The Perfect Balance: Why the Lennox EL297V Furnace Is a Smart Choice for Reliable, Energy-Saving Comfort

, , , , ,

When it comes to Minnesota winters, there’s no room for unreliable heating. You need a furnace that works hard, runs efficiently, and keeps your home comfortable through every polar plunge. But that doesn’t mean you have to overspend on high-end features you’ll never use. If you’re looking for a smart, cost-effective solution that delivers consistent performance and real energy savings, the Lennox EL297V Variable-Speed Gas Furnace is worth your attention.

At Marsh Heating & Air Conditioning, we help homeowners find the right heating system for their comfort, budget, and long-term needs—and the EL297V hits the sweet spot.

What Makes the Lennox EL297V Different?

The EL297V is part of the Lennox Elite® Series, which blends advanced technology with affordability. It’s the ideal option for homeowners who want:

  • Quiet, even heating throughout the house

  • Strong energy efficiency

  • Better indoor air quality

  • Dependable performance without overcomplicating things

It’s a serious upgrade from standard furnaces—and a smart middle-tier option between entry-level models and top-of-the-line units.

🔁 Two-Stage Heating + Variable-Speed Fan = Customized Comfort

What sets the EL297V apart from basic furnaces is its two-stage gas valve and variable-speed blower motor.

  • Stage One: The furnace runs at a lower capacity during milder weather, maintaining a consistent temperature while using less energy.

  • Stage Two: When temperatures drop, the furnace ramps up to deliver full heat power, keeping your home warm and toasty.

This dual-stage operation offers two huge benefits: greater energy efficiency and more stable temperatures. No more rollercoaster heating cycles or hot/cold swings—just consistent, comfortable warmth.

And with a variable-speed fan, air circulates more evenly, improving comfort in every room while enhancing air filtration and humidity control.

💰 Energy Efficiency That Pays Off

The EL297V delivers up to 97% AFUE (Annual Fuel Utilization Efficiency), meaning 97 cents of every dollar you spend on heating goes directly into warming your home—not out the chimney.

Compared to older, single-stage furnaces with 70–80% AFUE ratings, that’s a big leap in efficiency—and a clear path to lower monthly heating bills.

Even better, the EL297V is ENERGY STAR® certified, so it may qualify for utility rebates or tax incentives depending on where you live.

🤫 Quiet Operation You’ll Appreciate

Thanks to Lennox’s SilentComfort™ technology, the EL297V operates with minimal noise—great for light sleepers, families with small children, or anyone who appreciates peace and quiet.

You won’t hear clanking, roaring, or abrupt starts. Instead, the variable-speed motor ensures smooth, quiet operation that fades into the background of your everyday life.

🌬️ Better Indoor Air, All Year Long

When paired with a high-efficiency Lennox air filter or the Healthy Climate® air purification system, the EL297V can also help improve your indoor air quality. The variable-speed motor runs longer at low speeds, giving your filter more time to capture:

  • Dust and pollen

  • Pet dander

  • Airborne bacteria and viruses

  • Mold spores and other allergens

This is especially beneficial during the winter months when your home is sealed tight and indoor air can become stale.

Perfect for Minnesota Winters—and Practical Homeowners

While some homeowners prefer top-of-the-line models with all the bells and whistles, others want smart performance at a smart price. That’s exactly where the EL297V shines.

Whether you’re upgrading an aging system, finishing a basement, or simply want to save money on heating costs without sacrificing performance, the EL297V offers reliable, efficient comfort—even when the temperature dips well below zero.

Let Marsh Heating & Air Conditioning Help You Install It Right

Choosing the right furnace is only part of the equation—proper installation and expert support are just as important. With over 50 years of experience serving homeowners across the Twin Cities, Marsh Heating & Air Conditioning is your trusted partner for:

  • Honest system recommendations

  • Precise installation by certified technicians

  • Maintenance plans and ongoing service support

  • Guidance on available rebates and incentives

📞 Call Marsh Heating & Air Conditioning today at 763.536.0667 or visit MarshHeating.com to schedule a free estimate and learn more about whether the Lennox EL297V is the right fit for your home.

