Summary
  • HVACR technicians use specialized tools for pressure measurement, system evacuation, tubing preparation, refrigerant recovery, and diagnostics.
  • Manifold gauges and vacuum pumps serve key roles in HVACR service, while other tools address installation and diagnostic requirements.
  • NAVAC offers a broad portfolio of professional HVACR tools for installation, service, maintenance, and diagnostics.

HVACR service work requires a range of specialized tools for installation, maintenance, repair, and system diagnostics. Different tasks call for different equipment, from measuring system pressure to evacuating a system or preparing copper tubing.

Manifold gauges and vacuum pumps are two established tool categories used in HVACR service. Other equipment, including tubing tools, refrigerant recovery units, smart probes, and leak detectors, can address additional installation and diagnostic needs.

NAVAC develops professional HVACR tools across these applications, with a product portfolio covering vacuum pumps, manifold gauges, tubing tools, recovery equipment, hoses, and diagnostic instruments.

What Tools Are Used for HVACR Service?

HVACR technicians use different tools depending on the equipment being serviced and the task being performed. Common categories include:

  • Manifold gauges: Used to measure pressure during system service and diagnostics.
  • Vacuum pumps: Used to evacuate HVACR systems.
  • Tubing tools: Used for cutting, bending, flaring, expanding, and preparing tubing.
  • Refrigerant recovery equipment: Used to recover refrigerant from HVACR systems.
  • Smart probes: Used to collect pressure, temperature, and other system measurements.
  • Leak detectors: Used to identify refrigerant leaks.
  • Micron vacuum gauges: Used to measure vacuum levels during system evacuation.

A complete HVACR tool setup can include equipment from several of these categories, depending on the technician’s work and the systems being serviced.

How Are Manifold Gauges Used in HVACR?

Manifold gauges are used to measure pressure in HVACR systems during service and diagnostics. Pressure readings give technicians information about system conditions and can help identify potential problems.

Traditional analog manifold gauges use mechanical displays to provide pressure readings. Digital manifold gauges use electronic displays and can provide additional information and diagnostic functions, depending on the model.

What Do Vacuum Pumps Do in HVACR?

Vacuum pumps are used to evacuate HVACR systems. System evacuation removes air, moisture, and other unwanted substances from the system before it is placed into service or charged with refrigerant.

Vacuum pumps are available in different capacities and configurations. The appropriate equipment depends on the system, the required evacuation performance, and the working environment.

What Types of HVACR Vacuum Pumps Are Available?

HVACR vacuum pumps vary in capacity, configuration, and power source.

Cordless vacuum pumps can give technicians greater mobility when working in locations where access to electrical power is limited.

Smart vacuum pumps incorporate digital functionality into the evacuation process.

Industrial vacuum pumps are designed for higher-capacity applications.

Selecting a vacuum pump involves considering factors such as capacity, portability, power source, and the requirements of the HVACR application.

What Other Tools Do HVACR Technicians Need?

Manifold gauges and vacuum pumps address important parts of HVACR service, but technicians also use specialized equipment for tubing work, refrigerant recovery, measurement, and diagnostics.

Tubing Tools

Tubing preparation is common during HVACR installation and repair. Technicians may need to cut, bend, flare, expand, or deburr tubing depending on the application.

Tubing tools including power flaring tools, tube benders, tube expanders, flare clamps, tube cutters, and other equipment for tubing preparation and connection work. These tools can help technicians perform tubing work with greater consistency across installation and service applications.

Refrigerant Recovery Equipment

Refrigerant recovery is another important part of HVACR service. Recovery equipment allows technicians to remove refrigerant from systems during maintenance, repair, or other service procedures. Under Section 608 of the Clean Air Act, the U.S. Environmental Protection Agency requires technicians who service stationary refrigeration and air-conditioning equipment to follow specific refrigerant recovery and handling practices.

Smart Probes and Diagnostic Tools

Smart probes provide another way for technicians to collect system measurements in the field. Depending on the instrument, these tools can measure pressure, temperature, and other conditions relevant to HVACR diagnostics.
