Essential HVAC Tools​

When you’re just getting started, your budget is important, and you don’t have endless wads of cash to throw at HVAC tools. In this section, we’ll highlight the most essential, best HVAC tools that you NEED to successfully run your business.

Use these professionally recommended tools from the most-trusted brands to stretch your dollar farther and ensure your money is going towards the best HVAC tools in the industry.

Manifold Gauge​

Arguably the most important HVAC tool you’ll need is the manifold gauge, a pressure-checking system that will help you to complete diagnostics and services.

Take a look at some of the best professional manifold gauge recommendations and their rankings:

  1. Fieldpiece SM480V SMAN Digital Manifold Kit

  5. CPS BlackMax MBH4P5EZ 2V Manifold Gauges

Refrigerant Recovery Unit​

A refrigerant recovery unit removes refrigerants from cooling equipment and stores it in a tank so the refrigerant can be reused after a job. This is an essential HVAC tool because you’ll need it before you can work on air conditioners, freezers, or refrigerators.

Here’s the top five professional refrigerant recovery units:

  1. Fieldpiece MR45 Twin Cylinder Refrigerant Recovery Machine
  2. Appion G5TWIN Twin Cylinder Refrigerant Recovery Machine
  3. CPS Pro-Set TRS600 Twin Cylinder Refrigerant Recovery Machine
  4. Yellow Jacket 95730 YJ-LTE Refrigerant Recovery Machine
  5. Robinair RG3 Portable Refrigerant Recovery Machine

Refrigerant Vacuum Pumps​

In contrast to a refrigerant recovery unit, a refrigerant vacuum pump will help you remove refrigerant from inside a machine and cycle it into a recovery tank.

These are some highly rated refrigerant vacuum pumps to consider:

    • This kit includes SEVERAL necessary HVAC tools:
      • Vacuum pump
      • Manifold gauge
      • Leak detector
      • Carry bag
  2. Robinair 15500 VacuMaster Vacuum Pump
  3. Kozyvacu 5CFM Vacuum Pump

Refrigerant Recovery Tanks​

Refrigerant recovery tanks are used for safely recovering, storing, and transporting used refrigerant from HVAC and refrigeration systems to EPA-certified reclamation centers. Since you can’t vent these tanks into the atmosphere, reclamation centers will either clean the gas and recycle it, or properly dispose of it.

Have a look at some of the top choices for refrigerant recovery tanks:

  1. Flame King 30LB Refrigerant Recovery Cylinder Tank
  2. Mastercool 62010 30LB Refrigerant Recovery Tank
  3. Robinair 34102 30LB Refrigerant Tank

HVAC Thermometer​

HVAC technicians need an HVAC thermometer to read air differences at the supply and return as well as read superheat and subcooling.

When it comes to HVAC thermometers, there are three different kinds: digital thermocouple thermometers, pocket thermometers, and infrared thermometers.

Depending on the type of job, you may choose one or all of these HVAC thermometers. In general, a pocket thermometer is a great tool for getting general readings (e.g. checking your Delta-T, comfort calls, outside air temperature, etc… ).

Whereas, an infrared thermometer is great for getting general readings from hard-to-reach, high up places. However, keep in mind that infrared thermometers won’t work with copper lines because it scatters the sensor.

While it’s a good idea to keep an infrared thermometer handy for generalized readings, it’s important to have a more accurate pocket thermometer for multi-purpose use.

Overall, a dedicated digital thermocouple thermometer is a great, versatile way to have the best of both worlds where accuracy meets versatility.

These are some of the most recommended pocket thermometers from the pros:

  1. Klein Tools ET10 Magnetic Digital Pocket Thermometer
