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

How Humidity Affects Your HVAC System & Home Comfort

, , , , ,

Humidity plays a crucial role in maintaining a comfortable and efficient home environment. Too much or too little humidity can impact your HVAC system’s performance and your overall well-being. Here’s how humidity levels affect your home and what you can do to maintain the perfect balance.

The Ideal Indoor Humidity Level

For optimal comfort and HVAC efficiency, indoor humidity levels should be maintained between 30-50%. Levels outside this range can cause various problems for both your home and health.

Effects of High Humidity on Your Home and HVAC System

  • Increased Energy Costs: Excess moisture makes your air conditioner work harder, consuming more energy.
  • Mold and Mildew Growth: High humidity encourages mold and mildew, which can lead to health issues and damage to your home.
  • Poor Air Quality: Excessive moisture promotes dust mites and allergens, affecting indoor air quality.
  • Uncomfortable Living Conditions: A sticky, damp atmosphere can make your home feel warmer than it actually is, leading to excessive AC use.

Effects of Low Humidity on Your Home and HVAC System

  • Dry and Itchy Skin: Low moisture levels can cause skin irritation, dry eyes, and respiratory discomfort.
  • Increased Static Electricity: Low humidity can lead to annoying static shocks and damage to electronics.
  • Damage to Wood and Furniture: Insufficient moisture can cause wood to crack, warp, or become brittle.
  • HVAC Inefficiency: Dry air makes it harder for your heating system to maintain comfortable temperatures, increasing energy costs.

How Your HVAC System Regulates Humidity

  • Air Conditioners: Remove excess moisture from the air while cooling your home.
  • Dehumidifiers: Help control excessive moisture in humid climates or during summer months.
  • Humidifiers: Add moisture to the air in dry winter months to prevent dryness-related issues.

When to Call an HVAC Professional

If you experience persistent humidity issues, your HVAC system may need maintenance or an upgrade. A professional technician can assess your system’s performance and recommend solutions to ensure balanced indoor humidity.

Ensure Year-Round Comfort with Proper Humidity Control Maintaining the right humidity levels is essential for both comfort and HVAC efficiency. If you’re experiencing humidity problems, contact Marsh Heating & Air Conditioning today. With over 50 years of experience, we can help you find the perfect solutions for a healthier and more comfortable home.

How to Allergy-Proof Your Home—And Why Your HVAC System Matters

, , , , ,

If spring and fall leave you sneezing, congested, or with watery eyes—even indoors—you’re not alone. Allergies don’t stop at the door, and for many homeowners, indoor air can actually be more polluted than what’s outside. But the good news is, with a few smart changes and the right HVAC solutions, you can dramatically reduce allergens in your home.

At Marsh Heating & Air Conditioning, we understand the challenges Minnesota families face when it comes to indoor air quality. With over 50 years of experience serving local homeowners, we know how to help you breathe easier—season after season.

Why Indoor Allergies Are So Common

Allergens like pollen, dust mites, pet dander, mold spores, and volatile organic compounds (VOCs) can accumulate indoors—especially in tightly sealed homes designed for energy efficiency. While that efficiency helps with heating and cooling costs, it also means airborne irritants get trapped inside, circulating through your HVAC system.

If your HVAC system isn’t optimized to filter, clean, and properly circulate air, those allergens keep coming back—leading to symptoms like:

  • Nasal congestion
  • Itchy or watery eyes
  • Coughing and wheezing
  • Headaches and fatigue

Top Ways to Allergy-Proof Your Home

  1. Change Your HVAC Filters Regularly

A clean filter is your first line of defense. Standard filters should be replaced every 1–3 months, but allergy sufferers should consider upgrading to high-efficiency pleated filters (MERV 11–13) or even HEPA filters if your system allows it.

  1. Invest in Whole-Home Air Purification

Portable purifiers help in single rooms, but whole-home systems are more effective for consistent, house-wide protection. The Lennox PureAir™ Air Purification System removes over 99% of airborne particles, including pollen, mold spores, dust, pet dander, and even airborne viruses and bacteria.

This system:

  • Works silently with your HVAC system
  • Breaks down odors and VOCs
  • Requires minimal maintenance

It’s one of the most comprehensive air purification solutions available—and we install them right here at Marsh Heating.

  1. Control Indoor Humidity

Dust mites and mold thrive in high humidity, while dry air can irritate sinuses. Maintaining your home’s humidity between 30% and 50% helps reduce allergens and supports respiratory health.

