Low refrigerant levels are very common and should be adjusted to proper levels immediately. Our technicians will use the superheat or Sub Cool method most manufacturers recommend to adjust refrigerant levels properly. In order for this to be effective, your evaporator coils will need to be very clean. Also, low refrigerant levels are most likely caused by a refrigerant leak somewhere in the system.
Symptoms of low refrigerant are:
- poor or no cooling.
- Iced evaporator coil
- Iced suction line
- Bubbles in the sight glass.
- Outdoor unit cycling on and off too much due to low pressure.
Low refrigerant may also cause equipment to overheat and compressors to burn out prematurely. It is a good practice to have freon levels checked yearly to catch any problems before costly damage occurs.
