Tips and Advice

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.

  • Installing smart thermostats that optimize comfort and efficiency

The Hidden Costs of an Inefficient HVAC System

, , , , ,

Your HVAC system plays a crucial role in maintaining comfort in your home, but an inefficient system can lead to unexpected expenses. While many homeowners focus on upfront costs, hidden inefficiencies can quietly drain your wallet over time.
