The answer to 'installation freezing up' is that a frozen HVAC system is a common issue that can be caused by a variety of factors, including low refrigerant levels, blocked airflow, or a malfunctioning component. Symptoms may include ice buildup on the outdoor unit, poor airflow, and reduced cooling performance.
Some potential solutions include cleaning or replacing the air filter, clearing any debris or obstructions around the outdoor unit, and checking the refrigerant levels. However, it's important to note that HVAC system repairs often require the expertise of a professional technician, especially when dealing with refrigerant-related issues. Attempting DIY repairs on a frozen HVAC system can be dangerous and may cause further damage to the system.
