AUTO AC Repair Complete Tool Kit with 1-Stage 3.5 CFM Vacuum Pump, Manifold Gauge Set, Hoses and its Acccessories

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.

I bought this set not having done any HVAC work before. I followed instructions I found on U-Tube and was able to vacuum out the lines of my two mini split units. I saved myself over $600 as I was quoted over $300 to leak test and vacuum out each unit. Two critical things to pay attention to:. unscrew the little tab out of the connector that pushes the shrader valve nipple open. If not, you will only create a vacuum in the flexible hose and not the copper tube and you may falsely assume that your copper lines are empty and release the refrigerant into the system only to have air and moisture contaminate your system. The other thing is that when there is much air being evacuated, oil fumes will be discharged. Don't be alarmed, it will clear up once a vacuum is created. If after a while the oil fumes continue to come out, you may have an bad air leak somewhere in your system.

I bought these gauges with one main purpose- to install two mini splits into my home. I planned on taking the pump and gauges to work afterwards, as I am an automotive technician.The whole kit comes in a box and has a small carrying bag. The bag won’t hold the gauges with the lines attached- it all had to be separated. The gauges were zero’d out when they arrived, so no adjustment needed. The kit comes with enough oil to fill the pump once, not enough to fill it twice. Not a big deal, parts stores have vacuum pump oil readily available.I installed the gauges to the vacuum pump, attached the adapter and attached the whole setup to the first mini splits. The gauges feel surprisingly good for this price range, the vacuum pump is heavier than expected (in a good way). I flipped the switch for the pump and it came to life… making almost no noise. The pump is surprisingly quiet, so much so that I had to inspect the gauges to see if the pump was working. Much to my surprise, it had already pulled 25 inches of vacuum. I ran the pump for 2 minutes, and it worked flawlessly.All sounds good, right? So, why the 4 stars instead of 5? Well, I went to shut off the pump and disconnect the gauges from it, and the whole system lost vacuum. I pulled vacuum again, double checked I had the knob turned all the way in to seal the gauges… still lost vacuum. The low side knob does NOT completely seal the system. Not a huge deal- leave the gauges attached to the vacuum pump and call it good. The problem arises when you release some refrigerant to check forLeaks- it will flow right through the gauge and lines, and leak into atmosphere.I pulled a 30 minute vacuum and monitored it for 15 minutes. No leaks, so I disconnected the gauges and released the refrigerant into the system. It’s been two weeks and so far, so good.The gauges get 4 stars, the pump gets a solid 5. The seller gets 5 stars as well, because shipping was fast and it’s a good product.

This pump pulls vacuum as good as big brand units. I used it a few times so far on various vehicles and it has never failed to get all the way down to 29 or 30 in a few minutes. No regrets so far. It's well built, so I think with proper care it should last a long time.

If you know A/C this kit is great I put a 2.5 hr vacuum on a aftermarket install and worked great. Love how you can put in the bag and go.

Product was delivered in timely fashion worked very good made my repair job 100% now have it for future repairs

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!