Comfort, efficiency, and peace of mind—right when you need it most.

Flexible Comfort for Every Room: Where the Lennox Multi-Zone Mini-Split System Shines

, , ,

Not all homes are created equal when it comes to heating and cooling. Some rooms run hot while others stay stubbornly cold. Maybe you’ve added a new sunroom or finished your basement—but your existing HVAC system can’t quite reach it. Or perhaps you’re looking for a way to control the temperature in individual spaces without costly ductwork.

If this sounds familiar, you’re not alone—and you’re not out of options.

The Lennox Multi-Zone Mini-Split System offers a smart, efficient solution for heating and cooling those tricky spaces. With whisper-quiet operation, flexible installation, and zoned control, it’s one of the most versatile comfort systems available today.

At Marsh Heating & Air Conditioning, we recommend Lennox mini-split systems to homeowners looking for high-efficiency comfort in areas where traditional HVAC isn’t practical or cost-effective. Let’s explore what makes this system special—and where it works best.

What Is a Multi-Zone Mini-Split System?

A mini-split is a ductless heating and cooling system made up of two key parts:

  • An outdoor unit, which houses the compressor and condenser

  • One or more indoor air handlers, which distribute warm or cool air into individual rooms

What sets the Lennox Multi-Zone Mini-Split apart is its ability to connect multiple indoor units to a single outdoor unit—giving you independent control of temperatures in different rooms or zones.

Think of it as customized climate control for every corner of your home.

Where the Lennox Multi-Zone Mini-Split System Works Best

Mini-splits aren’t just for tiny homes or detached garages (though they’re great for those, too). They’re ideal for solving specific heating and cooling challenges that central HVAC systems can’t handle well.

🧩 Home Additions or Renovations

Adding a sunroom, finished basement, or garage conversion? Extending your existing ductwork can be expensive, inefficient, or even impossible.

A Lennox mini-split lets you heat and cool the new space independently—without overburdening your main system.

🏠 Older Homes Without Ductwork

Many older Minnesota homes were built before central heating and air became common. Running ductwork through thick walls or historic structures can be disruptive and costly.

Mini-splits provide modern comfort without gutting your home. The small, wall-mounted units blend into your décor and require only a small conduit hole.

🌡️ Rooms with Unique Heating/Cooling Needs

Some rooms just don’t match the rest of the house. Think:

  • Upstairs bedrooms that overheat in summer

  • Kitchens that get hot from cooking

  • Home offices that need quiet, controlled temperatures

With a multi-zone mini-split, you can adjust each room individually, keeping everyone happy without wasting energy.

🛏️ In-Law Suites or Guest Quarters

Have a multi-generational household? The Lennox mini-split system allows guests or family members to set their own comfort levels, whether it’s warm and cozy or cool and breezy.

Benefits of the Lennox Multi-Zone Mini-Split System

Lennox takes mini-split technology to the next level with premium features that make daily life easier and more energy efficient.

✅ Zoned Comfort

Control each indoor unit separately via remote or app. No more thermostat wars or heating unused spaces.

✅ High-Efficiency Operation

Mini-splits are already more efficient than baseboard heaters or window units—but Lennox’s inverter technology modulates power to reduce energy use even further.

✅ Quiet Performance

Indoor units run quietly, making them perfect for bedrooms, nurseries, or home offices. You’ll feel the comfort—not hear it.

✅ Sleek, Modern Design

The air handlers are compact and wall-mounted, with a clean, minimalist look that suits most interiors.

✅ Heating + Cooling

Lennox mini-splits work year-round—cooling in summer and heating in winter—making them a four-season solution.

Installed by the Experts at Marsh Heating & Air Conditioning

Installing a multi-zone mini-split system takes expert planning and precision. At Marsh Heating & Air Conditioning, we assess your space, recommend the ideal number of zones, and install your system for maximum efficiency and comfort.

