Every summer leads up to that one sweet moment where you can turn the air conditioner on with no guilt. But what if, when you go to turn it on, you find it frozen?
An air conditioner is the kind of appliance that requires regular care and maintenance. This is because; there are so many things that could go wrong with the machine. It could not turn on, it could be leaking water or in this situation, it’s iced up.
Hence, to help you out, we have here a brief guide on what causes the air conditioner to freeze up and what to do when it does.
Causes for the AC to freeze up
A constant flow of air is essential for the normal functioning of an air conditioner. The air flow ensures that humidity does not cover the coils. This is because, if humidity settles on the coil, they freeze up. Air filters regulate the air flow. Thus, regular maintenance and replacing is a priority.
A slight change in the functioning of one of the parts of the air conditioner means that the refrigerant could leak. Damage or clogging can cause a change in the pressure inside the appliance. Drop-in pressure means that the refrigerant will expand and become too cold. As the refrigerant regulates the temperature of the air conditioner, it can also cause the AC unit to freeze up.
The coils, due to their structure, often have ice get stuck on them. If this is not cleaned out often, then the ice deposits could turn into massive blockages. The AC freezes up because the layer of debris on the coil prevents them from absorbing the water/ AC coils also freeze up when the drip pan is full and the condensation droplets have no way of being drained.
The function of a blower fan is to guide the cold air to its right place and the warm air to the outside. The airflow and pressure in the air conditioner is highly dependent on the functioning of this fan. If the blower fan is damaged or broken, there are significant changes that take place. Condensation will build up on the coils, causing the AC coils to freeze up.
Air conditioners are built to function in certain optimum temperatures only. When the temperature outside moves below this threshold, the air conditioner freezes up. If the temperature outside drops, the pressure in the AC unit will also drop causing the unit to freeze up.
Certain issues with the part of the appliance, such as clogging or damage, could easily result in the air conditioner freezing up. These should be regularly checked and repaired accordingly.
How To Fix AC Freezing Up Problem?
- Take a good look at the air filters as they often need replacing. Replacing the air filters within the required time will save you a lot of trouble. Be more thorough with this in the summer as they tend to get damaged more often.
- Cleaning the evaporator coil will save the AC from freezing up. Use a small brush to clean away all the dirt, dust and debris that has collected over time.
- The refrigerant is a coolant and must be topped up every once in a while. As the refrigerant controls the temperature of the air conditioner, ensure to do this in regular and sufficient intervals.
- When having an air conditioner installed, make sure to also have a thermostat installed as well. The thermostat will help you keep an eye on the temperature levels so that you can prevent the air conditioner from freezing up.