Lennox Healthy Climate® humidifiers and dehumidifiers work in tandem with your HVAC system to automatically balance humidity levels based on your needs and the season.

  1. Clean Your Ducts (When Necessary)

Over time, ducts can accumulate dust, debris, and allergens. While not every home needs duct cleaning regularly, if your system hasn’t been checked in years—or if you’ve recently renovated—it’s a good idea to have a professional inspection.

  1. Keep Up with Maintenance

An unmaintained HVAC system can become a breeding ground for bacteria and mold. Schedule annual maintenance with Marsh Heating to ensure your system is clean, efficient, and working in your favor—not against it.

Simple Daily Habits That Help

In addition to optimizing your HVAC system, small lifestyle changes can help reduce allergy symptoms:

  • Remove shoes at the door to keep outdoor allergens out
  • Wash bedding weekly in hot water
  • Use an allergen-proof mattress cover
  • Bathe pets regularly to reduce dander
  • Vacuum often with a HEPA-filter vacuum
  • Wipe down hard surfaces to remove dust and pollen

Allergy Relief Starts with Better Air—And the Right Partner

When it comes to reducing indoor allergens, your HVAC system plays a major role—but it takes more than just changing your filter. From installing air purification and humidity control systems to performing regular maintenance, Marsh Heating & Air Conditioning is here to help you create a cleaner, healthier home.

We are proud to be a locally owned company serving Minnesota families for over five decades. As a trusted Lennox dealer, we provide access to industry-leading indoor air quality products that make a real difference.

Refrigerant Innovations: The Future of Eco-Friendly HVAC Systems

, ,

As environmental concerns grow, the HVAC industry is evolving with new refrigerant innovations designed to reduce carbon footprints and improve energy efficiency. Traditional refrigerants have been linked to ozone depletion and global warming, prompting the development of more sustainable alternatives. Here’s what you need to know about the latest advancements in refrigerant technology.

The Shift Away from R-22 and High GWP Refrigerants

For decades, R-22 (Freon) was widely used in air conditioning and refrigeration systems. However, due to its ozone-depleting potential (ODP) and high global warming potential (GWP), it has been phased out and replaced with more environmentally friendly options. Since January 1, 2020, the production and import of R-22 have been banned in the U.S., making retrofitting and upgrading systems essential.

The Rise of R-410A and Its Successor

  • R-410A has been the primary replacement for R-22 due to its zero ozone depletion potential and improved efficiency.
  • However, R-410A still has a relatively high GWP, leading to the search for even better alternatives.

Next-Generation Low-GWP Refrigerants

Several new refrigerants are emerging with lower environmental impact, including:

  • R-32: A promising alternative to R-410A with significantly lower GWP and enhanced energy efficiency.
  • R-454B (Puron Advance): Expected to replace R-410A in many HVAC systems, offering a reduction in carbon emissions.
  • CO2 (R-744): A natural refrigerant with zero ODP and extremely low GWP, used in specialized applications.
  • Hydrocarbons (HCs) like R-290 (Propane): Extremely low GWP but requires safety precautions due to flammability.

Benefits of Upgrading to a Low-GWP Refrigerant System

  • Lower Carbon Footprint: Reduced environmental impact through lower emissions.
  • Improved Energy Efficiency: Many new refrigerants allow HVAC systems to consume less energy, lowering utility bills.
  • Regulatory Compliance: New refrigerants meet stricter EPA and international environmental standards.
  • Future-Proofing Your HVAC System: Investing in a system compatible with next-gen refrigerants ensures long-term savings and reduced maintenance costs.

What Homeowners Should Consider

If you have an older HVAC system that still uses R-22 or an outdated refrigerant, now is the time to consider an upgrade. Retrofitting or replacing your system with one that supports newer, eco-friendly refrigerants can improve performance and ensure compliance with environmental regulations.

Professional Installation and Guidance

Choosing the right refrigerant for your home requires expert advice. A professional HVAC technician can assess your system, recommend upgrades, and ensure safe and efficient installation.

Make the Switch to Eco-Friendly Cooling

As refrigerant technology advances, upgrading to a more sustainable HVAC system can help protect the environment while enhancing home comfort and efficiency. If you’re ready to explore eco-friendly cooling solutions, Marsh Heating & Air Conditioning is here to help. With over 50 years of experience, we provide expert recommendations on the latest refrigerant innovations. Contact us today!

