Annual Home Maintenance Checklist (The Overlooked Systems Most Homeowners Forget)

A practical annual home maintenance checklist focused on the “out of sight, out of mind” systems—dryer vents, shutoff valves, sump pumps, water pressure, radon testing, septic schedules, and more—plus quick ways to test.

TL;DR

Plan one annual “check-ups” day for these systems: safety devices; where the water shutoffs are located; moisture control; ventilation; electrical protection; and especially, the appliances that have started fires (looking at you, dryer vent!).

Most likely items to forget:

• Testing/replacing smoke alarms
• Cleaning the dryer lint paths and vents
• Checking sump/ejector pumps
• Monitoring water pressure/PRV
• Clearing A/C condensate drains
• GFCIs/AFCIs testing
• Confirming radon levels
• Drawing a sketch of where the shutoff is

Keep a simple log: dates, clicks, model numbers, filter sizes, and who you called will avoid repeats and speed up any warranty, or insurance claims.

What to Do On Audit Day

Work it like a preventative doctor visit for that specific area. You’re capping when that’s done! Put the bigger items on a work order of their own, spread out a few days from each other so they aren’t overwhelming.

Pick your repeatable date ahead of time. Is there a safe weekend near your birthday/tax time/when you replace smoke alarm batteries (if you use replaceable batteries)? Work room by room but think “system” by “system”.

Fire, water, air, electricity, structure.

As you go through, take photos of shutoffs, pictures of the size of your filters etc, breaker labels, some “before and after maintenance proof”, “for things that might be too big for us to forget, otherwise. – Create one “Home Maintenance” note: paint colors, appliance model numbers, and the last service date for each system.

Before You Dive In: The 10-Minute Setup

1. Gather tools: flashlight/headlamp, step stool, flathead screwdriver, phone camera, outlet/GFCI tester, small bucket and rags, and a basic water pressure gauge (hose-bibb style).
2. Learn your shutoffs now (before the emergency): the main water shutoff, water heater shutoff, gas shutoff (for gas appliances if applicable), and the electrical main disconnect.
3. Shut off anything you don’t want turning on during your testing, including irrigation timers, any scheduled appliances, or your smart thermostat that could start HVAC equipment.
4. Open up a note on your phone called “Annual Home Audit (insert current year)” and log everything you find as you find it.

1) Fire and Life Safety (Fast and Small Things With Big Implications)

• Smoke alarms: test yourself and replace batteries at least once a year (battery models), and replace the whole smoke alarm about every 10 years (or per manufacturer instructions). (usfa.fema.gov)
• Dryer fire prevention: clean the lint screen with every load, and regularly clean the vent/duct and behind the dryer where lint gathers; replace plastic/foil accordion ducts with metal ducting. (cpsc.gov)
• Check fire extinguishers: make sure the pressure gauge is in the green, the pin is present, and there’re no obstructions interfering with access. (Replace or service per the label; many are disposable after either use or a set service life.)
• If you have a fireplace/wood stove: check the visible firebox and damper area for cracks, missing mortar, or heavy soot; schedule a professional inspection/cleaning if you see any buildup or if you’ve never had it checked since moving in.

2) Water: Shutoffs, Pressure, and the Slow Leaks That Wreck Houses

Water damage tends to be less about one big catastrophe and much more about a valve you can’t shut off, pressure that no fixtures can reliably handle, or a tiny drip that lives behind your vanities. Your annual goals:

• Confirm you can stop the water fast.
• Verify that the pressure is at least sane.
• Exercise the main water shutoff: Turn it fully off, then fully back on (if hard to move, won’t fully turn off, or drips after reopening, make plans for a plumber visit, don’t wait for those supply lines behind the drywall to burst).
• Check the fixture shutoffs: Under every sink and behind every toilet, gently turn off and back on the valve. Replace any shutoffs that seize, leak at the stem, won’t close.
• If you’ve never put a pressure gauge on your house’s plumbed water supply, now’s your chance. You want your average running pressure to be less than 80 psi. If testing shows otherwise, ask your plumber. Test incoming water pressure: attach a pressure gauge to an outdoor hose bibb, ensure all fixtures are off, then read the pressure. EPA WaterSense recommends that fixtures do best at around 45–60 psi and points out that a PRV could help keep your water pressure within that range. (epa.gov)
• Water heater temperature safety: set to around 120°F to lessen scald risk (and verify this actual temperature at the tap using a thermometer). (cpsc.gov)
• Scan for hidden leaks: check under sinks, around the base of your water heater, and at the water supply hoses for your washing machine. Investigate rust stains, mineral crust, swollen cabinets, or moldy smells on the spot.

Moisture Control: Sump Pumps, Grading, and “Mystery Musty” Basements

• Sump pump test (if you have one): if the pit is mostly dry, pour several gallons of water into it to trigger the float switch (or carefully lift the float). Confirm that the pump comes on and discharges water outside. Ensure it shuts off cleanly (not with a vigorous on/off cycling).
• Battery backup (if you have one): press the test button and confirm that the alarm (or indicator lights) indicates what you’d expect. Replace the battery on schedule—backup pumps fail when the battery’s old.
• Downspouts and splash blocks: confirm water is moved away from the foundation and not dumping at the house corner.
• Window well drains and basement window weep paths: make sure they’re free of leaves/silt so water has a way out.
• Dehumidifier: clean the filter, sanitize the bucket or drain hose, and verify it’s actually draining. A kinked hose can silently overflow.

