Air Conditioner Air Handler Freezing Up. This key air conditioning component is full of extremely cold refrigerant. In order to keep the air flow in your own house moving enough to not disrupt your air conditioner's functionality, you need to be sure your air filters aren't dirty and becoming clogged.
9 Common Causes Why Does My Ac Freezing Up from www.pickhvac.com If your air conditioner is running low on refrigerant due to a possible leak, it can freeze up. This happens because the refrigerant in the evaporator coils can no longer absorb the heat needed for the coils to warm up. If that air flow gets interrupted or restricted, even by a dirty air filter, ice can start to build up on the coils. You must let all the ice melt before turning the a/c back on, otherwise the problem will quickly return. Common culprits include inadequate maintenance, a faulty thermostat and clogged air filters.
As you might suspect, a frozen air conditioner isn't exactly the best way to keep your house cool in summer.
As i said above the main cause of an air conditioner freezing is poor airflow, another cause of this is a bad flow divider. However, when it doesn't escape, the humidity builds up and causes water to freeze on the coils. Lack of airflow can cause an air conditioner to freeze up. You will notice that there is less airflow coming from the air ventilation as ice began to clog the air movement. This is why it is important to not run your ac during cold weather. However, no air conditioner is ever supposed to get that cold.