Discover Year-Round Comfort and Efficiency with the Lennox LRP15GEK Packaged Unit

, , , ,

When it comes to heating and cooling your home, choosing the right system can make all the difference in comfort, efficiency, and peace of mind. For homeowners who want reliable performance, space-saving design, and energy-smart operation, the Lennox® LRP15GEK packaged unit delivers on all fronts.

At Marsh Heating & Air Conditioning, we’re proud to offer innovative Lennox products that improve how our customers live and feel in their homes. If you’re considering a packaged unit for a new build or a replacement system, here’s why the LRP15GEK could be the perfect solution for your comfort and budget.

What Is a Packaged Unit?

Unlike traditional HVAC systems that separate heating and cooling equipment (typically placing the furnace indoors and the AC outside), a packaged unit combines all components into a single cabinet. This all-in-one design makes it ideal for homes with limited indoor space or where rooftop or ground-level installation is preferred.

The Lennox LRP15GEK is a gas/electric packaged unit, which means it includes both a high-efficiency gas furnace and an electric air conditioner in one streamlined system. It provides heating during the cold months and cooling during the summer, using the most efficient energy source for each season.

Key Benefits of the Lennox LRP15GEK

✅ All-in-One Convenience

The LRP15GEK simplifies HVAC installation and maintenance. With all components housed in a single outdoor unit, there’s no need to install separate systems inside your home. This can be a major advantage for homeowners with smaller basements or utility rooms, or those seeking to free up space for storage or other uses.

✅ High-Efficiency Performance

With an AFUE rating of up to 81% and a SEER rating of up to 15, the LRP15GEK offers solid efficiency that translates into lower utility bills compared to older or less efficient systems. That means less wasted energy and more cost savings over time.

✅ Reliable Lennox Engineering

Backed by the trusted Lennox brand, the LRP15GEK is engineered for long-term reliability and consistent performance. It features a durable scroll compressor, known for quiet operation and efficiency, and a high-efficiency blower motor that helps maintain steady airflow and comfort throughout the home.

✅ Quiet, Consistent Comfort

No one wants their HVAC system to be noisy or disruptive. The LRP15GEK is designed with sound-reducing features that keep your home peaceful while it runs. Its gas heat provides consistent warmth in winter, while the electric cooling delivers reliable comfort during hot Minnesota summers.

✅ Compact Footprint

Its compact design allows for flexible installation, whether on the ground beside your home or on the rooftop. The unit’s size and all-in-one nature make it especially attractive for smaller lots or homes where traditional HVAC layouts may not be practical.

✅ Simplified Maintenance

Because all components are housed in one unit, seasonal maintenance is easier and often quicker than servicing separate systems. This can help reduce long-term repair costs and improve service efficiency—especially when you’re enrolled in a maintenance plan from Marsh Heating & Air Conditioning.

Who Should Consider the LRP15GEK?

The Lennox LRP15GEK is an excellent choice for:

  • Homeowners with space constraints, including townhomes, manufactured homes, or homes with limited indoor utility space

  • New construction or retrofit projects, where simple installation is a plus

  • Anyone looking to upgrade from an older, inefficient packaged system

  • Homeowners wanting one easy-to-maintain unit that offers year-round comfort

Whether you’re heating your home through brutal Minnesota winters or cooling off during a humid summer day, the LRP15GEK ensures consistent indoor temperatures with energy-conscious performance.

Time to Clean Your Pantry: How to Organize and Declutter for a Healthier Kitchen

,

Spring is a time of renewal, and one of the best places to start your seasonal refresh is the kitchen pantry. Over time, pantries tend to become cluttered with half-used containers, expired foods, and hard-to-reach items that get forgotten in the back. A disorganized pantry not only makes cooking more frustrating, but it can also contribute to food waste, attract pests, and even affect your home’s air quality.

Whether you’re doing a deep spring clean or just trying to create a more efficient kitchen routine, here’s a step-by-step guide to cleaning out your pantry and creating a space that supports healthy living—and fresher air.

Step 1: Empty and Sort Everything

The first step in tackling pantry clutter is to take everything out. Yes, everything.

  • Remove all food and storage containers from your shelves.

  • Group similar items together—think grains, pasta, canned goods, spices, baking supplies, snacks, etc.

  • Check expiration dates and toss anything that’s past its prime, stale, or damaged.

  • Don’t forget to inspect opened bags and boxes—especially cereals and snacks—for signs of pests or spoilage.

