Why is my home AC unit freezing up and how can I prevent it from happening?

Your home AC unit may be freezing up due to restricted airflow, low refrigerant levels, or a dirty air filter. To prevent this from happening, make sure to regularly change the air filter, keep the coils clean, and ensure proper airflow by keeping vents unobstructed. Additionally, have a professional inspect and maintain your AC unit regularly to address any potential issues.
