Air Conditioning freezing up? How can something that works all the time throughout the hottest days of the year be prone to freezing? Despite the paradoxical take the place of an AC freeze in the summer season, air conditioning unit freezing up is something that occurs a lot. Very few property owners are geared up with the knowledge and comprehending about air conditioners to prevent this issue on their own. It’s an issue that can turn a beautiful summer season day into a blistering hot one in minutes.
How can you tell if you might be dealing with a freezing issue?
A sure sign is to check the supply registers. Is it warm? If so, that’s an excellent indicator of frozen evaporator coils. Open the panel and look for ice. Remember, an absence of ice does not always suggest that you’re not having a freezing problem. Seeing ice is pretty-well a guarantee that your AC is frozen.
Understanding the Joule-Thomson impact
Before we look into the reasons for an Air Conditioning freezing up, let’s talk a bit about how your Air Conditioning works. We should comprehend that temperature is how much energy a particle has. When the air feels hot, it’s since the particles in the air have a great deal of energy and are moving around quickly. The same works in reverse, cold air is comprised of low energy molecules. What the Joule-Thomson Effect demonstrates in thermodynamics is when the air in our ACs isn’t compressed, its temperature will reduce as it expands and the molecules slow. When it is compressed, the molecules get delighted and warm up.
The point of an air conditioning system is to broaden the refrigerant inside the evaporator coil so that it cools off, so when it leaves the ac system, it cools the air inside your house and effectively gets rid of the hot air from inside your house. Nevertheless, if something in the air conditioner breakdowns, the whole system gets disrupted. This causes the evaporator coil to permit the refrigerant to cool too much, causing it to fall below freezing and ice over.
How can you prevent something in the cooling formula from going extremely incorrect? There are three primary causes that cause an Air Conditioning freeze up. By understanding these causes, you can go out in front of them, so you never have to experience an Air Conditioner freeze. Plus, we’ve included how to repair each cause, so if you do have an unfortunate A/C problem, you’ll be able to repair it in no time flat. Keeping your a/c in fantastic shape will assist it run more efficiently, saving you money on your energy costs, and keep it from ending up being an eyesore.

1. Blocked Air Flow Causes Freezing Up
Air conditioning unit requires to have a constant circulation of air so that humidity can’t pick the coils and freeze. To keep the air circulation in your own house moving enough not to disrupt your ac system’s functionality, you require to be sure your air filters aren’t dirty and becoming blocked. This restricts the air circulation in your home. Air filters are cheap, and it’s best to change them frequently. Keeping your Air Conditioning tidy and tuned up is likewise a good concept for avoiding air circulation issues and other issues in general. Plus, the United States Department of Energy reports that changing your HVAC filter can enhance the performance of your HVAC devices by 5% to 15%.
Another drawback of a blocked airflow is that coils in your ac compressor get hot while the compressor is still running, this can spoil the compressor.
How to Fix It:
Your Air Conditioning is already obstructed, and you found that your air filters were clogged. It’s likely a blocked airflow problem. The first thing you need to do is switch off the air conditioning system and let it thaw. After it’s had sufficient time to thaw (1-3 hours), turn on simply the fan for about an hour. Use this time to alter your air filter. You can take a look at our post on how and when to change your Air Conditioner filters. After that, your Air Conditioning must be back to regular working order.
2. Mechanical Problems or Refrigerant Leaks?
Ac system has plenty of moving parts that can get stuck, broken, or blocked. Refrigerant lines can kink, fans can stop moving, filters can end up being clogged, and things can leak. Any of these things trigger a drop in pressure, enabling the refrigerant (Like R32 and R410a) to expand excessively and end up being too cold. Refrigerant is likewise an important part in making sure a controlled temperature level throughout your device. A too-low level of refrigerant is also understood to trigger freezing up. A few of these problems are much easier and less expensive to repair than others. In the case of a coolant leak, any fix is likely just to be a short-term fix. It might be time to consider buying a new maker.
How to Fix It:
Mechanical issues and leak repairs go a bit beyond a brief guide to AC freezing. It’s finest to tackle these problems with the help of a trained professional who understands how to manage refrigerants. Refrigerants are safe to utilize in the home; they’re best handled by a specialist who understands how to keep it included. If you suspect mechanical failure or leaks might be the reason for a malfunctioning A/C, get in touch with an HVAC business and have an expert actually come offer the problem an appearance. You can help prevent disastrous concerns with your AC by getting regular tune-ups by an HVAC specialist.
3. Cool Summer Nights Can Cause Your AC to Freeze
Air conditioners are adjusted to run within a specific set of maximum temperature level thresholds. When nights in the summertime are cooler than the optimum threshold can account for, it can throw an AC out of whack.
Here is some more info on how to change your A/C’s air filter.
How to Fix It:
Having a programmable thermostat can instantly get ahead of the issue by shutting down the AC when temperature levels get below 60 degrees. If you do not have a programmable thermometer, watch out on the current temperature levels each night and anticipate if it’s going to be cooler than 60 degrees. In which case, you must turn off your AC and open your windows to let in the cool summer season breeze instead.
Summing It Up
A freezing A/C is a very typical, discouraging problem that house owners face. However, the issues causing a frozen Air Conditioning are preventable with some routine upkeep and tune-ups. Tune-ups and changing air filters frequently go a long way to preventing mechanical failures, clogs, and leakages. Employing an expert HVAC service and getting a yearly Air Conditioner Tune-up and making the most of Maintenance Service Plans, should assist you to keep your Air Conditioner in great shape, will conserve you cash on your energy bill and assistance keep your Air Conditioner system running for years and years.
