A frozen evaporator coil can cause your HVAC system to lose efficiency, reduce airflow, and even lead to system failure. At RYN Services LLC, we provide expert frozen evaporator coil diagnosis, repair, and preventive maintenance to restore your cooling system’s performance and prevent costly breakdowns. If your air conditioner is blowing warm air, icing over, or not functioning properly, our skilled technicians are here to help.

What Causes Frozen Evaporator Coils?

• Restricted Airflow – Dirty air filters, blocked vents, or clogged ducts reduce airflow, causing the coils to freeze.
• Low Refrigerant Levels – Leaks or low refrigerant levels can cause the system to overwork, leading to ice buildup.
• Dirty Evaporator Coils – Dust and debris on the coils can prevent proper heat absorption, leading to freezing.
• Malfunctioning Blower Fan – If the blower fan isn’t running at full capacity, it can restrict airflow and contribute to freezing.
• Thermostat Issues – A faulty or miscalibrated thermostat may cause the system to run continuously, increasing the risk of coil freezing.
• Drainage Problems – A clogged condensate drain line can cause excess moisture buildup, contributing to ice formation.

Signs Your Evaporator Coil is Frozen

• Weak or no airflow from vents.
• AC unit blowing warm air despite being set to cool.
• Visible ice buildup on the indoor AC unit or refrigerant lines.
• Excessive condensation around the air handler.
• Higher energy bills due to an overworked system.
• Frequent system cycling or unexpected AC shutdowns.
