Why Is There Ice on My AC?

Seeing ice buildup on certain parts of your air conditioning system may seem normal, especially if you feel the area that is covered in ice, because it will be very cold. But we can tell you without hesitation that this isn’t normal and is indicative of one of several problems with your air conditioning system. Scraping off the ice does not fix the problem because the ice is a symptom of the problem, not the problem itself. So what can cause ice to build on your air conditioner? Let’s take a look.

A Clogged Air Filter

It may seem like a big problem for a small thing like a dirty air filter, but a dirty air filter can cause a lot of problems with your system. If ice has formed on certain parts of your system, this is usually indicative of an air flow problem, which is common with clogged air filters. This is because once the air filter has become thoroughly clogged, air can no longer pass through it, seriously restricting your air conditioner’s air flow.

Problems with a Fan

There are two fans in your air conditioning system and both are important contributors to your system’s air flow. When either fan develops an issue that can affect its operation, such as a worn fan belt or motor issues, the air flow in your system will suffer. When your air flow is imbalanced, your AC can’t release heat or cool properly, leading to an ice build-up.

Refrigerant Leak

The refrigerant in your system is responsible for facilitating the transfer of heat. Your air conditioner needs an exact amount of refrigerant in the system at all times to transfer heat properly. Leaks lower the amount of refrigerant in your system, which directly affects the ability of the system to properly transfer the heat. This results in an ice build-up.
