VIVOHOME 110V 1/4 HP 3.5CFM Single Stage Rotary Vane Air Vacuum Pump and AC Manifold Gauge Set Kit with Thermometer for R134a R12 R22 R502 R410a HVAC Air Conditioning Refrigeration Recharging

This is a great device—easy to use and does the job perfectly. It saves money since you can repair your home cooling system without spending a fortune. This device personally saved me $800, and I highly recommend

The vacuum pump works very well. Well worth the cost.

This vacuum pump paid for itself with a single install of a mini split. Works exactly as directed, with numerous adapters.

I bought this lightly used and worked like a charm. It is a bit loud but that is ok because it is only used for a short amount of time each time. The reservoir was full of oil, that is a good thing, but the bottle was out. I just need to find a bit more of this oil and I am good to go.

Successfully evacuated and recharged our '04 Yukon with this yesterday. I would rate it 5 stars if I didn't have to modify the refrigerant canister taps to make them work. Specifically, it's the rubber gasket inside these taps - they're too thick, which prevents the stem from depressing the valve on the canisters deep enough. My other tap - not from Amazon - is the same way; I suspect they're all like this for some, probably-EPA-inspired reason. I found a YouTube "hack" which worked beautifully: remove that gasket and replace with an o-ring (I happen to have a set of green, automotive o-rings on hand, also from Amazon). This reduced the "headspace" enough for the valve stem to fully penetrate the self-sealing valve on the canister. Also, the low side gauge doesn't read accurately (it's only off by maybe 5mmHg). I hooked up the high side gauge to the low side port to confirm. But it's "good enough" for my purposes, which is maybe one recharge per year :). IT DOES WORK and, for a set that includes both the gauges AND the pump, it's a fair price in my opinion.HOT TIP: once you have your tap installed on the refrigerant canister, screw the valve clockwise (Schrader valves are reversed :) slowly into the can until you hear a hiss. Back it off a tiny bit to close the valve. Once you're all hooked up, open the valve (screw it in) 1 1/2 turns. That seemed to be the sweet spot for my unit, anyway. When I opened that valve too far - i.e. screwed it in two or more full turns - the flow actually decreased somehow. I learned that, in 2018, the EPA mandated that these canisters must ship with self-sealing valves - it's an absurd pain in the backside which has no doubt resulted in MORE escaped gas than the previous, puncture-type canisters. This kit ships with a tap for the puncture type, too, so be sure to use the tap with the BLUNT tip on these post-2018 canisters, not the pointy one :).

I bought this for my husband, and he absolutely loves it! He’s able to charge the A/C on all of our vehicles and even check for leaks—right from home. It’s saved us so much time and money by not having to make trips to the shop for something he can now do himself.The device is easy to use, works efficiently, and gives accurate results. He’s used it multiple times already and has been impressed every time. If you or someone you know likes to take care of their own car maintenance, this is a must-have. Definitely worth the investment!

This Vacuum & Manifold Gauge bundle worked great for me. Hooked everything up. Added specified amount of the provided oil to the compressor, attached other end of hoses to vehicle's a/c lines, plugged compressor in then switched it on. Did it's job well & this set was the best bang for the buck to me.

Used it to for DIY install of ductless mini split. Worked great, easy to use, everything I needed is included.
