Your home is likely your biggest investment—and like any investment, it needs regular care to stay in top shape. Neglecting routine maintenance can lead to costly repairs down the road, but keeping up with small monthly tasks can help you avoid major headaches. A simple, consistent monthly home maintenance checklist ensures your home stays safe, efficient, and comfortable all year long.
1. Inspect and Change HVAC Filters
Your heating, ventilation, and air conditioning (HVAC) system works hard to keep your home comfortable. Dirty air filters can reduce its efficiency and increase energy bills.
To Do:
- Check HVAC filters every month
- Replace if dirty or clogged (usually every 1–3 months)
Tip: Clean filters improve air quality and help prevent system breakdowns.
2. Test Smoke and Carbon Monoxide Detectors
Smoke and CO detectors are vital for your safety, but only if they’re functioning properly. A quick monthly test ensures they’re ready when needed.
To Do:
- Press the test button on each detector
- Replace batteries if they don’t respond or chirp
Bonus Tip: Clean the detectors with a vacuum to remove dust buildup.
3. Check for Leaks
Water damage can cause serious and expensive problems, so it’s important to catch leaks early.
To Do:
- Inspect under sinks, around toilets, and behind appliances
- Look for water stains, puddles, or signs of mold
Pro Tip: Monitor your water bill—an unexpected spike could indicate a hidden leak.
4. Clean Kitchen Exhaust Hood and Filters
Your kitchen exhaust hood removes grease, smoke, and odors from cooking, but its filters can get dirty quickly.
To Do:
- Remove and wash filters in warm, soapy water
- Wipe down the hood and fan components
Why It Matters: Clean filters prevent fire hazards and keep your kitchen air fresh.
5. Run Water in Unused Drains
Unused bathrooms or sinks can dry out, causing sewer gas to seep into your home.
To Do:
- Run water for a few seconds in guest bathrooms or unused sinks
- Pour a cup of water into floor drains
Tip: Add a little vinegar or baking soda to keep drains smelling fresh.
6. Check Exterior Vents and Intakes
Blocked vents can reduce airflow and affect appliance efficiency—or worse, become a fire risk.
To Do:
- Clear lint from dryer vents
- Remove leaves or debris from HVAC or furnace intake vents
Extra Step: Look for signs of animals or pests nesting near these areas.
7. Inspect and Touch Up Caulking
Caulk helps seal out moisture and drafts, especially around tubs, sinks, windows, and doors.
To Do:
- Check for cracks, peeling, or gaps in caulking
- Reapply as needed to prevent water intrusion and heat loss
8. Deep Clean Key Areas
A little deep cleaning each month helps prevent buildup that can be tough to tackle later.
Focus Areas:
- Baseboards and ceiling fans
- Light fixtures
- Inside the fridge and pantry
- Washing machine and dishwasher seals
9. Test Garage Door Safety
Garage doors can become dangerous if the auto-reverse mechanism stops working.
To Do:
- Place a block of wood under the door and close it
- If it doesn’t reverse automatically, schedule a service check
Maintenance Tip: Lubricate the moving parts to keep the door running smoothly.
10. Walk Around the Exterior
Take a quick monthly stroll around your home to catch early signs of trouble.
To Check:
- Roof and gutters for visible damage or debris
- Foundation for cracks
- Outdoor faucets for leaks
- Siding and paint condition