Whether you’re dealing with uneven temperatures, building an addition, or simply want more control over your environment, the Lennox Multi-Zone Mini-Split System is a powerful and flexible option.

You deserve comfort in every room—without compromise. Let Lennox and Marsh make it happen.

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.

How the Lennox iComfort® Smart Thermostat Can Save You Money

, , , ,

Your thermostat may be small, but it plays a big role in your home’s comfort and energy consumption. As the control center of your HVAC system, it determines when and how often your furnace or air conditioner runs—and how much energy it uses in the process.

If you’re still relying on a manual or basic programmable thermostat, you could be missing out on significant energy savings. Upgrading to a Lennox iComfort® smart thermostat gives you advanced control over your indoor climate, helping you reduce waste, improve comfort, and cut down on utility bills—all from your phone or tablet.

At Marsh Heating & Air Conditioning, we install and support the full line of Lennox iComfort thermostats to help Minnesota homeowners take full control of their energy use, no matter the season.

✔ Smart Zoning

Some iComfort models allow for custom temperature zones throughout your home. This lets you reduce energy usage in unused areas while keeping occupied rooms comfortable—saving money without sacrificing comfort.

✔ Real-Time Weather Adaptation

iComfort thermostats use live weather data to adjust your system’s output. On a sunny but cold winter day, your system may use less energy to maintain the desired temperature, saving money automatically.

Top Lennox iComfort® Models to Consider

Easy Home Upgrades to Improve Energy Efficiency

, , , ,

Lowering your home’s energy bills doesn’t have to mean a full renovation or investing thousands of dollars. In fact, some of the most effective ways to boost your home’s energy efficiency are also the easiest—and many will pay for themselves in just a few months through reduced utility costs.

Whether you’re trying to make your home more sustainable, improve comfort, or simply save money, these simple upgrades can make a big difference. From smart technology to HVAC improvements, here are five easy ways to upgrade your home and enjoy better efficiency every season.

1. Upgrade to a Smart Thermostat

Your thermostat is the brain of your HVAC system—and upgrading to a smart thermostat is one of the quickest ways to reduce energy waste. Modern models, like the Lennox iComfort® smart thermostat, offer much more than basic temperature control.

Benefits of a Smart Thermostat:

✔ Control your home’s temperature remotely from your smartphone or tablet.
✔ Automatically adjusts based on your schedule, weather patterns, or when you leave the house.
✔ Offers real-time energy usage insights to help you make smarter choices.
✔ Reduces heating and cooling costs without sacrificing comfort.

With zoning capabilities and integration with voice assistants like Alexa or Google Assistant, smart thermostats make efficiency easy and convenient.

2. Replace Old Light Bulbs

Still using incandescent or CFL bulbs around the house? Upgrading to LED lighting is a small change that delivers big savings.

Why LEDs Make Sense:

✔ Use up to 75% less energy than traditional bulbs.
✔ Last up to 25 times longer, meaning fewer replacements and less waste.
✔ Available in multiple brightness levels and color temperatures for every room.
✔ Emit less heat, which helps keep rooms cooler in the summer.

Whether you’re swapping out bulbs one room at a time or upgrading your entire home, this is one of the most cost-effective energy efficiency improvements you can make.

3. Seal and Insulate Ductwork

Many homeowners don’t realize that leaky ductwork is one of the biggest sources of energy waste. In fact, the U.S. Department of Energy estimates that up to 30% of heated or cooled air is lost through holes, gaps, or poorly connected ducts.

Fixing Ductwork Can:

✔ Improve airflow throughout your home.
✔ Reduce the strain on your HVAC system.
✔ Help maintain consistent temperatures from room to room.
✔ Lower your monthly energy bills.

Professional duct sealing from a trusted provider like Marsh Heating & Air Conditioning ensures your HVAC system delivers air where it’s needed—without energy waste.

4. Install a Whole-Home Dehumidifier or Humidifier

Indoor humidity plays a major role in your comfort—and in your HVAC system’s performance. When humidity is too high or too low, your furnace or air conditioner has to work harder to compensate.

