[2026-4-11 | Equipment Maintenance] Cleaning and Inspecting a Room Air Conditioner Before Summer
We cleaned and inspected the room air conditioner ahead of summer.
We cleaned the filter, carried out a basic internal clean, and checked the unit's operation.
Air conditioners are used more frequently as temperatures rise, making maintenance at this time of year important.
The unit is now operating normally.
