Ok, first off, I am not an HVAC technician or professional. But, I have been in the construction industry for most of my life and have owned and used a large variety of tools for multiple projects. I recently bought a mini-split heat pump for a medium sized shed I am converting into living space. The unit I bought needed to have the line set vacuumed for install. After calling several HVAC companies in my area, I was surprised to find out that none of them would help me install the unit. They all said they didn't want to void the warrantee but we all know they just want to sell you a unit and mark up the price so they can make a huge profit. One guy did offer to vacuum my line set but said he would charge $1000 to do it! What a rip off! So I looked on Amazon and found this set of gauges and a vacuum pump for a great price. Basically I saved about $850! The gauges are super high quality and the gauge trunk (main body) is made from billeted cnc'd aluminum. All the hoses are high quality as well. The vacuum pump comes with oil so all I had to do was put the oil in and hook up the hoses and I was ready to go. The pump is quiet, high quality, solid, powerful and performed the vacuum duty easily. And it all comes in a nice padded carry case. Highly recommended! I am thinking about recharging the A/C in my truck just so I can use the gauges again lol!

Great price, and worked a charm.

This is good. Does the job. Make sure to tighten everything

they give you enough oil to fill the pump 1/2 full. Mine used oil during pumping. am glad I bought an extra bottle of oil or I could not complete project.