Benefits of Humidity Control:

✔ Dehumidifiers reduce sticky air and prevent mold growth in the summer.
✔ Humidifiers add moisture to dry winter air, reducing respiratory discomfort and protecting wood floors and furniture.
✔ Balanced humidity means you can run your system less often while staying comfortable.
✔ Helps protect your indoor air quality by reducing allergens and airborne irritants.

At Marsh Heating & Air Conditioning, we offer whole-home humidity solutions that integrate with your existing HVAC system for precise, energy-saving results.

5. Schedule a Home Energy Audit

Sometimes, the best upgrade you can make is knowledge. A home energy audit evaluates how your home uses energy and pinpoints areas of loss or inefficiency.

A Professional Audit Can Reveal:

✔ Areas with poor insulation or drafts
✔ HVAC performance issues or inefficiencies
✔ Opportunities to upgrade appliances or systems
✔ Tips to improve air quality and comfort

Marsh Heating & Air Conditioning can conduct a thorough HVAC inspection as part of your energy audit, identifying inefficiencies like dirty coils, leaky ducts, or aging components that affect both performance and costs.

Take the Next Step Toward a More Efficient Home

At Marsh Heating & Air Conditioning, we believe energy efficiency should be accessible and affordable. Whether you’re ready to install a smart thermostat, upgrade your air quality systems, or simply want to explore your home’s current performance, our team is here to help.

With over 50 years of experience serving homeowners in the Twin Cities, we provide:

  • Smart home system installations

  • Energy-efficient Lennox heating and cooling systems

  • Duct sealing and indoor air quality solutions

  • Honest recommendations tailored to your home and budget

Why Lennox Heat Pumps Are a Smart Choice for Eco-Friendly Heating & Cooling

, , , ,

If you’re looking for a cleaner, more energy-efficient way to heat and cool your home, it might be time to consider a Lennox heat pump. These advanced HVAC systems offer year-round climate control while dramatically reducing your environmental impact—and your energy bills.

As more homeowners prioritize sustainability and long-term efficiency, heat pumps have become one of the greenest HVAC solutions available today. And when you pair that smart technology with the proven performance of Lennox, you get reliable, eco-friendly comfort that lasts for years.

At Marsh Heating & Air Conditioning, we’re proud to offer high-efficiency Lennox heat pumps that are designed to keep your home comfortable through all four Minnesota seasons—while helping you reduce your carbon footprint.

🌎 How Heat Pumps Reduce Environmental Impact

One of the biggest advantages of a heat pump system is how it minimizes harmful emissions and energy waste. Unlike traditional furnaces that burn fuel to generate heat, a heat pump transfers heat using electricity—making it a more sustainable alternative to fossil fuel-based systems.

✔ No Combustion Emissions

Gas furnaces release carbon dioxide (CO₂) and other greenhouse gases through combustion. In contrast, heat pumps move heat rather than create it, meaning zero on-site emissions. This can make a big difference, especially if you’re looking to reduce your home’s overall environmental impact.

✔ Energy-Efficient Heating & Cooling

Heat pumps work by extracting heat from the air—even in cold temperatures—and transferring it indoors. In the summer, the process is reversed to cool your home. Because heat pumps move heat rather than generate it, they use significantly less energy compared to traditional HVAC systems.

Some Lennox heat pumps can deliver up to three times more heating energy than the electrical energy they consume—that’s exceptional efficiency with real savings.

✔ Compatible with Solar Energy

Lennox heat pumps can be paired with solar energy systems for an even greener solution. By generating your own electricity through solar panels, you can essentially heat and cool your home without increasing your utility bills or carbon output. This makes heat pumps a key part of any net-zero or energy-efficient home design.

