How Ice on Your Air Conditioner can Cause a Complete Breakdown

You may think that ice on your air conditioner is a good sign. After all, the system is supposed to be cold, right? Actually, as counterintuitive as it may seem, ice on your air conditioner is a very bad sign. In fact, if not treated right away, it can cause the entire system to break down. Read on to find out more about why ice forms on your air conditioner in the first place, the damage it can cause, and what to do about it.

Why Ice Forms on Your Air Conditioner

Ice begins to form on the air conditioner when the evaporator coil malfunctions, typically because it has been cut off from its air supply. This tends to happen when the coil is covered in dirt, or when the air filter becomes clogged due to infrequent cleanings. When that happens, the evaporator coil freezes the condensate that collects on it during operation, forming ice.

Why It’s Bad

For one thing, the weight of the ice can permanently warp the coil if it’s allowed to build up far enough. Replacing an evaporator coil is typically not cheap. Aside from that, the ice can travel down the siphon line and cause the compressor to freeze, which is even worse. Without an operating compressor, the entire system can’t function.

How to Prevent It

The best way to prevent your air conditioner from icing up is to have it inspected by an HVAC professional at least once a year. One of the first things your air conditioning technician will do is check and clean the air filter for the evaporator coil, which will make sure that the coil remains clean and ice free.
