Frozen coils are never good because it means that the refrigerant is leaking. There are a few reasons why this is happening, and we can help!
Have you noticed that your home doesn’t get cool enough no matter how low you turn down your AC? If this describes your case, it’s not global warming; it’s your AC coils. Your AC coils hold the refrigerant, a unique liquid responsible for cooling your home. The AC coils absorb heat from inside the house, dispel it outside, and repeat the process until your home is sufficiently cool.
6 Common Causes
Frozen coils are never good news because it means the refrigerant is leaking. There are many reasons why your AC coils are frozen. But, regardless of the reasons, the consequences always remain the same; a highly inefficient AC.
Here are a few reasons for frozen AC coils. That way, you can take the necessary measures to keep your AC oils from freezing. So, without wasting much time, let’s dive straight into it.
- Dirty Air Filters – You must replace your air filters at least every three months. Dirty air filters are among the leading causes of frozen AC coils. Remember, your AC needs a steady supply of air to function correctly. Dirt and debris that clogs the filters may hinder sufficient airflow. This hinders enough air from getting to the AC coils. Unfortunately, this means the coils get too cold and eventually freeze.
- The AC Fans Are Broken or Don’t Work – Fans are a crucial component of your AC unit. The fans are what push the air towards the coil for cooling. However, when the fans break, they cannot push the air to the coils. This means the coils don’t get sufficient air, so they freeze.
- The AC Coils Are Dirty – Apart from dirty filters, dirty evaporator coils are also a serious problem. When dust and debris accumulate around the coils, they hinder their ability to dispel and absorb heat from the environment. This leads to humidity condensation, which eventually freezes on the coils.
- It’s Too Cold Outside – There are instances when the temperature outside is too cold. In such cases, the air won’t have sufficient heat for the coils to absorb and keep them from freezing. This is one cause that is beyond your control.
- The Drain-pipe is Clogged – It’s normal for condensation to form on the AC coils. This condensation drains through the drainpipe to the outside. The condensation will have nowhere to go if the drain pipes are clogged. In this case, the condensation clings to the AC coils and freezes.
- Refrigerant Problems – Ensure your AC coils have enough refrigerant to function correctly. Not having enough refrigerant in the coils will make your AC overwork. When this happens, the condensation on the coils is likely to freeze instead of draining through the drainpipe.
