Types of HVAC Refrigerant Freon Refrigerant Leak Detectors
- Corona Suppression – Corona Suppression is one of the oldest technology used to detect refrigerant leakage. In this method, the device creates a high-voltage corona on the tip of the detection sensor. When the Corona is interrupted by any of the Refrigerant in the air, then the device triggers the alarm.
- Heated Diode – In the Heated Diode method, the surrounding air is sucked into the machine and then heated to break the molecules of refrigerant apart. When the Refrigerant contaminated air is heated, the molecules of-of Chlorine and Fluorine, which are the positively charged ions will separate. The Heated diode will sense the presence of these positively charged Chlorine and Fluorine ions and trigger the alarm.
- Ultrasonic – Ultrasonic Leak Detectors are one of the innovations in the market. These leak detectors do not sense the refrigerants in the air but detect the ultrasonic sounds from the machine that is leaking the refrigerants. Every leakage has a similar sound, and it is not audible to the human ear. So, these leak detectors will detect the ultrasonic sounds of leakage and trigger an alarm.
In this post, we will share some of the Best HVAC Leak Detectors for Refrigerant leakage checker Reviews.
Why Use HVAC Refrigerant Freon Leak Detector?

How to Choose the Best HVAC Refrigerant Freon Leak Detector: Buying Guide
One must apply the utmost caution while choosing the HVAC refrigerant Freon leak detection methods. There definitely are numerous ways of identifying the exposure levels, but, here’s how you can pick the right method – choose the best HVAC refrigerant Freon leak detector. We bring to you the best buying guide for HVAC refrigerant Freon leak detectors. Look out for the following aspects when purchasing the best HVAC refrigerant Freon leak detector:
If the detector isn’t durable enough, there’s no use in investing in the same. It must remain operational for as long as it declares on the manual (at least). If you feel the quality isn’t up to the mark, choose another model.
Since HVAC refrigerant Freon leak detectors vary in price, it totally depends on the purpose as well as your budget as to which model you’d want to go for. Usually, the price starts at $30 and goes up to around $500.
Type of Detectors
Majorly, there are four types of refrigerant leak detectors namely corona discharge, ultrasonic, infrared, and heated diode. Other than these, there is halide as well as fluorescent (UV) leak detectors. Therefore, choose the one that’s best suited to your requirement.
It is important to maintain the equipment since it is obvious. However, make sure the apparatus doesn’t require you to do a lot in the name of maintenance. Read the manufacturer’s instructions on how to keep up with the detector in the long run so you do not have to invest a lot of time, money, and energy.
How Do Refrigerant Freon Leak Detectors Work?
Here is how refrigerant Freon leak detectors work:
Apart from the electronic detection, keep your eyes open – visual leak detection must not be underestimated. Once you suspect a trickle, get the detector to work and make sure it operates the right way. Start by moving the HVAC refrigerant Freon leak detector in constant motion over the area of leakage. Move the detector back and forth. If you are in the right location, the detector would zero out in a jiffy. Since refrigerants are heavier than air, you may also feel some unusual coldness in and around the target area. Even that’s a quick indicator for you. Also, do not depend on technology alone – use other methods of detection. In fact, a combination proves much more reliable.
In the case of electronic leak detectors, these work on the basis of identifying the acoustics of the leak since it produces some amount of sound. The frequency either comes from high-pressure or low-pressure pipes. These are then picked up by the device from the location of leakage. The signals registered are then transmitted over the security system to take note of and be fixed as soon as possible.
Final words for Best HVAC Refrigerant Freon Leak Detectors Review
These are some of the Best Refrigerant Leak Freon Detectors ranging in different price ranges. If you are looking for a worthy companion to detect residential and industrial leakages, then you should use any of these leak detectors. These Leak Detectors are the best addition to the HVAC Technicians Toolbox.
