Poor Airflow
A frozen evaporator coil can cause a lot of problems for your air conditioner and home. Poor airflow is a problem that can lead to a frozen evaporator coil, or be the result of a frozen evaporator coil. Let’s explain.
If there’s not enough airflow coming into the system, ice can develop on the evaporator coil since it doesn’t have enough air to cool down. However, if something else is causing a frozen evaporator coil, the ice can actually block airflow from that point of the system out to your home.
Clogged Condensate Drain
A clog in your condensate drain line can also cause a frozen evaporator coil. The condensate drain line is how moisture from the air gets channeled outside and away from your home. A clog in the line can cause this moisture to back up into the system and contribute to a frozen evaporator coil.
Dirty Air Filter
When we talk about airflow into the system, the first place we check is your air filter. If you don’t change your AC’s air filter every 1-3 months, it can easily get clogged with dust and dirt. A clogged filter cannot let as much air through and into the system.
Your AC has to work harder in an effort to bring in more airflow. Meanwhile, the evaporator coil is developing ice because it doesn’t have enough air to cool. You may be able to prevent a frozen evaporator coil simply by changing your air filter regularly.
Low Fan Speed
If the fan inside the AC is spinning too slowly, it’s not moving air over the evaporator coil fast enough. As a result, the coil may develop ice and stop being able to cool your home as well. You may not even realize that this is the problem. It takes our team of expert technicians to troubleshoot and find the source of the problem sometimes. The good news is, once we figure it out we can talk to you and give you tips for preventing the problem in the future.
Dirty Condenser Coil
Your air conditioner actually has two sets of coils. The evaporator coil is located inside your house, while the condenser coil is located outside your house. If the condenser coil gets too dirty, it can block heat and humidity from being able to channel outside of your home. When this happens, it can impact how well your evaporator coil works inside of your home, even leading to ice buildup.
Sometimes, homeowners think that an icy evaporator coil is a good sign because it means extra cooling. But when that ice melts, it could cause water damage inside your home. Plus, an icy evaporator coil actually has the opposite effect. Ice can block cooling, leading to your home being too warm and humid.
