More about Ice formation on AC
are the reasons behind “Ice formation on AC” problem?
Ice formation on
an air conditioner is a common problem. When ice or frost builds up on your AC
unit, cooling process gets effected. In worse cases an air conditioner stops cooling
3 most common
reasons behind the problem of ice formation on AC are:
These are some common reasons behind ice formation on AC problem but there can be other reasons as well.
- Dirty air filter: The most common
cause of ice formation on AC is a dirty air filter. Dust and dirt on air filter
of your air conditioner hamper airflow over the cooling coils or evaporator
coils. Constant air flow inside your AC maintains the temperature of the
cooling coil above freezing point. But when this air flow gets restricted by
the clogged air filter, the cooling coil gets too cold. This phenomena later
causes the moisture in the room to condense on the coil and freeze. The frost
developed over the coil further reduces the airflow and eventually the AC stops
cooling completely. To prevent this problem of ice formation on AC, clean the
air filter of your AC from time to time.
- Insufficient coolant level: When the level
of coolant (Freon) is less than the required amount, the temperature of cooling
coil drops much below the normal. Due to this phenomena the moisture in the
room condenses on the coil and freezes. An AC repair professional will be able
to accurately determine if the refrigerant level is just right in the cooling
- Faulty evaporator fan: Another common
cause of ice formation on AC is a faulty evaporator fan. The evaporator fan
constantly blows air inside the AC unit and keeps the temperature of cooling
coils above the freezing point. This prevents frost formation on coils. But a
faulty fan allows the temperature of cooling coils to drop much below the
freezing point causing room moisture to condense and convert into frost on the

The PRO visits
clients site and troubleshoots the problem of ice formation on AC. The PRO
first looks for basic reasons like clogged air filter and dirty cooling coil.
If the filter and coils are found clean then PRO checks the key components of
the AC like compressor, condenser, coolant, thermostat, start capacitor, sensor
and others. After the actual problem is identified, PRO describes the problem
to the customer and suggests a possible repair or replacement. On customer
consent, the PRO repairs the AC.
