Boost attic insulation and service the furnace

Heat rises, making the attic one of the largest sources of energy loss in a home. Ensuring adequate attic insulation and an efficiently running furnace are two of the highest-impact winterization steps you can take.

Steps

1. Inspect current insulation: Check your attic insulation depth. If it sits below the tops of the floor joists or appears compressed, damaged, or uneven, you need more.
2. Add insulation to target R-value: Aim for R-38 in temperate climates or R-49 to R-60 in cold climates. Batt or blown-in insulation are both DIY-friendly options.
3. Seal the attic hatch: Insulate and weatherstrip the attic access door to prevent heat from escaping through this often-overlooked gap.
4. Replace furnace filters: Change or clean filters every 1-3 months during heating season. A clogged filter restricts airflow and forces the system to work harder.
5. Schedule a professional tune-up: Have the furnace inspected and serviced annually before winter to ensure safe, efficient operation.

Tips

• Seal any gaps around pipes, wires, and ducts that penetrate the attic floor before adding insulation
• A programmable thermostat paired with a well-maintained furnace can cut heating costs by 10-15%
