XtremepowerUS 3.5CFM 1/4HP HVAC Vacuum Pump R134a R12 R22 R410a A/C Refrigeration Set AC Manifold Gauge R134 Can Tap Carrying Tote

Used for two different heat pump installations: a 18000 Btu and a 6000 Btu and it vacuumed both efficiently - one year apart. So it was still working great after a year in storage. I replaced the vacuum oil after that year - as recommended by the manual. Replacing the oil involves running it for about 15 mins to warm up and loosen the oil, then a hex screw to the front (have something to catch it ready underneath). The hoses and gauges worked for a nitrogen 300psi pressure test as well. Everything seems good quality - and held up to storage for a year in between uses. Would definitely recommend! If you plan on using the gauges for a pressure test, just keep in mind that some newer heat pumps recommend pressure testing at about 500psi which is beyond the accurate range of this gauge.

Purchased to vacate lines on a sedan. Works great and easy to put together.

Product worked as it should. Pump hoses came with connections to fit the minisplit AC I was working on. Nice bag to hold all the product parts for storage. Worth the cost.

I was concerned reading reviews, but after taking the plunge I was able to save myself $1000 in repairing my AC. The thing to note is it came with an old style tap that is not compatible with the new style Freon cans that are self sealing. A nine dollar part at my local auto store and all is ice cold and well.

One word of caution, this kit does not have the new style of t-valve in that it won’t work with the new style Freon cans with a schrader valve. It will work in old puncture style cans. An auto parts store has an adapter for it that’s only a few bucks. Other wise it’s a decent diy set for those who know how to use it.

This item was perfectly priced, functionally as advertised, and delivered on time. I used it to replace the refrigerant in one of my cars and it paid for itself with that one usage.

I received this item on 8/9. Unboxed and attempted to use this item on 8/16-8/18 on my two vehicles. I am experiencing the following issues: 1. The low and high side gauges are not showing consistent readings in terms of pressure on either vehicle. 2. Although the vacuum pump creates a vacuum in the system, when hooking up to R134a cans it will not allow flow into the system via the yellow line. 3. To test if the gauge and lines are working properly, I purchased a seperate single low side gauge and line from the local auto parts store and the R134a worked without issue in refilling using the low side port. When I attempted to contact the company; I was put in an endless loop with a repeating message. Neither Amazon nor the company were willing to replace this item with a working one. After arguing with customer service repeatedly at Amazon - they are finally willing to refund my purchase. No one seemed interested in simply replacing this product. It's a record hot summer here in AZ. Very disappointed that this company isn't willing to stand behind the quality and functionality of this product.

I used this set up to vac-down a mini split A/C Heat Pump. It shipped quick, like with in 48 hours. It was packaged in a shipping box, and in that was a factory labeled sales box, and in that was the unit packed inside it's carrying case. Assembly consisted of, mounting the hanging handle/hook. Adding oil that was included, to the vacuum pump. And I connected the vacuum lines, used some separate adapters I ordered for the vac-down process. Pump was super quiet in operation. Dial indicators all showed clearly and worked in the leak test. No leaks on factory assembled or hose fittings on hoses. Everything fits into is nylon carry bag for dust free storage and or damage. I recommend this system.

Me encantó excelente calidad

Es un buen producto cumple su función ya hice el vacio a dos aires de auto y todo muy bien El único inconveniente q tuve fue en una llave del manómetro esta como barrida cuando la abres ya q no llega a un tope solo es cuando la abro Por lo demás funciona muy bien

Funciona bien, cumple el cometido...por el precio recomendado...

Me ayudo bastante en cargar el gas a mi auto, haciendo vacio a la línea! Muy recomendable!
