Join our email newsletter list and we’ll send you a coupon for 10% off your AC repair. An evaporator coil, a group of copper tubes, freezes when the refrigerant flowing through the tubes gets too cold, causing the moisture in the surrounding air to freeze. A central AC evaporator coil.
Is it possible for an air conditioner to freeze up?
However, this is not possible when your air conditioning runs into problems. One of the common AC problems is the unit freezing up. You can detect this when you notice frost on the copper tubing of the unit or on other components of the AC.
Why is my air conditioner turning into ice?
When a dirty air filter restricts airflow, there’s not enough air passing through the system to transfer heat from your home to the refrigerant.

What causes the refrigerant line on my AC to freeze?
The ice can eventually accumulate on the refrigerant line. Some common reasons that cause your AC lines to freeze are: Refrigerant leaks from evaporator coils; Accumulation of dirt over the coils; Blocked AC vents; Clogged air filters; Blower fan failure; Collapsed air ducts; Low refrigerant levels; Simple and Quick Ways To Eliminate AC Freezing
Why is my AC line covered in ice?
But sometimes, we find AC lines that are covered in ice. Why are your AC lines freezing, and what should you do to fix it? There are two basic reasons why your AC may be frozen: restricted airflow and low refrigerant. These can happen to both central and split systems.
What to do if your air conditioner is freezing?

What to do if your dryer line freezes?
Recover the refrigerant from the system and make any necessary repairs to parts such as O-rings, hoses, lines or evaporators. If the system has been opened for more than a few hours from an accident, damage or corrosion, the receiver-dryer absolutely must be replaced. It can become saturated when left exposed to the air.
