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 An Outdated Furnace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.

đź’ˇ 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.

Decluttering Your Home: A Room-by-Room Guide to a Cleaner, Healthier Space

, ,

Clutter doesn’t just make your home look messy—it can affect your mental well-being, complicate cleaning routines, and even harm your indoor air quality. When dust and allergens build up around unused items and forgotten corners, they’re constantly circulated through your home—especially if your HVAC system isn’t properly maintained.

By decluttering room by room, you can transform your home into a more breathable, peaceful, and functional space. Here’s how to tackle each area of your home—and how better air quality starts with a cleaner living environment.

Living Room Decluttering
The living room is where most families relax, entertain, and unwind. But it’s also one of the first places to accumulate visual clutter, from tangled cords to stacks of magazines and rarely-used décor.

Try these steps:
âś” Purge outdated magazines, broken remote controls, and unused electronics.
âś” Use decorative storage boxes or ottomans with built-in compartments to hide remotes, chargers, and game controllers.
âś” Tame the cords with cord organizers or zip ties to reduce visual clutter and tripping hazards.
✔ Vacuum carpets and upholstery regularly, and don’t forget behind furniture—these areas trap allergens and dust.

Bonus Tip: Adding a houseplant or two can enhance aesthetics and help purify the air naturally.

Kitchen Decluttering
The kitchen is the heart of the home—but also one of the easiest places for clutter to hide. Over time, cabinets and drawers fill with items we never use, and expired food items can linger in the pantry or fridge.

Here’s how to simplify and refresh:
âś” Clear out expired pantry items, broken appliances, and those four extra spatulas.
âś” Use clear containers or labeled bins to keep shelves tidy and easy to navigate.
✔ Reorganize your “junk drawer” by removing anything that doesn’t belong in the kitchen.
✔ Clean your range hood filters and stovetop ventilation fans—they trap grease, dust, and airborne particles that lower air quality.

Regular cleaning in this space also helps eliminate moisture and odor buildup, which can contribute to mold growth or cooking fumes circulating through your HVAC system.

Bedroom Decluttering
Your bedroom should be a sanctuary—but if it’s filled with unused clothes, cluttered nightstands, and stale air, it can actually disrupt sleep and relaxation.

Refresh your space with these steps:
✔ Sort through your wardrobe, donating anything you haven’t worn in the last year.
âś” Declutter under your bed, a favorite hiding spot for dust bunnies and forgotten items.
✔ Limit decorative clutter—keep your nightstand clean and your dresser top tidy.
âś” Replace HVAC filters in this zone (or throughout the house) for cleaner breathing and better sleep quality.

Keeping your bedroom free from allergens and clutter can make a noticeable difference in your rest and overall wellness.

Bathroom Decluttering
Bathrooms are small but mighty when it comes to clutter accumulation. Between expired products and humidity buildup, they require regular attention to stay clean and healthy.

Clean with purpose:
✔ Toss expired medications, old cosmetics, and samples you’ll never use.
âś” Organize toiletries in labeled baskets or cabinet organizers to keep countertops clear.
âś” Wash or replace bath mats and towels, which trap moisture and bacteria.
âś” Clean ventilation fans and wipe mirrors to improve air circulation and minimize mold growth.

Regular bathroom decluttering supports better hygiene—and improves airflow, especially in smaller spaces prone to moisture.

Improve Your Indoor Air Quality as You Declutter
Decluttering isn’t just about visual appeal—it’s a major step toward improving the indoor air quality (IAQ) of your home.

As you clean, don’t forget to:
âś” Dust and vacuum each room thoroughly, including baseboards and vents.
✔ Replace your HVAC filter every 1–3 months, depending on usage and household needs.
âś” Consider installing an air purification system, especially if you suffer from allergies, asthma, or frequent colds.
✔ Have your ducts inspected and cleaned—clutter can cause buildup around vents and ductwork over time.

By combining your decluttering efforts with HVAC maintenance, you create a fresher, cleaner environment for your entire household.

Let Marsh Heating & Air Conditioning Help Keep Your Home Fresh
At Marsh Heating & Air Conditioning, we know that a clean, clutter-free home is only part of the equation. To truly breathe easier, your air systems need to be clean and functioning efficiently. That’s where we come in.

