Before long-term storage during fall and winter, your air conditioner needs a seasonal maintenance check. Without it, you may experience odors or poor cooling performance when you turn it on next year. Little Master shares key maintenance tips: **Steps before shutdown:** 1. On a sunny day, run the unit in fan mode for 2-3 hours to dry internal moisture and prevent mold growth. 2. Remove, clean, and thoroughly dry the filters before reinstalling them. 3. Cover the indoor unit with an AC cover or dust-proof cloth. 4. Unplug the power cord to avoid standby power consumption and lightning damage risks. 5. If possible, also cover the outdoor unit with a dust-proof cover. **When restarting:** 1. Remove the cover first and inspect the unit for any visible issues. 2. Open windows for ventilation and run the unit in fan mode for 30 minutes. 3. Verify that both cooling and heating functions are working properly. 4. Check for unusual noises or water leaks. 5. We recommend a professional cleaning before regular use. **Important reminders:** - Central air conditioning systems require professional seasonal maintenance. - For units not used for extended periods, plug them in once a month to prevent compressor oil from settling. - Remove batteries from the remote control to prevent leakage and corrosion. Little Master offers a comprehensive seasonal maintenance package, including cleaning, inspection, and dust protection.
