Keeping your air conditioner working at an optimal level during the summertime is always a top priority. However, an air conditioner can eventually freeze up due to several reasons. You may be able to troubleshoot this on your own, but there’s a good chance you’ll need to reach out to a local HVAC company for additional assistance. Here are a few of the most common reasons why your air conditioner might freeze up.

1. Low Refrigerant Level

One of the main causes of an AC freezing up is a low refrigerant level. If this is the issue, you’ll need to have the problem taken care of professionally. It can happen due to a variety of reasons, most frequently a leak. At any rate, this changes the pressure within your HVAC system. Over time, the moisture will freeze on the coils and create ice that limits your airflow. Contacting an HVAC company to check your refrigerant level is always a good idea.

2. Not Enough Airflow

Inadequate airflow is another common reason why air conditioners tend to freeze up. Replacing your air filters every few months is a great way to stay proactive and avoid this problem. However, the airflow restriction may be due to an obstruction in your ductwork. An HVAC technician can inspect your system to identify the source of the problem.

3. Unclean Coils

Dirty coils can also cause problems with your air conditioner. These coils can eventually become waterlogged and freeze due to an overflowing drip plan. The layer of dirt on the surface of the coils can also make it difficult to absorb water, which results in freezing issues. Scheduling an annual AC tune-up is a great way to stay proactive and prevent dirt from building up on your coils.
