A dirty air filter is like forcing your furnace to breathe through a clogged straw—it has to work harder, use more energy, and ultimately, it won’t last as long.
✅ How Often to Change It in Winter?

• Every 30-60 days (or more often if you have pets or allergies).
• Check the filter monthly—if it looks gray and packed with dust, swap it out.

💡 Pro Tip: Upgrade to a high-efficiency pleated filter (MERV 8-12) for better airflow and indoor air quality.

❄️ 2. Keep Your Vents and Registers Clear
Blocked vents = poor airflow. If furniture, rugs, or curtains are covering your registers, your furnace has to work twice as hard to circulate warm air.
✅ What to Do:

• Keep all vents open (closing vents actually makes your system less efficient).
• Move furniture and objects away from air registers and return vents.
• Vacuum dust and pet hair from vents every few weeks.

💡 Pro Tip: If you have rooms that are always colder, check if your ductwork needs balancing—a quick HVAC adjustment can solve uneven heating.

❄️ 3. Use a Programmable or Smart Thermostat
Your thermostat controls everything—and if you’re still using an old-school manual dial, you’re missing out on huge energy savings.
✅ Best Temperature Settings for Maximum Efficiency:

❄️ 6. Use Ceiling Fans to Circulate Warm Air
Ceiling fans aren’t just for summer—they can help distribute heat more efficiently.
✅ How to Set Your Fan in Winter:

• Flip the reverse switch so it spins clockwise.
• Set it to low speed—this pushes warm air down instead of letting it collect at the ceiling.

💡 Pro Tip: This works best in rooms with high ceilings where heat tends to rise and stay trapped.

❄️ 7. Avoid Overworking Your Furnace with Space Heaters
Space heaters can be helpful for spot heating, but they aren’t a cost-effective solution for your whole home.
🚫 Why Space Heaters Can Hurt Efficiency:

• They consume tons of electricity (often more than your furnace).
• They create uneven heating, making your thermostat work harder.
• Running multiple units can increase your energy bill instead of lowering it.

✅ Instead, try:

• Adding extra layers & blankets before resorting to space heaters.

• Ensure proper airflow: Keep at least 18 inches of clearance around the unit.
• Check the defrost cycle: If the pump doesn’t automatically defrost, consult a professional.

Heat pumps are designed to handle cold weather, but extreme ice buildup may indicate a problem.

8. Carbon Monoxide ConcernsTroubleshooting Steps:

• Install CO detectors: Place detectors near bedrooms and furnace areas.
• Check ventilation: Ensure your furnace exhaust vent is clear of snow or debris.
• Schedule annual inspections: A professional can identify potential leaks in your system.

Carbon monoxide is a silent danger, so always prioritize safety.

When to Call a ProfessionalWhile some issues are easy to resolve, others may require professional expertise. Contact an HVAC technician if:

• Your furnace doesn’t respond after basic troubleshooting.
• You notice unusual smells, such as burning or gas odors.
• The problem recurs frequently, even after repairs.

Minnesota winters demand a reliable HVAC system, and understanding basic troubleshooting can keep your home warm and safe. By addressing small issues early, you can avoid costly repairs and enjoy a cozy winter season. For persistent problems, don’t hesitate to reach out to an HVAC professional.

Best Practices for Heating Empty Spaces in Winter
Minnesota winters can be brutal, and homeowners often wonder how to handle heating unoccupied spaces like guest rooms, basements, or rarely used areas. While it’s tempting to completely close off these spaces to save energy, doing so can lead to issues like frozen pipes, structural damage, or uneven heating in your home. Here are some best practices for heating empty spaces efficiently and effectively during the winter.

1. Don’t Completely Shut Off Heating
While you may not need to keep empty spaces as warm as the rest of your home, completely shutting off heating to these areas can create problems like:

• Frozen pipes in areas with plumbing.
• Condensation and mold growth from trapped moisture.
• Uneven heating, which forces your HVAC system to work harder.

Set the thermostat in these spaces to a lower, but still safe, temperature—around 55°F to 60°F is ideal.

2. Use Zone Heating
Zone heating allows you to heat specific areas of your home without wasting energy on unused spaces. If your HVAC system has zoning capabilities:

• Program it to maintain lower temperatures in empty rooms.
• Use smart thermostats to control individual zones efficiently.

For homes without a zoned system, consider space heaters for targeted heating (used safely and sparingly).

3. Seal and Insulate Empty Spaces
Proper insulation ensures that even unused areas stay warm enough without requiring extra energy.

• Seal windows and doors with weatherstripping or caulk to prevent drafts.
• Add insulation to attics, crawl spaces, and walls where heat may escape.
• Close vents in rooms you’re not actively using, but avoid sealing them entirely as it can strain your HVAC system.

4. Keep Interior Doors Open
Leaving doors open to empty spaces helps circulate warm air throughout your home. This minimizes temperature disparities and reduces the risk of cold spots that can lead to issues like condensation or freezing.

5. Use Ceiling Fans to Circulate Heat
Ceiling fans aren’t just for summer—they can help circulate warm air in winter too. Set the fan to rotate clockwise at a low speed to push warm air from the ceiling down into the room, even in unused areas.

6. Monitor Humidity Levels
Empty spaces can become overly dry or humid in winter, leading to potential structural problems.

• Use a humidifier to maintain a balanced humidity level between 30-50%.
• If the area feels damp, use a dehumidifier to prevent mold or mildew growth.

7. Protect Plumbing in Unused Areas
If your empty space contains plumbing, it’s especially important to maintain adequate heating to prevent frozen pipes. Additional tips:

• Let faucets drip slightly to keep water moving.
• Open cabinet doors under sinks to allow warm air to reach pipes.
• Insulate exposed pipes for extra protection.

8. Use Rugs or Carpets for Extra Insulation
If you have hardwood or tile floors in unused areas, consider adding rugs or carpets. These can help insulate the space, retain heat, and make it more comfortable if you need to use the room.

9. Check for Air Leaks Regularly
Even if a space is unoccupied, air leaks can increase heating demands. Regularly inspect for drafts around windows, doors, and exterior walls in these areas, and address them promptly.

10. Schedule Regular HVAC Maintenance
​Keeping your heating system in peak condition ensures it operates efficiently, even when heating unused spaces. Regular maintenance includes:

• Inspecting ductwork for leaks.
• Cleaning and replacing air filters.
• Testing thermostats and zone controls.

Why Heating Empty Spaces Matters
Heating empty spaces may seem unnecessary, but it protects your home’s structure, prevents costly damage, and ensures your HVAC system operates efficiently. By following these best practices, you can maintain a safe, comfortable home while keeping energy costs in check.
