Window unit AC: Cost to drain right vs scrapping gain (number help)

My 2 Cents..



I am/was in a very similar situation. I started by getting 4-5 HVAC units from a hotel (3-4 times the size of a window unit) and that stack has grown into 20+ along with 4-5 fridges/freezers.
I went to Johnstone University (online classes for Johnstone stores), paid $45 took an 8 hour class thing that consisted of 4 sections which you do at your own pace, used the reviews as study guides, and then went into the Johnstone store to take the actual test (another $45). $90 later I am now universal certified... BUT this method provided me with ZERO hands on experience and I am not 100% sure on the equipment specifics, and have never seen it done in real applications.

What I just did today was reached out to a couple CL ads which were advertising HVAC services, and also to an add that was selling manifolds, rec units, and storage cyclinders. I asked them if they would be willing to travel to my location, spend an hour or so evacuating a few units, and then also purchasing used equipment form them if available. If I can find someone to actually SHOW me how to do it I would be willing to spend $100 or so. Hopefully that is enough to make someone's time worth it.

ALSO! It sure seems like the r22 wont be too hard to sell if I can get the recovery down. Hopefully that will pay itself off eventually.
