1- Blocked Condensate Lines Can Cause AC Coils To Freeze
Blocked condensate lines are one of the most common reasons behind AC coil freezing. The purpose of condensate lines is draining away the excessive moisture from humidity and it is a part of the HVAC system. Then through pipes, this moisture goes to a floor drain. If the pipes are clogged then the water in the pipes gets stuck and this can result in freezing.
There are more chances of freezing if the pipe that is near to the evaporator coil gets clogged because it is the coldest place of the air conditioner. To fix this, the first thing that you have to do is shut off the ac and leave it for some time to defrost and then you should clean your AC properly. You can also contact the servicing companies.
2- Damaged Fans
The fans help in pushing the air through the system. The fan circulates the air around the coils and makes sure that it doesn’t get too cold. So if the fan gets damaged then no air will be pushed through and lack of air can cause freezing of the coils. You should call the servicing to change the damaged fans.
3- Dirty Air Filters
This is also a common reason behind AC freezing. Not only damaged fans but dirty filters can also freeze your ac coils. If you don’t do proper cleaning and servicing of your AC, then you will face this issue. If you want your AC to work properly, then you should make sure that the air filters are clean otherwise it will hinder the airflow. The coils will get too cold, if the air doesn’t circulate properly around the coils, resulting in freezing.
If you want to save some money, then you can do it yourself. First, defrost the AC by shutting it off. Then you will have to buy new air filters. You can get them easily and they are also cheap. After that, you will need some tools to open the AC and you can change it by yourself. You should only do this if you have experience.
4- Temperature Issues
Air conditioners are designed to operate at a specific temperature. Your AC will freeze if the outside temperature goes below 65 degrees. It usually happens in the cold nights of summer when the outside temperature drops. To avoid this, you should have a thermostat that can shut down the AC when the temperature drops than the normal limit. If you already have a thermostat in your AC, then malfunction of the thermostat could be the reason. You should contact the service to fix it.
5- Refrigerant Leaks
Enough refrigerant is very important for the proper functioning of your AC. It is a kind of chemical that helps in absorbing the heat by changing the pressure and temperature. If the refrigerants get low, then it can cause a lack of heat, result in absorbing more heat. Excessive heat loss can cause coils to freeze. If you notice a leak in refrigerant, then you should contact professional aircon help because it is harmful to the environment and it is also illegal in some countries.
Conclusion
These were some of the reasons What Causes Aircon Coil to Freeze. If you don’t want to face this kind of problem, then make sure that you maintain your ac properly. It is a machine and like all other machines, it needs time to time servicing. So if you don’t want to spend extra money on the new replacement, then start giving attention to your air conditioner.
