5 Signs Indicating Your Air Conditioner Is Low On Refrigerant


The last thing you want during the heat of summer is an air conditioner that isn’t cooling your home. If your unit or system hasn’t been keeping your home as comfortable as it should, low refrigerant, or Freon, could be the reason. The colorless gas turns to liquid as it flows through your air conditioner’s coils, which allows it to cool outside heat and push the resulting cold air into your home. Familiarize yourself with the warning signs of lowered Freon levels so you can schedule timely repairs with your local HVAC contractor. Remember, refrigerant always requires professional handling to prevent injuries and accidents. 


Iced Refrigerant Line

One of the many things that can happen when your air conditioner is low on Freon is refrigerant line icing. Low pressure combined with low temperatures causes this freezing process, resulting in a frigid evaporator coil. Because this symptom can indicate other issues with your ac system, look for other low refrigerant signs before calling your HVAC contractors. 

Hissing Sound

Efficient air conditioners are relatively quiet, meaning they don’t hiss or make other unusual noises. A hissing sound emanating from your ac system indicates a major leak in the refrigerant line and the need to contact your local contractors immediately. Again, do not handle Freon! 

Higher Energy Bills

While energy bills naturally rise in the summer when you have the air conditioner on, serious spikes in utility bills mean something is amiss. Low Freon levels cause this appliance to work considerably harder to keep your home cool, resulting in monthly bills that make your wallet weep. In addition to getting the refrigerant level topped off, look for other ways to keep your bills reasonable, such as using ceiling fans and ensure your home is free of air leaks. 

Warm Air

If your air conditioner blows warm instead of perfectly-cool air, it could have a number of problems including low Freon that cannot sufficiently cool the air before pushing it into your home. Since hot air can also indicate a broken compressor or extremely dirty unit among other issues, schedule an HVAC appointment immediately. 

Low Wait Times

When an air conditioner is working efficiently, it doesn’t take long to cool your home. If the system has been on for a while and your home still isn’t comfortable, it’s likely lacking Freon and needs professional servicing.
