Quick answer
Most of the faults covered on this site have a maintenance step that would have caught them early — a filter, a vent, a seal, a flush. Spreading a handful of these across the year, rather than doing everything at once or nothing at all, is what actually gets maintenance done in practice.
Why spread it across the year
A single overwhelming annual maintenance day rarely happens twice — it gets skipped the following year because it looked like too much. Spreading the same tasks across the seasons, tied to natural triggers like heating season starting or cooling season ending, makes each session small enough to actually complete and easy to remember because it lines up with a seasonal change you already notice.
Spring
| Task |
Why now |
| Clean refrigerator condenser coils |
Good general reset point after a season of heavy kitchen use |
| Check and clean AC filter, clear outdoor unit debris |
Ready the system before the first hot week — see our AC troubleshooting guide |
| Flush the water heater |
Clears sediment that built up over winter’s heavier hot water use |
| Check exterior door and window seals |
Winter weather often loosens or damages seals worth catching now |
| Test smoke and carbon monoxide alarms |
A sensible fixed point to build the habit around |
Summer
| Task |
Why now |
| Clean the dryer vent fully |
Ahead of heavy summer laundry loads from outdoor activity |
| Descale the coffee machine and kettle |
Both run harder in hot weather with more cold drinks and iced coffee prep |
| Check the AC condensate drain |
Peak cooling season is when a blocked drain shows up as an active leak |
| Inspect and clean vacuum filters and brush roll |
Before the summer clean-up season for gardens tracked indoors |

Autumn
| Task |
Why now |
| Test the heating system before it is needed |
Catch a furnace or heat pump fault while it is an inconvenience, not an emergency |
| Check the water heater’s pressure relief valve |
Good annual check point alongside other heating-season preparation |
| Clean gutters and check for drafts |
Standard autumn prep, but also protects plumbing from ice-related issues later |
| Deep-clean the oven |
Before the heaviest cooking season of the year begins |
| Check weatherstripping on doors leading outside |
Ahead of the season it will actually be tested |
Winter
| Task |
Why now |
| Insulate exposed pipes in unheated spaces |
Before the first hard freeze, not after a pipe has already frozen |
| Run washing machine and dishwasher maintenance cycles |
Heavier indoor appliance use during colder months benefits from a mid-season clean |
| Check for draughts around windows and doors |
Most noticeable and most worth fixing during the coldest weeks |
| Test the garage door safety sensors |
Cold weather can affect sensor alignment and battery-backed systems |
Do these on a rolling basis, not seasonally
- Change or clean HVAC and range hood filters monthly during heavy use.
- Empty and check vacuum bins or bags regularly rather than waiting for suction to drop.
- Wipe down washing machine door seals and leave the door ajar between uses.
- Check smoke alarm batteries roughly every six months.
Tie tasks to something you already do
Maintenance sticks best when it rides along with an existing habit — descale the kettle when you notice it is scaling up, check the dryer vent when you notice a longer cycle time, flush the water heater around the same week you do your spring cleaning. Fixed calendar reminders help, but a natural trigger works even better.
