Troubleshooting Guide for a Frozen AC Unit

Living in the hot and humid summer months can be exhausting and uncomfortable, especially when your air conditioning unit stops cooling the home. One of the most common problems a system can suffer from is a frozen AC unit. There are symptoms to look out for, a few simple troubleshooting steps, and if all else fails, contacting a reliable technician is essential.

What Causes a Frozen AC Unit?

Frozen AC units are caused by an overworked system, clogged air filters, and blocked air ducts, which can harm the system as a whole. Furthermore, they can also be caused by low refrigerant levels, and a thermostat which is not accurately set. When all of these components are either worn-out or not functioning properly, the frozen AC problem begins.

Signs of a Frozen Unit

This problem will often show signs in a few different ways. The most common symptom is a blocked air conditioner unit and a lack of air flow. Your air conditioning unit will fail to cool the room, even though the fan is working. Additionally, you may notice a decrease in air pressure from the vents, as well touches of frost or even an icy buildup on the outside or on the inside coils of your air conditioner.

Troubleshooting Frozen AC Units

Before calling a technician, there are a few steps you can take to troubleshoot your frozen air conditioner unit on your own. This process should always begin by inspecting the air filter and ensuring it is not clogged or filled with debris. If the filter is clogged, then it should be replaced immediately.

Next, check to make sure your condensate drain line is clear and properly running. If the line is blocked, a technician can use a snake to clear the drain line. If the drain line is clear, but the system is still not performing as it should, then the air handler’s blower wheel and blower motor should be inspected for proper operation.

In some cases, a dirty evaporator coil can cause AC unit freezing. This coil should be inspected and cleaned, if required. Furthermore, check to make sure your outdoor unit is not covered with foliage or other debris, as this can block the air flow and restrict the condenser’s operation.

Call a Technician

Sometimes, a damaged part or an inadequate amount of refrigerant can cause a frozen AC unit. If troubleshooting fails to resolve the issue, a reliable and licensed HVAC service should take a look at the system to diagnose and repair the problem correctly.
