Having a cozy and temperature-controlled house is important, especially during the summer. But what happens if you come across your frozen air conditioner? Actually, it’s more than just an inconvenience; it’s a serious issue that needs immediate attention. Many people are unaware of how to prevent the frequent problem of freezing air conditioners. This situation can quickly transform a lovely summer day into an extremely hot one.
To help you out, we have created this blog to explain the causes of frozen air conditioners and provide some helpful advice on maintaining a cool and cozy house. This information will benefit you in maintaining a cool indoor environment throughout the summer, whether your air conditioning unit is currently frozen or you are seeking ways to prevent it from happening in the future.
You will get to know more about your air conditioner’s workings as well as how to maintain it by the end of this blog. So, continue reading for more information, regardless of how knowledgeable you are about air conditioning or how new you are to it.
How Do Air Conditioners Work?
The refrigerant’s liquid state then passes through a capillary tube or expanding valve as it reaches the indoor unit through a little line. By decreasing the refrigerant’s pressure, this valve’s function causes it to expand quickly while remaining extremely cool. The refrigeration fluid expands and absorbs heat from the air that’s going over the evaporator coil, which is located inside. This cools the air and absorbs moisture, dehumidifying it during the process.
After cooling down, the heated refrigeration gas travels back to the outside unit in order to begin the process all over again, and air that has been cooled is pumped back into the indoor environment through the supply vents. Following that, the compressor’s operation restarts the cool-down process again by compressing the gas.
Air conditioners can maintain cool inside temperatures by constantly compressing, condensing, expanding, and evaporating refrigerants. This makes it possible to build a pleasant environment regardless of humid and hot environments. Air conditioners wouldn’t work as efficiently as they do in the absence of this process. Millions of people globally depend on the reliable and efficient cooling provided by current air conditioning systems, which are mainly designed around the process of refrigeration.
The Reasons Behind Freezing Air Conditioners
- Restricted Airflow – Restricted airflow is one of the main causes of air conditioner freezing. The moisture on the coil of the air conditioner can turn into ice whenever it fails to bring in sufficient warm air from the inside of the home. Airflow issues can frequently be caused by a dirty or blocked air filter. Check your ventilation systems and ducts for anything restricting the airflow if replacing the filter does not work. These paths must remain clear to avoid your air conditioner freezing up.
- Insufficient Refrigerant Levels – Your air conditioner could freeze up due to an insufficient amount of refrigerant. This is usually an indication of a refrigerant system leak. Low refrigerant can be the reason for any whistling noise you hear from your air conditioner or any unexpected warm air blasts. To fix the leak and restore the refrigeration fluid to the proper amount, it’s important to get in touch with a professional. Trying to manage a refrigerant leak on your own could be a risk due to the possibly dangerous chemicals involved.
- Damaged Or Faulty Blower Fan – A significant reason why air conditioners freeze up is a damaged or faulty blower fan. By blowing warmer air over the coils, the blower fan benefits significantly in the process of cooling and helps you control the indoor temperature of your house. The coils of the evaporator can freeze as a result of a damaged fan or insufficient airflow, which could affect the workings of your air conditioner. It’s essential to take immediate action to fix blower fan problems if you would like to keep your air conditioning system functioning properly while preventing other problems.
- Unclean Evaporator Coils – Air conditioners often freeze because of unclean evaporator coils. These coils’ capability for transferring heat can be decreased over time by the build-up of dust and grime. With the barrier-like effect of this accumulation, the coils don’t get as cold as they should be. It could possibly lead to problems with water freezing by blocking condensate lines. That means your air conditioner will be forced to work harder, consume greater amounts of energy, and freeze more often than usual. To avoid such problems and maintain the smooth functioning of your air conditioner, it is important to regularly clean the coils.
- Broken Thermostat Unit – A possible root cause of your air conditioner freezing up could be a broken thermostat unit. The thermostat could be incapable of turning off in the manner it should, which can contribute to the coils freezing if you find that your unit freezes more often at night. Your thermostat’s batteries can be changed easily as a temporary solution. If this is unable to resolve your problem, it’s probably time for a new thermostat purchase. You must inspect the functionality of your thermostat if you want to avoid your air conditioner freezing over time.
What Should Be Done When Handling A Frozen Air Conditioner?
It’s important to take action right away when your air conditioner freezes to avoid further problems and restore functionality. You can fix the problem and maintain the pleasant environment of your house by knowing what to do when your air conditioner freezes.
1. Switch Off The Air Conditioner
When the atmosphere around it gets warmer, the ice will begin to melt on its own, but this process of melting could take many hours. If the inside of the home becomes very warm, use fans to increase circulation or open up windows and doors to let in fresh air. If you need to break the ice, do not use sharp objects, as this can lead to more problems. Simply, just wait for the ice to break down on its own.
2. Remove Moisture From The AC Coils
Using an external fan for blowing air around the coils or switching on the blowers inside the machine is going to speed up the drying process. This might take an hour or a little longer, depending on the amount of moisture. You can safely get back to your usual routine once you have made sure the AC’s interior is completely dry.
Ways To Avoid An Air Conditioner Freezing Up
Consider taking some of these preventive measures into action to keep your air conditioner operating efficiently and save yourself from the stress of it freezing up.
1. Change Or Clean The Air Filter Frequently
But, filters may become clogged with dirt accumulation gradually, which makes it more difficult for air to pass through. One of the most important things that you can do to prevent your AC from freezing is to keep your air filter clean. To guarantee that the air conditioning in your home operates efficiently, replace or clean the filter as directed by the manufacturer frequently.
2. Pay Attention To The Refrigerant Level
Since HVAC specialists have the knowledge to handle technical difficulties such as refrigerant levels and leaks, it is better to leave this duty to their hands during your yearly maintenance check. You can keep the air conditioning in your home operating smoothly and effectively by making an early maintenance appointment. This ensures that any problems with the refrigerant are detected and fixed, including leak repairs and system recharges.
3. Check Proper Installation
By doing this, you can feel confident that the system has been set up properly, which will decrease the possibility of problems and guarantee its efficient operation. A proactive approach to maintaining an effective air conditioning system and minimizing future freezing-related issues is to hire an experienced professional for installation. This will prevent your problems and allow you to relax during the summer in a cool and cozy interior environment.
In Conclusion
To keep your air conditioner functioning at its best while avoiding expensive repairs, you must understand the reasons for air conditioner freezing. A combination of any of the following problems may cause an air conditioner to freeze: a broken thermostat, dirty coils, low refrigerant levels, restricted airflow, mechanical issues, and so on. Homeowners can make sure that their air conditioning systems run smoothly and effectively throughout the entire year by taking proactive measures to solve such issues through immediate repairs, routine maintenance, and the correct installation.
