Service tech HVAC tools
Below are the main tool list that a HVAC service technician will use.

To see the basic HVAC tool list check out my basic HVAC tool list post, here I am listing the main HVAC service equipment, which unfortunately is also the expensive ones.

Keep in mind some HVAC companies may supply some of these more advanced tools.
Advanced HVAC Tools List (Service Technician Tools)

  1. HVAC Refrigeration Gauges
  2. HVAC guages
    A set of manifold gauges will be needed to be able to read the pressures in a HVAC unit. Many technicians will carry around two sets of gauges, one for R-22, and one for R-410 and are worried about oil cross contamination. Some HVAC technicians will carry more to put on old units they dont want to use their good gauges on.
    The old analog gauges are slowly being replaced by digital gauges. Old school technicians most likely will never upgrade to the new digital gauges but there are some benefits to them. Like with any of these tools it comes down to personal preference and what you feel comfortable with to get the job done.

    Starting out in HVAC residential than you can get by with a singles manifold gauge set that can read R22 and R410a.

  3. Vacuum Pump
  4. Robinair (15500) VacuMaster Economy Vacuum Pump – 2-Stage, 5 CFM

    Many companies will have a vacuum pump that you can use but there are some that don’t. Vacuum pumps rated by the CFM (Cubic Feet a minute) and stages.

    Stage 1 pumps work but take longer and are a bit nosier.

    Stage 2 pumps can pull a vacuum down quicker and to a lower micron.

    How fast a pump can pull down a unit also depends on the CFM which is how fast it can move air. A 3-5 CFM 2 stage Vacuum pumps are the most common.

  5. Refrigerant Scale
  6. Mastercool 98210-A Electronic Refrigerant Scale

    Refrigerant scales are used to show how much refrigerant a system has taken. A refrigerant tank is set on top of the scale and it shows by weight how much refrigerant has been used. This is important so that you can charge the customer correctly and know the exact amount going into a system.
    Welding and Brazing Torch
    HVAC torches
    Using solder and brazing coppers lines is part of a HVAC technicians job.

    The copper line-sets have to be able to hold a vacuum when put together so getting good at this is key. Most techs use Oxy-Acetylene torches to do this work.

    There are a few techs that will use propane to solder up lines but this is rare most will use Oxy-Acetylene.

  7. HVAC Flaring Tool
  8. Heating and cooling Service technician tool list HVAC
    Some copper line sets will not get soldered but screwed together mainly with Mini-Splits. A flaring tool will be needed to flare the ends and connect them.

  9. HVAC Multimeter
  10. Heating and cooling Service technician tool list
    A good HVAC multimeter will be needed to get accurate readings.

    There are many brands Fluke, Fieldpiece, Klien to name a few.

    I use a Fieldpiece HS36 mainly because I love the Amp Clamp but there are many good ones out there.

    Fieldpiece HS33 Expandable Manual Ranging Stick Multimeter for HVAC/R


  11. Recovery Machine
  12. Robinair RG3 110V AC, 60 Hz Portable Refrigerant Recovery Machine

    Most companies will have a recovery machine already for you to use but it is something to keep in mind.
