5 Key Causes of Low Airflow in Your AC Unit

Many homeowners are familiar with the effects of low airflow in their air conditioning unit: uneven temperatures, poor comfort levels, and energy bills that rise each month. But what causes this common problem? There are several possible explanations for why your air conditioner isn’t performing as it should. Read on to learn the most common causes of low airflow in your AC unit and what you can do to fix them.

1.    Clogged Air Filter

The first place to look for any air conditioning problem is the air filter. It’s responsible for trapping dirt, dust, and other particles that could otherwise damage the system and reduce airflow. If your filter is clogged, it may not be able to properly clean the air passing through the unit and, as a result, will cause low airflow. Replacing the filter regularly should fix the issue and improve the system’s performance.

2.    Dirty Evaporator Coils

The evaporator coils inside your AC unit are responsible for cooling the air. But if dirt and debris accumulate on them, it can reduce the efficiency of the coils and result in a drop in airflow. Cleaning your evaporator coils should fix this problem. Remember that low air flow means you need ac repairs, so the more you learn about the causes of low airflow, the better you’ll be able to diagnose and fix any issue quickly.

3.    Compressor Issues

If the compressor in your air conditioning unit is not functioning properly, it can lead to a decrease in cooling and airflow. To check whether this is the case, have an HVAC technician inspect your unit. If the compressor has failed, it will need to be repaired or replaced.

4.    Clogged Drain Line

The drain line in your AC unit carries away condensation from the evaporator coils. If this line becomes clogged, it can lead to a build-up of water in your unit, causing reduced airflow. This is more likely to happen in older air conditioning units. Flushing the drain line should clear up the issue and restore normal airflow.

5.    Leaky Ductwork

Finally, leaky ducts are another common cause of low airflow. If any of the ducts running through your home are damaged or worn, they can allow air to escape, reducing the efficiency of your AC unit. Have an HVAC technician inspect and repair any leaky ductwork to fix this issue. You could also consider having your ducts inspected and sealed to prevent any future problems.

To Sum Up

There can be a variety of causes for low airflow in your AC unit, including clogged air filters, dirty evaporator coils, compressor issues, clogged drain lines, and leaky ductwork. To ensure that your system is functioning properly, have it inspected by an experienced technician for AC repair in Palatine to diagnose and fix any underlying problems. Doing so will help you maintain optimal comfort levels in your home while also keeping down energy costs. Thank you for reading!
