Each summer, homeowners face the difficult task of ensuring that their home is cool and comfortable. However, it can be a major inconvenience when your AC unit freezes up. Here are four things to do when your AC unit freezes up so you can get back to keeping cool.

1. Check and Clean the Evaporator Coils

When the evaporator coil becomes too cold, it can cause the temperature of the air around it to drop below freezing, resulting in ice buildup on the unit. To prevent this, contact professional at Mackey Services to check and clean the evaporator coils regularly. If you notice the coil becoming dirty, wipe it down with a cloth soaked in warm water, a brush or a vacuum cleaner.

2. Turn the Thermostat From Auto to On

When your AC unit freezes, turn your thermostat fan setting from “auto” to “on.” This will cause the fan to run continuously, helping to thaw the ice and prevent further freezing of the unit. Once the ice has melted, you can return your thermostat to the “auto” setting.

3. Unclog the Condense Line and Drain

When there is a blockage between the condense line that connects your AC system and the outdoor drain pipe, debris will accumulate inside the unit’s reservoir, where the moisture trapped within will condense, freezing on the coils. Therefore, you should unclog the condensate line and drain it to help remove any water to prevent further freezing. You can use a plunger or a small brush to clear the line.

4. Clean or Replace the Return Air Filters

You should consider cleaning the return air filters when your AC unit freezes. This is because, over time, these filters can become clogged with dust and debris, which can restrict airflow and cause your AC unit to freeze up. However, if the return filters are older or have been poorly maintained, it may be necessary to replace them.
