Yearly Home Maintenance Checklist, Month by Month
A yearly home maintenance checklist covers the machinery of the house, not the cleaning. Every month: check the furnace or air-conditioner filter, test the smoke alarms and test the GFCI outlets. Every three to six months: drain a quart from a tank water heater. Twice a year: a professional check-up on the cooling system in spring and the heating system in fall. Once a year: an inspection of every fuel-burning appliance before the heating season. Spread those across twelve months and no single weekend has much to do. The month-by-month card is below.
Maintenance is not cleaning
This site already keeps two cleaning calendars: the seasonal cleaning checklist for the four turning points of the year, and the long fall cleaning checklist for closing the house before winter. Neither is repeated here. This list is the other half: the filters, valves, alarms and outlets that keep working unnoticed until the day they fail.
The rule for this card is the same as for anything with a safety consequence: every interval comes from a manufacturer or an agency, or it is marked as a house habit. Where your appliance manual says something different, the manual wins.
Every month: three checks, ten minutes
The furnace or air-conditioner filter. ENERGY STAR’s maintenance checklist says to “inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump”, because “a dirty filter can increase energy costs and damage your equipment, leading to early failure.” Checking doesn’t mean replacing every month. Pull it out, hold it to the light, and change it when it’s grey.
The smoke alarms. The U.S. Fire Administration’s monthly test is covered in the fall list, along with the yearly battery swap and the 10-year replacement. Press the button on the first of the month.
The GFCI outlets. These are the outlets with TEST and RESET buttons, usually in the kitchen, bathrooms, laundry and outside. The Electrical Safety Foundation’s one-page how to test a GFCI says to test them “every month”: press RESET, plug in a nightlight, press TEST, and the light should go off; press RESET and it should come back on. If the light stays on after TEST, ESFI says the outlet “is not working properly” and needs an electrician, because a GFCI that doesn’t trip gives no shock protection.
Every three to six months: the water heater
Sediment settles at the bottom of a tank water heater. The University of Florida’s extension guide on energy-efficient water heaters says: “If you have a tank-style water heater, drain about a quart of water from the water tank every 3–6 months,” to remove the sediment that “slows down heat transfer and lowers the efficiency of your water heater”, and to follow the manufacturer’s recommendations for your unit. That’s a bucket under the drain valve at the bottom of the tank. The water comes out hot, so keep the children out of the room.
The same guide says most water heaters last 10 to 15 years, and that once yours is past 10 it’s worth starting to shop. Write the install date, or the date on the unit’s label, on the card.
Twice a year: the heating and cooling check-ups
ENERGY STAR recommends a contractor’s “annual pre-season check-ups”, with the timing spelled out: “check the cooling system in the spring and the heating system in the fall”, because contractors get busy once summer and winter arrive. It suggests planning them “around the time changes in the spring and fall”, which gives each one a fixed date on the card. Its list of what the visit covers includes the condensate drain, electrical connections and, on the heating side, the gas or oil connections, burner and heat exchanger. Those are jobs for the professional, which is why this is a phone call and not a Saturday project.
Once a year: the fuel-burning appliances
EPA’s carbon monoxide page passes on the Consumer Product Safety Commission’s advice to have “an annual professional inspection of all fuel-burning appliances” (furnaces, stoves, fireplaces, clothes dryers, water heaters and space heaters among them) and CO alarms “on each level outside each sleeping area.” The fall list books this inspection as its first job and covers the CO alarm, so on this card it’s one line in September.
The month-by-month card
The three monthly checks run all year. This is what sits on top of them.
| Month | Maintenance job | Source of the interval |
|---|---|---|
| January | Water heater: drain a quart. Check the caulk around the tub, shower and kitchen sink. | UF extension (3–6 months); caulk is a house habit |
| February | Refrigerator coils and door gaskets, if your manual calls for it | Manufacturer’s manual |
| March | Spring time change: book the cooling check-up | ENERGY STAR |
| April | Water heater: drain a quart. Outside taps back on and checked for drips. | UF extension; taps are a house habit |
| May | Cooling check-up done before the first hot week | ENERGY STAR |
| June | Clean the washing machine | Manufacturer’s manual |
| July | Water heater: drain a quart, and note its age | UF extension (10–15 year life) |
| August | Re-check the furniture straps in children’s rooms before school starts | House habit |
| September | Fuel-burning appliance inspection; the fall list’s safety pass | CPSC via EPA; USFA |
| October | Water heater: drain a quart. Gutters, once the leaves are down. | UF extension; fall list |
| November | Fall time change: the heating check-up should be done by now | ENERGY STAR |
| December | Read the manufacture dates on the smoke alarms and replace any 10 or more years old | USFA |
Two of those rows point to their own methods: the drum-and-seal routine is in how to clean a washing machine, and the bathroom caulk check goes well with a grout clean, set out in how to clean grout. The quarterly water-heater rows sit at the fast end of the 3–6 month range; if your tank has little sediment and the manual allows it, twice a year is still within the guidance.
The back of the tin had a card with the months down one side and, beside each, one job for Grandpa: the furnace man in September, the storm windows in October, the water tank "let off" in spring. It was the only card in his handwriting.
Same card, both handwritings, more rows, because the house now has outlets that test themselves, alarms with expiry dates and a filter that wants checking monthly. Each row carries its source so nobody has to take it on faith.
How to keep the card running
Pin each job to a date that already exists: the first of the month for the three checks, the two time changes for the check-ups, and the first weekend of January, April, July and October for the water heater. Keep a pencil with the card and write the date beside each job when it’s done. A card with dates on it tells you in one look what has slipped. A card without them is only a list.
Keep the tools in one place: a nightlight for the GFCI test, a step stool for the alarms, a bucket and a short hose for the water heater, and a spare filter of the right size. When the filter is on the shelf, the monthly check takes two minutes. When it isn’t, it becomes a trip to the store.
FAQ: yearly home maintenance
What should be on a yearly home maintenance checklist?
Monthly filter checks, smoke alarm tests and GFCI tests; draining a quart from a tank water heater every 3–6 months; spring and fall heating and cooling check-ups; and a yearly professional inspection of every fuel-burning appliance.
How often should you change the furnace filter?
ENERGY STAR says to inspect, clean or change it once a month. Check it monthly and replace it when it looks dirty.
How often should you drain a water heater?
University of Florida extension guidance is to drain about a quart from a tank-style heater every 3–6 months, following the manufacturer’s instructions for your unit.
How often should GFCI outlets be tested?
Every month, according to the Electrical Safety Foundation. If the test button doesn’t cut the power, have an electrician check the outlet.
When should the heating and air conditioning be serviced?
ENERGY STAR recommends the cooling system in spring and the heating system in fall, before contractors’ busy seasons. The two time changes make easy reminders.
