Your air conditioning (AC) system is a complex piece of machinery that plays a crucial role in keeping your home comfortable during the hot summer months. At the heart of this system are the AC coils, which are responsible for absorbing heat from the air and transferring it outside. These coils, both the indoor evaporator coil and the outdoor condenser coil, work together to create the cooling effect that you enjoy in your home.

The evaporator coil is located inside your home, typically in the air handler or furnace, and it absorbs heat from the air as it passes over the coil. This heat is then transferred to the refrigerant, which is circulated through the system. The outdoor condenser coil, on the other hand, is located outside and is responsible for releasing the absorbed heat to the outside air, allowing the refrigerant to cool down and repeat the cycle.

Understanding the importance of these coils and their functions is essential for maintaining the efficiency and longevity of your AC system. Below, we are going to explain why AC coils sometime freeze, and why you should have this situation addressed by a professional air conditioning company in Riverwoods, Illinois.

Common Causes of Frozen AC Coils

One of the most common issues that can arise with your AC system is the freezing of the coils. This can happen for a variety of reasons, and it’s important to address the problem quickly to prevent further damage to your system.

1. Lack of Airflow: Insufficient airflow over the coils can lead to a buildup of frost and eventual freezing. This can be caused by a clogged air filter, a blocked return duct, or even a malfunctioning blower fan.
2. Refrigerant Leaks: If your AC system is low on refrigerant, it can cause the coils to freeze as the refrigerant is unable to absorb enough heat from the air.
3. Thermostat Issues: A malfunctioning thermostat can also lead to frozen coils, as it may cause the AC system to run for too long or at an inappropriate temperature setting.
4. Outdoor Conditions: Extremely hot and humid outdoor conditions can also contribute to the freezing of the coils, as the system will be forced to work harder to maintain the desired indoor temperature.

Identifying the root cause of the frozen coils is crucial for finding a long-term solution and preventing the issue from recurring.

Signs and Symptoms of Frozen AC Coils

Recognizing the signs and symptoms of frozen AC coils can help you address the problem quickly and prevent further damage to your system. Here are some common indicators that your coils may be frozen:

• Reduced Airflow: If you notice a significant decrease in the amount of air coming from your vents, it could be a sign that the coils are frozen and restricting airflow.
• Icy Coils: Visually inspecting the coils, both indoor and outdoor, and seeing a buildup of ice or frost is a clear indication of a frozen coil.
• Warm Air: If your AC system is blowing warm air instead of cool air, it’s a strong sign that the coils are frozen and unable to effectively cool the air.
• Increased Humidity: Frozen coils can cause an increase in indoor humidity levels, as the system is unable to properly dehumidify the air.
• Unusual Noises: As the ice on the coils expands, it can cause unusual noises, such as rattling or banging, from the AC unit.

If you notice any of these signs, it’s important to act quickly to address the issue and hire a professional air conditioning company in Riverwoods, Illinois.
