Insufficient Airflow
One of the most common causes of frozen AC coils is insufficient airflow. The evaporator coil is based totally on a normal waft of heat air from your own home to function nicely. If this airflow is restrained, the coil’s temperature can drop beneath freezing, inflicting the condensation on it to freeze.
Causes of Insufficient Airflow:
- Dirty Air Filters: When air filters are clogged with dirt and debris, they limit the go with the flow of air to the evaporator coil, causing it to freeze. Regularly converting or cleansing your air filters can prevent this problem.
- Blocked Vents: Furniture, drapes, or different gadgets blocking off the vents in your private home can restrict airflow and result in frozen coils. Ensure that every one vents are clean and unobstructed.
- Blower Fan Issues: If the blower fan that circulates air over the evaporator coil is malfunctioning, it can reduce airflow and cause the coil to freeze. An AC Company in Pearland can diagnose and repair any issues with the blower fan.
Low Refrigerant Levels
Another commonplace purpose of frozen AC coils is low refrigerant degrees. The refrigerant is responsible for soaking up warm temperatures from your property’s air, and if there isn’t always enough of it, the evaporator coil can end up too cold and freeze over.
Causes of Low Refrigerant Levels:
- Refrigerant Leaks: Over time, the refrigerant traces to your AC device can increase leaks, main to a lack of refrigerant. These leaks need to be repaired via the usage of an authorized technician, who can also recharge the tool with the outstanding quantity of refrigerant.
- Improper Installation: If your AC unit turns out to be now not properly installed, it can no longer have been charged with the ideal quantity of refrigerant. This difficulty can cause frozen coils and decreased cooling general performance. An expert setup ensures the right refrigerant degrees and fantastic overall performance.
Dirty Evaporator Coils
Dirty evaporator coils can also contribute to freezing. When dust and debris arrive at the coils, it acts as an insulating layer. Also stops the coil from soaking up warm temperatures efficaciously. As a result, the coil’s temperature can drop, causing the moisture on it to freeze.
Causes of Dirty Evaporator Coils:
- Lack of Maintenance: Regular maintenance is essential for keeping your AC unit in a suitable jogging scenario. If the evaporator coils aren’t wiped smooth frequently, they may emerge as dirty and result in freezing troubles.
- Outdoor Debris: Leaves, dust, and one-of-a-kind particles can collect throughout the outside unit, making their way into the gadget and onto the coils. Keeping the location around your outdoor unit easy can help prevent this.
Thermostat Issues
Your thermostat performs a crucial characteristic in regulating the temperature of your own home.

- Keep Vents and Coils Clean: Make sure all vents in your home are easy and unobstructed to permit correct airflow. Additionally, keep the area around your outside unit free of particles, and characteristic your evaporator coils wiped clean regularly to prevent dirt buildup.
Additional Way to Prevent
- Monitor Refrigerant Levels: Low refrigerant levels can result in frozen coils and decreased cooling overall performance. If you are aware that your AC isn’t cooling as effectively as it ought to, or if you concentrate a hissing sound from the unit, you may have a refrigerant leak. Contact a professional technician to investigate and recharge the machine if essential.
