Do I really need to do all of this?

The monthly items matter most for day-to-day performance; the yearly items matter most for avoiding a sudden, expensive failure. Prioritize based on your time, but hose inspection and vent cleaning are the two we'd call non-negotiable.

Should I hire someone for annual maintenance or do it myself?

Most of this is genuinely DIY-friendly — vent cleaning for long or inaccessible runs is the main exception where professional equipment helps.

Does this apply the same way to a condo as a house?

Mostly yes, with vent runs being the biggest condo-specific concern (see our guide on dryers that take too long) since condo laundry closets often have longer, more bent duct runs than a house.

When to call a technician

None of this requires a technician — it's maintenance you can do yourself. Call us if something you find during a check (a failing seal, unusual noise, visible wear) needs a real repair.

Monthly

Clean the dryer lint filter before every load, and wipe down the gasket if it's visibly lint-dusty.
Run an empty dishwasher cycle with a dishwasher-safe cleaner to clear grease and mineral buildup.
Check refrigerator and freezer door seals for a tight fit (the dollar-bill test: close the door on a bill and see how easily it pulls out).
Wipe up spills in the oven promptly rather than letting them bake on.

Seasonal: before summer heat (spring)

Vacuum refrigerator and freezer condenser coils, especially for any unit kept in a garage — summer heat makes the compressor work harder against the raised ambient temperature.
Check garage refrigerators and freezers are still sealing well; worn gaskets get a tougher test once ambient temperatures climb.
Confirm dryer vent airflow is strong before the season of more laundry (summer activities, guests) ramps up.

Seasonal: before the holidays (fall)

Have the dryer vent professionally cleaned if it's been a year or more — this is the season ovens and dryers both see heavier use.
Check oven calibration with an oven thermometer before holiday baking season.
Test ice maker production is keeping up if you're expecting guests — a slow ice maker is easier to diagnose calmly in November than to discover on a deadline.

Yearly

Replace the refrigerator water filter on the schedule in your owner's manual (commonly every 6 months, so this is really a twice-yearly task).
Have a professional dryer vent cleaning, especially for longer or bent duct runs common in condos and converted spaces.
Inspect all supply hoses (washer, dishwasher, ice maker) for cracks, bulges or brittleness, and replace any that look worn — a burst hose is one of the most preventable and most damaging appliance failures.
Run a full descaling cycle on the dishwasher and, if your model supports it, the washer, to address a year's worth of hard-water buildup.
