Why Is My AC Freezing Up?

During the summer, you depend on your air conditioning (AC) to keep you cool and comfortable. But when your AC starts to freeze up, it’s both an inconvenience and a potential hazard. Nobody wants to come home to a broken system that’s trying to cool a room but has instead turned into an icicle.

How Does an AC Freeze Up?

An air conditioning system relies on several components to keep the air circulating and comfortable. The air handler pulls air into the system, filters it, cools it, and then blows it back out into the space it’s cooling. The system runs in a closed coil circuit, meaning the same refrigerant that cools the air absorbs the heat from it and purges it outside of the home.

When an AC freezes up, it’s typically due to an issue with one of these components. The most common issue is that the system is low on refrigerant. Cold air won’t circulate without this, so the air handler will start to freeze up. Other causes can include a clogged air filter, an issue with the fan, or a defective thermostat.

What Should You Do When an AC Freezes Up?

If your AC freezes up, it’s important to take immediate action. Shut off the unit and give it a few hours to thaw out. If you notice any water damage on the floor near the unit, contact a professional for help. Otherwise, check the air filters and clean them if necessary. Check the thermostat to make sure it’s set to “cool” and the temperature is at least five degrees lower than the current temperature of the room. Finally, make sure the fan is operating correctly and that the coolant lines are free from any blockages.

If none of these steps resolve the issue, it’s time to call in a professional. A reputable appliance repair technician has the know-how and tools to diagnose the issue and quickly resolve it. Issues with the AC can cause costly damage to the home and can also put your family’s safety at risk, so it’s best to get professional help as soon as you notice a freeze up.

Prevention of AC Freezing Up Issues

The responsibility of preventing AC freezing up issues depends on many parties: manufacturers, local appliance companies, and HVAC technicians. Each of these parties should be aware of the best practices in order to ensure that ACs continue to run efficiently and take necessary preventive action when needed.

Manufacturer Recommendations

Manufacturers are the first in line for AC freezing up issues, as they have the expertise in designing and constructing the ACs themselves. Therefore, it is essential to take notice of the manufacturer’s recommended service and maintenance guidelines. Regular inspections should be done to ensure that all parts are running properly, and all exposed areas are kept clean and without debris. If necessary, more elaborate maintenance, such as component replacements and filter cleanings, should be done according to the manufacturer’s instructions.

Local Appliance Companies

Once the manufacturer’s guidelines have been followed, local appliance companies have a further role to play in the prevention of AC freezing up issues. Depending on the availability of suitable appliances and spare parts in their local area, they should then be able to make accurate assessments of any necessary repairs. Their expertise should enable them to diagnose any potential AC freezing up related issues, as well as recommend suitable upgrade or replacement plans.

HVAC Technician Recommendations

Finally, HVAC technicians are invaluable when it comes to the prevention of AC freezing up issues. They often possess a wealth of knowledge regarding the components and systems that make up an AC, and can accurately identify and resolve any underlying problems. As well as being able to make informative assessments on any repairs, HVAC technicians are also able to provide an overall checkup of the system to ensure that everything is running correctly and at optimal efficiency.


The prevention of AC freezing up issues requires the collaboration of manufacturers, local appliance companies, and HVAC technicians. By following the manufacturer’s recommended service and maintenance guidelines, local appliance companies can assess any necessary repair plans, and HVAC technicians can diagnose and fix any potential issues. In doing so, these parties can work together to reduce the likelihood of AC freezing up and safeguard a more comfortable indoor environment.
