Do refrigerant leak detectors work?
Table of Contents
The heated diode technology used in electronic refrigerant detectors will detect the chlorine or fluorine ions and trigger an audible alarm to identify a leak. Indeed, this technology is less likely to give false alarms compared to corona-suppression.
What is the best Freon leak detector?

How do I know if my refrigerant is leaking?
Simple Ways to Identify & Address a Refrigerant Leak in Your Air Conditioner
- Get a tune-up every year.
- Be suspicious of extra-long cooling cycles.
- Look out for warm air coming from your vents.
- Check for frozen evaporator coils.
- Listen for hissing or jingling sounds.
How do you find a refrigerant leak?
Here are a few ways HVAC professionals might identify leaks in your system.
- Soap bubbles. Soapy water applied to the suspected refrigerant leak will bubble up and give the location away.
- Ultraviolet (UV) dye. Dye is added to the refrigerant, and a special UV light is used to find leaks.
- Electronic leak detectors.
How do you find a Freon leak?
Where do most Freon leaks occur?
Freon leaks are typically found at the schrader valve, valve cores, evaporator coil, copper lines, “U” connectors, weld joints, electrical connection to the compressor body, or the copper tubing. Most of the time, the leak will usually occur in the evaporator coil.
Is it worth it to fix a Freon leak?
If you’ve had the AC for less than 10 years, it’s usually worthwhile to have the leaks repaired—you should still have many good years of life left in the system after this.
Is heated diode or infrared leak detector better?
IR (infrared) detectors detect refrigerant by sampling in a sweeping motion to pinpoint refrigerant leaks. IR sensors zero out of held over a leak. The advantage for IR is it triggers the same for all refrigerants unlike heated diode which work better then some refrigerants than others.
