How do I prepare my home for winter?
Service your HVAC, insulate exposed pipes, clean gutters, seal drafts, reverse ceiling fans, and stock emergency supplies before the first freeze.
Heating + insulation
Schedule HVAC tune-up ($85–$200). Replace furnace filter. Add attic insulation if R-value below 38. Seal air leaks at doors and windows. Reverse ceiling fans clockwise to push warm air down.
Plumbing
Insulate exposed pipes in unheated spaces. Disconnect outdoor hoses and shut off exterior valves. Drain irrigation systems. Know where your main shut-off is.
Exterior
Clean gutters thoroughly. Trim tree branches over the roof. Inspect roof for missing shingles. Stock rock salt and snow shovels. Service snow blower.
Emergency prep
Test smoke and CO detectors. Stock 3-day water and food. Have flashlights, batteries, blankets, and a backup heat plan ready.
