Enjoying the benefits of an AC during hot days can be short-lived if your unit starts to freeze up. This can be a very frustrating problem; thankfully, once you call air conditioning repair services, they'll get to the root of the problem and restore comfort at your residence.

Ensure to resist any urges to attempt DIY repairs as you wait for the professional to arrive; you might worsen the underlying problem. Nonetheless, it's always good to know what sometimes causes your equipment to malfunction. So read along to learn why your air conditioner is frozen.

1. Low Refrigerant Levels

One reason your AC might be freezing is that it could be low on refrigerant. This common issue can happen due to normal wear and tear of the components that the fluid flows through. If the evaporator coil, compressor, or condenser coil cracks open, some refrigerant can start to leak when the unit is cycling.

Eventually, the refrigerant levels will drop and cause the evaporator coil to freeze. This phenomenon happens because there isn't enough fluid to draw latent heat from your indoor spaces.

2. Faulty Components

The nature of the operation of an AC is such that all the parts work together to ensure its efficient functioning. When any of these components fail or get damaged, it can cause the system to malfunction and sometimes even freeze.

The parts whose malfunction can result in equipment freezing include the compressor, evaporator coils, and air handler. Thankfully, a professional technician can identify which component is not working as it should and fix it as needed. This will restore normal unit operation and prevent any costly repairs or replacements down the road.

3. Thermostat Issues

In some cases, an AC can freeze due to a problem with the thermostat. If the thermostat is not working properly, it can cause the AC to cycle on and off erratically. This, in turn, can lead to the unit freezing up.

To resolve the issue, you should let air conditioning repair services find out what's wrong with the thermostat. They will let you know if a simple recalibration will suffice or if you should invest in a new thermostat.

In most cases, the problem is an incorrect thermostat setting that's confusing the equipment. Your technician will show you how to pre-set the thermostat so it can support your equipment accordingly.

These are some of the most common reasons why your air conditioner might be freezing up. If you are having this problem, it's best to call air conditioning repair services to come and take a look. They will be able to quickly diagnose the problem and get your AC unit up and running again in no time. For more information, contact a company like Carolina Air Care.
