What Are Signs of Refrigerant Leakage of a Commercial Dehumidifier?

Signs of refrigerant leakage in a commercial dehumidifier can manifest in several ways:

1. Reduced Dehumidification Performance:

One of the most noticeable signs of refrigerant leakage is a decrease in the dehumidifier's ability to remove moisture from the air. You may notice that the humidity levels remain high despite the dehumidifier running continuously.

2. Warm Air from Vents:

If the refrigerant is leaking, the dehumidifier may start blowing warm air instead of cool air. This occurs because the refrigerant is unable to absorb heat effectively, leading to a loss of cooling capacity.

3. Ice Formation on Coils:

In some cases, you may observe ice buildup on the evaporator coils of the commercial refrigerator dehumidifier. This happens when the refrigerant leaks and the pressure and temperature drop, causing moisture in the air to freeze on the coils.

4. Hissing or Bubbling Noises:

Refrigerant leaks can sometimes produce audible hissing or bubbling noises as the gas escapes from the system. If you hear any unusual sounds coming from the dehumidifier, it could indicate a leak.

5. Oil Stains or Residue: 

Refrigerant leaks may leave behind oil stains or residue around the dehumidifier unit or on nearby surfaces. This oil is often mixed with the refrigerant and can be a visual indicator of a leak.

6. Increased Energy Consumption: 

A refrigerant leak can cause the basement dehumidifier with pump to work harder to maintain desired humidity levels, leading to increased energy consumption. If you notice a sudden spike in energy usage without any corresponding increase in dehumidification performance, it could be a sign of a leak.

7. Unpleasant Odors: 

In some cases, refrigerant leaks can produce a chemical odor that is often described as sweet or pungent. If you detect unusual smells near the dehumidifier, it's worth investigating further.

If you suspect a refrigerant leak in your commercial dehumidifier, it's essential to address it promptly to prevent further damage to the unit and ensure efficient operation. Contact a qualified HVAC technician or service provider to diagnose and repair the leak professionally. Refrigerant handling requires specialized equipment and training, so it's not recommended to attempt repairs yourself.
