BACOENG 3.6CFM Vacuum Pump & Manifold Gauge Set - Home Mini Split/HVAC A/C Refrigeration Kit - Diagnostic R12 R22 R410A - w/Case & R410a Mini Split Adapters

Everything worked great!!The unit comes in one medium box, with the pump in one smaller box and the gauge manifold and hoses in another.This was great because the adapters I needed for the split HVAC came with it, along with a bottle of oil the compressor needed.If I had any issues, it would be that the oil supplied just filled it up to just over half way according to the sight window.I’m not an HVAC guy, so I bought this to use two or three times, instead of paying an HVAC service to come out and check/test the install of the split unit I just installed in my shed and needed this to make sure the lines were good. Good thing I did too! I had a leaking connector, that I had to cut off and re-flare the end on the tubing. I think I saved myself a couple hundred dollars on this install alone.So bottom line: I would buy it again in a heartbeat. For my needs, it will work great!

I found nothing I didn't like about this well made kit. It worked to install my mini split which saved me hundreds. Easy to use and no leaks found. If you have to charge your unit, you may need an adapter for the type refrigerant you use. Nice storage bag heavy duty canvas and heavy duty zippers. I would have liked more of the oil for the pump, but it did fill to the halfway mark, so I have no clue how it uses oil, but it was good for my one use and probably the lifetime... I'm probably wanting too much. So, save some money, watch a Youtube mini split install video, and follow that for your install. This will also help to charge your auto a/c, but I have no idea how to do that. But, now, I'm an expert at pulling and holding a vacuum on a mini split and opening the valves to release the precharged refrigerant. GET IT...

The gauges look great and the hoses are great too. I think they are of very good quality based on my visual inspection and use. After my initial review I noticed that the guages do not read unless a maniford gauge is open (like when vacuuming). I dont think that is correct and the gauage should read with the gauages closed if the ble or red hose is hooked up. Hence I lowered rating from 5 to 4 stars.I pumped the lines and when done completed the installation.

Bought this to install 2 mini splits. Worked like a champ

In the past I've used an installer for my new ac systems, but this time I broke down and bought this set since I have three units to install in the near future and hey, it's not rocket science. There are a ton of great videos online showing how to install a new mini split system. Just the first installation saved me $200 to $300 in installation charges after the cost of this pump and gauge set, so it's already paid for itself and saved me money even if it dies tomorrow. In the future I'll pick up a set of adaptors so I can use it on my cars as well.The pump pulled a vacuum quickly and did not get hot even though I ran it for another half hour to give any moisture enough time to be removed.The gauges are easy to set up and use, and seal very well. I left them connected to the ac system overnight to make sure there were no leaks. Neither the ac nor the gauge set leaked any vacuum.The carry bag is very nice and I was really surprised by the thickness of the fabric and quality. The nylon fabric has a rubber/plastic coating on the inside. This will come in handy if the pump ever leaks a little oil (as they all tend to do).Are there better units out there? Definitely, but they'll cost you three to four times (or more) as much as this one. It's perfect for the DIYer.