We offer:

  • Professional HVAC tune-ups to keep your system running smoothly
  • High-efficiency air filters and purifiers to trap allergens and dust
  • Duct cleaning services to remove hidden buildup and improve airflow
  • Humidity control solutions for healthier, balanced air year-round

Declutter your home. Refresh your air. Feel the difference.

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:

âś” 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.

âś” 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.

âś” 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.

Best Lennox Garage Heater Models

Lennox offers a selection of garage heaters to fit both residential and light commercial needs. Here are two top-rated models ideal for Minnesota homeowners:

🔥 Lennox LF24 Garage Heater

The LF24 is designed for residential garages and small workshops. It features:

  • Quiet operation, so it won’t disrupt your work or activities

  • Sealed combustion for safe indoor use

  • Compact size for flexible installation on walls or ceilings

  • Up to 80% thermal efficiency, helping you stay warm without breaking the bank

🔥 Lennox T-Class™ TUA Garage Heater

Need more power for a larger space or commercial-style garage? The T-Class TUA offers:

  • Heavy-duty construction for demanding environments

  • A range of sizes and airflow options to match your exact space

  • High-performance heat exchanger for maximum durability

  • Built-in safety controls and corrosion-resistant components

Whether you’re heating a standard two-car garage or a detached workshop, Lennox has a model to meet your needs.

Key Benefits of a Lennox Garage Heater

âś” Reliable Performance in Extreme Cold

Lennox garage heaters are built for performance—even when outside temperatures drop well below freezing. They heat quickly and maintain consistent temperatures, so you’re never left shivering while you work.

âś” Energy Efficiency

These units are designed to heat your space efficiently, using natural gas or propane to deliver warmth without driving up your utility bills. Compared to electric space heaters, Lennox gas heaters offer better performance and long-term cost savings.

âś” Quiet, Compact, and Flexible Installation

Thanks to smart design, Lennox garage heaters operate quietly—ideal for home environments—and are compact enough to mount on the ceiling or wall, preserving valuable floor space. Their sealed combustion design also improves safety by pulling in outside air for fuel combustion.

Trust Marsh Heating & Air Conditioning for Expert Installation

Installing a garage heater isn’t just about choosing the right unit—it’s about proper sizing, placement, venting, and safety. At Marsh Heating & Air Conditioning, we bring over 50 years of experience to every job, ensuring your system is installed correctly and operates at peak efficiency.

Our certified technicians will:

  • Help you choose the right Lennox model for your garage size and use

  • Handle all venting and gas line connections to meet code

  • Offer ongoing maintenance and support to keep your system running reliably

Stay Warm Where It Matters Most

Don’t let the cold force you out of your garage this winter. Whether you’re working on your next DIY project or just want your car to start without a fight, a Lennox garage heater can transform your garage into a warm, functional space.

Why Indoor Air Quality Matters for Employee Health & Productivity

, , ,

When most businesses think about increasing productivity, they often look at tools, training, or workflow strategies. But there’s another factor that can have a surprisingly powerful effect on performance and well-being: indoor air quality (IAQ).

From open-plan offices to medical facilities and retail environments, IAQ has a direct impact on employee health, cognitive function, and job satisfaction. In fact, poor air quality can lead to increased sick days, reduced focus, and even long-term health complications.

If your workplace is dealing with stale air, excess dust, or inconsistent temperature and humidity, it’s time to look at how your indoor environment may be affecting your bottom line.

1. The Impact of Poor Indoor Air Quality on Employee Health

Every day, your employees are breathing the air that circulates through your HVAC system. If that air is full of dust, mold spores, or volatile organic compounds (VOCs), it can affect their health in both subtle and serious ways.

Common Health Effects Include:

  • Respiratory issues like coughing, wheezing, and sinus congestion

  • Frequent headaches, fatigue, and brain fog

  • Worsening of chronic conditions such as asthma or allergies

According to the EPA, indoor air can be 2 to 5 times more polluted than outdoor air. In tightly sealed office buildings with poor ventilation, contaminants tend to accumulate—leading to a phenomenon known as “sick building syndrome.”