🌱 Best Lennox Heat Pumps for Eco-Friendly Comfort

Lennox offers a variety of heat pump models that prioritize both performance and sustainability. Here are two top picks for Minnesota homeowners who want to maximize comfort while minimizing energy use:

🌿 Lennox SL25XPV – The Elite in Efficiency

This variable-capacity heat pump is part of Lennox’s Signature® Collection. It adjusts output in small increments to maintain the perfect indoor temperature with minimal energy waste.

  • Up to 24 SEER and 11.8 HSPF for outstanding efficiency

  • Variable-speed operation for ultra-quiet comfort

  • Works seamlessly with iComfort® smart thermostats

  • ENERGY STAR® certified for eco-conscious performance

🌿 Lennox EL18XPV – High Performance, Great Value

The EL18XPV offers smart performance at a more accessible price point, making it a great option for homeowners who want both comfort and value.

  • ENERGY STAR® certified

  • Compatible with solar and smart home systems

  • Delivers reliable year-round comfort with efficient operation

💚 Why Homeowners Love Lennox Heat Pumps

When you upgrade to a Lennox heat pump, you’re not just choosing a sustainable system—you’re also improving your home’s efficiency, comfort, and cost-effectiveness.

✔ Lower Energy Bills

Thanks to their high efficiency ratings, Lennox heat pumps often pay for themselves over time by reducing your monthly utility bills. In regions with moderate climates—or homes designed with good insulation—a heat pump can handle all your heating and cooling needs without the help of a backup furnace.

✔ Less Reliance on Fossil Fuels

Many homeowners are seeking ways to reduce their dependence on natural gas or oil. Heat pumps, especially when powered by solar energy, offer a future-proof solution for home heating and cooling that’s not tied to volatile fuel markets.

✔ All-Season Comfort

From summer heatwaves to snowy Minnesota winters, Lennox heat pumps are built to deliver consistent, reliable performance. Advanced models like the SL25XPV even include low-temperature operation technology, making them suitable for colder climates where traditional heat pumps might struggle.

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.

Lennox Garage Heaters: Keeping Your Workspace Comfortable in Winter

, , ,

Minnesota winters are no joke. When temperatures dip below freezing, most homeowners retreat indoors—but what about your garage? Whether you use your garage for weekend projects, as a personal gym, hobby workspace, or simply to protect your vehicles, it shouldn’t be the coldest room in your home.

With a Lennox garage heater, you can turn a frigid, barely usable garage into a warm, functional space—even in the heart of winter. At Marsh Heating & Air Conditioning, we specialize in installing high-performance garage heaters designed to deliver comfort, efficiency, and reliability throughout the coldest months of the year.

Why You Need a Garage Heater

If you’ve ever tried to start your car on a subzero morning or tinker with a DIY project while your breath fogs in the air, you already know how cold garages can be a problem. Adding a dedicated heating system to your garage comes with several key advantages:

✔ Prevent Equipment Damage and Frozen Pipes

Cold garages aren’t just uncomfortable—they can be damaging. Plumbing lines that run through garage walls are at risk of freezing and bursting, especially during prolonged cold spells. Additionally, tools, paint, batteries, and other materials stored in your garage may not respond well to freezing temperatures.

A garage heater helps maintain a safe ambient temperature, protecting your investments from unnecessary wear or permanent damage.

✔ Create a Comfortable Workspace or Hobby Area

Your garage is more than just a parking spot—it may double as a woodshop, art studio, fitness room, or mechanic’s space. A cold environment discourages use during the winter months, and portable space heaters are often inefficient or unsafe.

A permanently installed Lennox garage heater creates a consistent, safe, and inviting space so you can continue your projects or workouts year-round.

✔ Improve Vehicle Comfort and Performance

Warming your garage also benefits your vehicle. Cold starts are tough on engines, batteries, and fluids. By keeping your garage warmer, you can extend the life of your car and reduce the wear and tear that occurs during harsh Minnesota winters.

What Is an Air Handler? Why the Lennox CBK48MVT Could Be a Game-Changer for Your Home Comfort

, , , ,

If you’re researching ways to improve your home’s heating and cooling efficiency, you’ve likely come across the term air handler. But what exactly is an air handler, and how can it make a difference in your comfort, air quality, and energy bills?

