Summertime is fast approaching, which means that the temperature is slowly rising. You’ll want to enlist the services of your air conditioning system once more, all needed to keep your home cool and comfortable throughout the season. More often than not, however, an air conditioner can stop being reliable for a multitude of reasons. 

One of the most prevalent problems is a low refrigerant level, which prevents your unit from performing at its maximum capacity. Keep in mind that refrigeration systems operate as closed circuits, making it necessary to have refrigerants present at all times. However, too much of anything is never good, as this can lead to extra stress on the compressor or excessive condensation.

Unfortunately, too low refrigerant levels can also lead to water damage and other problems. The question now stands—how do you know when it’s time to have it checked? Here are some telltale signs:

Sign #1: Ice forms in the system

When your air conditioner system runs low on refrigerant, the system will not have the necessary pressure to keep the coil’s temperature above freezing. The proper amount of refrigerant and airflow is necessary to prevent the cold coil from freezing over, so a refrigerant leak can cause the system to freeze and form ice.

It’s necessary to check your air filter if you notice ice forming in the system. Dirty air filters can also cause ice to form because they can restrict the airflow to the coil. To check if the freezing problem is caused by your filter, you can shut down your A/C and change the filter. If it continues to freeze, however, it’s best to enlist the help of a professional because this could be the result of a refrigerant leak. 

Sign #2: Your unit is only​ blowing warm air

If your A/C unit starts to blow warm air and can no longer produce cold air, it may be a sign that it’s almost out of refrigerant. This usually happens when the refrigerant leak is rather significant and the refrigerant level is extremely low. 

It’s helpful to check your outdoor unit to check if the refrigerant level is low. One important sign of an extremely low refrigerant level is that the indoor unit blows warm air while the outdoor unit functions normally.

Sign #3: There is a bubbling or hissing sound

If you hear a bubbling or hissing sound, this can likely mean that your refrigerant lines are going through a lot of pressure. A leak will also likely be occurring, which then means you’re low on refrigerant. It’s best to enlist the help of a technician as soon as possible—finding that leak is paramount to keeping your unit intact. 

The Bottom Line

Should any of these signs be present, it’s important to call a professional as soon as you can. You’ll need a refrigerant top-up, which should only be performed with the help of a professional. Failing to meet the proper levels will affect your system, causing it to perform poorly and eventually fail. That said, look out for these signs!
