Avoid Mistakes That Make Your Heating Control Less Efficient
Avoid Mistakes That Make Your Heating Control Less Efficient
A comfortable and energy‑efficient home isn’t just about having a good furnace or heat pump—it’s also about how you manage your heating system. Even small mistakes in how you set or use your controls can lead to higher energy bills and uneven comfort. Here’s a look at some of the most common errors American homeowners make, and how to fix them.
1. Setting the Thermostat Too High
Many people turn the thermostat way up, thinking it will heat the house faster. It doesn’t. The thermostat only controls the final temperature, not the speed of heating. The result is often an overheated home and wasted energy.
What to do instead: Set your thermostat to the temperature you actually want—around 68°F when you’re home is a good starting point—and let the system do its job. If it feels like your home takes too long to warm up, check for blocked vents, dirty filters, or poor insulation rather than cranking up the heat.
2. Ignoring Programmable or Smart Settings
Modern thermostats often include scheduling or smart features that automatically lower the temperature when you’re asleep or away. If you’re not using these functions, you’re missing out on easy savings.
What to do instead: Program your thermostat to drop the temperature by 7–10°F for eight hours a day—typically overnight or while you’re at work. According to the U.S. Department of Energy, this can save up to 10% a year on heating costs.

3. Poor Thermostat Placement
Your thermostat measures the temperature where it’s installed. If it’s near a drafty window, a heat vent, or in direct sunlight, it will get inaccurate readings and cause your system to run inefficiently.
What to do instead: Place the thermostat on an interior wall, about five feet above the floor, away from direct sunlight, drafts, and heat sources. This ensures it senses the true average temperature of your living space.
4. Skipping Regular Maintenance
Even the best heating system needs periodic care. Dusty filters, clogged vents, or a neglected furnace can make your system work harder and waste energy.
What to do instead: Replace or clean filters every one to three months during the heating season. Have a professional HVAC technician inspect your system annually to check for leaks, worn parts, and efficiency issues.
5. Closing Too Many Vents or Registers
It might seem logical to close vents in unused rooms to save energy, but doing so can upset the balance of your system, increase pressure in the ducts, and reduce overall efficiency.
What to do instead: Keep most vents open and unobstructed. If you want to reduce heating in certain rooms, consider zoning systems or smart vents designed for that purpose.
6. Setting the Temperature Too Low for Heat Pumps
If you use a heat pump, setting the thermostat too low can cause the system to rely on its backup electric resistance heat, which is far less efficient.
What to do instead: Keep your thermostat at a steady, moderate temperature. Avoid large temperature swings, and use the “heat pump” or “auto” mode recommended by the manufacturer.
7. Forgetting About Insulation and Air Leaks
Even the most advanced heating control can’t compensate for a drafty home. Poor insulation and air leaks make your system run longer and harder.
What to do instead: Seal gaps around windows, doors, and ducts, and add insulation where needed—especially in attics and basements. This helps your heating system maintain comfort with less effort.
8. Using Outdated Controls
Older thermostats may lack features that improve comfort and efficiency, such as learning algorithms, remote access, or energy‑use tracking.
What to do instead: Consider upgrading to a modern smart thermostat. Many models qualify for utility rebates and can pay for themselves through energy savings within a few years.
Small Adjustments, Big Results
Improving your heating efficiency doesn’t always require major upgrades. By avoiding these common mistakes and using your controls wisely, you can enjoy a more comfortable home, lower energy bills, and a smaller environmental footprint—all with just a few thoughtful adjustments.
