Is your AC Freezing Up? Here’s Why and How to Fix It

In the summertime, a broken air conditioner can be more than just an annoyance – it can make your home almost unbearable to live in. But what if your AC isn’t actually broken? It could be that it’s just freezing up! In this article, we’ll explore why this happens and what steps one can take to fix it.

What Causes My AC to Freeze Up?

Air conditioner freezing is a common problem you may face in summer. The blockage of airflow causes the air conditioner freezing issue. Your air conditioner might be freezing because of one of the following issues.

• Air Filters –One of the most common reasons your AC unit may freeze is that the air filter is dirty. A dirty air filter restricts airflow and can cause the evaporator coils to freeze. If your AC unit is freezing up, check the air filter and replace it if necessary. If the problem persists, there are a few other potential causes to investigate.
• Refrigerant Leak –A refrigerant leak is another common reason for an AC unit to freeze up. When refrigerant levels are low, it can cause the evaporator coils to freeze. Have a professional technician check for leaks and repair them as necessary.
• Blower Motor –The third potential cause is a faulty blower motor. If the blower motor does not work appropriately, it will not circulate air properly and can cause the evaporator coils to freeze. Have a professional technician inspect and replace the blower motor if necessary.
• Inaccurate Setting –The fourth potential cause of an AC unit freezing up is incorrect fan speed settings. If the fan speed is too low, it won’t circulate air properly and can cause the evaporator coils to freeze. Set the fan speed to “auto” rather than “low” or “high” to let the fan run at an optimal speed.

If your AC is freezing up, acting quickly is important. Allowing the unit to run while frozen can damage the compressor and other components. To thaw a frozen AC unit, turn off the power and remove the ice with a brush or vacuum cleaner attachment. Once the ice is removed, clean or replace the air filter and check for any blockages in the airflow.

When to Call the Expert

Now, you know the potential triggers behind the air conditioners’ freezing issues. If your Air conditioner is not working adequately, diagnose your AC by following the steps,

before looking for a technician,

• Air filters – Check the air filters to see whether they are dirty. Clean or replace the air filters if you find them dirty, as dirty air filters can block the airflow, resulting in the freezing issue of air conditioners. Ensure to set up a routine for checking the air filters, as they play a key role in air conditioning your space.
• Fan Setting – Tune the fan on auto instead of high or low, as the inaccurate fan setting can be another potential issue behind your air conditioner freezing.

If your air conditioner keeps freezing up after fixing the air filters and fan settings, it’s best to call an expert for help. The professional technicians will check the blower motor, refrigerant leakage, and other potential things to diagnose the problem and get your AC running smoothly again in no time!

How to Fix a Frozen Air Conditioner

Follow the enlisted steps to fix a frozen air conditioner:

• Start by turning off the unit and letting it thaw for about an hour.
• Check the air filters of your air conditioner and clean or replace them if found dirty.
• Check the fan setting and tune it to auto mode to let the system optimize the airflow to avoid freezing.
• Inspect the blower motor, which maintains the required airflow to cool the space. Replace the blower motor if it’s not working properly.
• Check Refrigerant leakage and refrigerant level for refilling it to an appropriate level.

Helpful Tips for Preventing Freezing AC

We have enlisted expert tips to prevent air conditioners’ freezing issues.

• Air filter inspection – Set a routine for air filter inspection. Clean or replace the dirty air filters after every defined period to avoid air blockage because of dirty air filters.
• Evaporator Coils – Make sure the evaporator coils are clean. Dirty coils can also restrict airflow and cause the AC to freeze up.
• Fan mode – Ensure your air conditioner fan is always in auto mode.
• Refrigerant level – Set a routine to check the refrigerant level at least once a month to prevent ACs’ freezing because of the lower refrigerant level.
• Ventilation – Keep the area around the outdoor unit clear of debris. It will ensure proper airflow and help prevent the AC from freezing up.
