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.

What Makes the Lennox iComfort® Thermostat Smart?

Unlike traditional thermostats that require constant adjustments, iComfort smart thermostats learn your preferences and adjust automatically. They also offer intuitive, app-based controls and real-time responsiveness to your environment, giving you a seamless, energy-saving experience.

✔ Adaptive Learning

Over time, the iComfort thermostat learns your schedule and temperature preferences, adjusting automatically so you’re always comfortable without lifting a finger. Whether you’re home or away, the system optimizes heating and cooling for maximum efficiency.

✔ Remote Control Access

With the iComfort app, you can adjust your home’s temperature from anywhere using your smartphone or tablet. Going on vacation? Headed home early? You’re always in control, even when you’re not home.

✔ 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

Lennox offers several smart thermostat models, each designed to meet different household needs and budgets. Here’s a quick breakdown of their most popular options:

  • Monitors air quality and alerts you to indoor pollutants

How the iComfort Smart Thermostat Saves You Money

Installing a Lennox iComfort thermostat is one of the easiest and most effective ways to lower your utility bills. Here’s how:

💰 Reduced Energy Waste

The system learns when you’re home, asleep, or away, and adjusts heating and cooling accordingly. No more heating an empty house or forgetting to turn down the thermostat at night.

💰 Lower Heating & Cooling Costs

By running your system more efficiently and adjusting based on current conditions, you’ll use less energy to stay comfortable—especially during extreme Minnesota winters or hot summer days.

💰 Extended HVAC Lifespan

Because the iComfort thermostat prevents your system from running unnecessarily, it helps reduce wear and tear on your furnace and air conditioner. That means fewer repairs and a longer system lifespan, saving you money on maintenance and replacements.

💰 Informed Decisions

With energy usage reports and maintenance alerts, the thermostat keeps you informed about your system’s performance—allowing you to spot inefficiencies before they become expensive issues.

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.

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:
✔ Purge outdated magazines, broken remote controls, and unused electronics.
✔ Use decorative storage boxes or ottomans with built-in compartments to hide remotes, chargers, and game controllers.
✔ 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:
✔ Clear out expired pantry items, broken appliances, and those four extra spatulas.
✔ 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.
✔ 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.
✔ 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.
✔ Organize toiletries in labeled baskets or cabinet organizers to keep countertops clear.
✔ Wash or replace bath mats and towels, which trap moisture and bacteria.
✔ 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:
✔ Dust and vacuum each room thoroughly, including baseboards and vents.
✔ Replace your HVAC filter every 1–3 months, depending on usage and household needs.
✔ 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:

✔ 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.

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

✔ 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.

✔ 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.

✔ 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.

📞 Call Marsh Heating & Air Conditioning today at 763.536.0667 or visit MarshHeating.com to schedule your garage heater installation before the cold hits.

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

Why Choose Marsh Heating & Air Conditioning?

At Marsh Heating & Air Conditioning, we’ve been helping Twin Cities homeowners stay warm since 1974. Our NATE-certified technicians are experts in furnace installation and will help you choose the best system for your home, lifestyle, and budget.

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

📞 Call us today at 763.536.0667 or visit MarshHeating.com to schedule your HVAC inspection and get your air—and your pantry—back in shape.

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.

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.

How to Reduce Your Energy Bills During Extreme Weather

, , , ,

Living in Minnesota means dealing with both bitterly cold winters and hot, humid summers. Unfortunately, extreme temperatures can lead to a dramatic increase in utility bills. Heating and cooling account for the majority of home energy use, and without the right strategies, it’s easy to overpay. The good news? You can take several simple steps to reduce your energy bills—without sacrificing comfort.

Here’s how to stay cozy in the winter and cool in the summer while keeping your energy costs in check.

1. Install a Programmable or Smart Thermostat

One of the most effective ways to reduce energy use is by upgrading your thermostat. Programmable and smart thermostats allow you to control your home’s temperature based on your daily schedule.

  • Set the temperature lower when you’re away in the winter or higher in the summer.

  • Automatically adjust settings at night when everyone is asleep.

  • Avoid running your HVAC system unnecessarily when no one is home.

Smart Tip: Lennox’s iComfort® smart thermostat goes a step further by learning your habits over time. It adjusts temperatures automatically for optimal energy savings and can even be controlled remotely using your smartphone.

2. Seal Air Leaks Around the Home

Air leaks are one of the most common reasons for energy loss, especially in older homes.

  • Use weatherstripping for doors and windows.

  • Apply caulk around window frames, attic hatches, plumbing penetrations, and electrical outlets.

  • Don’t forget to check the basement and garage, where drafts often go unnoticed.

By sealing these leaks, you’ll prevent cold air from creeping in during the winter and keep your air-conditioned air inside during the summer—both of which lighten the load on your HVAC system and reduce your energy usage.

3. Improve Insulation Where Necessary

Insulation is your home’s first line of defense against extreme temperatures.

  • Attic insulation is especially important—heat rises, and without proper insulation, it escapes quickly.

  • Insulating your basement and exterior walls helps maintain a consistent indoor temperature.

  • Use spray foam, fiberglass, or cellulose insulation to fill gaps and block heat transfer.

When your home is well-insulated, your heating and cooling system doesn’t have to work as hard to maintain the desired temperature—resulting in significant energy savings.

4. Schedule Regular HVAC Maintenance

Your HVAC system is like any other machine—it performs better when properly maintained.

  • Schedule professional tune-ups in spring and fall to prepare for the intense seasons.

  • Replace your air filters monthly or as recommended, especially during peak usage months.

  • Clean coils and check for issues like low refrigerant or leaky ducts that can cause energy waste.

Preventative maintenance not only extends the life of your equipment but also ensures that it’s operating at peak efficiency—helping you avoid unexpected breakdowns and higher energy bills.

5. Use Ceiling Fans Strategically

Ceiling fans don’t just add a breeze—they help circulate air more efficiently, which can reduce your reliance on your HVAC system.

  • In winter, set fans to rotate clockwise at a low speed. This pushes warm air down from the ceiling and helps maintain an even room temperature.

  • In summer, reverse the fan direction to counterclockwise for a cooling effect that allows you to raise the thermostat a few degrees without feeling a difference.

Just be sure to turn off fans when you leave the room—fans cool people, not spaces.
