As the temperatures rise in Charlottesville, Virginia, the last thing you want is your air conditioner freezing up. Ironically, that cold frost on your AC unit isn’t a sign of extra cooling power but a warning bell that something’s amiss. In this guide, brought to you by The Otter Guys, we’ll explore why your air conditioner might be freezing up and what you can do about it.

What Does It Mean When an Air Conditioner Freezes Up?

If you notice ice on the coils of your AC unit, it means that the system isn’t operating as it should. Though it might look fascinating, it’s a clear sign of trouble that needs immediate attention.

Common Reasons for Freezing

Here are some of the common causes of an air conditioner freezing:

• Restricted airflow – When airflow is limited, it can cause the coils to freeze. Common culprits are dirty or clogged air filters, closed or blocked vents, and problems with the fan.
• Low refrigerant levels – Low refrigerant can cause the coils to get too cold and freeze. This usually happens if there’s a leak somewhere in the system.
• Running the AC at night – Charlottesville nights can get pretty cool, and running your AC during low temperatures can lead to freezing.
• Mechanical failures – Any malfunctioning parts, such as valves or controls, can cause freezing. This often requires professional intervention.

It’s important to understand these causes so you can avoid them.

How to Prevent Your Air Conditioner from Freezing Up

Here are some of the ways you can prevent your air conditioner from freezing up:

• Regularly change the air filters –  Ensure that the filters are clean and changed as needed. It helps in maintaining smooth airflow.
• Keep the vents open and unblocked – Don’t close too many vents, and make sure they’re not obstructed by furniture or curtains.
• Monitor refrigerant levels – If you suspect a leak, it’s time to call in the professionals like The Otter Guys.
• Don’t run the AC in cold weather – If it’s cool enough outside, consider turning off the AC to prevent freezing.

While these fixes don’t guarantee your air conditioner will remain unfrozen, they will help significantly. 

What to Do If Your Air Conditioner Freezes Up?

1. Turn Off the System

If you notice ice, shut down the system to allow it to thaw.

2. Check the Air Filters and Vents

Inspect these areas to see if they might be causing the problem.

3. Call a Professional if Needed

Sometimes, DIY isn’t enough. If the problem persists or you suspect a refrigerant leak, it’s best to call in the pros.