In the long term, poor IAQ can even contribute to serious illnesses and drive up healthcare costs for employers.

2. How Indoor Air Quality Affects Productivity

Clean air does more than just reduce sick days—it also boosts mental clarity, decision-making, and focus.

Studies from institutions like Harvard University have found that employees working in well-ventilated environments with low levels of air pollutants perform better on cognitive tasks compared to those working in poorly ventilated spaces.

Improved IAQ Can Lead To:

  • Higher productivity and output

  • Fewer workplace distractions (less sneezing, coughing, or discomfort)

  • Reduced stress levels and improved mood

In environments where employees feel physically better, they also tend to be more engaged, efficient, and creative. The air your team breathes matters more than you might think.

3. Common Causes of Poor IAQ in Office Settings

Indoor air pollution in commercial buildings can come from a variety of sources—many of them unexpected.

Key Culprits Include:

  • Inadequate ventilation: When fresh air doesn’t circulate, airborne contaminants build up.

  • Neglected HVAC systems: Dirty air filters and poorly maintained components spread dust, allergens, and bacteria.

  • Office furnishings and equipment: Items like carpeting, furniture, and printers often emit VOCs.

  • Humidity issues: High moisture levels lead to mold, mildew, and dust mites, all of which aggravate respiratory conditions.

Even seemingly minor issues like blocked vents or a seldom-cleaned duct system can quietly contribute to poor indoor air quality.

4. Proven Strategies to Improve Indoor Air Quality

Improving workplace air quality doesn’t have to mean a full HVAC overhaul. Often, a few strategic updates and good maintenance practices can go a long way.

Actionable Steps:

  • Upgrade HVAC filters: Use HEPA or MERV 13+ filters to trap fine particles like dust, pollen, and bacteria.

  • Increase ventilation: Consider systems like Energy Recovery Ventilators (ERVs) to bring in fresh air without losing energy efficiency.

  • Schedule regular HVAC maintenance: Seasonal inspections and cleanings ensure optimal airflow and cleanliness.

  • Monitor humidity levels: Aim to keep indoor humidity between 30-50% to minimize mold growth and dust mites.

  • Switch to green cleaning products: Traditional cleaners can emit VOCs—opt for low-emission alternatives.

For even greater control, consider installing indoor air quality monitors to track real-time air quality conditions in your building.

5. The Business Benefits of Better IAQ

Investing in cleaner air doesn’t just protect your employees—it also improves your company’s overall performance and image.

Tangible Business Benefits:

  • Lower healthcare costs: Fewer sick days and doctor visits reduce health insurance claims.

  • Higher employee satisfaction: A comfortable, healthy workspace boosts morale and retention rates.

  • Enhanced corporate reputation: Demonstrating a commitment to sustainability and wellness can attract clients and talent alike.

Good IAQ isn’t just a health concern—it’s a strategic business advantage.

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

âś… 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.

âś… 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.

âś… 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.

âś… 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.

âś… 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.

When you choose Marsh, you get:

  • 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

Fall Home Maintenance Checklist: Get Your Home Ready for Cooler Weather

, , ,

As the leaves begin to change and temperatures start to dip, it’s the perfect time to prepare your home for the colder months ahead. A proactive fall maintenance checklist can help ensure your house stays warm, energy-efficient, and problem-free throughout the winter. Tackling these essential tasks now can also prevent unexpected breakdowns and costly repairs during the peak of the heating season.

Here’s your comprehensive fall home maintenance checklist—with expert tips from Marsh Heating & Air Conditioning, your trusted partner for all things HVAC.

1. Inspect and Clean Your Gutters

Your home’s gutter system plays a vital role in directing rainwater and melting snow away from your roof and foundation. In the fall, gutters often become clogged with leaves, twigs, and debris.

âś” Remove all debris to prevent overflow and ice dams, which can cause serious water damage.
âś” Check downspouts to ensure they drain properly and are angled away from the foundation.
âś” Consider installing gutter guards to minimize future clogs and reduce seasonal maintenance.

