HVAC tools

[MaineShark]

Bacharach electronic combustion analyzer (complete kit, including smoke tester and printer, in addition to the analyzer).  Needs calibration/service from Bacharach, which runs about $300, I believe.  Normally sells for almost $1500.  I won't take less than half an ounce of gold (or equivalent), and I'd like a bit more than that, but it's still well below the new cost, and it was a backup, so it's barely been used (maybe a dozen tests, total, on a device that's intended to do a few hundred a year, and last years doing that).  Add a shop vac and some hand tools, and you're set to clean and tune-up oil or gas furnaces and boilers.

Refrigerant recovery machine.  Older style (ie, not all digital nonsense - simple and easy to understand).  I have no idea if it works, as it was included in a lot of supplies that I picked up, and I don't do refrigerant work, so I've never even turned it on.  Make an offer.

Valveless service tool.  For working on refrigerators and the like, that don't have service valves (just a soldered-closed pigtail).  Allows you to open that up, re-charge the system, and re-seal it.  Make an offer.
