Late winter can be tricky for homeowners. Temperatures still dip low enough to demand reliable heat, yet fluctuating weather can expose comfort issues and inefficiencies that went unnoticed earlier in the season. Making a few smart adjustments now—and scheduling professional furnace maintenance in Washington, DC—can help you stay warm, reduce energy waste, and avoid surprises before spring arrives.
Keep Supply and Return Vents Clear
One of the simplest ways to improve comfort is also one of the most overlooked. Furniture, rugs, curtains, or décor blocking vents can disrupt airflow, forcing your furnace to work harder while certain rooms feel chilly. Walk through your home and make sure all supply and return vents are open and unobstructed. Proper airflow allows heat to distribute evenly and helps your system operate as designed.
Change Your Air Filter Monthly
During heavy heating use, air filters can clog quickly with dust, pet dander, and debris. A dirty filter restricts airflow, strains your furnace, and can even trigger shutdowns in some systems. Replacing the filter every month in late winter supports better airflow, healthier indoor air, and improved efficiency. If you’re unsure which filter type is right for your system, our team can help guide you.
Use Your Thermostat Strategically
Your thermostat plays a major role in both comfort and energy costs. If you have a programmable or smart thermostat, take a few minutes to review the schedule. Lower temperatures slightly while you’re asleep or away, then set it to warm up before you return. Avoid drastic temperature swings, which can cause your furnace to run longer than necessary and reduce efficiency.
Set Ceiling Fans to Winter Mode
Ceiling fans aren’t just for summer. In winter, they should spin clockwise at a low speed to gently push warm air down from the ceiling and back into the living space. This simple adjustment can make rooms feel warmer without increasing the thermostat setting, especially in rooms with high ceilings.
Maximize Passive Solar Heat
Take advantage of free heat from the sun. Open curtains and blinds on south-facing windows during the day to let sunlight naturally warm your home. As evening approaches, close them to reduce heat loss through the glass. This balance can noticeably improve comfort without adding to your heating bill.