Neglected gutters can lead to costly structural damage and mold growth—especially in freeze-thaw climates like Minnesota.

2. Seal Windows and Doors

Cold drafts can easily sneak into your home through small gaps and cracks around windows and doors, causing your heating system to work harder and raising your energy bills.

âś” Apply caulk around window frames, and use weatherstripping on doors to block drafts.
✔ Don’t forget baseboards, attic hatches, and vents, which are common culprits for air leaks.
âś” Use thermal curtains or window film for added insulation during the coldest months.

Proper sealing not only improves comfort but also reduces the strain on your HVAC system—leading to energy savings and better indoor air quality.

3. Check Your Heating System

Before the first deep freeze, it’s important to make sure your furnace or heating system is in good working order.

âś” Test your thermostat to ensure it responds correctly and maintains your desired temperature.
âś” Turn on your furnace for a few minutes and listen for unusual sounds like clanking or screeching, which could signal mechanical issues.
âś” Replace or clean your air filter to improve airflow, system efficiency, and indoor air quality.

The earlier you check, the more time you have to schedule service if repairs or adjustments are needed.

4. Clean Your Fireplace and Chimney

If your home has a fireplace, especially a wood-burning one, now’s the time to prepare it for safe, efficient use.

âś” Clear out ashes and soot from the firebox.
âś” Inspect for creosote buildup, which is highly flammable and should be professionally cleaned.
✔ Schedule a chimney sweep if it hasn’t been cleaned in the past year.

Even if you only use your fireplace occasionally, annual maintenance is important for fire prevention and proper ventilation.

5. Schedule a Professional Furnace Tune-Up

Your furnace is the heart of your home during winter, and a pre-season tune-up ensures it’s ready to handle the months ahead.

âś” A tune-up includes inspecting components, tightening connections, checking fuel lines, and testing for carbon monoxide leaks.
âś” Routine maintenance improves system efficiency, extends the life of your furnace, and helps prevent unexpected breakdowns.
✔ You may also catch small issues early—before they turn into costly repairs on the coldest day of the year.

Upgrade Your Comfort with the Lennox SL22KLV Heat Pump: Smart, Efficient, and Year-Round Savings

, , , ,

For homeowners in Minnesota and beyond, staying comfortable year-round often means relying on both heating and cooling systems. But what if one unit could handle both, while dramatically lowering your energy bills and enhancing your home’s comfort? Enter the Lennox SL22KLV Variable-Capacity Heat Pump—a premium HVAC solution designed for maximum efficiency, minimal noise, and seamless smart home integration.

At Marsh Heating & Air Conditioning, we’re proud to offer cutting-edge Lennox products that prioritize both performance and energy savings. If you’re considering an HVAC upgrade, here’s why the SL22KLV should be at the top of your list.

What Is the SL22KLV Heat Pump?

The Lennox SL22KLV is part of the Signature® Collection, Lennox’s top-tier lineup of high-efficiency heating and cooling systems. This model is a variable-capacity heat pump, which means it provides both heating and cooling—and automatically adjusts its output in small increments to match your home’s exact needs.

Unlike traditional heat pumps that operate at full blast or not at all, the SL22KLV uses variable-speed technology to maintain a consistent indoor temperature while consuming as little energy as possible. Whether you’re dealing with summer heat or a chilly fall evening, this unit delivers comfort that adapts to you.

Key Benefits of the Lennox SL22KLV

âś… Exceptional Energy Efficiency

âś… Variable-Capacity Operation for Precise Comfort

Unlike single- or two-stage systems that turn on and off repeatedly, the SL22KLV runs at the exact speed needed to maintain your desired temperature. This reduces temperature swings, improves humidity control, and enhances overall comfort—especially in homes where consistent heating or cooling is a challenge.

✅ Quiet Performance with SilentComfort™ Technology

No one wants their HVAC system to be the loudest thing in the house—or outside it. The SL22KLV uses SilentComfort™ technology to reduce operational noise to as low as 58 decibels. That’s quieter than a normal conversation and significantly quieter than many standard heat pumps.

