How to Properly Handle a Frozen Air Conditioner

Throughout the lifetime of your air conditioning unit, it can encounter several problems – one of which is getting frozen. There are many reasons that could cause this problem, but the most common reasons for a frozen AC system includes:

  • Dirty evaporator coils
  • Malfunctioning motor
  • Blocked or insufficient return ducts
  • It’s not receiving enough airflow
  • Low refrigerant

Not only is it impossible to use a frozen AC system, but it can also slowly damage your property. As such, you need to deal with the problems ASAP.

Here are a number of tips on how you can handle a frozen air conditioning unit:

1. Clean the Evaporator Coils

The evaporator coils are made to absorb heat from the refrigerant, so a dirty coil typically can’t do its job efficiently. Reduced heat transfer also means the AC has a higher risk of freezing over, so you have to have the coils cleaned regularly.

Although it’s possible to do this on your own, it’s better to let air conditioning experts handle it. The pros have the skill and the necessary equipment to properly finish this complicated task.

2. Repair or Replace the Malfunctioning Motor

If the reason behind your frozen AC is a malfunctioning motor, the best way to deal with the situation is to have it professionally repaired. In some cases, replacing the air conditioning system it is a better option – especially when the motor is really old or worn.

3. Unblock the Return Ducts

The vents and return ducts in your home are there for a reason, and it’s to help your home receive sufficient cool indoor air. If they’re blocked, it will increase the pressure inside your HVAC system and cause various parts of your AC to freeze up.

With that said, you should make it a habit to inspect your property and remove anything that’s blocking the return ducts and vents.

4. Change or Clean the Air Filter

The air filter in your HVAC system prevents airborne pollutants from contaminating your indoor air quality. As such, it gets filthy over time. Leaving the filter dirty restricts the necessary airflow the evaporator coil needs to absorb heat. Thus, it’s ideal to change or clean the air filter every thirty days.

If you’re trying to change the air filter in your frozen AC, wait until the ice melts before proceeding.

5. Insufficient Refrigerant

If your air conditioner refrigerant is low or leaking, the pressure in the evaporator coil drops. When this happens, moisture has an easier time accumulating on the coils and freezes as the temperature decreases.

In this situation, it’s highly recommended that you hire the AC experts to take care of it. They know what proper steps to take to stop the leakage and have enough supply to refill the refrigerant. This also indicates that you should replace your air conditioning unit soon. Freon, which is the most commonly used refrigerant, will be illegal to use by 2020.

Preventing your AC from freezing isn’t the most simple thing in the world but it’s also not that difficult. Plus, most of these problems can be conveniently solved if you let the professionals take care of it, so you don’t have to waste any extra time or energy.
