In the summer heat, the last thing you want is for your air conditioner to freeze up. But it happens, and usually for one of four reasons. If you're having this problem, check these potential causes before calling for repairs.

1. The air conditioner is too cold. This seems like a no-brainer, but it's possible to set the thermostat too low without realizing it. The ideal temperature is around 78 degrees, so if you're setting it lower than that, the unit will have to work harder - and use more energy - to cool the space down. As a result, ice can form on the coils.
2. The evaporator coils are dirty. These coils are located inside the unit, and over time they can accumulate dust and dirt. When that happens, they don't absorb heat as efficiently, which means the unit has to run longer and use more energy to cool the space. To clean the coils, turn off the power to the unit, remove the coil access panel, and use a soft brush or vacuum attachment to clean them lightly.
3. The air filter is dirty. This is another common cause of ice formation. The air filter's job is to keep dirt and dust out of the unit, but it can restrict airflow if it gets too full. That can cause the coils to freeze up. Consult your owner's manual to clean or replace the filter; some filters can be washed, while others need to be replaced.
4. There's a refrigerant leak. If your unit is low on refrigerant, it won't be able to cool the air effectively. Ice can form on the coils as a result. This is a job for a professional; don't try to add refrigerant yourself, as that can damage the unit.

How Can a Freezing AC Be Repaired? If your air conditioner is freezing up, it's essential to address the problem immediately. Otherwise, the unit could sustain severe damage. Once you've determined the cause of the problem, could you take steps to fix it? Call a professional if you're not sure what's causing the issue or can't fix it yourself. Can My AC Break if It Freezes? An air conditioner can break if it freezes, but it's not likely. The most common problem is that the unit will stop working altogether. If this happens, you'll need to have it repaired or replaced. In some cases, the unit may start working again once the ice melts; if that happens, it's best to call a professional to check it out and make sure there's no permanent damage.
