How To Fix Your Freezing AC

Summers in Michigan can be fun, but it also means you need to make sure your air conditioner is working right. Many homeowners have to deal with the annoying problem of their air conditioner freezing up when they need it the most.

At AAA Service Network, we know how uncomfortable and annoying this can be. We'll talk about why your air conditioner might freeze up in the summer and give you some ideas for how to fix it so you can stay cool and comfy all summer long.

Why Your AC Freezes Up

Having your air conditioner freeze up in the summer is harmful, especially when it's very hot. When your air conditioner freezes, it means that the evaporator coils, responsible for cooling the air, have accumulated an excessive amount of ice. Several factors can contribute to this issue, including:

• Poor airflow: Restricted airflow over the evaporator coils can cause condensation to freeze instead of draining away. Common culprits include dirty air filters, blocked vents, or issues with the blower motor.
• Refrigerant levels: Low refrigerant levels may lead to a drop in pressure within the evaporator coils. Reduced pressure causes the coils to get colder than they should, resulting in ice formation.
• Thermostat settings: Setting the thermostat too low can cause the system to run longer than necessary, leading to overcooling and freezing of the coils.
• Outdoor temperature: In cooler weather, especially during chilly summer nights, the AC may not be designed to handle such low temperatures, causing the coils to freeze.
• Mechanical issues: Problems with components like the expansion valve or the defrost timer can disrupt the normal cooling process, leading to ice buildup.

How To Fix a Frozen Cooling System

While a frozen AC can be a headache, some simple troubleshooting steps can help get your cooling system back on track or help you determine how serious the problem is.

Follow these simple steps to troubleshoot your system:

1. Turn off the AC: At the first sign of freezing, turn off your air conditioner to allow the ice to melt and prevent further damage.
2. Check air filters and vents: Regularly clean or replace air filters to ensure proper airflow. Also, ensure that all vents and registers are unobstructed and open.
3. Inspect refrigerant levels: If you suspect a refrigerant leak, it's essential to call a professional HVAC technician to assess and fix the issue.
4. Adjust thermostat settings: Set your thermostat to a reasonable temperature to avoid overworking the system.
5. Defrosting the coils: Once the ice has melted, you can restart the AC. However, if the problem persists, it's best to seek professional help.

Having an AC system that freezes up can be a challenging situation. Trying to fix the problem without proper knowledge and expertise could potentially cause more harm and safety hazards. It's best to rely on a professional HVAC technician who has the necessary skills to accurately diagnose the root cause of the freezing and carry out the appropriate repairs.
