Why Is My A/C Line Frozen and How Can I Fix It? Quick and Easy Tips

When summer heat increases, the use of air conditioners heavily increases all over Australia. If you feel that your AC is not working properly, and during the manual inspection, you notice that the AC line is completely frozen. That’s not an uncommon phenomenon, and there can be multiple factors causing it.

Once you have noticed a frozen line, you might be thinking of getting an air conditioner service. But before doing so, it’s always preferable to identify the air conditioner’s core problem. Let’s first discuss the causes that lead to freezing the A/C line, and then we will look at some quick fix suggestions.

What causes the freezing of the A/C line

The first step is to switch off your air conditioner and set the thermostat to fan mode. Wait until the line defrosts so you can inspect the airflow. Evaporator coils are the most important component of an HVAC system; too much cooling of these coils leads to air conditioner problems. These evaporator coils have refrigerant filled in them, which absorbs heat from the air and transfers the cooling effect to users.

So any pertinent problem with the HVAC system leads to a compromise in the heat exchange process. So when the evaporator absorbs less heat , it eventually leads to  the accumulation of ice over the coils.

Some other solutions along with quick Fixes

Before getting an air conditioner service, look for these other reasons causing the freezing of A/C lines:

• A dirty air filter usually affects the optimal working of your unit. If dirt accumulates in it or it gets clogged in any way, it usually prevents airflow. So to ensure proper air conditioner maintenance, it’s advisable to change the air filter on a monthly basis.
• The dirty evaporator coil can also be problematic, as it also compromises the flow of air, thus resulting in frozen A/C lines.
• If by any means supply vents are closed, this also results in limiting the airflow. Usually, people think that closing these vents will lessen the burden on their HVAC unit, and they would get lesser electricity bills, but unfortunately, they end up with a frozen A/C line.
• Similarly, if external vents are closed for any purpose, it also leads to problems that necessitate an air conditioner repair immediately.
• A broken or malfunctioned blower fan results in a lesser amount of air over the evaporator coils. The blower fan mainly brings the warm air into the system while pushing the cold air into your home. In such a situation, air conditioner repair becomes inevitable. Otherwise, a collapsed fan can ultimately yield the same outcome as a frozen A/C line. If air conditioner repair is delayed, it can even lead to even more expensive repairs.

The Bottom Line

In addition to the aforementioned causes, collapsed air ducts or low refrigerant levels prove to be the main reasons for frozen lines. Though cleaning and a few of these fixes are usually easy to perform, it’s always preferable to hire a professional to analyze the whole HVAC system. Homeowners generally focus on the central issue, but leave other ones unattended, resulting in more expensive air conditioner repairs. So, it’s always recommended to hire a professional to prevent major issues.
