The First-Time Homeowner's Maintenance Calendar (Month by Month)

Nobody hands you a manual when you buy your first home — so small tasks ignored at the right time become expensive repairs at the wrong time.

This calendar fixes that: month by month, the short list of tasks that keeps a house healthy — most months take under two hours. Every month: check the HVAC filter, test the smoke and CO alarms, and press the test button on your GFCI outlets; gas, electrical, and roof work belong to pros. This page is the companion to our own book on the same topic:

January: Deep Winter Defense

Check the HVAC filter. The house rule on every page of this site: check it monthly and replace it every 1–3 months — ENERGY STAR's floor is every three months, and the DOE says to clean or replace filters monthly during seasons of peak use. A clogged filter raises energy costs and can damage the system. How to change it, and which way the arrow goes.

Test smoke alarms. Press the test button on every alarm until it sounds, and note the manufacture date printed on the back of each unit. The full monthly routine. Any alarm past its date gets replaced, not repaired: our alarm picks.

Look under sinks for dampness or drips — cold contracts connections, so winter is when small leaks become big ones. Know where your main water shutoff is before you ever need it.

Test for radon. January is National Radon Action Month, and the EPA and the Surgeon General recommend testing every home below the third floor. If you never have, a short-term kit runs as little as two days: how to test and which kit to use.

February: The Quiet Month

February is the make-up month: finish anything January didn't get, then do two checks.

Test GFCI outlets. Press "test" on every GFCI (kitchens, bathrooms, garage, outdoors, laundry), then "reset". Any outlet that won't trip or reset needs replacing — a like-for-like swap is a careful-DIY job (see our DIY guide), or have an electrician do it.

Peek into the attic on a cold morning: frost on the roof deck, stained insulation, or daylight where it shouldn't be are early signs of leaks — far cheaper to catch now than after spring rain. Dark staining on the roof boards themselves can mean mold in the attic, and loose, pebble-like insulation may be vermiculite, which the EPA says to leave undisturbed.

March: Wake the House Up

Book the spring AC service before contractors get busy. ENERGY STAR recommends annual pre-season professional checkups — cooling equipment in spring, heating in fall.

Clean the gutters (first of two). Spring cleaning clears winter debris ahead of spring rain. West Virginia University Extension recommends at least twice a year, more often where severe storms are common; this calendar puts the cleanings in spring and fall. Confirm downspouts carry water away from the foundation. How to do it without a ladder.

Scan the roof from the ground with binoculars: missing, curled, or damaged shingles, lifted flashing. Don't climb up — note what you see and call a roofer if anything looks off.

Test the sump pump. Pour a bucket of water into the pit until the float rises: the pump should start, drain the pit, and shut off. If it doesn't, fix it before the spring rains — our spring checklist covers the details, and our sump pump guide covers replacements and battery backups.

April: Exterior Reset

Check the HVAC filter — it likely needs a change after the winter heating season.

Replace the refrigerator water filter if your fridge has a water or ice dispenser (first of two). Samsung, LG, Whirlpool, GE Appliances, and Frigidaire all say about every six months. How to find the right filter, flush it, and reset the light.

Inspect exterior caulk and paint. Cracked caulk around windows, doors, and trim lets water in and causes rot. Touch up what you can reach; higher work is pro territory. Sealing gaps where pipes and wires enter also helps keep ants out.

Check washing machine hoses for bulging or cracking. If yours are rubber and more than a few years old, swap them for braided stainless-steel hoses — a screw-on job with the supply valves shut, or a five-minute favor for a plumber who is already there. If the washer won't drain or spin, see washing machine not draining.

May: The Big Preventive Month

Clean the dryer vent. NFPA estimates about 13,820 home fires a year involved clothes dryers (2014–2018), with failure to clean the leading factor (about a third). Clean the lint trap after every load and the vent pipe annually; never run the dryer while asleep or away.

Flush the water heater. Rheem calls for yearly flushing to remove sediment that cuts efficiency and corrodes the tank. Before you drain: switch an electric heater off at the breaker (the elements burn out in seconds if they run dry) or turn a gas heater's control to "pilot" (or "off," as the label directs; "vacation" is only a low setting, and the burner can still fire), and let the tank cool for a couple of hours. Run a hose from the drain valve to a floor drain or outdoors, and know that an old plastic drain valve may not seal again once opened. Then test the temperature-and-pressure (T&P) relief valve by briefly lifting its lever. The water that comes out is scalding, so first confirm the discharge pipe runs down to a drain or bucket and keep hands clear — if there is no discharge pipe, skip the test and call a plumber. If the valve doesn't release water and stop, call a plumber. Same caution: if the valve is old and hasn't been tested in years, let the plumber do this — a long-neglected lever can start dripping after it's lifted.

Confirm the water heater is set to 120°F — the Department of Energy's recommendation for most households. Measure the hottest tap with a thermometer to make sure the dial is honest.

