Review on 🔧 Optimized Complete Tool Kit for Kozyvacu Mini Split/HVAC/AUTO AC Repair with 1-Stage 4.5 CFM Vacuum Pump, Manifold Gauge Set, Hoses, and Accessories by David Mcdonald

saved me a lot of money. All the crooked AC specialists wanted about $600 to vacuum my 2 mini splits. It cost me about 150 for vacuum and gauges. It was very easy to do. maybe 2 on a scale of 10. That is, if you can get an AC specialist to answer their phone or email. Worked great, saved a lot of money. The only downside is that they give you enough oil to fill up, but according to the instructions, you fill it up, run it for a minute and then drain it. There is probably no more oil to refill. Someone else made this comment, which is why I bought extra oil when I bought the pump from Amazon. nice to see reviews and youtube.
