Top Signs You're Overworking Your Heating System (And How to Fix It!)

01/08/2025

Winter is the snuggly season we look forward to for cozy blankets and warm beverages. However, the downside can be the challenge of higher heating bills. The reasons can vary, but it’s usually because your heater is being used more, and more usage oftentimes equals a higher bill.

The good news is that there are plenty of effective ways to keep your home warm without overburdening your heater, helping you save both energy and money in the process.

In this guide, we’ll share seven common habits that tend to strain heaters when it’s cold out, provide practical tips on how to avoid those habits, and share helpful methods to heat your home more efficiently and cost-effectively.

1. Forgetting to “Turn It Low Before You Go”

One of the most helpful ways to cut down on heating costs and energy use is to turn down the thermostat when you're not home. Many people leave the heater running at the same temperature all day, unnecessarily using energy while they’re out. Small temperature adjustments could help lead to substantial savings over the winter months. With a programmable thermostat, you can automate these settings to ensure your home is comfortable when needed and energy-efficient at all other times.

Use a programmable thermostat to set schedules for your heating system. For instance:

• Lower the temperature to around 62°F–65°F while you're out or sleeping (health allowing).
• Program it to gradually return to a comfortable 68°F–70°F shortly before you arrive home or wake up.

According to the U.S. Department of Energy, turning your thermostat back 7°-10°F for eight hours a day can save you up to 10% annually on heating costs.

2. Letting Cold Air Sneak Inside

Drafty windows and doors are major contributors when it comes to heat loss. Even a small gap can cause your heater to work overtime to maintain the desired indoor temperature. Luckily, these leaky spaces can be fixed easily.

Solution:

Weather-Stripping for Doors: Apply weather-stripping to door frames to block drafts and prevent heat from escaping.

Caulk for Window Gaps: Use caulking to seal cracks and gaps around windows, ensuring a tighter seal against cold air. Closing these gaps isn’t just about reducing drafts—it helps prevent your heater from over-compensating for exterior temperatures, which could help lower your bill.

3. Overlooking the Importance of Insulation

Proper insulation is key in keeping warm air in and cold air out, especially during the winter months. Homes without adequate insulation can lose significant amounts of heat.

Solution:

• Attic and Wall Insulation: Ensure your attic and walls are properly insulated to retain indoor warmth effectively.
• Thermal Curtains for Windows: If you have large windows, consider adding thermal curtains as an extra barrier against heat loss.
• Pipe Insulation: Don’t forget to insulate pipes to prevent heat loss and protect them from freezing.

By adding the right insulation, you’ll help enhance your home’s energy efficiency, reduce heat loss, and keep your household more comfortable—all while aiding in lowering your utility bills.

4. Cranking Up the Thermostat Too High, Too Fast

It’s tempting to turn up the thermostat several degrees when you walk in from the cold, hoping to warm your home quickly. However, this doesn’t heat your home any faster and can actually overwork your heating system. Forced-air heating systems work at a consistent rate regardless of how high you set the thermostat, meaning the extra heat setting only adds unnecessary strain on your system over time.

Solution:

• Set a Gradual and Comfortable Temperature: Instead of cranking up the heat, set your thermostat to a reasonable temperature, like 68°F, health allowing, and wait for your home to warm up at its natural pace. This not only protects your heating system but also avoids wasting energy.
• Use Ceiling Fans: Set your ceiling fan to spin clockwise. This helps bring heated air down towards you in rooms with higher or sloped ceilings.
• Use the Sun: Take advantage of the free warmth provided by the sun. Open your curtains during the day to allow natural sunlight to heat your home. Remember to close them at night to retain the heat.
• Close Off Unused Rooms: Keep doors to unused rooms shut to focus heating on the areas where it’s most needed.

By avoiding the habit of cranking up the thermostat and using these practical tips, you can achieve a warm, comfortable home while helping to save energy and protecting your heating system from unnecessary strain.

5. Blocking Vents & Registers with Furniture or Curtains

To make the most of your heating system, make sure that your heaters and vents aren't obstructed by furniture, curtains, or other household items. Blocked vents hinder the proper distribution of warm air, leading to uneven heating and cold spots throughout your home. This not only makes rooms less comfortable but also forces your heating system to work harder, consuming more energy and potentially driving up your energy bills. Keep these areas clear to allow for consistent warmth and to reduce unnecessary work on your system.

Solution:

• Check the vents in your home to ensure they are clear of obstructions.
• Place furniture at least a few inches away from vents to allow airflow.
• Use vent extenders to redirect air under furniture pieces.

This small adjustment can help keep your home warm without increasing your energy usage.

6. Ignoring Routine Maintenance

Out of sight, out of mind. Heating systems or HVAC units often sit in basements, attics, or in the corner of your yard, making it easy to forget about vital maintenance tasks and upkeep. Regular inspections by a licensed professional can identify potential issues before they become major (and expensive) problems.

Another important task you can do at home is to regularly replace air filters. This aids in keeping your heating system at peak performance, as well as helping reduce allergens and dust, improving indoor air quality.

Solution:

• Schedule Annual Inspections: Have a licensed HVAC professional check your system for wear and tear, inspect components, and clean ducts.
• Replace Filters Regularly: Clean air filters ensure efficient airflow. Replace filters every 1-3 months, especially during peak winter usage.

7. Failing to Identify When It’s Time for a Replacement

Recognizing when your heating system has reached the end of its lifespan is crucial. Overlooking the signs of an aging or inefficient system can lead to higher energy bills, inconsistent heating, and unexpected breakdowns. Paying attention to warning signs such as frequent repairs, strange noises, or an inability to maintain a comfortable temperature can help you determine when it’s time to invest in a new, more efficient system.
