Ice Usually Means Airflow or Refrigerant Trouble

An air conditioner can freeze even during hot weather when the evaporator coil becomes too cold. This usually happens because the system cannot move enough warm air across the coil or because refrigerant levels are not correct.

Turn the System Off Before Damage Spreads

Running a frozen system can strain the compressor and lead to more expensive repairs. If you notice ice, shut the cooling mode off and call an HVAC professional to inspect the cause.

Common causes include:

• Dirty air filters

• Blocked return airflow

• Low refrigerant

• Blower motor problems

A professional inspection can confirm the source of the freeze-up and help prevent the same issue from returning.
