How Often Does a Central Air Conditioner Need Refrigerant?

A central air conditioner unit needs refrigerant only when it begins to leak.

The most common reason for a central air conditioner leak is a problem with the evaporator or condenser coil. If the coils are damaged, they can cause the refrigerant to leak out.

Other common reasons for refrigerant leaks include holes or cracks in the coils, loose connections, or a damaged compressor. If your central air conditioner is leaking refrigerant, you will need to have it repaired by a professional.

The AC Refrigerant Process

1. The air conditioner’s refrigerant absorbs heat from your home’s indoor air, lowering its temperature.

2. The refrigerant then travels to the outdoor unit, where it releases the heat, it absorbed from indoors.

3. The refrigerant returns to the indoor unit, where it begins the process again.

4. If there is a problem with the coils or other components, the refrigerant can leak out, causing the air conditioner to lose its ability to cool your home.

A refrigerant leak signs include:

  • Warm air coming from the vents
  • Higher than normal utility bills
  • Hissing or bubbling noises near the outdoor unit

If you notice any of these signs, it’s important to call a professional to have your air conditioner checked for leaks. Refrigerant leaks cause serious damage to your air conditioner and should be repaired as soon as possible.
