HVAC Multimeter  Buying Guide.

Best HVAC Multimeter

The first section of our review is exclusively meant to let you know exactly what to do when it comes down to selecting a multimeter that’s meant for Heating Ventilation and Cooling systems.

What exactly is a HVAC multimeter?

Only a handful of people can tell apart the HVAC multimeters from the standard multipurpose multimeter. Whereas the appearance may be the same, HVAC multimeters are different in the sense that they can be able to take readings that are much higher or lower than what you’ll get from the average multimeters.

Besides just being able to take higher readings, HVAC multimeters do have a better design since they are mostly used outdoors. This automatically leaves them subjected to rough conditions which should then be compensated for by the high-quality exterior construction.

In addition to the capability of taking higher readings, you’ll also get accessories that will prove quite useful to you as a HVAC technician such as a backlight at the rear. Others may also have surface temperature probes as well as LED flashlights.

Taking the above into consideration, it’s clearly not easy at all for you to get the best. Even so, consider yourself lucky since in a short while, you’ll have utmost knowledge of how to get your hands on one.

The design- should be lightweight and durable.

You will mostly be holding this multimeter in your palm and it would be best if you went for something that’s lightweight and at the same time does have a compact design.

Whereas it would be quite outstanding to work with a compact and lightweight HVAC multimeter, it would also be better if it had a durable construction. For starters, it should have a rugged design which saves it from wear and tear and even much better, you could go for one that has a rubber guard all around it which would offer utmost drop protection.

Is it easy enough for you to use?

Besides quality construction, it is important that the multimeter you go for be as easy enough to use as possible.

The best HVAC multimeter, for instance should have clear labelling on the front surface. Considering you’ll be using it in rather harsh conditions as compared to the standard multimeter, it is also important that the display be clear enough and the symbols of different electrical units be distinct from each other.

You’d definitely be at an advantage if your multimeter had a backlit display in addition to it just having a large and clear display since this would make it easy to use in dim light conditions.

How much should I spend on the hvac multimeter?

Yet another thing that raises a lot of eyebrows is the amount of money your should spend on the best multimeter.

My take on this is that you first of all pay heed to the question of whether or not the multimeter will be able to meet your day to day demands. Having done so, you can then have a look at price tag and depending on how your budget is, you’ll go ahead and make your purchase.

The more accurate it is, the better off you are

Regardless of how handy and durable a HVAC multimeter is, it won’t do you any good if the accuracy is compromised/ due to this, you should prioritize accuracy above all other things. With the large number of multimeters in the market today, you may easily fall for one that’s really bad on the accuracy. All things considered, such a multimeter will even increase the complexity of your work.

When it comes to choosing an accurate HVAC multimeter, you should, first of all have in mind most of the tasks that you’ll be using to carry out with the multimeter. Having done so, you should go ahead and have a look at the level of accuracy on the multimeter which is normally in percentage in which case the lower it is the better off you are.

It would be even much better if you could get your hands on a true-RMS multimeter the reason being that the level of accuracy is way above average.


Whereas going for a multimeter that can be able to handle most of your daily tasks is advised, you should also consider going for one with additional functions. You never know when you may need to put in some extra effort.

Does the multimeter brand really matter?

When you’re getting one for the first time, you’ll definitely be worried not to select something that will prove disappointing in the long run. 

One of the things that could make a big difference between one that would prove best to you and one that would disappoint you is the brand name. it’s definitely not easy for you to get a brand that will promise, durability, versatility and reliability all in one multimeter.

The few that would do so include fieldpiece, Fluke, Klein and UEI. It is also worth mentioning that these brands have been around for quite a long time which is yet another contributing factory to why they have got the best HVAC multimeter in the market.

Even with the above named brands, you should pay attention to whether the multimeter will meet your most important demands.

Additional features

Just for the sake of convenience, you could go for a multimeter that has some additional features in addition to just handling the important measurement functions.

Some of the things you should look out for include a backlit display which should come in handy in dark areas such as the attic.

You should also look out for an autoranging multimeter. As compared to a manual ranging multimeter, one with the auto range function will come in handy especially when you want to do the work twice as fast.

Other things you should look out for include a temperature probe which would make temperature measurement quite easy.
