Finding ice on your air conditioner
during a hot summer day is a serious problem, so learn why you have a frozen evaporator coil in
Baltimore or why your AC is freezing up and how to fix it immediately. When it is 95 degrees
outside, a thick layer of ice building up on your indoor AC unit or outdoor copper lines will cause
the system to blow warm air and can severely damage the compressor. Common causes include
restricted airflow, where a severely clogged air filter or blocked return vents choke the system
and prevent warm air from keeping condensation from freezing. Another cause is low
refrigerant due to a leak, which drops the pressure and causes the remaining refrigerant to
become too cold, or dirty evaporator coils that act as an insulator and prevent the absorption of
heat. If this happens, turn the thermostat to off and the fan setting to on to force warm air over
the ice to melt it, then check your air filter; if it is clean, you likely have a refrigerant leak and
should call Five Star HVAC at +1 (240) 210-7032 for emergency repairs.
