Outside the House

Winter is hard on exteriors. Walk the property once with this list—you'll catch small problems before they become expensive ones.

[ ] Clean gutters and downspouts — Clear leaves and check for ice-damage sagging
[ ] Inspect roof shingles — Look for curling, missing, or cracked tabs; binoculars work from the ground
[ ] Power wash siding and deck — Hit mildew before warm humid weather sets in
[ ] Test outdoor faucets — Turn each one on and watch for split pipes from freeze-thaw cycles
[ ] Service the lawn mower — Sharpen the blade, change oil, replace the spark plug before grass needs weekly cuts
[ ] Apply pre-emergent weed control — Timing depends on region: March in the South, April in the North

While you're on the ladder for gutters, glance at chimney flashing and vent caps. Loose seals let water in quietly.

Inside the House

Spring allergy season and summer AC load both start here.

[ ] Replace the HVAC filter — MERV 8–11 balances airflow and pollen capture
[ ] Schedule an AC tune-up — $75–$200 beats a dead unit on a July weekend ($$$)
[ ] Test smoke and CO detectors — Fresh batteries; replace units older than 10 years
[ ] Clean the dryer vent — Lint buildup causes thousands of US house fires every year; pull the duct and vacuum it out
[ ] Check caulk around tubs and windows — Re-caulk gaps before spring rains find them
[ ] Reverse ceiling fans — Counterclockwise for summer cooling once rooms warm up

Trim Energy Bills While You're at It

Wash window screens so you can open windows without inviting pollen indoors (well, less of it). If you still have a manual thermostat, a programmable model pays for itself—ENERGY STAR estimates around $180/year for the average US household.

Seal attic air leaks with spray foam around recessed lights and pipe penetrations. Heat sneaks out through holes you'd never notice until you crawl up there with a flashlight.

Block a Saturday, grab coffee, work top to bottom. By summer you'll be glad you did the boring stuff in spring.
