How To Buy A Multimeter For HVAC?

The market is populated with all kinds of multimeters for HVAC right now. And if you don’t know what you’re doing, you might end up picking the wrong device that doesn’t match your needs/expectations.

Use these factors to arrive at the right multimeter for your HVAC work easily:

Durability (construction quality)

The first thing that defines a great HVAC multimeter is a durable construction. Remember that HVAC stands for or involves working with Heating, ventilation, and air conditioning systems. As such, much of your work will be based outdoors, where you might accidentally drop your device from a height.

To ensure your tool doesn’t get damaged whenever such scenarios occur, it’s crucial that you look for a sturdily constructed model, with excellent shock absorption capabilities.

Lightweight, Compact Design

Besides a durable construction, make sure that model you buy also comes with a lightweight and compact design.

Because you’ll be carrying the tool everywhere with you, in your tool bag, buying a lightweight and compact model will increase its portability. Also, it’ll feel comfortable in your hands.

Accuracy and Reliability

With so many HVAC multimeters on the market today, it’s easy to fall for a product that doesn’t generate accurate results. Needless to say, such a model will make your work harder,

By being extremely careful and watchful, however, you can still find a model that displays accurate results.

Besides, ensure that the multimeter you want to buy comes with all the measurements functions you’ll be using in your day to day job- like current, voltage, resistance, and frequency. Any model with more functions has a higher reliability.

Ease of Use

New to multimeters? If yes, I’d advise you to look for an intuitive model that lets you use it without many headaches.


Multiple brands have introduced their multimeters into the market. Unfortunately, some of them are selling poor meters that do not give accurate results, leave along surviving a fall.

The secret here involves buying from a company that guarantees you’re reliability, dependability, and high performance. Some of the best brands that I recommend you to buy from include Fluke, Klein, Fieldpiece, Milwaukee, and UEI.


A product that comes with warranty shows that the manufacturer has total confidence that their product is reliable and dependable, and will walk you through all your HVAC jobs for years to come.

Additionally, an extended warranty acts as your safety net whenever your products have functionality issues, gets damaged or if you receive it in a damaged state.

In my view, a warranty of at least year for a HVAC multimeter will do. The longer the warranty, the better.


The many multimeters on the market can also be advised along the pricing line- there are cheap as well as expensive models.

But that doesn’t mean that the higher priced models are better than the rest. Basing your purchase on the features that come with the device you want to buy will help you get a great product that falls within your range.

If you want to enjoy the advanced features, you’ll have to dig deeper into your pocket.

Frequently Asked Questions

1. Digital vs. analog multimeter: which one should I pick?

The digital multimeters tend to output more accurate results and are much easier to read than the analog models. What’s more, most professionals are using the digital models today, so you should also consider a digital multimeter for your HVAC work.

2. Can I use any multimeter for my HVAC work?

NO! A HVAC intended multimeter is always recommended as it comes with a different range (to match the range of HVAC systems) from the standard models, as well as other convenient features to make your work easier.

3. What’s the best multimeter for a new HVAC technician?

The best multimeter for HVAC work for a beginner should be an easy to use and affordable model that doesn’t come with complicated features.

4. What if I want to measure large currents?

In such cases, it’d be useless to use your typical multimeter as it has a limited range and might overheat. The best option involves using a clamp meter, whose spring-loaded clamp lets you easily connect the device to the current carrying cable.

5. What’s the work of auto range feature found in most HVAC multimeters?

As the word suggests, this is a handy feature that automatically selects the meter range to make it easier for you to take different measurements.

Tips For Using A HVAC Multimeter

As I promised you at the beginning of this post, I’ll share with you some expert tips on how to use your multimeter correctly.

These tips include:

  • NEVER use damaged probes or test leads for measuring the mains voltage. That’s a hazard!
  • When measuring voltage or resistance, you must connect your multimeter in parallel with the circuit or wire to be tested
  • When measuring mains voltages, it’s always advisable to turn off the power before connecting your probes; if not possible, be sure to connect to neutral first
  • The first step to checking the current or resistance in any given circuit is powering it off
  • Use the series connection when taking current measurements of any circuit
  • Sometimes you’d want to measure large currents which your multimeter range can’t handle. In that case, you’d want to look for a clamp meter to do the measurements conveniently
  • If you measure resistance and your device indicates I on the screen, it means that the resistance value is higher than the set voltage, so you need to adjust it to a higher range
  • When checking the continuity, a buzzing sound/tone indicates continuity. A break in the continuity is usually indicated by digit 1

Final Verdict

Whether you’re a beginner or expert HVAC technician, you must arm yourself with the best HVAC multimeter today. The handy device allows you to easily and accurately troubleshoot the different systems you work with every day. Overall, it makes your work easier and more efficient.

Having shown you how to choose the right HVAC multimeter for your specific needs, I’m confident that you’ll have an easy time buying a multimeter that will make your work easier.
