What To Know
- This is because it can prevent the temperature from dropping too much when the furnace isn’t running, reducing the amount of time the furnace has to work to reach the desired temperature.
- If your home has a large open floor plan, you may not need to run the fan as often as someone with a multi-level home.
- If you have young children or elderly individuals in the home, you may want to run the fan less often to avoid overheating.
The winter chill is upon us, and everyone is looking for ways to stay warm and comfortable. But should you keep your furnace fan running constantly throughout the winter? The answer isn‘t as simple as a yes or no. Let’s explore the pros and cons of running your furnace fan continuously, helping you make the best decision for your home and your wallet.
The Pros of Running Your Furnace Fan Continuously
- Improved Air Circulation: A running furnace fan circulates air throughout your home, ensuring that warm air reaches every corner. This can help to eliminate cold spots and create a more comfortable living environment, especially if you have a multi-level home.
- Even Temperature Distribution: By constantly circulating air, the fan helps to maintain a more consistent temperature throughout your house. This can be especially beneficial for rooms that tend to get colder or warmer than others.
- Reduced Dust and Allergens: A running fan can help to filter out dust, pollen, and other allergens from the air, creating a healthier indoor environment for everyone.
- Potential for Energy Savings: Some studies suggest that running your furnace fan continuously can actually save you money on your heating bills. This is because it can prevent the temperature from dropping too much when the furnace isn’t running, reducing the amount of time the furnace has to work to reach the desired temperature.
The Cons of Running Your Furnace Fan Continuously
- Increased Energy Consumption: While the potential for energy savings exists, running your furnace fan continuously will consume more energy than running it only when the furnace is on. This increased energy use can lead to higher heating bills.
- Potential for Overheating: If your furnace is already running frequently, running the fan continuously can lead to the house becoming too warm. This can be especially problematic if you have young children or elderly individuals in the home.
- Increased Wear and Tear: Running the fan continuously can put additional strain on your furnace motor, potentially leading to premature wear and tear.
- Noise: A continuously running fan can create a constant hum or whirring sound, which can be annoying or disruptive for some people.
The Best Time to Run Your Furnace Fan
The ideal time to run your furnace fan depends on your individual needs and preferences. Here are a few factors to consider:
- Your Home’s Layout: If your home has a large open floor plan, you may not need to run the fan as often as someone with a multi-level home.
- Your Heating System: The type of furnace you have can also impact how often you need to run the fan. Some furnaces are more efficient than others, meaning they may not need to run as frequently to maintain a comfortable temperature.
- Your Family’s Needs: If you have allergies or asthma, you may want to run the fan more often to improve air quality. If you have young children or elderly individuals in the home, you may want to run the fan less often to avoid overheating.
The “Auto” Setting: Your Best Friend
Most modern furnaces come equipped with an “auto” setting for the fan. This setting allows the fan to run only when the furnace is on, providing the benefits of improved air circulation without the drawbacks of continuous operation. This setting is a great compromise, offering the best of both worlds.
Other Tips for Staying Warm and Saving Money
- Seal Your Home: Air leaks can significantly impact the efficiency of your heating system. Look for drafts around windows, doors, and other openings, and seal them with weather stripping or caulk.
- Insulate Your Home: Proper insulation can help to prevent heat loss, keeping your home warmer and reducing your heating bills.
- Use Curtains and Blinds: Close your curtains and blinds at night to prevent heat loss through your windows.
- Dress Warmly: Layer up with warm clothing to stay comfortable without cranking up the thermostat.
The Verdict: When to Run Your Furnace Fan
Ultimately, the decision of whether to run your furnace fan continuously is a personal one. If you live in a cold climate and want to ensure even temperature distribution throughout your home, running the fan may be beneficial. However, if you are concerned about energy consumption or noise, you may want to stick to the “auto” setting.
The Final Word: Make an Informed Decision
By understanding the pros and cons of running your furnace fan continuously, you can make an informed decision that is right for your home and your family. Remember, a well-maintained furnace and a few simple energy-saving tips can help you stay warm and comfortable all winter long.
