1. Fieldpiece SRL8 Heated Diode Refrigerant Leak Detector

The Fieldpiece SRL8 is what we believe to be the best refrigerant leak detector to date. It is one of the most highly reviewed and sought after products on the market today. It is created with professionals in mind and is high tech, so the do-it-yourself homeowner might have difficulty using this tool.

Its precision, quality, and accuracy have earned it the top spot on our list of the best refrigerant leak detectors.

Product Highlights

This refrigerant leak detector finds all of the most common refrigerants in the United States, including CFCs, HFCs, HFOs, and HCFCs. The SRL8 has three sensitivity settings; high, medium, and low.

The Fieldpiece SRL8 is also able to detect leaks at 0.10 ounces per year, which is minuscule. The detector makes an audible sound when it has recognized a leak. It then gets louder and begins beeping and flashing as you close in on the exact point of the leak. 

There is no calibration required with the Fieldpiece SRL8, you can literally just unbox this beauty and get to detecting any refrigerant from R410, 134a, 502 or even R22.

What’s to Like About The Fieldpiece SRL8 Heated Diode Refrigerant Leak Detector

The Fieldpiece company has been in the HVAC business for over twenty-five years, earning them a top spot in the industry. This specific model is an easy-to-use heated diode detector, which we love. A heated diode works by taking in a sample of air and heating it. The molecules break apart, and the sensor will detect what ions are in the air. This process is very accurate. 

One of the best selling points of this refrigerant freon detector is its portability. It comes with a rechargeable battery which lasts up to 15 hours, and it comes with both a wall and a car charger! This makes it easy to charge it between jobs and on the go.

Overall, this is an excellent refrigerant leakage detector with high sensitivity.

What’s Not to Like About The Fieldpiece SRL8 Heated Diode Refrigerant Leak Detector

There are very few impactful cons with purchasing the Fieldpiece Heated Diode, but there are a few things to be aware of. 

Over time, the product sensors will burn out, but they can be easily replaced without purchasing a new detector.

The wind is known to cause false leak alerts on this tool and heated diode sensors in general. Although they have done a pretty good job of limiting these false wind alarms, they sometimes occur. 

The Fieldpiece Heated Diode does not detect hydrocarbon refrigerants such as propane, ammonia, or carbon dioxide, but HVAC systems in the United States rarely use these. It also has a warm-up time of about 30 seconds when you first turn it on. 

You do need to install the sensor into the detector before it is ready to use. Many people don’t realize this and wonder why their detector isn’t working when they first receive it. It is not a hard installation by any means, but it is worth noting. 

Lastly, the unit is quite expensive and likely won't be worth the money if you aren’t planning on using it regularly. It does include a one year warranty, though.

BUYER'S GUIDE

There are a lot of things to consider when purchasing the correct refrigerant detector for you. Take these factors into account when buying your next tool.

Refrigerants you Need to Detect 

Determine which refrigerants you specifically need to detect. As discussed above, different detectors find different gasses. There are over 75 different refrigerants used across the world. The most abundantly used refrigerants in America are the halogenated refrigerants: CFCs, HFCs, and HCFCs. 

  • Chlorofluorocarbon Refrigerants, also known as CFCs include R-12,and R-502

  • Hydrofluorocarbon Refrigerants, also known as HFCs include R-134a, R-407C, R-410A, R-438A, R-404A, and R-507

  • Hydrochlorofluorocarbon Refrigerants, also known as HCFCs include R-22, R-401A, R-401B, R-402B, R-408A, R-402A, and R-40A

Also worth mentioning are HFO’s, or Hydrofluoroolefin refrigerants. These are sometimes used as well. 

Find out what refrigerants you need to detect. If you are a homeowner, you only need to get a tool for your specific refrigerant. Contrarily, if you are a contractor or HVAC technician, you will likely need a device that detects a wide range of refrigerants for your different jobs. 

Leak Sensitivity

The leak sensitivity of your tool determines the size of the leak that you can detect. The more sensitivity your instrument has, the smaller the leaks that it can find. 

Note the levels of sensitivity of each different freon leak detector that you are considering. Professionals will want a tool with high sensitivity, while homeowners might not require the same level of precision. 

Battery Life and Sensor Longevity

Battery life is something you must consider when purchasing your detector. If you use a sensor regularly, you won't want to be replacing batteries frequently. If this is the case, consider purchasing a refrigerant detector with a rechargeable lithium battery. 

