Houses rarely fail all at once. They fail on a schedule you can read in advance: filters clog on a curve, sediment settles a little more every month, lint accumulates a load at a time, and the water heater gives up on a cold morning years after it quietly started dying. This calendar is the counter-schedule. Print it, put it on the fridge, and work it — most tasks take minutes, cost nothing, and exist to keep small wear from ever becoming an emergency bill. Everything else on Arcturus Vega links back to this page, because this page is where the expensive problems get prevented.
The Monthly Round (About 15 Minutes)
Do these on the same day each month — the 1st works — and the rest of the calendar gets much easier.
- Test smoke and carbon monoxide alarms (press the test button) — the cheapest life-safety habit there is; a silent detector protects no one.
- Test every GFCI outlet (Test button, then Reset) — ground-fault protection only works if the mechanism still trips.
- Check the HVAC air filter; replace it if it's dirty — airflow protects your furnace, your AC coil, and your power bill all at once.
- Look under every sink and around the water heater for leaks — small drips announce themselves early, and water damage is the most expensive surprise in a house.
- Clean the dishwasher filter (usually a twist-out cylinder in the tub floor) — prevents smells, poor cleaning, and strain on the pump.
- Run water in rarely used drains and floor drains — keeps the traps full, which is what blocks sewer gas from entering the house.
- Clean the dryer's lint screen — after every load, technically, but check it on the round if loads slip through unscoured.
January
- Check pipes in unheated spaces (garage, crawl space, exterior walls) during cold snaps — burst pipes are winter's most destructive failure.
- Know where your main water shutoff is and confirm it turns — the time to learn this is not during a flood.
- Look in the attic for leaks, frost, or daylight — winter weather finds roof problems first.
- Vacuum refrigerator coils (first of twice a year) — dusty coils make the compressor run longer for the same cold.
February
- Inspect washing-machine supply hoses for cracks, bulges, or rust at the fittings — a burst washer hose can flood a laundry room in minutes.
- Test the water heater's temperature-and-pressure (T&P) relief valve — lift the lever briefly and let it snap back; a stuck valve is a genuine hazard, not a nuisance.
- Deep-clean the range hood filter — a grease-loaded filter is both a fire risk and a useless one.
March
- Book the professional AC tune-up before the spring rush — you'll get a better appointment and a system checked before the first hot week.
- Clean gutters and downspouts — winter debris plus spring rain is the recipe for overflow against the fascia and foundation.
- Test the sump pump if you have one — pour in water and watch it kick on before the wet season tests it for real.
April
- Inspect the roof from the ground after winter storms — lifted shingles and damaged flashing are far cheaper in April than after a summer of leaks.
- Turn outdoor faucets back on and check each one carefully — a pipe that froze and split in January announces itself the first time you pressurize it.
- Start up the irrigation system and walk each zone — broken heads and misaimed sprayers waste water where you can't see it.
May
- Rinse the outdoor AC condenser coil with a garden hose (power off at the disconnect first) — a dirt-matted coil can't shed heat, and your bills show it.
- Flush the AC condensate drain line — a clogged drain backs water up into the indoor unit and whatever is beneath it.
- Set ceiling fans to run counterclockwise for the cooling season — downdraft is the whole point in summer.
June
- Test the garage door's auto-reverse with a roll of paper towels on the floor — a door that won't reverse is a safety failure, not a quirk.
- Lubricate garage door tracks and hinges — noise is wear asking for attention.
- Check the dryer's outdoor vent flap while the dryer runs — it should open fully with exhaust air; a lazy flap means lint is building up inside.
July
- Vacuum refrigerator coils (second of twice a year) — peak summer is when a struggling fridge works hardest.
- Flush rarely used drains again — trap water evaporates faster in hot weather, and sewer-gas smells follow.
- Confirm the AC condensate drain is dripping freely — mid-season clogs are common during peak runtime.
August
- Test toilets for silent leaks — a few drops of food coloring in the tank; color in the bowl 20 minutes later means the flapper is leaking water around the clock.
- Clean bathroom exhaust fan grilles — a dust-blanketed fan moves little air, and bathroom moisture is mold's favorite food.
- Walk the foundation and grading — soil should slope away from the house everywhere; summer storms will find every low spot.
September
- Flush the water heater tank (annual) — sediment is the tank's number-one killer; a garden hose on the drain valve until the water runs clear undoes a year of it.
- Book the furnace tune-up and test-fire the heating system on a mild day — the first cold night is the worst time to discover it won't light.
- Check the water heater's base and fittings again while you're there — see the monthly round's reasoning, applied at the source.
October
- Clean the dryer vent duct end to end — October is Fire Prevention Month, and clogged dryer vents are a leading cause of house fires; this is the calendar's highest-value hour.
- Clean gutters again after leaf fall — wet leaves left in place rot fascia boards over the winter.
- Shut down irrigation in cold climates — draining or blowing out lines before the first freeze prevents spring surprises. (Blowouts with compressed air are a judgment call — many homeowners hand this one to a pro.)
November
- Winterize hose bibs and exterior faucets — close the interior shutoffs, open the exterior taps, and leave them open.
- Insulate exposed pipes in unheated spaces before the first hard freeze — foam sleeves are cheap and burst pipes are not.
- Check weatherstripping on exterior doors — if you can see daylight or feel a draft, you're heating the outdoors.
- Replace smoke and CO alarm batteries at the fall clock change if your units don't have sealed 10-year batteries — the date change is the reminder you'll never forget.
December
- Watch circuit loads during holiday lighting season — space heaters plus decorations on one circuit is how breakers earn their keep; if a breaker trips, treat it as information (see the Arcturus Vega rule below).
- Check the fire extinguisher gauges — needle in the green, pin in place, and know where each one lives.
- Restock the emergency kit — flashlights, batteries, water, and the flashlight batteries specifically.
Every Few Years (Put Actual Dates on These)
- Every ~3 years: inspect the water heater's anode rod — this sacrificial rod corrodes so your tank doesn't; replacing a spent rod (a part costing roughly $20–$50) can add years to a tank that typically lasts 8–12 years. First removal on an old tank can be stubborn — many homeowners make this a plumber's job.
- Every 3–5 years: pump the septic tank, if you have one — interval depends on household size and use.
- Every 3–5 years: professional inspection of the electrical panel — loose connections and heat damage hide here, and the inside of the panel is professional territory on purpose.
- As they age: replace rubber washer hoses with braided stainless lines — and then stop worrying about them quite so much.
What This Calendar Deliberately Leaves Off
Notice what's missing: nothing on this page involves a gas line, refrigerant, or opening your electrical panel. That's not an oversight — those systems get professional service visits (the March and September HVAC tune-ups, the periodic panel inspection), and everything you do around them is observation: smells, sounds, leaks, scorch marks. Your job in those systems is to be the world's best early-warning sensor.
FAQ
I missed a month. Do I start over? No. Do the monthly round today, then pick up with the current month. The calendar is a loop, not a streak — the only bad month is the one where you quit entirely.
How much time does this actually take? The monthly round is about 15 minutes. Seasonal items run 30–60 minutes a few times a year, and the annual jobs — water heater flush, dryer duct — are a half-hour to an hour each, or a line item on a pro's visit if you'd rather.
Which of these should I never DIY? Anything involving gas lines, refrigerant, or the inside of your breaker panel. Everything on this calendar was chosen to stay outside that line: checks, cleanings, filters, and flushes only.
