Reasons Why Your Air Conditioner Freezes Up

As the temperatures outside begin to heat up, you expect your air conditioner to keep your home relaxed and comfortable. But what happens when your AC unit starts freezing up?

While it may seem counter-intuitive, air conditioners can actually freeze up in hot weather. When this happens, it is usually due to a problem with the unit itself and not the temperature outside. There are a few different reasons your air conditioner may freeze up, and knowing these can help prevent it from happening again.

Here are some of the most common reasons why your air conditioner may freeze up.

1. The Air Filter Is Dirty

One of the most common reasons air conditioners freeze up is that the air filter is unclean. A filthy air filter prevents the unit’s airflow, causing it to work harder to cool your home. This extra work can cause the unit to overheat and eventually freeze up. You should check your air filter monthly and replace it as needed to prevent this problem.

2. The Evaporator Coils Are Dirty

Another common reason for an air conditioner to freeze up is dirty evaporator coils. These coils are responsible for absorbing heat from the air, so they cannot do their job correctly when they are dirty. To prevent this, you should have your evaporator coils cleaned at least once a year by a professional AC service in Fort Lauderdale.

3. There Is a Refrigerant Leak

If your air conditioner is leaking refrigerant, it could indicate that the unit is not sealed correctly. This could be due to a problem with the compressor, or it could be a sign that your air conditioner needs to be recharged. If you suspect a refrigerant leak, it is crucial to have it fixed as soon as possible by the a/c Services Company as it can cause severe damage to your unit.

4. The Thermostat Is Set Too Low

You may be surprised to learn that setting your thermostat too low can cause your air conditioner to freeze. When the thermostat is set too low, the unit will run for long periods without cycling off, which can cause it to overheat and freeze. Air conditioning in South Florida should be set at a higher temperature to prevent this from happening.

5. The Outdoor Unit Is Blocked

If the outdoor unit of your air conditioner is blocked by debris, it cannot adequately dissipate heat. You will notice this problem because the air conditioner will stop cooling effectively. You will want to consult ac service in Fort Lauderdale experts to clear any debris and improve the cooling efficiency of your unit. This will help you stay comfortable and avoid the high energy bills that come with an inefficient air conditioner.
