Air conditioner filter Its manufacturing has also been elevated to a new stage; so, what aspects should we pay attention to during use?
Maintaining the air-conditioning filter is of paramount importance for the air-conditioning unit, as it directly affects the cleanliness of the indoor air; therefore, routine maintenance of the air-conditioning filter is a key component of central air-conditioning system upkeep. Common malfunctions caused by a clogged and dirty air filter and poor cooling or heating performance include: when the filter is heavily clogged, the indoor unit’s air outlet temperature drops during cooling, yet the airflow does not extend far, indoor air circulation is slow, and the room temperature remains high—similar to the symptoms of a fan running at a low speed. Clogging of the drain pan in air-conditioning filters (for cabinet and wall-mounted units): when the filter becomes excessively dirty, dust particles enter the gaps and accumulate on the evaporator surface, then flow into the drain pan along with the condensate. Over time, this leads to blockage of the drain pan and subsequent water leakage from the indoor unit. Evaporator blockage in air-conditioning filters (for cabinet units): in hair salons that use cabinet-type units, if the filter becomes heavily clogged, hair can be drawn by the fan to the back of the evaporator, causing the evaporator to become dirty and obstructing proper heat exchange.
Even after washing Air conditioner filter The evaporator also requires cleaning. During winter, when cabinet-type units are used in public spaces, dust is easily drawn in by the fan and blown onto the back of the evaporator, leading to blockage. Fan blade clogging (in both cabinet and wall-mounted units): Dust accumulates on the filter screen; as the fan motor runs, dust adheres to the fan blades, reducing the clearance between them, which in turn decreases airflow, increases noise, and causes unstable air volume at the outlet. Overheating during heating mode with no defrosting: A clogged filter results in excessively high surface temperatures on the evaporator during heating. The control board detects this and extends the heating duration, causing severe frost buildup on the condenser, which then triggers the outdoor fan to stop while the system continues to operate.
Refrigeration freeze-up: When the air conditioner’s filter is clogged, the evaporator temperature drops very low during cooling, triggering the control board’s frost-protection mechanism, which shuts down the unit and stops cooling. Indoor-unit water leakage: If the filter is clogged and the evaporator temperature remains extremely low during cooling, and the control board lacks frost-protection functionality, ice will form on the evaporator, leading to water leakage from the indoor unit.
