Do you ever wonder why your air conditioner gets frozen? AC units are designed to create a cool indoor environment despite the hot, humid outside weather. But if your unit freezes up, its efficiency is greatly compromised, which not only causes discomfort but also increases your electricity bills. Eventually, neglecting to fix this problem can lead to permanent damage to the system.
When you notice that your air conditioner freezes after running for some time, it will have a hard time circulating cooled air, and after a bit, a huge block of ice may accumulate on the evaporator coil. Some of the common indicators of a freezing AC unit include a soaked filter, a thick layer of ice coating the pipes, a lot of condensation on the drain pan, and an uncomfortably warm room.
Cooks Air Conditioning and Heating is your trusted HVAC company in Palm Coast FL that can help you fix a freezing AC unit.
Below are some of the most common causes of a frozen cooling system.
Low Refrigerant Levels
The refrigerant is a critical part of your AC unit. Take it away, the air conditioner cannot transfer the heat from the inside to outside of your house. Even a small loss of refrigerant in an AC can cause many problems. That is why the refrigerant should remain at a specific level in order to keep the system in normal operation.
There are two possible reasons when an AC freezes up due to refrigerant issues: the refrigerant charge is not enough or there is a leak somewhere. Either way, a professional AC technician can detect the issues for you. Contrary to what many believe, refrigerant doesn’t get used up, so, when your unit is low on refrigerant charge, it means that there is a leak somewhere in the system, needing to be sealed off.
Low refrigerant can restrict the indoor coil from absorbing the proper amount of heat. Not only does this compromise the cooling capacity of your air conditioner, but it also causes the evaporator coil to begin to freeze since the refrigerant’s temperature is not rising high enough. The more ice buildup throughout the expanse of the coil, the less it can absorb heat, resulting in diminished cooling that will eventually cause the unit to completely lose its cooling power.
Failure to address low refrigerant levels can damage the compressor, which is otherwise known as the heart of the air conditioner. The compressor is engineered to match the refrigerant charge, and if it trickles, the compressor will start to work with added pressure and will soon break. A faulty compressor is a huge expense you should avoid, so have a professional fix the issue as soon as you discover the problem.
A Broken Blower Fan
The blower motor is one of the main components that can cause your AC to freeze up. Its job is to produce air movement to the space that is being cooled. As the air cools down within your air conditioner, it becomes stuffed and doesn’t travel as it should. The blower fan siphons the hot air out of your home and moves the cold air inside. The cooling power of your air conditioner depends mainly on the unit having the right balance of airflow and pressure.
As with any other HVAC equipment, your air conditioner needs sufficient airflow in order to run properly. If it doesn’t get enough air, the exchange of thermal energy between the AC unit and the room is weakened. As a result, most of the cool air stays around the evaporator coil and fins, creating a drop in temperature within the AC itself. Eventually, ice is formed, causing the unit to freeze up.
Why You Need Regular AC Maintenance
In order to keep your air conditioner performing well and avoid freezing the coils, it is important to have it professionally maintained on a regular basis. Only a qualified technician can properly check the refrigerant levels and ensure there are no leaks within the lines. Do not wait before your AC freezes up before seeing an HVAC professional.
