What To Do When HVAC Freezes Up In Summer. As temperatures soar in Texas during hot summer months, people rely more and more on air conditioning systems. However, it can be frustrating when your heating, ventilation, and air conditioning (HVAC) unit suddenly freezes up, leaving you sweltering in the heat. If you find yourself in this situation, you’ll want to be prepared for any air conditioner failures.

Understanding the Problem: What Causes an HVAC System to Freeze Up During Hot Weather?
A frozen air conditioning system occurs when there is a buildup of ice on the evaporator coil, which is responsible for cooling the air. This ice formation restricts airflow and reduces the unit’s ability to cool effectively. If you experience a frozen air conditioning (AC) unit, it could be due to several reasons. Some of the most common causes include blocked airflow, low refrigerant levels, or mechanical problems. If your system suffers from insufficient airflow, condensation can form on the coils and freeze them; and low refrigerant levels can lead to low pressure that causes the coils to freeze. Mechanical failure of the blower fan, compressor, or other components can also lead to lower pressure and an air conditioner freeze.
Troubleshooting the Problem: How Can You Fix a Frozen AC Unit?
A frozen AC unit will not fix itself. First, you need your AC unit to thaw. To defrost your AC, you must turn off the thermostat and turn on the fan, so the ice on the coils melts and the coils can dry. Then you need to find the reason for the problem. Whether the cause is that the airflow is blocked due to dirty air filters, there is a refrigerant leak, or something else, finding the root cause is key to solving the problem. Finally, you need to address the issues you find that could be contributing to the problem.
Solving the Problem: Call the Professionals
While you can troubleshoot and even do some maintenance tasks yourself like cleaning or replacing the air filters, the best way to fix the problem of a frozen AC unit is to contact a professional HVAC technician to diagnose and resolve the issue. They have the expertise required to identify the underlying cause and can address it. Making sure you schedule routine maintenance will support your AC’s optimal performance and help prevent future freezing.
