The homeowner’s simple efficiency checklist

Small maintenance habits and bigger upgrades worth evaluating.

Look for air leaks

Inspect weatherstripping around doors and windows. Seal obvious leaks where appropriate and safely.

Maintain HVAC equipment

Follow manufacturer guidance for filters and servicing. Review equipment sizing and duct conditions before replacement.

Prioritize insulation

Attics and other areas can be significant sources of heating and cooling loss. Evaluate insulation alongside ventilation and moisture management.

Check window condition

Assess drafts, failed seals, water intrusion, and frame deterioration before deciding whether repair or replacement is appropriate.

Review energy usage

Compare utility bills across seasons and identify any major shifts in household use or appliances.

Get written, itemized estimates

For major work, compare licensed contractors, scope, warranties, timelines, and total installed price.
