How to fix frozen AC coils

Answering the Call for Help with Reliable Appliance & HVAC

Hey there folks! I’m the manager of Reliable Appliance & HVAC, and I’m here to cut to the chase about a common issue people call us for — AC frozen coils.

Recently, we received a call from Mr. James Johnson who lives in sunny Los Angeles, California. His central AC brand was Carrier, and he told us that he noticed issues with his AC’s cooling. He couldn’t figure out why and became frustrated when the AC would not operate even after repairs. After a detailed initial assessment, our technician, Kyle, who arrived promptly, quickly identified the issue — frozen coils.

The AC’s coils, which are responsible for removing the warm air from your home by releasing cool air, were freezing up, so no cool air was reaching Mr. Johnson’s home. Kyle informed Mr. Johnson that frozen coils happen when air or coolant doesn’t flow correctly through the coils, leading to an accumulation of condensation which freezes over the coils leading to decreased cooling.

To fix this issue, we had to take special measures to prevent future frozen coils issues. Kyle replaced the air filter that had accumulated too much dust and dirt that was preventing airflow, causing the AC to work harder and leading to the frozen coils. Our technician went ahead and gave it a deep clean and tuned up some other parts of the central AC. With some elbow grease and know-how, the AC was back in action within a few hours. Finally, we advised James on how best to maintain his AC, by scheduling regular maintenance services and replacing filters every three months on his Carrier AC.

If you find yourself with a frozen coil problem, please know that we can help! It is crucial to address the issue as quickly as possible as the constant running of your AC can lead to expensive compressor damage. To help you, we have put together an itemized table of the costs that you may incur during a service call to fix frozen coils on central AC.

The Most Effective Preventive Actions To Avoid AC Frozen Coils Issues

Are you tired of dealing with costly AC repairs every summer? Then it’s time to take preventive action to avoid AC frozen coils issues. As a leading HVAC company in San Diego, we believe that knowledge is power when it comes to preventing AC frozen coils issues, and today, we’ll guide you through the best preventive actions.

Understanding The Causes Of AC Frozen Coils Issues

To prevent AC frozen coils issues, you must first understand the common causes of the problem. One frequent root cause is a clogged air filter. An air filter that is full of dirt and dust restricts airflow and causes your AC system to work extra hard, leading to frozen coils. Another cause could be a refrigerant leak or malfunctioning thermostat. That’s why it’s critical to call an HVAC technician at the first sign of any AC issues, such as weak airflow or loud noises.

Preventive Actions To Avoid AC Frozen Coils Issues

Now that you know the causes of AC frozen coils, it’s time to take preventive action:

1. Regular AC Maintenance

Regular AC maintenance is the number one preventive action to avoid AC frozen coils issues. Manufacturers and HVAC technicians’ recommendations are to have your AC unit serviced biannually or annually, depending on your system type. During a routine maintenance visit, an HVAC technician will inspect your system, clean the coils, and replace any worn-out parts.

2. Change Air Filters Frequently

As mentioned previously, a clogged air filter is a common cause of frozen coils due to restricted airflow. When your AC system works extra hard to produce cold air, the evaporator actually becomes too cold and causes the moisture in the air to freeze on the coils. So, it’s essential to change your air filters frequently, depending on your AC usage and the air quality in your area.

3. Maintain Good Airflow

Maintaining good airflow is essential to prevent frozen coils. Keep furniture, drapes, and other objects away from your vents, and ensure that your AC unit has ample space for proper airflow. Regularly check your ductwork for leaks, which can also cause poor airflow.

4. Install A Programmable Thermostat

Installing a programmable thermostat is a great preventive measure to avoid frozen coils. A programmable thermostat will regulate your system’s temperature, ensuring that your unit doesn’t work too hard, causing it to freeze. It also helps reduce your energy bill since you can set the temperature to increase when you’re not at home.

5. Inspect Refrigerant Levels

Low refrigerant levels could cause your AC system to freeze since the refrigerant is responsible for absorbing heat inside your home. An HVAC technician will inspect your refrigerant levels and ensure that they’re adequate.


Preventing AC frozen coils issues doesn’t have to be complicated or expensive. With regular maintenance, changing your air filters, maintaining good airflow, installing a programmable thermostat, and inspecting refrigerant levels, you can avoid costly repairs and ensure that your AC unit runs efficiently all summer.

If you notice any AC issues, don’t hesitate to call Reliable Appliance & HVAC at (866) 516-1222 to schedule an appointment with one of our expert technicians. We’ll inspect your unit, provide a quote, and recommend the best preventive actions to avoid frozen coils issues.