Additionally, if you are a professional, you do not want your tool to die on you in the middle of a project. If you purchase a battery-run unit, it is smart to carry an extra battery on you while on the job. 

Sensors have different life spans as well. Some sensors are more prone to contamination than others, and some have much higher life expectancies. If you want your equipment to last you a long time with constant use, consider their life spans. 

Quality

Refrigerant leak detectors are not cheap, and you want your investment to last you a long time. You want a high-quality sensor, especially if you are using it a lot.

A well-built, rugged detector will protect itself against accidental drops and damage. Considering whether or not it comes with a carrying case might be necessary for an HVAC technician as well.

Some sensors are more prone to oil seepage and moisture damage than others. Later on in the article, we discuss the different sensor types and which are the most ideal. Warranties are also essential to take into account in case something does happen to your tool. 

Ease of Use

Freon leak detectors do take some time and practice to understand how to use them correctly. Some detectors are easier to understand than others. Some come with highly detailed manuals, while others do not. If you are a beginner or a DIY homeowner, do some research on which are the easiest to use and take that into account. 

It is also essential to look up the cleaning and general maintenance that the required refrigerant leak detector. Refrigerant detectors require care to make them last. You need to keep your freon leak detector free of contaminants to prolong its life. Each leak detector will have a different care routine, and some will take a lot more work to maintain. 

Know the process before purchasing your new leak detector, so you know exactly what you are getting yourself into. 

Price

Price is often the most restrictive of considerations when purchasing anything. While you might want the most superior, top quality leak detector, it might not be in your budget. Consider how often you will be using your tool and how important it is to your overall work. 

How to Know if You Have a Refrigerant Leak

If you find you have a refrigerant leak in your HVAC system, make sure to get it repaired immediately. Failing to do so could lead to severe problems down the line. The first sign that you have a leak is if your air conditioning is not cooling your home as it should. If this is the case, then you, or an HVAC  technician, should take a look at your HVAC unit.

If you notice frozen pipes between your condenser unit and your home, there is likely a leak. The freezing will continue to spread the longer you wait. Eventually, the freezing will trigger the system to shut down entirely, and the ice will melt, often causing flooding in your walls and floors. 

If you notice that your house feels more humid than usual, it could be a sign of a refrigerant leak. Your air conditioner dehumidifies the air as it runs, and if it is compromised, this feature will stop as well. 

If you notice that your air conditioning is running for long periods of time without kicking off, or if you see that your utility bills are unusually high, it is best to take a look at your unit. Additionally, if you hear audible hissing or leaking noises coming from your outdoor HVAC condenser unit, that is a sign of a potentially massive leak. 

The best way to avoid a refrigerant leak is to assess your ACs performance regularly. Get your HVAC system tuned up annually to prevent any expensive repairs over time. Make sure that you have a professional inspect your system and perform pressure tests often. If you do find a leak, get it taken care of as soon as possible.  

Leaks that fail to get repaired can lead to compressor failure, and complete system failure over time. 

Best Refrigerant Leak Detector F.A.Q.

Understanding refrigerant leak detectors can be a bit complicated. Here are some of the most common questions we receive. 

What Is the Best Refrigerant Leak Detector?

There are a wide variety of refrigerant leak detector types on the market. Here are the four best types of electronic refrigerant leak detectors and how they work. 

Infrared Detectors

Infrared detectors are the top type of sensors on the market. An infrared leak detector for refrigerant works by drawing in air samples through an internal pump in the tool. The air samples run across an optical sensor that measures infrared radiation levels in the sample. 

Infrared technology has many benefits. It lasts longer, has more accurate and reliable readings, can find tiny leaks, and does not get overloaded by large amounts of refrigerant. 

Heated Diode

The heated diode sensor works by drawing air through a flexible probe and over the heated sensor. The gasses break down due to the heat and cause changes in currents across the sensor. The differences cause an alarm to sound, alerting you to a refrigerant leak. 

The sensors are susceptible to sensor degradation due to contaminants, such as excess refrigerant, oil, and moisture. They must be regularly checked and have a life sensor life of only 100 hours. 

