Causes Of Evaporator Coils Frozen

Causes Of Evaporator Coils Frozen

Your air conditioner works hard throughout summer to keep your home cool and comfortable. Unfortunately, even the most well-fitted, durable air conditioner can have difficulty operating correctly throughout the summer months. Evaporator coils frozen can be a huge problem if your air conditioner stops working, especially if it’s in the middle of a hot summer day. If the coil is frozen, the air conditioning unit can’t do its job, and your house will be warmer than usual.

Causes of evaporator coils frozen

 

1. Low refrigerant level

Low refrigeration levels lead to a frozen air conditioner. When this occurs, there’s a drop in pressure inside the evaporator coil, which causes moisture to accumulate and freeze up. If your air conditioner unit is experiencing low refrigerant levels, contact an HVAC professional immediately.

2. High humidity levels 

The air in your room might be oversaturated above the moisture levels your air conditioner can take, which causes increased condensation to pool around your evaporator coils and freeze as the cold air lowers the temperature. Humid weather, rains, and humidifiers are common reasons for high moisture in the air.

3. Drainage problems lead to evaporator coils being frozen

Especially in humid climates, your evaporator coil will have to work more to eliminate all that humidity in the air. When the humidity is removed, condensation forms and is drained away from your house. It is okay, except when you have a clogged drainpipe, which ultimately causes the water to back up and freeze on your evaporator coils.

4. Low outdoor temperature

If the air temperature in your house is already low, the air conditioner evaporator coil can freeze. For example, it may happen in case the air conditioner runs excessively during the night. It is because the coil absorbs the hot air outside and turns it into a cold one that circulates in the home, but the lack of heat in the air can lead to frozen coils.

5. Blocked air ducts

If you’ve manually shut many of your home’s floor or ceiling registers, the return airflow to the coil may not be getting sufficient airflow to continue operating correctly. Another common cause of this problem is when homeowners unknowingly block floor registers below furniture or rugs. 

6. Inadequate system airflow

Lack of system airflow is one of the most common causes of evaporator coils frozen. It can be from closed-off air registers to malfunctioning air handlers. If there isn’t enough air blowing over your evaporator coil, the coil won’t have enough heat to absorb. As a result, it will cause the condensation on the coil to freeze over.

Why are evaporator coils leaking?

When your HVAC system turns on, it should immediately blow cold air through the vents. But if the airflow feels weak or lags when your system turns on, it must be a sign of the evaporator coil leaking
