Buyer’s Guide

Finding the best refrigerant leak detectors should not be a tough task, but with all of the various features and specifications on every single model to take a look at, it can be much more of a headache than you had hoped.

So, to save yourself a lot of time and effort, you should think about these few point before settling on a final purchase. You’ll want a guarantee you will get a good quality item that will last you a long time, and with these tips, you will know how to do just that.

Here’s some things that you should consider before making your final purchase.

Weight

If you are a worker that will be bringing your machine along with you on your job sites, then you’ll likely need something that is easily portable and fairly lightweight.

You wouldn’t want to be carrying around a heavy option all day just so you can lug it into multiple houses or job sites. So, it is important to think about the weight of the machine.

This may also allow you to get a longer-lasting option because it won’t need to be made of plastic to be lightweight enough to take to work with you.

Probe Size

When it comes to refrigerant detectors, the size of the probe can either make things a lot easier for you or turn your simple job into a bit of a nightmare.

If you find it necessary to get into tight spots to be able to locate the source of the leak, then a larger probe can give you a lot of problems. Although it will depend on the different jobs that you do, it is good to get an option that will work for many jobs.

There are flexible probes that offer a long reach and that also is movable enough to get into hard to reach areas that other probes may not be able to.

These may be your best option if you do multiple jobs or projects and need a model that is versatile enough to get most jobs done.

If you only handle a few jobs around the house, or for family members, then you may be able to go with a cheaper option.

Price

Although the price may often be the deciding factor for many people, thinking about what you will actually be getting for your money is important.

You wouldn’t want to spend a large sum on an expensive option just to find out that the product doesn’t work as well as you thought it would.

In the same way, you will also want to check that the inexpensive model you got will not stop working after one use.

Also, if you know you need an industrial-strength choice that will hold up to years of use, then getting a model with a higher price tag may be well worth the higher cost.

Knowing exactly what you will need for the jobs that you’ll be doing is at the heart of all these points, so decide what will be the best bet for your jobs, and you’ll find the best choice for what you need in no time.

FAQs

Now, you will have all of the necessary information in a convenient place without having to research on your own.

How do refrigerant leak detectors work?

These leak detectors machines work by using an alert that comes on when an electrical current is triggered by contact of halogenated gases with the heated ceramic diode.

This electrical current turns on the alarm when it senses the contact and allows you to see the location of the source of the leak.

What happens if a refrigerant leak goes undetected?

If a refrigerant leak is not detected for some time, there can be several different health and air quality issues that can affect you and your family. Freon is tasteless and odorless, but it can cause some serious issues, which is why detecting a leak is so important.

What is a refrigerant leak and what causes it to occur?

A refrigerant leak is a leak that can occur in systems that use refrigerant, like AC units. There can be a plethora of causes of a refrigerant leak, but some of the most commonly seen problems are cracks or holes in the coils.

What signs should I look for to know when I should check for a refrigerant leak in my system?

There are five major signs that will alert you to a leak even. The first is that your system will have a loss of cooling power. The second is that the registers will not be blowing cool air.

However, the biggest way that you may be affected by an unknown leak is that you will see a rise in your cooling bill. A leak will cause the unit to work harder and longer, and this will show up on your heating and cooling bill.
