Portable AC Maintenance Checklist

In season, clean the air filter every two weeks, check drainage and the exhaust setup, and keep the coils and vents clear. Off season, dry everything, coil the hose neatly and store the unit upright and covered.

• Remove and clean the air filter (rinse or vacuum as the manual allows); let it dry before refitting.
• Check the drain outlet or tank and empty it if your model collects condensate.
• Wipe the intake and outlet grilles free of dust.
• Look at the window kit for gaps that let warm air back in.

• Vacuum the evaporator and condenser fins gently if they are accessible; do not bend them.
• Check the exhaust hose for kinks, cracks or loose adapters.
• Re-seal the window kit and check the hose still vents outdoors.
• Confirm the unit sits level so condensate drains correctly.

1. Run the unit in fan-only mode for a while to dry the inside.
2. Drain any remaining condensate completely.
3. Clean the filter and let it dry fully.
4. Coil the hose without kinks and store the adapters with the unit.
5. Store upright, covered, in a dry place; do not stack heavy items on it.

• Running months with a clogged filter, which strains the unit and cuts cooling.
• Storing the unit with water still inside, which causes mold and odors.
• Bending the fins while cleaning, which reduces airflow.
• Losing the window kit and re-installing with a leaky setup next season.
