The answer to 'why is my AC freezing up in summer' is that there are several common causes, including low refrigerant levels, a dirty air filter, or a problem with the compressor or fan. When an AC system freezes up, it can lead to reduced cooling and even complete system failure.
Some of the most common symptoms of a freezing AC include ice buildup on the coils, reduced airflow, and the system cycling on and off frequently. In many cases, the issue can be resolved by addressing simple maintenance tasks like changing the air filter or cleaning the coils. However, if the problem is caused by a more serious issue like a refrigerant leak or compressor failure, it's best to call in a professional HVAC technician to diagnose and repair the problem.
