Staying warm during winter doesn’t have to mean overspending on energy bills. HVAC professionals recommend a strategic approach to thermostat settings, airflow, and consistent adjustments to maximize comfort while minimizing costs. The ideal setup is a balance between personal preference and energy efficiency.
The Sweet Spot for Winter Temperatures
The U.S. Department of Energy suggests 68°F (20°C) as a baseline for winter temperatures during occupied hours. However, many people find this too cold for comfortable, prolonged indoor living. Keith Wortsmith, president of DASH Heating & Cooling, notes that 70°F (21°C) is often a more practical setting for those who prefer to stay cozy without bundling up excessively.
While 68°F is efficient, it’s only effective if you move around and wear layers. If you’re prone to feeling cold, slightly raising the temperature within reason can make a substantial difference without drastically increasing costs. HVAC pros advise against exceeding 72°F (22°C), as heating expenses can jump by 1–3% for each degree above that threshold.
The Role of Airflow, Insulation, and Humidity
Temperature perception isn’t just about the thermostat. Alyssa Rogers, owner of Rogers Heating & Cooling, emphasizes that airflow, insulation quality, and indoor humidity significantly affect how warm a home feels. A well-maintained system at 68°F can be warmer than a poorly performing system set higher. Ensuring your home is adequately insulated and humidity is balanced will make a big difference.
Nighttime Savings: Lowering the Thermostat Strategically
Lowering the thermostat when you’re asleep or away can yield savings, but consistency is key. Nick Barber, cofounder at Prepaid Electricity, suggests reducing the temperature by 7–10 degrees Fahrenheit (4–5.5 degrees Celsius) for eight hours daily to save up to 10% on heating bills annually.
Avoid frequent, large temperature swings, as these can force your heating system to work harder than maintaining a steady, reasonable setting. Gradual changes are more efficient than dramatic adjustments.
The Fan Setting: Auto vs. On
Your thermostat’s fan setting can also impact comfort. HVAC experts recommend setting the fan to “AUTO” rather than “ON.” In “AUTO” mode, the fan runs only during heating cycles, preventing cool air from lingering in ducts when the furnace is off. Leaving the fan on “ON” continuously circulates air, making rooms feel drafty even when the heating system isn’t actively warming them.
Beyond the Thermostat: Additional Tips
Here are some extra tricks for staying warm without turning up the thermostat:
- Wear layers of clothing.
- Seal drafts around windows and doors.
- Use rugs to insulate floors.
The key to winter comfort and savings is a balanced approach. Adjusting your thermostat strategically, optimizing airflow, and maintaining consistency will help you stay warm without breaking the bank.