June: Cooling Season Check-In

Dial in the thermostat. ENERGY STAR's starting point is 78°F or higher when you're home in summer, higher when you're away. A schedule (or programmable thermostat) beats guessing daily. If the AC runs but the house stays warm, see AC not cooling.

Check the fridge temperature. The FDA recommends 40°F or below (freezer at 0°F). Verify with an appliance thermometer — most fridge dials don't show real temperatures. If it won't hold 40°F, see refrigerator not cooling.

Clear the AC condensate drain. A clogged drain line by the indoor unit causes mysterious ceiling water stains. Switch ceiling fans to summer mode to push air downward.

July: Outdoor Living

Inspect the deck. Look for loose boards, popped nails, wobbly railings, and soft spots that signal rot — a failing board is most likely to hurt someone in summer. Confirm the flashing where the deck meets the house is intact.

Deep-clean the range hood filter (most metal filters go in the dishwasher — grease buildup is both a fire risk and a performance killer), and after a heavy storm, check where water pools near the foundation. Trim branches touching the roof or siding.

August: Prep for Fall

Air-seal the envelope. Check weatherstripping — if you can see daylight around a closed door, it's leaking heated air. Re-caulk gaps flagged in April; small air-sealing jobs pay back every winter.

Check attic ventilation (vents and soffits not blocked by insulation) and test smoke alarms — then read the manufacture dates: any alarm at or past 10 years old gets replaced now, not later, per the NFPA (October is just the reminder to re-check the dates).

September: Heating Season Prep

Book the fall furnace service — ENERGY STAR's second annual pre-season checkup. On gas units the technician should verify safe combustion and inspect the heat exchanger; a cracked heat exchanger is a carbon-monoxide risk.

Change the HVAC filter before heating season, and check CO alarms: most expire after 5–10 years depending on the model — the replace-by date is printed on the unit — and combination units follow the shorter life. Test monthly.

Book the chimney inspection if you have a fireplace or wood stove: NFPA 211 calls for an inspection every year, and CSIA says to sweep at 1/8 inch of buildup. Sweeps fill up fast once the first cold nights arrive. Our first-fire checklist covers the rest.

October: Winterize

Winterize outdoor plumbing. Disconnect and drain garden hoses, shut off the interior valve to exterior faucets, and drain the line. Frozen outdoor plumbing bursts in the first hard freeze. Step by step, including frost-free faucets. Sprinkler system too: drain it or have it blown out. Before a cold snap, check your zip code's freeze risk.

Clean the gutters (second of two) after the leaves finish falling and before the first hard freeze — clogged, frozen gutters contribute to ice dams that push water under shingles.

Replace expired smoke alarms (NFPA: at least every 10 years from the manufacture date — hardwired and 10-year-battery units expire too). Stock up on furnace filters while you're shopping; the filter finder gives the size and MERV rating to buy.

Replace the refrigerator water filter (second of two), six months after April's. Step by step.

Bleed hot-water radiators once the heat has been running a few days, so trapped air stops leaving the tops cold. How to bleed radiators.

November: Seal and Inspect

Inspect attic insulation — compressed, stained, or missing insulation over living space is money escaping through the ceiling. Note problem areas for a winter insulation project.

Check window and door locks (a window that won't lock won't seal), test GFCI outlets, and walk the exterior for anything winter will punish: loose siding, detached downspouts, firewood against the house.

December: Close the Year Out

Do the year-end safety sweep: test every smoke and CO alarm, confirm each fire extinguisher gauge is in the green zone (the makers say to glance at it at least monthly), keep the area around the furnace and water heater clear of stored items, and run the garage door's monthly auto-reverse test.

Review the maintenance budget. Compare what the house actually cost against what you saved, then update next year's budget for the ages of your big systems. If the furnace is 18 or the water heater is 14, next year's plan should say "get quotes," not "hope."

Frequently Asked Questions

How often should I change my HVAC filter?

Check it every month and change it every 1–3 months: ENERGY STAR's floor is every three months, and the DOE says to clean or replace filters monthly during seasons of peak use. Homes with pets, allergies, or 1-inch filters usually land at the short end of that range.

How often do smoke detectors need to be replaced?

The NFPA says to replace them at least every 10 years from the manufacture date on the back — hardwired and 10-year-battery models too. Install them inside every bedroom, outside each sleeping area, and on every level including the basement; test them monthly.

What else gets replaced on a schedule?

The HVAC filter every 1–3 months (the furnace filter finder gives your size and interval), the refrigerator water filter about every six months (how to change it), and smoke alarms 10 years from the manufacture date.

Is cleaning the dryer vent really a fire-safety issue?

One of the biggest. NFPA data shows an average of about 13,820 home dryer fires per year (2014–2018), roughly a third from failure to clean. Clean the lint trap after every load, the vent pipe annually, and never run the dryer while asleep or away.

Bottom Line

Twelve months, a few dozen small tasks, and two habits that never stop: check the HVAC filter every month, test the alarms and GFCI outlets every month. A house that gets its small maintenance on schedule rarely surprises its owner.
