Common Causes and When to Call for Help

Seeing ice on your air conditioner during the hot summer months might seem strange, but it’s a fairly common issue that can signal problems needing prompt attention. Here’s what causes it and what you should do.

❄️ What Causes Ice on Your AC?

• Low Refrigerant Levels
  Refrigerant leaks reduce pressure in the system, causing evaporator coils to get too cold and freeze moisture on contact.

• Restricted Airflow
  Dirty air filters, blocked vents, or malfunctioning blower fans can limit airflow over the coils, causing them to freeze.

• Thermostat Issues
  Incorrect thermostat settings or faulty sensors may cause the AC to run continuously, lowering coil temperatures excessively.

• Dirty Coils
  Grime buildup on evaporator coils insulates them, preventing heat absorption and causing freezing.

• Outdoor Temperature and Humidity
  Running the AC when outdoor temps are unusually low or high humidity levels can sometimes contribute to icing.

⚠️ Why Is This a Problem?

Ice on your AC blocks airflow and reduces cooling efficiency. If left unchecked, it can damage compressor components, lead to costly repairs, or cause your system to stop working altogether.

🛠️ What Should You Do?

• Turn off the AC to let the ice melt.

• Check and replace dirty air filters.

• Ensure vents and registers are unobstructed.

• Schedule a professional HVAC inspection to check refrigerant levels and system health.
