Addressing Frozen Coils in Central Air Conditioners | AirGreen Montreal

In the heart of Montreal’s sweltering summer, there's nothing more refreshing than a properly functioning central air conditioner. Yet, like all machines, these systems can sometimes encounter issues. One problem often reported by homeowners is frozen or iced-up coils. This is a clear sign of an issue requiring immediate attention. AirGreen, a leading HVAC provider in Montreal, is here to guide you through the causes and solutions to this prevalent problem.

Airflow Problems

The most common reason for a central air conditioner to have iced-up coils is due to inadequate airflow. The flow of air across the evaporator coils is crucial in the refrigeration cycle, absorbing heat from your indoor air and moving it outside. Any issues such as clogged filters, blocked vents, or malfunctioning fans can significantly hinder this process, causing the coils to freeze.

Clogged filters are notorious for causing airflow issues in central air conditioners. They restrict the amount of air that can flow across the evaporator coil, causing it to cool excessively and freeze. Regular replacement or cleaning of filters can help prevent this problem.

Similarly, blocked vents can impede airflow. The vents should be clear of any obstructions for the air to flow freely. Regular checks of the vent system can ensure there are no blockages.

A malfunctioning fan can also impede airflow. The fan in your central air conditioner is responsible for drawing in warm air from your home and across the evaporator coil. If this fan isn't working as efficiently as it should, it may result in reduced airflow, causing the coils to freeze.

AirGreen’s comprehensive HVAC services in Montreal include a detailed assessment of airflow issues, ensuring your central air conditioner is performing optimally and free of ice-ups.

Low Refrigerant Levels

Another cause for frozen coils can be low refrigerant levels. The refrigerant, or coolant, absorbs heat from your indoor air and releases it outside. If the refrigerant levels are low, the evaporator coil can become too cold, causing moisture from the indoor air to freeze upon contact.

A professional HVAC company, like AirGreen, can check your central air conditioner's refrigerant levels and top them up if necessary, ensuring smooth and efficient operation.

Faulty Defrost Cycle

In certain cases, a faulty defrost cycle can lead to frozen coils in your central air conditioner. A functional defrost cycle ensures that any ice or frost build-up on the coils is periodically melted to prevent freezing. A malfunction in this cycle could lead to continual ice build-up.

AirGreen's expert HVAC services include an assessment of your central air conditioner's defrost cycle, ensuring it's functioning as it should and preventing potential ice-ups.

In conclusion

An iced-up central air conditioner needs swift attention to prevent further complications. AirGreen is dedicated to providing top-quality HVAC services in Montreal, from rectifying airflow issues to managing refrigerant levels and ensuring the correct functioning of the defrost cycle, promising you a cool and comfortable summer.
