December in Dallas means longer nights and cooler temperatures, which leads to increased use of heating systems. For many homeowners, this is the first month of continuous heating after months of AC use. Without proper preparation, HVAC systems can work inefficiently, resulting in energy spikes and higher utility bills. Factors like duct leaks, uneven airflow, thermostat settings, and residual summer inefficiencies can all contribute to unnecessary energy consumption.
Fortunately, there are steps homeowners can take to maintain comfort while controlling energy costs and reduce strain on their HVAC system during December.
Tips to Improve HVAC Efficiency in December
Inspect and Seal Ductwork:
Leaky ducts are a major source of wasted energy. Even small gaps in joints or connections can let warm air escape into attics, crawlspaces, or walls. Sealing ducts with foil tape or mastic improves heat delivery, reduces energy consumption, and ensures that every room in your home stays warm.
Balance Airflow Between Rooms:
Uneven heating can make some areas of the home uncomfortable while causing the HVAC system to overwork. Adjusting dampers or rearranging furniture that blocks vents can help distribute heat evenly. Rooms with high ceilings or large windows may need special attention to maintain consistent warmth.
Tune Up Your HVAC System:
Routine maintenance, including cleaning coils, lubricating motors, inspecting belts, and checking refrigerant levels, ensures your system is running efficiently. An optimized system consumes less energy while providing more consistent heating throughout your home.
Optimize Thermostat Settings:
Programmable thermostats allow you to adjust heating schedules according to occupancy. For example, lower the temperature overnight or when the home is empty during the day, and raise it gradually before returning home. This reduces unnecessary heating and prevents sudden energy spikes.
Check for Residual Summer Inefficiencies:
If your AC struggled during the summer or left dust, dirt, or debris in your system, these issues can carry over into the heating season. Clogged filters or dirty coils force the system to work harder, consuming more energy. Ensure summer maintenance issues are addressed before fully switching to heating mode.
Local Insight
Older North Dallas homes with tile or hardwood floors tend to lose heat faster than carpeted areas, often requiring more energy to maintain comfort. Modern homes in areas like Uptown or Lake Highlands may have tightly sealed ductwork but can experience microclimates where certain rooms overheat while others remain cooler. Homes near wooded or shaded areas, such as White Rock Lake, may require additional duct inspections to ensure airflow isn’t obstructed by leaves or debris. Local HVAC professionals understand these neighborhood-specific factors and can tailor solutions accordingly.
Additional Tips for Homeowners
- Use ceiling fans on low to circulate warm air efficiently.
- Close vents in unused rooms to focus heating where it’s needed.
- Keep curtains or blinds closed at night to reduce heat loss through windows.
