Great kit!
Awesome product at an affordable price. The pump is not whisper quiet but it’s not super loud. I was able to get 30in of vacuum on my fridge Freon loop after I replaced the faulty compressor. The additional input port on the yellow hose near the gauges allowed me to install a standard quick connect adapter found on most cars. This allowed me to recharge without disconnecting any hoses therefore eliminating any amount of air from entering the system!!! Really important on a refrigerator. The pump worked continuously for 1hour, it did get warm/hot but never stopped working. I’ll be using this to finally fix the AC on an old dodge as well 👌

Good tool.
Works great. Obviously there's better options out there. However this does get the job done well.

Time to repair your car's AC? Get this kit!
I'm an avid DIYer so when my truck's AC compressor failed, I wanted to tackle it myself so I bought this gauge and vacuum pump set. Be sure to fill the pump's oil before using (included, along with instructions). After replacing all of the mechanical parts (you've got to replace the condensor, receiver/drier, and orifice tube too, after flushing the lines) I hooked everything up, the gauges worked as expected, and it pulled a solid vacuum. The only snag was the freon can tap - it must have had an intenal defect because it wouldn't allow freon to flow from the can. Luckily I had a cheapo tap/gauge combo from the box store and was able add freon and finish the job. I emailed the company via Amazon explaining what happened and they responded early the second business day, stating that they had already shipped a new tap, and they also refunded my $5 for the wasted can of freon. Things happen and sometimes parts fail, so it's great to see a company stand behind their product and do the right thing. You can't go wrong with this kit!

Good Vacuum Pump for DIY
2005 F150 had valve cores leaking. The seals had gotten brittle and shrink over time. Used this vacuum pump kit to vacuum the system after replacing cores. Pump and gauges worked well. Only issue I had is the kit does not come with the valve for self sealing cans. I ended up damaged one of my first refrigerant cans. Had to get a separate adapter not in the kit for the new self sealing cans. AC blows cooled again, saved hundreds.

Good for r134a systems
Very nice kit for a diy person. I just wish there was a little QR code with a video on how to set the gages up and how to fill the vacuum pump with oil. I knew what to do but everyone might not

Do not buy. Lasted one use.
Used this about a year ago to work on my trucks AC. Worked fine. Pulled vacuum. Fast forwards about a year later my other truck needed AC work. Pump died while pulling a vacuum for less than 1 hour. Brand new oil. About 80 degrees outside. Thing could fry an egg it’s so hot. Save yourself the hassle and money. Go elsewhere. Atleast harbor freight will honor their product and replace it. No warranty mentioned for this one. Good luck on getting in touch with the manufacturer. Shoulda bought American.

Excellent high quality pump and kit
Bought this kit because I could not get a plumber to come out the the acreage and commission my slit phase A/C Unit. Does the job very well. Good quality guage set and pump for my needs and pretty much exactly as described. Do not hesitate to purchase this kit...it's great. Don't forget to get the 1/4" adapter mentioned in other reviews to be able to use it on the heat pump valves. Thank you to the other reviewers that made this clear to me when I bought mine. Only plumber that called back wanted $3,000....this pump kit was a lot less lol. Lots of video's on the interweb of how to do this as well....Enjoy.

I am now using this ac unit in my shop it works perfect
Works perfect for the job . I used it to put the ac in vacuum and evacuate moisture from the system . Also used it to add ac to system The gauges and fitting works well . Thanks also for sending oil for the Vacuum pump . The price was affordable also . In my country it get real cold for several month . So most ac system sits for an average of 7 month Most issues with ac here is mainly leaks from shwader valves . So am in business .
