This vacuum pump was quiet and did the job without issue. It was well worth the money.

Works great

The pump arrived packaged well and oil free. I’m guessing based on reviews there were some at some point that the supplied oil leaked from the bottles? Comes with enough oil to fill to recommended level plus enough to change it at least once-possibly twice. Worked great vacuuming the a/c system on my 2015 Dodge Durango which was my first ever attempt at recharging auto a/c on my own after replacing the condenser which was taken out by road debris getting through the grill. No complaints on the vacuum. Seems to be a solid unit, appears built well, and operates as if it’s well made too. I bought the bigger two stage in case of a need for other possible applications in the future.

It seemed to have an electrical short in it and the pump turned off without kicking off multiple times during first inspection. I unscrewed the handle at the top and checked all of the ground connections and everything seemed fine after I reassembled it, with an added natural kicking-off sound when I flip the switch to the off position. I'm not sure what the initial issue was, but it works great for now.

Replace the fuel seals on my AC system on my vehicle. I ended up losing all the freon due to these leaks. So instead of taking it somewhere I have a set of gauges but I needed a vacuum pump to pull vacuum on the system and make sure it has no more leaks and to dry it out. I settled on this pump I know it's only a quarter horsepower but it does the job. It pumped down the system fairly quickly in about 15 minutes but I let it run for over an hour to ensure it pulled a heavy vacuum to help dry out the system. I let the system sit for about 5 hours make sure I had no leaks. I fill the system with freon and it works great. The nice thing about this pump is it comes with the oil, and there are two type of fittings on the pump one for r22 and one for r143a. The pump construction seems pretty durable although I wouldn't drop it it will probably snap something. The oil is easy to drain and the side Glass is nice so you can see any contamination in the oil. Just make sure when you replace the oil you you vacuum pump oil of a good quality. I imagine after a few uses the oil will become contaminated with moisture. Otherwise this pump work fantastic for my intermittent use for the home mechanic

I recently used this vacuum pump for my home A/C system, and it exceeded my expectations! It’s compact yet powerful, quickly pulling a deep vacuum, which saved me a lot of time. The build quality feels solid, and it’s surprisingly quiet for its size. The pump operates smoothly, with no overheating even during longer jobs. It also has an easy-to-read gauge and a sturdy handle, making it easy to carry and use anywhere. Whether you're a DIYer or a pro, this vacuum pump is an excellent choice for A/C maintenance. Highly recommend it!

Very happy, pulled negative vacuum very quickly, and it's QUIET, at least compared to the 1.5cfm little guy I rented from the auto parts store one time.

I bought this pump in August of 2023 hoping it would/could pull a really good vacuum on the AC repair work that I do. It works and it evacuates but it can't pull a vacuum any lower than -26 psi. So if you are looking for a pump that can pull a deep vacuum in an automotive ac system, this pump isn't it. I tried to save some money by not buying a high quality two stage pump and I regret it now. Like I said, it works and evacuates ok. If this is what you are looking for, then its a good purchase for you.
