Hello Sandesh, I saw you were asking about the reason behind the air conditioner frozen pipe outside. The main reason for this is the evaporator coils. They get too cold and the AC starts freezing. Let me expand on this below.

Who Did AC Pipe Frozen Outside?

The evaporator coils of your AC are filled with refrigerant, which cools the air in your HVAC system. The evaporator absorbs heat from the air and provides cooling in the space. 

However, when the AC undergoes a problem, the heat exchange process is interrupted, leading to ice formation on the coils. This ice goes on to accumulate on the refrigerant lines. 

I am also sharing some other known reasons behind the freezing of the AC pipe.

  1. Failure of the blower fan

  2. The leaking of refrigerant from the evaporator coil

This is all I have to share with you regarding ice on air conditioner pipe outside. I hope you now know the reasons behind this issue with your AC.

I had a problem with my air conditioning system last summer where it stopped providing cold air all of a sudden. I thus hired an AC technician to fix it, and upon more inspection, he informed me that my AC pipes were frozen. I asked him why do AC pipes freeze. He told me that a number of factors might cause air conditioner pipes to freeze, including a dirty evaporator coil, a malfunctioning blower fan, unclean air filters and so on. 

Read on to get the multiple reasons for pipes freezing on AC unit.

Why My AC Pipe is Frozen?

The AC technician informed me of the following reasons:

  • Dirty Air Filter

A clogged filter is a common cause of air conditioner pipe frozen. This leads to inadequate ventilation. The temperature inside the pipes may decrease to the point that condensation freezes and obstructs the flow of air and causes the evaporator coil to freeze.

  • Damaged Blower Fan

The warm air cannot reach the condenser coil through a damaged fan, which could lead to the coil freezing.

  • Dirty Evaporator Coil

An unclean evaporator coil will also hinder appropriate air movement, just as dirt might clog the air filter and lead to issues.

  • Low Refrigerant

The cooling process depends on refrigerant. If there isn't enough of it flowing through the system, the pipes may freeze as a result of the system's temperature dropping too low.

  • Blocked Supply or Return Vents

An obstruction in the supply or return vents of your air conditioning equipment can also lead to the freezing of your AC pipe.

To fix these problems, you must get your AC maintenance and cleaning done on a regular basis. You can hire an AC Technician directly from NoBroker.