At Marsh Heating & Air Conditioning, we believe in helping homeowners understand the HVAC technology that powers their homes. That’s why we’re excited to spotlight the Lennox CBK48MVT, a top-performing air handler that brings exceptional comfort, quiet performance, and energy savings to any home.

What Is an Air Handler?

An air handler is a critical component of a heating and cooling system, especially in homes that use heat pumps instead of traditional furnaces. Think of it as the indoor companion to your outdoor unit. While the outdoor unit handles the heating or cooling of air (depending on the season), the air handler is responsible for:

  • Moving the conditioned air through your ductwork

  • Regulating temperature and humidity via built-in coils and fans

  • Filtering the air, improving indoor air quality

  • Working seamlessly with heat pumps to deliver year-round comfort

In short, an air handler makes sure the warm or cool air produced by your HVAC system gets where it needs to go—quickly, efficiently, and quietly.

Introducing the Lennox CBK48MVT: Advanced Comfort Starts Here

The Lennox CBK48MVT Air Handler is part of the Lennox Elite® Series, known for offering high-quality performance and smart technology integration. It’s specifically designed to work with communicating heat pumps, providing advanced features that set it apart from standard air handlers.

Here’s how the CBK48MVT stands out and why it may be the perfect addition to your home comfort system:

Key Benefits of the Lennox CBK48MVT

✅ Variable-Speed Technology for Consistent Comfort

Unlike traditional air handlers that turn on and off at full power, the CBK48MVT features variable-speed motor technology. This allows the unit to operate at multiple speeds depending on your home’s current temperature needs.

  • Maintains a more stable indoor temperature

  • Reduces humidity levels more effectively in the summer

  • Eliminates the hot and cold spots common in many homes

With smoother airflow and fewer temperature fluctuations, you’ll enjoy a more comfortable environment year-round.

✅ Quiet Operation

Thanks to its advanced motor and thoughtfully designed components, the CBK48MVT runs significantly quieter than standard models. This makes it ideal for households that prioritize peace and quiet—especially if your unit is located near bedrooms or living areas.

✅ Energy Efficiency that Lowers Bills

The variable-speed motor not only enhances comfort but also uses less electricity, since it doesn’t need to power on and off frequently like a single-speed unit. When paired with a high-efficiency Lennox heat pump, the CBK48MVT can help reduce monthly utility costs and maximize your system’s performance.

✅ Smart System Compatibility

This unit is fully compatible with Lennox’s iComfort®-enabled systems. That means it can communicate with smart thermostats to optimize comfort, energy use, and even maintenance notifications.

When connected with an iComfort® S30 or M30 thermostat, you can monitor and adjust settings from your smartphone, track energy usage, and receive alerts if something’s not quite right with your system.

✅ Improved Indoor Air Quality

The CBK48MVT is built to support air filtration enhancements that trap dust, allergens, and other pollutants. That means cleaner, healthier air throughout your home—especially beneficial for households with pets, allergies, or asthma.

Who Should Consider the Lennox CBK48MVT?

This air handler is ideal for:

  • Homeowners replacing an older air handler that’s inefficient or loud

  • New builds that will use a heat pump or hybrid system

  • Families looking to improve humidity control and energy efficiency

  • Anyone interested in smart home integration for their HVAC system

If your current air handler is struggling to keep up—or if you want to upgrade to a variable-speed system that enhances both comfort and savings—the CBK48MVT is an investment worth considering.

Trust Marsh Heating & Air Conditioning with Your Installation

As a Lennox Premier Dealer, Marsh Heating & Air Conditioning has the experience, tools, and training to install and service advanced air handler systems like the CBK48MVT. We’ll help you determine if this unit is right for your home and pair it with the ideal heat pump or hybrid system for maximum performance.

  • Honest guidance on system compatibility and efficiency

  • Expert installation that meets all manufacturer and safety standards

  • Maintenance plans to keep your system running at peak performance

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
