How to Fix a Frozen Air Conditioner
Frozen air conditioners are very common in the summer. This is probably one of the most common issues most homeowner have to deal with, sometimes even on a regular basis. Although the basic AC maintenance guidelines suggest we shut down the unit and call for air conditioning repair, fixing a frozen AC is not such a hard task. With some tools, elbow grease and our suggestions, you may be able to do it yourself.
But before I explain you how to unfreeze your AC, let’s first see why they freeze up in the first place. There are two main reasons for this: refrigerant leaks, and lack of airflow.
Lack of airflow is one of the most common reasons for frozen AC units. The problem starts from the filters. If they are not changed regularly, eventually they will become full of dirt and debris. This will diminish the airflow between the outside unit and the indoor one. When the evaporator coil (indoor unit) stops receiving proper air flow, it starts accumulating ice between the fans. The less air it receives, the more ice it accumulates, and eventually the entire unit becomes covered in ice. As you can imagine, the repair involves replacing the dirty filters.
The other problem that may cause an AC to freeze up is lack of refrigerant. This can happen only when there is a leak somewhere in the system. Leaks usually occur at fittings or at the evaporator coil. If you notice refrigerant under your inside unit, it means the coil is cracked or damaged. In order to fix it, you have to call a professional AC repair service as the job requires special tools and equipment.
Once you’ve determined what exactly caused your unit to freeze, and you’ve fixed the problem accordingly, you can finally move on, and defrost your air conditioner. All you need to do is unplug the AC unit and place a big bucket under it. The best way to handle this is to wait for the ice to melt naturally. Any additional source of heat may damage the internal components or bend the front cover. You should also call for an air conditioning repair service and let professionals inspect your unit for any damage that may have appeared during the freezing.
