Dirty filters, low refrigerant, and a clogged radiator can reduce cooling efficiency.

Poor cooling performance is often caused by dirty filters, low refrigerant level, or a clogged radiator. In some cases, the indoor fan or electronic control unit also affects the system’s performance.

Without seasonal cleaning and inspection, the unit consumes more electricity, cools the room more slowly, and becomes more likely to fail. Timely service protects both comfort and the lifespan of the appliance.
