The hot and humid summers in Boiling Springs, SC mean that an effective air conditioning system is key to your comfort. Your air conditioning system has two coils, including the evaporator coil and condenser coil. The refrigerant cycles through these coils in order to complete a cooling cycle. Read on for three signs that your AC’s evaporator coil is struggling.

Constant AC Cycling

A dirty, frozen or damaged evaporator coil leads to long AC cycling times. When the evaporator coil is dirty, covered in ice, or physically damaged, it can’t absorb heat. The condenser tries to make up for it by extending the cycle time and triggering more frequent cycles. This also leads to high electricity bills. If you notice that your air conditioner is constantly running, it’s wise to call for repair services.

Lack of Cooling

Another sign of a struggling evaporator coil is a lack of cooling. You may feel warm air blowing from your home’s vents. Dirty or frozen coils aren’t able to absorb heat. The warm air just passes over the malfunctioning coil and blows back into your living spaces. Physical damage to the coil could cause the refrigerant to leak. You may hear a hissing sound if there’s an active leak. Once the refrigerant level is too low, the air conditioner will automatically shut down. When there’s no cool air blowing from your vents, it’s best to have our professional HVAC contractors take a look.

Ice Buildup or Water Leak

You might notice a buildup of ice on the evaporator coils. Frozen coils cause low airflow. The warm air passing over the ice results in melting. This could overflow the drain pan, leading to an automatic AC shutdown. According to Energy Star, frozen coils can be prevented with regular AC maintenance.
