Your HVAC is Low on Refrigerant — 5 Symptoms

Here are five symptoms that indicate that your HVAC system may need more refrigerant:

Warm Air Coming From Your Vents

If your system is no longer blowing out cold air, this could be caused by a lack of refrigerant in the system. This can be caused by either overuse or a leak.

High Energy Bills

Low levels of refrigerant in your HVAC system can cause it to run inefficiently and use more energy than usual, leading to higher-than-normal monthly energy bills.

Audible Signs

You may hear an unusual hissing sound coming from your vents when you have low levels of refrigerant due to air escaping from the compressor unit as it fails to build up enough pressure for operation.

Ice Buildup or Condensation on Coils and Lines

Refrigerant helps keep the coils cool so that condensation does not form on them; if there’s not enough coolant present, then ice will accumulate on the outside of these components which can lead to other issues with efficiency and performance down the line.

Unusual Smells

If you notice an odd odor coming from your vents, this could be a sign of something wrong with the refrigerant system.

What Should You Do If Your HVAC Refrigerant is Leaking?

If your HVAC system is leaking refrigerant, you need to take action right away. This can cause uncomfortable temperatures in your home and also cost more money on energy bills. If these HVAC low refrigerant symptoms occur, you should call an HVAC company to come to check it out and fix any issues so that your home stays comfortable year-round.


Be sure to check your HVAC regularly so you can be aware of any issues before they become a bigger problem. If you suspect that your system is low on refrigerant, call an experienced technician right away to avoid costly repairs or unsafe conditions in the future.
