Homeowners: Are You Guilty of These 10 Common Furnace Mistakes?

Maintaining your home’s systems is a crucial aspect of homeownership, particularly when it comes to your furnace. Improper use or neglect can lead to safety hazards, increased risk of fires, elevated utility bills, unexpected repairs, inefficient heating, shortened lifespan, or even complete furnace failure. To help you keep your home safe, cozy, and warm throughout the winter, here are ten common furnace mistakes homeowners often make and how to avoid them.

Neglecting Filter Changes

Before your furnace can heat your home, the warm air must pass through a filter. This filter removes dust and other contaminants, improving air quality and keeping your home cleaner. Over time, filters can become clogged, reducing efficiency and causing your furnace to work harder, resulting in higher utility bills and premature wear and tear. To avoid these issues, use manufacturer-recommended filters and replace them on schedule. During harsh winters, consider changing the filter more frequently to ensure efficient operation.

Skipping Annual Maintenance

Even a well-functioning furnace benefits from an annual maintenance checkup by a qualified professional. This service not only improves efficiency through cleaning and adjustments but also helps identify and address potential problems before they lead to equipment failures during the heating season.

Setting the Thermostat Too High

Setting your thermostat too high forces your furnace to run continuously to reach the desired temperature. Instead, maintain a moderate setting and explore ways to improve your home’s efficiency, such as adding insulation, using insulated draperies, and having a professional assess whether your furnace is appropriately sized and operating efficiently.

Delaying Upgrades or Replacements

Postponing furnace upgrades or replacements is not a cost-effective strategy. Older furnaces (15 years or older) operate less efficiently, leading to higher utility bills. Replacing an aging system before it fails or causes a significant increase in costs can provide better value and efficiency for your home.

Choosing a New Furnace Based Solely on Cost

When selecting a new furnace, cost should not be the only consideration. A high-quality, efficient furnace may have a higher upfront cost but will save you money over its lifespan through lower utility and maintenance expenses.

Ignoring Thermostat Adjustments When Away

Homeowners can achieve substantial savings by installing a programmable thermostat and setting it according to their schedule. Lowering the temperature when the home is empty or during nighttime can reduce utility bills and extend the life of your furnace. Consult a professional to select and install the best thermostat for your system.

Allowing Clutter Around Furnace Components

Furnaces often reside in basements, attics, or closets, where clutter can accumulate. This not only creates a fire hazard but also obstructs airflow, reducing efficiency and shortening the furnace’s lifespan. Regularly clear away clutter and clean the area around your furnace during filter changes.

Ignoring Warning Signs

Many homeowners become accustomed to their furnace’s operation and may ignore unusual sounds, odors, or visual signs that something is wrong. Contact a professional immediately if you notice any of these warning signs. Early detection can prevent costly repairs and emergency breakdowns.

Failing to Keep Components Clean

Just like other household appliances, your furnace operates more safely and efficiently when kept clean. Accumulated dust and contaminants can reduce efficiency and pose fire risks. Use a shop vacuum or a soft, clean cloth to maintain clean furnace components.

Not Following Manufacturer’s Instructions

Failing to follow the manufacturer’s instructions for use, care, and maintenance is a common mistake. Different models, sizes, and fuel types have specific requirements for optimal performance and longevity. Follow the manufacturer’s guidelines carefully to maximize your furnace’s efficiency and lifespan.
