Worked as designed

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.

I had ordered a mini split and was just going to use a can of Kwik e-vac but ended up bending and kinking a refrigerant line a little to much and didn't want to take the chance of it failing. So I ended up buying a flaring tool and redoing the lineset thus purchasing this unit to verify that my connections were good . I found a good video on YT on how to use these and this one has been great . I have since used it for two more mini splits and for the price of this vacuum pump,it's 100% worth it just for the confidence and knowing that when you release the refrigerant ,as long as you have verified vacuum and checked everything , that you should have no problems. It came with the adapter for the smaller r410a connection also. Everything fits nicely in the bag and it functioned perfectly. Honestly , spend the money for a vacuum pump just for the extra reassurance as it is less than hoping for the best and then finding out you have a leak and need to evacuate and recharge the system. This worked great for me and I'm really glad I ended up purchasing it as I've used it 3 times already and If I know someone who is installing a mini split , I will be able to use it again . Highly recommended.

Works great, but does not include 1234yf adaptor.

Worked great to vacuum down mini split lines. Only took a minute or two to pull a deep vacuum. Quieter than I expected too. Wasn’t expecting the nice bag that came with it but that is nice too.

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...

Well made ,sold through Amazon in uk but absolutely will not work in uk ,110 v not 240v here in uk,so unless you have a spare 110 v transformer knocking about do not buy in uk .
