Why Does My AC Freeze Up Even in Hot Weather?
Frozen AC coils can be caused by restricted airflow, low refrigerant levels, or thermostat issues. If your AC is freezing up, it won’t cool effectively and may need professional attention.
Common Reasons for Frozen AC Coils
Even in hot weather, your AC can freeze up due to various mechanical and airflow issues.

Why Your AC Might Be Freezing
- Dirty air filter: Blocks airflow, causing condensation to freeze.
- Low refrigerant levels: Can lead to excessive cooling and ice buildup.
- Thermostat problems: If the temperature setting is too low, the unit can freeze.
- Blocked vents: Insufficient airflow can contribute to freezing.
How to Fix a Frozen AC
Turn off the AC to let it thaw, check and replace the air filter, and ensure vents are open. If freezing continues, contact a technician.
