Most home maintenance checklists are generic. This one focuses on the tasks that actually prevent expensive winter repairs.
Outside the house
Clean gutters, check the roof for loose shingles, seal gaps around windows and doors, and drain outdoor faucets before the first freeze.
Heating system
Replace furnace filters, schedule a professional inspection, and test every smoke and carbon monoxide detector.
Inside the house
Reverse ceiling fan direction, check for drafts around outlets, and inspect the attic for adequate insulation.
None of these take more than 20 minutes individually — spread across two weekends, they prevent the calls that cost real money in January.
