Does your home use central air conditioning with forced air? If so, it likely uses refrigerant to cool the air by removing the heat and transferring it outside of your home. This refrigerant plays a key role in keeping your house cool, which is why having low refrigerant due to a leak is a huge concern. Here are some signs that you are dealing with low refrigerant. 

Warm Air

The first sign you are likely to notice is warm air. This is simply due to the air conditioner not being able to do its job because of a lack of refrigerant in the system. Less refrigerant means less heat can be removed from the air, which causes the air to remain warm. You likely have a leak somewhere in the system that needs to be repaired so that more refrigerant can be added.

Insufficient Cooling

Do you feel like your air conditioner is performing insufficient cooling in your home? It may be running a lot longer than normal to get your home up to the proper temperature, or it is not able to keep up with very hot weather. This is a clear sign that the system doesn't have the refrigerant it needs to keep your home at a proper temperature and you should look into it by having an HVAC professional come to your home.

Thankfully, many smart thermostats have a history of how long the HVAC system runs for both heating and cooling. Look at the history and be concerned if you see very long stretches where the air conditioner is constantly running when the outdoor temperatures are not incredibly hot. 

High Electric Bills

An air conditioner that runs a lot longer than normal is going to result in high electricity bills. If you did not notice the lack of cooling or the constantly running air conditioner, you'll likely notice the higher amount that you are paying for electricity. Since your air conditioner makes up a very large portion of your monthly electricity bill, it is worth looking into if the air conditioner doesn't have enough refrigerant. 

Frozen Coils

Believe it or not, frozen coils on an air conditioner are a bad thing. You may think that the coils are doing their job to provide cold air, but the frozen coils are what is preventing the refrigerant from moving through the system to remove heat. Coils are going to freeze due to a lack of refrigerant, so find the leak and you'll most likely prevent the coils from freezing up.