Sorting your pantry helps you take inventory of what you have and sets the stage for smarter storage. You might be surprised to find duplicates, or realize you’ve been buying items you already own.

Step 2: Clean and Sanitize Shelves and Containers

With your pantry emptied, now’s the perfect time to give everything a good wipe-down.

  • Use a mild disinfectant or natural cleaner to clean shelves, paying close attention to corners where dust and crumbs collect.

  • Vacuum or sweep out loose debris before wiping.

  • Wash any reusable containers, spice jars, or bins you plan to put back into the pantry.

Cleaning now helps prevent mold, pests, and contamination—keeping your food fresher and safer in the long run.

Step 3: Organize with Smart Storage Solutions

A well-organized pantry not only looks great, but it also makes cooking and meal planning easier.

  • Use clear storage bins and containers so you can see what you have at a glance.

  • Label everything—especially dry goods like flour, sugar, oats, and rice—to avoid confusion and overbuying.

  • Store frequently used items at eye level and place bulk items or less-used ingredients on higher or lower shelves.

Don’t forget vertical space! Use stackable containers or shelf risers to maximize storage and keep things accessible.

Step 4: Address Pantry Air Quality

Your pantry may be small, but it’s still part of your home’s overall indoor environment—and poor air quality can affect your food’s shelf life.

  • Check for signs of moisture or humidity, such as condensation, rusting cans, or sticky shelves.

  • Look for mold, mildew, or pest droppings, which may indicate poor ventilation or a moisture issue.

  • Consider using a dehumidifier, especially in humid months or if your pantry is located near a bathroom or exterior wall.

Good air circulation helps prevent food from spoiling prematurely and keeps your pantry smelling clean and fresh.

Step 5: Don’t Forget the Rest of Your Home’s Air

A clean pantry is a great step toward a healthier kitchen, but your home’s air quality depends largely on your HVAC system. If your furnace or air conditioner is dusty, clogged, or overdue for service, it can circulate stale, polluted air throughout every room—including the pantry.

Here’s how your HVAC system affects your pantry and overall air quality:

  • Dust and allergens build up in ducts and filters, especially if neglected during seasonal changes.

  • Moisture or humidity issues in your HVAC system can lead to condensation or mold, which may affect both air and food quality.

  • Poor airflow in your home can lead to temperature imbalances, causing some rooms to be too hot or too cold—affecting how well your pantry preserves food.

Call Marsh Heating & Air Conditioning for an Air Quality Checkup

At Marsh Heating & Air Conditioning, we’re not just here to help you stay warm or cool—we’re here to help you breathe better and live more comfortably. Our team offers:

  • HVAC inspections to assess air quality and system efficiency

  • Duct cleaning and filter replacement to reduce allergens and improve airflow

  • Dehumidification solutions for moisture-prone areas like pantries and basements

Reliable Comfort in Every Room: Why the Lennox GWB9-IH Boiler Is a Smart Home Upgrade

, , , , , ,

When Minnesota’s winter weather hits hard, homeowners need a dependable heating solution that delivers consistent warmth, energy efficiency, and long-lasting performance. For those with hydronic heating systems or looking to upgrade their existing boiler, the Lennox® GWB9-IH Boiler offers a smart, reliable option designed for both comfort and savings.

At Marsh Heating & Air Conditioning, we understand the importance of staying warm without overpaying on energy bills. That’s why we proudly recommend Lennox heating products like the GWB9-IH, engineered for superior performance and peace of mind.

What Is the Lennox GWB9-IH Boiler?

The GWB9-IH Boiler is a high-efficiency, gas-fired water boiler from Lennox. Designed for homes with radiant or hydronic heating systems, this unit efficiently heats water and circulates it through your home’s radiators or underfloor tubing to provide clean, comfortable heat.

Unlike forced-air systems, boilers offer a quiet, dust-free way to heat your home. The GWB9-IH delivers on that promise—and more—with modern technology and high-quality construction.

Key Features & Benefits

✅ Up to 90% AFUE Efficiency

AFUE (Annual Fuel Utilization Efficiency) measures how much fuel a system converts into usable heat. The GWB9-IH boasts up to 90% AFUE, meaning 90 cents of every dollar spent on fuel goes directly toward heating your home. That’s a significant improvement over older boilers, which often waste 30% or more of the fuel they consume.

✅ Cast-Iron Heat Exchanger for Longevity

This boiler is built to last. Its cast-iron heat exchanger is known for durability and heat retention, ensuring steady performance year after year. It’s a perfect match for Minnesota’s harsh winters, when reliable heat is a must.

