Putting Your Home on Ice: Why Is My Air Conditioner Frozen?

As the temperatures start warming up, there’s nothing you want more than to turn on your room’s air conditioners and enjoy the cool air running through your home. However, you notice that you’re not quite getting the cooling sensation you were expecting, so you take a look and find something you never thought you would see: ice. What this means is that you have a frozen evaporator coil or frozen condenser coil, and you will need to have it dethawed by a professional.

Before calling a central air repair service out to your home to make the repairs, let’s examine how you got into this predicament in the first place. There are a few reasons why your coils are freezing, so let’s take a look at the most common causes and find out how to avoid these mishaps moving forward.

Dirty Coils

As part of your routine maintenance, you should be making sure that your coils are cleaned. If they are caked with dirt and dust, they may have difficulty absorbing heat. This issue can snowball into problems with your airflow, restricting your unit’s ability to process the heat and causing your coils to get much colder until they eventually freeze over.

While we don’t expect you to be looking for frozen coils all by yourself, you can have a professional HVAC technician evaluate your central air conditioners and ductless mini-splits to see if they are due for a cleaning. Keeping up with this easy bit of maintenance is one of the most efficient means of keeping your AC unit from freezing over when you need it most.

Poor Airflow

The most important part of your air conditioner is making sure that your air flows throughout your home without any hiccups — however, this is one of the most common HVAC problems you can come across. Poor airflow can be caused by a variety of factors, from the aforementioned dirty coils to dirty air filters and problems within your ductwork. You may also have a malfunctioning air handler, which is critical for moving cool and warm air throughout your home.

Cleaning your air filter should already be something you do a few times per year, as it is not only energy-efficient and good for your indoor air quality, but it helps you prevent issues such as frozen coils. If addressing airflow issues is not already on your HVAC maintenance checklist, we highly advise you to add it as soon as possible.

Low Refrigerant Levels

You would think that not having enough refrigerant would have the opposite effect, but you would be wrong! Not having enough refrigerant in your air conditioning unit prevents your system from working properly, causing it to overwork itself, allowing molecules to expand and freeze.

Pay attention to your unit and be on the lookout for any refrigerant leaks or low levels. Your HVAC professional should be able to fix any leaks or refill any low refrigerant charge, allowing you to keep your home cool again. If these issues go ignored, you are likely heading for frozen coils that will ruin the comfort of your home that you have been looking forward to enjoying.
