Monthly Checklist (Do These First)

• HVAC filter: Replace or clean.

• Sinks, tubs, showers: Clear slow drains (enzyme or mechanical).

• Kitchen & bath caulk: Spot cracks, re-caulk tiny gaps.

• Range hood filters: Degrease in hot soapy water.

• Garbage disposal: Ice + baking soda/vinegar refresh.

• Toilets: Dye-tablet leak test; adjust flapper if needed.

• Fire safety: Test smoke/CO alarms.

• Exterior walk-around: Look for peeling paint, soft wood, standing water.

• Door hardware: Lube hinges/locks; tighten loose screws.

• Humid areas: Run dehumidifier to keep 40–50% RH (mold prevention).

Time: 60–90 min total • Typical cost: <$20

Quarterly (Every 3 Months)

• GFCI/AFCI test: Press “TEST/RESET.”

• Dryer duct: Vacuum accessible duct; verify exterior flap opens freely.

• Plumbing scan: Under sinks & around toilets for seepage.

• Softener or filter systems: Top up salt / change cartridges.

• Door/window weatherstripping: Replace worn sections.

• Garage safety: Test auto-reverse on door; inspect springs/cables (visual only).

• Pest prevention: Inspect attic/crawlspace; add door sweeps if gaps.

Time: ~2–3 hrs • Cost: $10–$60 (DIY)

Seasonal Checklists

Spring (Post-Thaw & Pollen)

• Gutters & downspouts: Clean; extend to discharge 5–10 ft from foundation.

• Roof: Check shingles, flashing, soft spots; schedule repair before storm season.

• Exterior sealing: Caulk trim/penetrations; repaint bare wood.

• HVAC (cooling): Replace filter; clear vegetation 2–3 ft around condenser; hose fins.

• Sump pump: Test with a bucket; check backup power.

• Irrigation: Open valves, check leaks, adjust heads off siding.

• Deck/patio: Clean; reseal if water no longer beads.

Time: 1 day DIY • Cost: $50–$300 (materials); roof work → pro.

Summer (Heat & Humidity)

• Attic & insulation: Verify vents are clear; look for hot-spot moisture.

• AC performance check: Supply vs. return temp (ΔT ≈ 16–22°F / 9–12°C).

• Exterior grade: Soil slopes away from house 1″ per foot (first 6–10 ft).

• Windows/doors: Confirm smooth operation; add UV film or shades where needed.

• Grill & outdoor faucets: Inspect hoses; check for gas leaks (soapy water).

• Mold patrol: Keep indoor RH 40–50%; wipe AC condensate pan/algae tabs if allowed.

Fall (Prep for Freeze & Storms)

• Gutters: Final clean after leaves fall; install guards if chronic.

• Heating tune-up: New filter; vacuum registers/returns; bleed radiators if hydronic.

• Weatherproofing: Install storm windows; replace door sweeps.

• Outdoor plumbing: Blow out sprinklers; shut & drain hose bibs.

• Chimney & fireplace: Sweep/inspect (wood-burning).

• Generator: Test under load; fuel stabilized; cords labeled.

• Snow gear: Service snowblower; stock ice melt (pet-safe if needed).

Winter (Freeze, Wind, Low Sun)

• Ice dam prevention: Rake roof edges after heavy snow; keep attic cold & ventilated.

• Interior humidity: Don’t exceed ~40% at ≤32°F (0°C) outside; use bath/kitchen fans.

• Condensate drains: Ensure high-efficiency furnace/boiler drains are unfrozen.

• Vacuum fridge coils (if not done earlier); check gaskets with paper-slip test.

• Test CO/smoke alarms during heating season; replace units >10 years old.

• Walkways: Keep clear; treat slippery surfaces.

Annual & Biannual Deep Maintenance

Once a Year

• Water heater: Flush sediment (tank); descale tankless.

• Roof pro inspection: Drones or binoculars + targeted repairs.

• Foundation & crawlspace: Check for cracks, efflorescence, pests.

• Electrical panel: Tighten lugs (pro), label circuits clearly.

• Windows: Wash, inspect glazing/paint; re-caulk perimeter.

• Exterior paint: Touch-ups; full repaint ~5–10 yrs (climate dependent).

• Driveway: Seal asphalt; repair concrete cracks.

• Appliances: Pull out fridge/range; clean behind, verify hoses (stainless braided).

• Termite/wood-destroyer inspection (risk zones).

• Septic: Inspect; pump 2–5 yrs depending on usage.

Every 6 Months

• Dryer vent deep clean: Brush kit through entire run.

• Fridge water filter (if fitted).

• Whole-home water filter/RO: Replace cartridges.

• Test safety devices: All alarms, fire extinguishers (gauge in green).

Safety & Emergency Readiness (15-Minute Setup That Matters)

• Main water, gas, and electrical shutoffs: Tag and teach all occupants.

• Photo inventory of valuables (cloud backup).

• Go-bag: Copies of IDs, meds, cash, chargers, basic tools, pet needs.

• Disaster plan: Evac routes; out-of-area contact; meet points.

• Fire extinguishers: One per floor + kitchen/garage; know PASS method.

Tools & Supplies

Minimal Starter Kit (under $150)

• 6-in-1 screwdriver, adjustable wrench, pliers set

• Utility knife, tape measure, stud finder

• Caulk gun + exterior/paintable caulk

• Plumber’s tape (PTFE), plungers (cup & flange), enzyme drain cleaner

• Ladder (6–8 ft), work gloves, N95 masks

• Voltage tester, outlet tester, flashlight/headlamp

Pro-Tier Add-Ons (when you’re ready)

• Wet/dry vac, pressure washer (with care), rotary dryer-vent brush

• Thermal camera or IR thermometer

• Dehumidifier with built-in humidistat

• Gutter cleaning kit, inspection camera for drains

• Smart leak detectors (laundry, water heater, sinks)

If You Rent, Have an HOA, or Just Moved In

Renters: Do monthly items + leak checks; report roof/structural/HVAC issues to the landlord with dated photos.
Condo/HOA: Your responsibility usually includes interior, windows from the paint-inward, and appliance upkeep—confirm bylaws for exterior/roof.
New Homeowners (First 30 Days):

• Label the panel; map each breaker.

• Replace unknown-age alarms/filters.

• Photograph every room & system; note serial numbers.

• Schedule first roof/gutter and HVAC maintenance.

Troubleshooting: Fix These First (Order of Urgency)

1. Active leak or moisture (ceiling stains, wet carpet, musty odor) → Stop water, dry within 24–48h to prevent mold.

2. Electrical burning smell, hot outlets, frequent tripping → Shut off power to circuit; call a licensed electrician.

3. Gas odor/CO alarm → Evacuate; call utility/911.

4. Foundation movement (new cracks >1/4″, doors suddenly stick) → Document & get a structural assessment.

5. HVAC failure in extreme weather → Protect pipes from freezing; use space heating/cooling safely until serviced.

FAQ 

Q1: What should I do every month?
Change the HVAC filter, test alarms, clean range hood filter, scan for leaks, and do a quick exterior walk-around.

Q2: How often should gutters be cleaned?
At least twice a year—after spring pollen and after leaves fall. More often under heavy trees.

Q3: When do I replace smoke/CO detectors?
Test monthly, replace batteries yearly, and replace units every 10 years (5–7 for some CO models).

Q4: Tank vs. tankless water heater maintenance?
Tank: flush sediment annually. Tankless: descale annually (more in hard-water areas).

Q5: What if I can’t do ladder work?
Use pro services for roof/gutter/chimney. It’s cheaper than a fall or a roof leak.
