Why is there ice on my air conditioner?

Direct answer

Ice commonly indicates that the indoor coil is too cold because of restricted airflow, low refrigerant conditions or another operating problem.

What this usually means

Turn cooling off and allow the system to thaw. Running a frozen system can worsen water problems and does not correct the cause.

A technician may need to evaluate airflow, filters, blower operation, coil condition and the refrigerant circuit.

What you can safely check

  • Turn cooling off
  • Check the filter
  • Protect the area from thawing water
  • Do not chip ice from the equipment
When to call a professional

Request service if ice returns, airflow is weak or water is collecting around the equipment.