Corona Suppression

Corona suppression detectors use electric sensors, similar to the heated diode. The refrigerants break the corona, which triggers an alarm and alerts you of a leak. It is an old method that is highly susceptible to contamination and false alarms. Dirt, moisture, dust, and air can set off the alarm falsely, so it is no longer a widely used method. 

Heated Electrolyte

With a heated electrolyte refrigerant leak detector, the air is drawn through a flexible probe to heated electrolytes. The refrigerants react with the electrolytes and alter the currents, triggering a leak. Similar to the heated diode, these sensors are susceptible to contamination. 

Ultrasonic

Ultrasonic refrigerant detectors use sound amplification so you can hear where the leak is occurring. This method is useful for any type of leak, not just refrigerants. However, it is challenging to hear tiny leaks, and it also is hard to use if there is noise in the environment around you.

What is the Most Sensitive Type of Refrigerant Leak Detector?

As mentioned above, infrared is the most sensitive of the refrigerant leak detectors. It has only come onto the mobile leak detection market in the last few years, and it is marginally more accurate and precise than the other kinds. 

The sensor life is expected to last more than 1000 hours. Since the refrigerants never directly contact the sensor (it is broken down by heat before it reaches the sensor), it never contaminates it, making it last much longer than other refrigerant sensors. 

How do you Check a Refrigerant Leak?

The best way to check a refrigerant leak is to use a mixture of different methods. This includes using electronic freon leak detectors, like the ones mentioned above, along with the soap bubble test or a UV light test to pinpoint exactly where the leak is coming from. 

Many refrigerant leak detectors can get you to the exact leak location, but combining it with one of these other methods will make sure you know exactly where the leak has sprung. 

How to Find a Refrigerant Leak Without a Leak Detector?

If you do not have access to a leak detector, there are other ways to find a leak. Though they are not as quick and convenient, they may be just as accurate. 

The Soap Bubble Method

The soap bubble method is one of the most commonly used detection methods apart from leak detectors. If you are an at-home DIY leak detector, this would be the method for you. All you have to do is mix dish soap with warm water. Make sure you mix the solution for several minutes, so it is well combined. 

Next, you pour it on any exposed areas of your HVAC system focusing on where any oil is located. Bubbles will appear wherever there is a leak. You can mark these areas so your technician knows precisely where they need to repair. 

The Dye Method

In this method, you pour fluorescent dye into your system then use a detection lamp to pinpoint where the dye is leaking out. The dye method is an easy and effective way to mark your leak spots, although you will need the correct dye and lamp to carry it out. 

The Oil Method

This method is not as reliable, but it can help you find leak locations. When refrigerant leaks, it often leaks oil with it. Wearing gloves, feel around the components of your HVAC system, and check for visible signs of oil. Oil remnants on your gloves will show you the areas where leaks are probably present.

Where do Most Freon Leaks Occur?

Freon leaks are often found in the evaporator coil. These coils have small capillary tubes that vibrate when the system is in use. The vibrations make it easy for them to develop holes over time and spring leaks. 

Another common place for Freon leaks is in the condenser coils. These coils are U-shaped and are held together with sheet metal tubes. The metal rubs against the top of the coils when the system is on, causing small openings where refrigerant can escape. 

The third most common area is the refrigerant line sets. They often leak at the flare connections or the joints, but they can leak on the line sets if they are hit by something. Weedwackers, lawnmowers, or house workers can often break the line sets. Leaks can also happen if a drywall nail or roofing nail hit the lines.  

FINAL VERDICT

Contractors all across the country agree with us that the Fieldpiece SRL8 Heated Diode Refrigerant Leak Detector is the best HVAC refrigerant detector on the market today.

Its overall design sets it apart from other freon leak detectors in its class. Its sensitivity, accuracy, portability, longevity, and reasonable price point make this our top recommendation for the best refrigerant leak detector on the market today.

In Conclusion

Each of the refrigerant detectors that we reviewed in this article is a high-quality, reliable instrument. Each leak detector has its own unique strengths, whether it is the type of sensor it uses, the reasonable price point, the rechargeable battery, or its warranty.

Also, take into consideration the information provided to decide what would be the best detector for your specific projects.

If you are a homeowner, make sure that you know the signs when attempting to detect a refrigerant leak. Check your system often to avoid having to pay for the potentially expensive expense of refrigerant.

Hopefully, we have helped you understand a little more about the best refrigerant leak detectors, how they work, and which is best suited for you. Good luck with your HVAC repairs!