4) Air: HVAC, Ventilation Fans, and the Ducts You Don’t Think About Until They’re Broken

• Change HVAC filters on their schedule (typically every 1–3 months, but follow your system and indoor air needs). Mark filter replacement date with a permanent marker.
• Clean the A/C condensate drain, and check the overflow safety switch/pan if accessible. (A clogged drain may lead to ceiling or closet water damage otherwise.)
• Bathroom fans: confirm that the fan actually blows outdoors (hold up a square of toilet paper—there should be suction holding it to the grille).
• Dryer exhaust outside: during dryer use, confirm the flap opens and airflow is strong when it does. Weak airflow = restriction.
• Kitchen range hood: verify airflow if it vents outside; replace/clean grease or charcoal filters if recirculating.

5) Electrical: The Safety Devices We’re All Supposed to Test (But Usually Don’t)

• Test GFCI outlets/breakers: press “TEST”; power should cut. Press “RESET” to restore. If not, replace the unit.
• Test AC breakers: follow manufacturer’s instructions in the panel using the test button. If it won’t reset, or if it trips unexpectedly, call an electrician.
• Panel labeling: make panel names unambiguous, not just “lights” or “bedroom”.
• Outdoor outlets/covers: replace cracked/brittle covers and check “weather gaskets”.

Indoor Air Quality Wild Card: Radon (Especially if You Have a Basement!)

1. If you’ve NEVER tested: do a test (DIY kit or pro). Kits are cheap and usually reliable.
2. If you tested years ago: retest after major air sealing, HVAC changes, or using the lower level more.
3. If radon is at or above EPA action levels (generally 4 pCi/L): consult a pro, install mitigation, then retest. (cdc.gov)

7) Septic Systems (If You Have One): Schedule Beats Surprises

• Find and map the system: locate the tank access, drainfield area, and flow direction. Sketch with measurements from landmarks.
• Book inspections/pumping proactively: slow drains/odors are late signs. Pump every 3-5 years; inspect every 3 years (or per local code or system type). (epa.gov)
• Protect the drainfield: keep off vehicles, heavy sheds, and deep-rooted trees.
• Watch water use: spread laundry loads, fix running toilets, avoid big surges.

8) Exterior “Connectors”: Where Water and Air Sneak In

• Gutters and downspouts: clean and flush; confirm water exits away from the foundation—not onto walkways or behind gutters.
• Siding/trim/caulk: check around penetrations (hose bibbs, vents), above windows/doors, and deck-to-house connections.
• Deck and porch safety: look for loose railings, rusty fasteners, soft spots, ledger board issues.
• Outdoor vents: ensure bath fans, range hoods, dryer vents have intact hoods/screens and freely move (no lint, paint, or nests).

9) Appliances That Quietly Cause Expensive Failures

• Refrigerator coils (if accessible): vacuum dust for compressor efficiency.
• Dishwasher: pull & rinse filter, check door gasket, look for water stains under the unit.
• Washing machine hoses: upgrade to braid stainless if still using rubber; check for bulges or cracks and shutoff valve function.
• Garage door: test safety photo-eye and auto-reverse; lubricate hinges/rollers if manufacturer recommends (usually not the tracks).

The “I Forgot I Had That” List (Special Systems):

• Whole-home generator: log “exercise under load”, battery age, and fuel.
• Irrigation/backflow device: check/test per your area’s code, inspect heads and valves for freeze damage and leaks.
• Well: monitor pressure tank behavior. Short cycling = bad tank or switch. Test water quality regularly.
• Water softener/filtration: refresh salt, replace filter as scheduled.
• Solar panels: keep free of debris, monitor for unexpected drops in production.

Mistakes That Keep Homeowners Stuck in Repeat Repairs

• Only maintaining what you can see. Hidden systems are where the big damage happens. Better: At least one full audit targeting hidden connectors and safety devices every year.
• Assuming a shutoff valve will work in an emergency. Valves seize if untouched for years under pressure. Better: Exercise and label all shutoffs every year. Replace bad valves proactively.
• Cleaning the lint screen but never the vent. Clogged vents = fire risk and inefficiency. Better: Ensure strong outside airflow, and schedule vent cleaning regularly.
• Ignoring water pressure. Too high may burst hoses, too low can mean hidden leaks. Better: Test annually and install a PRV if pressure’s high.
• No paper trail. Without records, claim or repair time is a guessing game. Better: Keep a log of maintenance, with dates, receipts, and photos.

A Simple Annual Schedule You Can Copy

1. Pick your month. (Example: March or October).
2. For anything that you will book with a pro, get on their schedule 2 -4 weeks ahead of time.
3. Do your DIY audit in one afternoon: fire + water + moisture + vents + electrical.
4. Log everything and set reminders for the next due date (filters, detectors, septic, radon retest).