âś… Smart Home Integration

The SL22KLV is iComfort®-enabled, allowing full integration with the iComfort® S30 Smart Thermostat and popular smart home platforms. You’ll be able to control your home’s climate remotely, set schedules, and even receive maintenance alerts—all from your smartphone or tablet.

Smart features like geofencing, Smart Away™, and Allergen Defender work in the background to optimize comfort, reduce energy use, and improve indoor air quality based on your habits and environment.

How the SL22KLV Improves Your Home

The Lennox SL22KLV is ideal for:

  • Year-round comfort with one system that handles both heating and cooling

  • Homeowners seeking lower utility bills and reduced environmental impact

  • Smart home users looking to automate and personalize indoor climate control

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 Ultimate Cooling Efficiency with the Lennox SL25KCV Air Conditioner

, , , ,

When summer temperatures climb in Minnesota, your air conditioner becomes your home’s MVP. But not all AC units are created equal. If you’re looking for an ultra-efficient, whisper-quiet, and smart-home-ready cooling solution, the Lennox SL25KCV stands out as one of the best options on the market today.

As part of the Lennox Signature® Collection, the SL25KCV is built with advanced technology that offers not just relief from the heat—but also long-term energy savings and precise temperature control. At Marsh Heating & Air Conditioning, we proudly install the SL25KCV for homeowners who want peak comfort without compromising efficiency.

What Makes the Lennox SL25KCV Exceptional?

The SL25KCV is Lennox’s most efficient and quietest central air conditioner. With a SEER rating of up to 28, this system is designed to deliver high-performance cooling while dramatically lowering your energy bills.

It also features variable-capacity operation, meaning it can adjust its output in small increments rather than running full blast all the time. This allows it to maintain a consistent indoor temperature, reduce energy waste, and eliminate hot and cold spots throughout the home.

Key Benefits of the Lennox SL25KCV

âś… Unmatched Energy Efficiency (Up to 28 SEER)

The Seasonal Energy Efficiency Ratio (SEER) measures how efficiently an air conditioner cools your home. The higher the SEER rating, the more efficient the system. The SL25KCV’s 28 SEER rating makes it one of the most energy-efficient AC units available.

If you’re upgrading from an older unit with a SEER of 10 or 13, the SL25KCV can cut your cooling costs by more than half. That’s real savings you’ll notice all summer long.

âś… Variable-Capacity Comfort

Rather than turning on and off frequently like traditional AC units, the SL25KCV uses variable-speed technology to adjust its output based on your cooling needs. This leads to:

  • More consistent temperatures

  • Quieter operation

  • Less energy consumption

  • Improved humidity control

This kind of advanced comfort is perfect for Minnesota summers, where temperatures and humidity can vary dramatically from day to day.

✅ SilentComfort™ Technology

Say goodbye to noisy outdoor units. The SL25KCV is Lennox’s quietest central air conditioner ever, thanks to its SilentComfort™ Technology. Engineered sound-dampening features ensure that the unit runs quietly—even at higher capacities—so you can enjoy your summer without the background hum.

✅ iComfort®-Enabled for Smart Home Integration

When paired with the iComfort® S30 Smart Thermostat, the SL25KCV becomes part of your intelligent home ecosystem. It allows for:

  • Remote temperature control via smartphone or tablet

  • Integration with Amazon Alexa, Google Assistant, and Apple HomeKit

  • Features like Smart Away™, which adjusts temperatures automatically when you leave

  • Allergen Defender, which reacts to air quality alerts in your area

This connectivity puts complete comfort control right in your hands, whether you’re at home or away.

âś… Environmentally Responsible

The SL25KCV uses R-410A refrigerant, which is chlorine-free and does not deplete the ozone layer. Combined with its low energy consumption, this unit is an eco-conscious choice for homeowners who want to reduce their carbon footprint without sacrificing comfort.

Is the SL25KCV Right for Your Home?

This air conditioner is ideal for:

  • Homeowners upgrading from an older or inefficient system

  • Families who want a quieter, more consistent cooling experience

  • Smart home enthusiasts who want full thermostat integration

  • Anyone focused on reducing long-term energy costs

If you’re planning to stay in your home for years to come, the SL25KCV is an investment that pays off in comfort, savings, and reliability.
