I will be going over the main tools that an HVAC technician will need to service units, and replace air conditioning systems. Before I get into these tools the one thing you must have is an EPA 608 certification, as it is against the law to handle refrigerant or work on a air conditioning system without one.
The first tool I will cover will be the gauges. I will be going over the tools needed for repairs on residential homes, so your gauges should be able to read the pressure of r-12, r-22, and r-502. In the future you will need a different kind as r-22 is being phased out but you will get at least ten years of use out of these.
A recovery tank will be needed to recover old Freon from the HVAC unit. If you are replacing a air handler or condensing unit this is necessary, you can also use the old refrigerant to put into the new condensing unit as refrigerant does not go bad.
The way you get the old refrigerant into the recovery tank is by using a recovery machine. The recovery machine takes suction from the HVAC system and puts the refrigerant into the recovery tank. These machines will cost you a pretty buck but they are very well needed to get the job done.
Once the refrigerant is removed from the old system you can cut the copper piping with pipe cutters, and set up the new air handler or condensing unit for installation. Copper piping is joined back together by soldering, so you will need a good set of HVAC soldering torches and solder sticks.
The soldering torches will make it a breeze to connect the copper piping, although a good set up will cost you a bit. Some of the items you should keep in the soldering set up are an inspection mirror, soldering sticks made for HVAC systems, and a roll of sandpaper.
After you have the new system all sealed up by soldering, you will need to get all of the air out of it by using a vacuum pump. The vacuum pump takes suction on the refrigerant lines and removes all of the air and non condensable gases from the system.
A few other tools that an HVAC technician will want to have are a leak detector of some sort. Also a thermostat, a voltage meter, swag tool, and various types of copper fittings to make the soldering process easier.
These are not the only tools that will be needed, there are many more that are out there. Some of them are necessary to have and others are just for convenience. The ones I described above will be used the most, and also are the most expensive and necessary to have for the HVAC technician.
