CAUSES OF ICE BUILDUP

It is important for your air conditioner to have enough airflow and refrigerant for the air-conditioning process to take place correctly. A lack of airflow caused by an obstruction in the air conditioner or a blower-fan motor failure is a common cause of ice buildup on the coils in the following ways:

A completely clogged air filter can block incoming air from reaching the evaporator coil while leaves and yard debris can do the same for the condenser coil.

An indoor or outdoor blower-fan motor failure can prevent either fan from working, starving the air conditioner of the airflow it needs to properly operate.

Ice buildup can also happen due to low refrigerant levels caused leaks or improper refrigerant charging. Low refrigerant levels often mean low operating pressures, which in turn lower the temperature of the refrigerant.

You’re probably wondering how you can tell whether your air conditioner is affected by ice buildup.

Common symptoms to look out for

1. Presence of ice buildup on the indoor or outdoor cabinet 2. Inability to effectively cool indoor spaces. 3. Constant short-cycling 4. Spilled water from melting ice.

Here are some ways how to prevent ice buildup

PREVENTION OF ICE BUILDUP

The first thing you’ll want to do when encountering ice buildup on your air conditioner is to simply shut off the unit and let the ice thaw for a few hours. You can use a hair dryer on its highest setting to speed the process along. Don’t attempt to remove the ice by hacking away at it with an ice pick or other sharp object, as this could damage your evaporator or condenser coil.

Afterward, you should check your air filter and make sure it isn’t completely blocked with dust and debris. If the filter is clogged, remove it and put a new one in its place. Your air filter should be changed at least once every three months to keep clogs from forming.Chemical service is a must twice every year or at least once to maintain cooling efficiency of your system.

If the air filter is clog free, have your technician take a quick look at the blower-fan motor. Your technician will make sure the motor is properly working and repair any issues that could prevent it from doing so, including overheating due to dust and debris buildup, a blown relay, or wiring issues.

Last but not least, you should have your technician check the refrigerant levels as well as the actual evaporator and condenser coils. Depending on the circumstances, your technician may need to add more refrigerant to the unit as well as repair any leaks found throughout the system.
