Ac Unit Evaporator Coil Freezing Up

This happens because the refrigerant in the evaporator coils can no longer absorb the heat needed for the coils to warm up.

Ac unit evaporator coil freezing up.

Normally this isn t a problem because the condensation droplets fall off the coils into the drip pan. It is also a recipe for several other unpleasant problems with your ac like dirty sock syndrome. Check your evaporator coil if your air conditioner is freezing up. Broken fans can impede air flow and cause coils to freeze.

The reason your evaporator coils can freeze is that in addition to cooling the air inside your home air conditioners also dehumidify it. A dirty evaporator coil the inside one can cause a lack of airflow across it dropping the temperature and causing your air conditioner to freeze up. You can detect this when you notice frost on the copper tubing of the unit or on other components of the ac. When the refrigerant inside a central air conditioning unit falls below 32 degrees fahrenheit humidity that surrounds the coils freezes.

The next thing you know you have frozen ac coils freeze. Dirty air filters can cause frozen ac coils. In order to keep the air flow in your own house moving enough to not disrupt your air conditioner s functionality you need to be sure your air filters aren t dirty and becoming clogged. They pull the water out of the air which makes condensation that builds up on the coils.

If the temperature of the evaporator coils falls below 32 degrees water vapor in the air surrounding the coils will begin to freeze when it comes into contact with the coils. The coils become encased in ice and the air conditioning. One of the common ac problems is the unit freezing up. When you experience a freezing air conditioner it is important to determine what is causing it.

If anything blocks air from flowing over the coil it gets too cold and ices up. The more the refrigerant has to expand the cooler it makes the temperature. Insufficient airflow is often responsible for an air conditioner freezing up. At first there may be only a thin film of ice or frost but over time a large coating of ice can build up.

If your air conditioner is running low on refrigerant due to a possible leak it can freeze up. Your ac needs clear air flow throughout in order to function properly. When your home s airflow is restricted there is no air moving through the system to keep condensation from building on the evaporator coil. If air is not circulating around the coils the coils get too cold.

Dirty filters can obstruct the air from getting in and out.
