1. Seal Your Ducts
Leaky ductwork wastes 20-30% of your heated air before it reaches the rooms you live in. D&D has found homes in Arlington and Bethesda losing hundreds of dollars per winter from duct leaks alone. Professional sealing pays for itself within one season.
2. Program Your Thermostat (For Real)
Drop to 68°F when home, 62°F when sleeping, 58°F when away. A smart thermostat automates this and can save 10-15% annually. David installs and configures them so you actually use the features.
3. Change Your Filter Monthly in Winter
A clogged filter makes your furnace work harder and use more energy. In the DC Metro area's cold winters, monthly changes keep efficiency high and prevent strain on the blower motor.
4. Check Your Insulation
Many Northern Virginia homes built before 2000 are under-insulated by current standards. Adding attic insulation is one of the highest-ROI improvements — often $1,000-2,000 for a significant comfort and efficiency upgrade.
5. Schedule a Fall Tune-Up
A pre-season tune-up catches issues before the first cold snap. David's team checks efficiency, safety, and performance — and catches the $200 repair before it becomes a $2,000 emergency.
