What is Causing Your Air Conditioner to Freeze Up?

Have you recently noticed that your air conditioner is blowing warm air or no air at all? This happens because your air conditioner is freezing up due to the temperature in the condenser’s evaporator coil dropping too low. There are many reasons this could be happening, but here are the most common issues that might be causing your air conditioner to freeze up.

1. Clogged air filter

Severely clogged air filters can cause the engine on your air conditioner to stall or malfunction. This can cause pollution buildup and restrict airflow, causing your air conditioner to freeze. Maintaining your air filters is a task that’s not hard to forget, but it’s something that should not be neglected if you want to prevent your air conditioner from freezing up.

2. Refrigerant leak

Refrigerant leaks are caused by holes and cracks in the coils of your AC unit. These leaks will cause your AC to freeze and lose cooling power. Always check for refrigerant leaks if you notice your AC unit making a hissing noise (caused by holes and cracks in the coils) or not blowing cold air. Ignoring this can lead to more severe problems such as water leakage in your home.

3. Dirty evaporator coils

Dirty evaporator systems can cause a lot of strain on your AC system. Dirt in your evaporator system will impede airflow through your air conditioner and cause AC freezing. It will also result in higher energy consumption which will result in higher electricity bills.

4. Faulty AC equipment

Faulty AC equipment, such as thermostats and leaking ducts, is another common cause of air conditioning freezing. Bad AC equipment will reduce performance and increase your electricity bills by putting stress on your equipment. If you’re looking to save money and reduce your air conditioner’s lifespan over time, you should call a professional air conditioner repair company to fix this problem for you.
