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 An Outdated Furnace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.

Smart Home Features of Lennox Thermostats

Lennox thermostats go far beyond traditional temperature control. These devices are equipped with advanced features that allow you to take full command of your home’s comfort from anywhere—and with minimal effort.

✔ Voice Control Integration

Lennox thermostats can be controlled using your favorite smart assistants, including Amazon Alexa, Google Assistant, and Apple Siri (via Apple HomeKit integration). This means you can simply say, “Set the temperature to 72 degrees,” without lifting a finger. It’s a small feature that adds a big layer of convenience—especially when you’re cooking, relaxing, or heading to bed.

One of the most innovative features available is geofencing. The thermostat detects when you leave or approach your home using your phone’s location. It then adjusts the temperature automatically—saving energy while you’re away and ensuring comfort when you return. No more wasting energy heating or cooling an empty house.

✔ Air Quality Monitoring

Comfort isn’t just about temperature. Some Lennox smart thermostats can also monitor indoor air quality by detecting humidity levels and airborne pollutants. When paired with compatible Lennox air purification systems, your thermostat can automatically activate filtration or ventilation to keep your indoor environment fresh and healthy.

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.
