A Freon leak is serious business. Not only can it be expensive to repair, but it can also be dangerous. Freon is a refrigerant used in many types of appliances, including air conditioners and refrigerators. If there's a leak, you'll need to get it fixed as soon as possible. 

How can you tell if there's a leak in the first place? The most common way is by smelling it. Freon has a distinct smell, so if you notice an unusual odor coming from your fridge, it could be a sign that there's a leak. This article will discuss the digital tools available to help you find the source of the leak.

What is Freon?

Freon is a colorless gas (called a coolant or refrigerant) that should never give off an odor when an appliance is functioning correctly. It's used in various appliances, including refrigerators, air conditioners and car AC units. The process of cooling in home appliances, like refrigerators and AC units, is made possible by Freon. 

A compressor is used to compress the gas, which is then sent through the condenser to cool it down. The cooled gas is then sent into the evaporator, where it absorbs heat from inside the refrigerator, to keep your food cold, and release the heat from the fridge back to the room.

Does Freon Have a Unique Odor? 

Freon can cause a burning sensation if it comes into contact with your skin. Freon can also be hazardous if inhaled. When Freon leaks, it can cause a sweet or chemical smell. 

Leaking Freon can also damage your appliance and make it less efficient. Inhaling small amounts of Freon is not harmful and will not cause long-term health effects. However, if you are exposed to large amounts of Freon, it can lead to dizziness, headaches, nausea, and difficulty breathing.

How to Detect a Refrigerant Leak

One of the most common appliances in homes is the refrigerator. It keeps food cold and fresh, and helps prevent spoilage. However, like all appliances, refrigerators can develop problems over time. One of the most serious issues is a refrigerant leak.

How to tell if there is a leak:

  • Check for any visible signs of damage to the appliance, such as cracks or holes in the tubing.
  • Look for the presence of an oily residue on or near the AC unit. 
  • Listen for a hissing sound coming from the fridge or AC.
  • You may notice your food is not as cold as it should be, or you may see ice forming on the inside of the appliance. 
  • Take a look at the back of the fridge. If there's any frost or ice buildup, it could be a sign of a leak.
  • Another clue is the smell. Freon has a distinctive smell, so if you notice a peculiar aroma near your fridge, it's worth investigating further.
  • Use a hand-held digital detector to check for leaks.

Tools That Can Detect a Refrigerant Leak

Refrigerant Leak Detector - RLD380L

The #RLD380L Refrigerant Leak Detector has the sensitivity needed for HVAC/R, industrial and automotive applications:

  • Detects R-134a, R-404A, R-407C, R-410A and R-22 (Freon)
  • Includes the replaceable #RS380 semiconductor sensor
  • Color-coded display of Hi and Lo leak levels
  • Hi/Lo sensitivity switch
  • Long, flexible-obedient stainless steel gooseneck probe
  • Fast warmup
  • Redundant audible and visual alarms
  • Ambient refrigerant concentration reset
  • Auto power off

Refrigerant Leak Detector with Pump - RLD400

The #RLD400 refrigerant detector offers a modern, electronic way to maintain mobile and stationary air conditioners, refrigerators, chillers and heat pumps. Its proprietary semiconductor sensor detects many new ozone layer-friendly refrigerants approved under the U.S. EPA’s Significant New Alternatives Policy (SNAP):

  • Detects all commercially available HFC, HFO, HC, HCFC and CFC refrigerants, as well as blends and newly approved replacements such as R-22 (Freon) and R-1234yf
  • Powered by a proprietary sensor with a lifetime of more than 300 hours of operation (ten years of normal use)
  • Triple-redundant leak indication (a loud fast beep, a bright flashing LED, and a digital leak size reading)
  • A true mechanical pump draws in samples, increasing sensitivity
  • Three sensitivity levels
  • Fast warmup
  • Long, flexible-obedient sensor-tipped probe
  • Automatic calibration and reset to ambient levels
  • Mutable beeper
  • Garage-durable construction
  • Made in the U.S.A.
  • SAE J2791 and J2913 certified
  • Complies with European standard EN 14624

If you think you have a Freon leak, it is important to have it repaired immediately by a qualified technician. Otherwise, you could be exposed to dangerous levels of Freon gas.
