Summers in Lebanon, TN, are hot and humid. You’ll need a properly functioning air conditioner to cool and dehumidify your home. A refrigerant leak is a common problem in air conditioners, and it can lead to a major disruption of your comfort. If you notice any of these four signs that your air conditioner has a refrigerant leak, it’s important to arrange for a prompt air conditioning repair.

Long Cooling Cycles

Cooling cycles that last for longer than five minutes suggest the possibility of a refrigerant leak. The air conditioner should be able to cool your home to the temperature setting on your thermostat within this amount of time. A low refrigerant level means the system can’t transfer as much heat out of your home, so it has to work longer and harder.

Poor Temperature and Humidity Control

Refrigerant leaks reduce your air conditioner’s ability to transfer heat. This will leave your home’s air warm and humid. If you feel warm air blowing from the vents and your skin feels sticky, you need a technician to measure the refrigerant level. According to the Department of Energy, refrigerant leaks should be fixed and tested before more refrigerant is added to your air conditioner.

Ice on Coils

A refrigerant leak causes low pressure in the closed-loop system. The low pressure makes the refrigerant in the outdoor unit get unusually cold. If you see frost or ice on the outdoor unit, this isn’t normal. You’ll need a prompt air conditioning repair.

Unusual Sounds

If you hear a hissing sound from your air conditioner, this could be due to an active refrigerant leak. A refrigerant leak could also cause a bubbling sound. If you hear these sounds from the outdoor unit when the system isn’t running a cooling cycle, call for an AC repair.
