Stop the cycle of frozen air conditioning lines

It seems like a phenomenon the first time it happens – it’s 100 degrees outside, and your air conditioner is frozen. How does this happen? How is it possible? While it does seem strange, we assure you, it’s very real, and it’s very fixable. Additionally, you’ll want to keep this from happening during the potential extreme temperature highs in the Midwest. Edwardsville, IL residents rely on their air conditioning units during how summers in the Metro-East area, and a frozen air conditioner will render your system useless. Here’s how you can rectify the situation and keep it from happening in the future.

Why do air conditioners freeze?

Due to a variety of factors, air conditioners freeze because of constant blowing of cool air over the coils. This freezes the refrigerant in your lines and stops the air conditioner from doing its job.

Why does this happen?

This happens because airflow is being restricted somewhere in the system. Whether it’s a clogged air filter or dirty evaporator coils, there’s a reason that your unit is blowing cool air nonstop. It could also be an incorrect thermostat setting – always make sure the fan setting is set to “auto.”

How do I fix it?

The easiest way to fix this problem may make you uncomfortable. You have to turn the unit off and let it thaw out completely. This may be a daunting task on a hot summer day, but it’s the only way.

While you’re doing this, you may want to find the cause of the restricted airflow and rectify the situation. Whether it’s a dirty air filter or you need to call a professional to find the cause, it’s the best way to keep it from happening again.

How do I prevent it?

Preventing this problem is actually the easy part. If you regularly inspect and change the air filter and receive an annual clean and check from your local pro, your air conditioning unit shouldn’t have this problem. This is a problem that we usually see with neglected systems.
