Signs That Your Air Conditioner Needs More Freon Refrigerant

Signs That Your Air Conditioner Needs More Freon Refrigerant

Air Conditioner & Freon

Refrigerant is made from a noble gas called freon, which has properties that allow it to change state from gas to liquid and back to gas again with the help of the AC unit’s condenser and evaporator. This helps cool down the air that is taken in from the outside.

Air Conditioner Running Out of Freon

The only way an air conditioner runs out of freon is if there is a leak in the pipes that carry refrigerant from one part of the unit to the other. But, how do you know if your central air needs freon? Here’s some of the telltale signs.

AC Is Running but the Home Isn’t Cool You might feel warm air flowing through the vents, or you might notice that your AC is weaker than it used to be.

Ice Buildup On Refrigerant Line This happens because the evaporator coil cools down too much, causing cold refrigerant to flow back into the system.

Higher Electricity Bills If you notice a spike in electricity bills, it could be a lot of different things, but if you notice it in conjunction with any of these other problems, it’s likely due to your AC unit having low refrigerant.

Hissing/Bubbling Sound From Refrigerant Most freon leaks are silent, however a large leak can be heard from the refrigerant line. It will make a hissing or bubbling sound. If you hear those sounds, call an HVAC technician immediately.
