper maintenance. Since they run year-round for both heating and cooling, they may require more frequent servicing.
  • Traditional HVAC Systems: Furnaces can last 20 years or more, while air conditioners usually last around 15 years. Given the extreme winters in Minnesota, a reliable furnace is a long-term investment.

Environmental Impact

  • Heat Pumps: More eco-friendly as they don’t rely on burning fossil fuels and can be powered by renewable energy sources, but in extremely cold weather, they may need supplemental electric or gas heating.
  • Traditional HVAC Systems: Gas furnaces produce emissions but are a necessity in extremely cold regions where heat pumps may not perform efficiently.

Comfort and Performance

  • Heat Pumps: Provide even and consistent heating in moderate temperatures, but may struggle in extreme cold.
  • Traditional HVAC Systems: Furnaces generate powerful, high-temperature heat, which is essential for Minnesota’s freezing winters.

Financial Incentives

  • Heat Pumps: Qualify for various rebates and tax incentives due to their energy efficiency, though their savings in extremely cold climates may be limited.
  • Traditional HVAC Systems: May qualify for some rebates, and the cost savings of a furnace in extreme winters often outweigh the benefits of a heat pump.

Which System Is Right for You?

For Minnesota homeowners, a traditional furnace and air conditioner system is generally the best choice due to the state’s harsh winter conditions. While heat pumps can be efficient in milder climates, they may struggle to provide sufficient warmth when temperatures drop well below freezing. If energy efficiency is a priority, hybrid systems that combine a heat pump with a furnace can offer a good balance.

Experience Quiet, Efficient Comfort with the Lennox SL280V Variable-Speed Gas Furnace

, , , , ,

If you’re a Minnesota homeowner, you know that reliable heat isn’t a luxury—it’s a necessity. When winter temperatures drop below freezing, your furnace becomes one of the most important systems in your home. Choosing the right furnace can mean the difference between consistent comfort and frustrating cold spots—not to mention savings on your monthly energy bills.

At Marsh Heating & Air Conditioning, we’re proud to recommend the Lennox SL280V Variable-Speed Gas Furnace, a perfect blend of comfort, efficiency, and quiet performance. If you’re thinking about replacing your current furnace, here’s why the SL280V deserves a spot at the top of your list.

What Is the Lennox SL280V?

The Lennox SL280V is a variable-speed gas furnace designed to deliver consistent, energy-efficient heating throughout your home. It’s part of the Lennox Signature® Collection, which means it represents the very best in engineering, performance, and innovation.

What sets the SL280V apart is its two-stage heating and variable-speed blower motor, which allow it to operate at lower capacities for longer periods. This results in more even temperatures, quieter operation, and lower energy usage compared to single-stage or standard furnaces.

Key Benefits of the Lennox SL280V Furnace

✅ Two-Stage Heating for Improved Comfort

The SL280V can operate in two stages: low and high. During milder days, it runs in its lower stage, using less fuel and distributing heat more gradually. On colder days, it switches to the higher stage for full power when you need it most.

This flexibility means more even temperatures throughout your home and fewer temperature swings between cycles.

✅ Variable-Speed Blower for Energy Savings

The variable-speed motor is one of the most energy-efficient features of this furnace. Unlike standard blowers that turn on at full speed, the SL280V’s motor slowly ramps up and down, using only the power needed to maintain your desired temperature.

This not only saves electricity but also enhances humidity control in the winter and improves air circulation year-round.

✅ Ultra-Quiet Operation

Tired of the loud whoosh every time your furnace kicks on? The SL280V is designed with SilentComfort™ technology, which uses sound-absorbing materials and smooth startup features to keep noise to a minimum. It’s one of the quietest furnaces in its class—perfect for bedrooms or homes where peace and quiet are a priority.

✅ Up to 80% AFUE Efficiency

With an AFUE rating of up to 80%, this furnace converts 80 cents of every dollar spent on fuel into usable heat. While not as high as some 90+ AFUE models, it’s still a solid upgrade for homeowners replacing older systems with AFUE ratings in the 60–70% range.

This makes the SL280V ideal for homeowners who want to improve efficiency without switching to a high-efficiency condensing furnace.

✅ Seamless Integration with Lennox Comfort Systems

The SL280V is designed to work in perfect harmony with other Lennox components, including iComfort® smart thermostats, air purifiers, and humidifiers. When used as part of a complete Lennox home comfort system, you’ll enjoy a fully integrated solution that maximizes comfort, efficiency, and air quality.

Who Is This Furnace Best For?

The Lennox SL280V is a great option for:

  • Homeowners looking for better comfort and efficiency without the higher upfront cost of a 90+ AFUE furnace

  • People sensitive to noise, such as families with small children or those working from home

  • Anyone upgrading from an older, single-stage furnace that runs inconsistently or unevenly

  • Those who want a longer-lasting, more reliable furnace backed by a trusted brand

✅ Compact Design

Worried about space? The GWB9-IH is designed with a compact footprint, making it ideal for homes with limited mechanical room space or smaller basements. Despite its size, it doesn’t compromise on performance.