✅ Electronic Ignition for Fuel Savings

Unlike outdated systems that keep a pilot light burning around the clock, the GWB9-IH uses an electronic ignition system. This feature lights the burners only when needed—saving energy and reducing fuel waste.

✅ 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.

✅ Sealed Combustion System

The sealed combustion system draws air from outside rather than from inside your home. This improves indoor air quality and enhances energy efficiency, particularly in tightly insulated or newer homes.

Is a Boiler Right for Your Home?

Boilers offer several advantages over traditional forced-air systems:

  • Even, radiant heat that eliminates drafts and cold spots

  • Quieter operation, with no noisy fans or blowing air

  • Better air quality, with no dust or allergens being circulated

If your home already uses baseboard heating or in-floor radiant heat, upgrading to the GWB9-IH is a seamless improvement that enhances both comfort and efficiency.

Why Choose Marsh Heating & Air Conditioning?

At Marsh Heating & Air Conditioning, we’ve been helping Twin Cities homeowners stay warm and save energy for over 50 years. Our expert technicians are trained in boiler installation, maintenance, and repair, ensuring your Lennox GWB9-IH Boiler is installed correctly and built to perform.

Common Energy-Wasting Habits You Need to Stop

, , ,

For many homeowners, high energy bills are just accepted as part of daily life—especially during the cold Minnesota winters or humid summer months. But what if some of that cost could be avoided? The truth is, many households engage in small, everyday habits that waste energy without even realizing it.

By breaking these habits, you can significantly lower your utility bills, reduce strain on your HVAC system, and lessen your environmental footprint. Here are some of the most common energy-wasting behaviors—and what to do instead.

1. Leaving the Thermostat Set Too High or Too Low

Setting your thermostat too aggressively is one of the most common (and costly) energy mistakes. Many people believe that cranking the heat in winter or blasting the AC in summer will provide quicker comfort—but all it really does is overwork your HVAC system.

Instead:

  • In winter, set your thermostat to 68°F when you’re home and lower it a few degrees at night or when you’re away.

  • In summer, aim for 78°F while you’re home and bump it up when you’re out.

  • Better yet, invest in a smart thermostat, like the Lennox iComfort®, which automatically adjusts based on your habits and preferences—saving energy without sacrificing comfort.

2. Ignoring Air Filter Changes

Your HVAC system relies on proper airflow to operate efficiently. When filters become clogged with dust, dirt, and debris, your system must work harder to move air through the ducts, using more energy in the process.

What to do:

  • Check your filter monthly, especially during peak heating or cooling seasons.

  • Replace it every 1–3 months, or more often if you have pets or allergies.

  • Consider high-efficiency filters that trap more particles without reducing airflow.

Clean filters mean better performance, better air quality, and lower energy bills.

3. Heating or Cooling an Empty House

Why pay to heat or cool your home when no one’s there to enjoy it? This is a common habit that can cost homeowners hundreds of dollars per year in wasted energy.

How to fix it:

  • Adjust your thermostat settings when you leave for work, vacation, or even just a few hours.

  • Use your system’s eco-mode or set up schedules to avoid unnecessary heating and cooling.

  • A Lennox smart thermostat can take this a step further by detecting your location and making adjustments automatically.

Not only will you save money, but you’ll also come home to comfort—without the waste.

4. Blocking Vents and Registers

Sometimes energy waste isn’t about settings—it’s about airflow. When furniture, rugs, or curtains block air vents and registers, your system can’t distribute air evenly. This forces it to work harder to achieve the desired temperature.

Energy-saving tip:

  • Make sure all vents and registers are clear of obstructions.

  • Periodically vacuum dust and debris around registers to ensure full airflow.

  • Consider a home airflow evaluation to check for balance issues in multi-story homes.

Even small obstructions can reduce your system’s efficiency and increase your energy usage.

5. Skipping Regular HVAC Maintenance

Your heating and cooling system is a major investment, and like any machine, it needs routine care to function properly. Skipping maintenance can lead to lower efficiency, more breakdowns, and higher energy bills.

Stay ahead by:

  • Scheduling seasonal tune-ups in spring and fall.

  • Having a professional inspect, clean, and test your system.

  • Signing up for a maintenance plan to keep your HVAC running smoothly year-round.

Regular maintenance can extend your system’s lifespan and ensure it operates at peak efficiency—especially when you need it most.
