When your home’s AC unit has weak airflow, you’ll find that the rooms won't cool quickly, even though the equipment is blowing chilled air. If your system’s cooling capacity isn’t functioning optimally, there are several reasons for the problem. Here are the most common culprits for an air conditioner’s weak airflow.

What Causes Weak Airflow in AC Units?

1. Frozen Evaporator Coil

The AC chills hot air by passing it over the evaporator coil. This part contains a liquid coolant that turns into a gas as it absorbs warmth from the hot air. If the coolant leaks, it’ll freeze the surrounding components and form ice. The accumulation will create a barrier that blocks the air’s flow as it moves over the coil and out the duct system.

2. Clogged Air Filter

The AC unit has an air filter to trap airborne particles and prevent them from circulating through the home. The screen should be changed or cleaned every one to two months to maintain air quality. If ignored, the air will have difficulty passing through the screen and entering the room, resulting in reduced airflow.

3. Malfunctioning AC Blower

The blower pushes cold air out the ducts, and a lack of power will inhibit its duty. This issue can be caused by a malfunctioning motor, which requires professional attention. If the problem is caused by dirty fan blades, wipe them gently with a clean, damp cloth to remove the buildup.
